ISO-NE Details Regional Energy Shortfall Threshold Metrics

ISO-NE’s Regional Energy Shortfall Threshold (REST) will rely on a pair of metrics intended to capture the intensity and duration of energy shortfall risks in extreme weather scenarios, the RTO told the NEPOOL Reliability Committee on Nov. 19.

The REST project is an effort to define an acceptable threshold for ISO-NE’s seasonal risk modeling, which will use the RTO’s newly developed probabilistic energy adequacy tool (PEAT). ISO-NE is planning to use the REST to evaluate whether additional actions will be needed to support system reliability ahead of winter and summer seasons.

The modeling features a “multiday rolling-horizon economic dispatch,” which includes both preventive and corrective measures from the RTO and incorporates generator opportunity costs. (See ISO-NE Boosts Energy Adequacy Modeling Capabilities.)

In the seasonal outlook for the upcoming winter — which marks ISO-NE’s first time using the PEAT in a seasonal analysis — the RTO’s modeling found manageable shortfall risks. (See ISO-NE Sees Manageable Shortfall Risk for Upcoming Winter.) In the future, the REST and its associated metrics are intended to help standardize this evaluation.

To assess the magnitude of shortfall risks, ISO-NE is planning to calculate the normalized unserved energy (NUE), defined as total shortfall relative to demand, over the most extreme 72-hour cases identified by the model. This will indicate what percentage of load would experience shortfall in the low-probability events identified.

To evaluate shortfall duration, the RTO will calculate the length of the most extreme scenarios, looking beyond the 72-hour window used to calculate intensity.

Mike Knowland, manager of operations forecast and scheduling for ISO-NE, said the duration and magnitude metrics will complement each other and are both “critical metrics for assessing energy adequacy risk under extreme conditions.” He added that ISO-NE “is still evaluating how best to incorporate these two metrics into its REST proposal.”

ISO-NE is still taking feedback on the proposed metrics, and it plans to continue stakeholder discussions on the proposal through January or February of 2025. Once the metrics are established, the RTO is planning to present an initial proposal on risk thresholds in March or April.

The establishment of the REST directly relates to how much the region is willing to spend to limit the potential reliability effects of low-probability weather events, and it could raise tough questions about the tradeoffs between reliability, affordability and decarbonization. ISO-NE has indicated that it expects the states to play a major role in establishing this threshold.

NECEC Agreements

Also at the RC, ISO-NE reviewed the Transmission Operating Agreement and Interconnection Operators Agreement for the New England Clean Energy Connect (NECEC) transmission line.

The 1,200-MW line was solicited by Massachusetts and would facilitate additional imports from Hydro-Québec. Avangrid, the project developer, recently indicated the line has a best-case in-service date of January 2026. (See Avangrid Sues NextEra over ‘Scorched-earth Scheme’ to Stop NECEC.)

ISO-NE is planning to file the agreements with FERC in the first half of 2025 and is seeking an advisory vote from the RC on the interconnection agreement, as well as a vote from the NEPOOL Transmission Committee on the transmission agreement.

The TOA between ISO-NE and NECEC would give the RTO operating authority over the line, which includes responsibility for generation dispatch, real-time balancing, establishing operating limits and exchanging transmission security information to the relevant parties.

The agreement also includes “a standard ‘grandfathered agreements’ provision,” which includes rights of Massachusetts’ electric distribution companies to receive power from the line, ISO-NE said. These rights can be overridden by “short-term reliability actions.”

The interconnection agreement between Hydro-Québec and ISO-NE governs the “coordinated operation and scheduling of energy and ancillary services,” emergency energy exchanges, outage scheduling and the “treatment of inadvertent interchange.”

While the NECEC contracts between Massachusetts’ EDCs and Hydro-Québec are intended to facilitate the one-way flow of power from Canada to the U.S., the line will be capable of sending power in both directions, ISO-NE said. This will allow for emergency south-to-north transmission, although the system impact of these flows still needs to be studied, the RTO added.

The RC is scheduled to vote on the interconnection agreement in January.

Planning Procedure for Data Collection

Steven Judd, ISO-NE manager of resource adequacy and accreditation, outlined the RTO’s proposal for a new planning procedure (PP-14) focused on generator data reporting requirements, which is intended “to provide structure and guidance for lead market participants responsible for reporting monthly data.”

“This procedure will describe the data submission timelines, reporting requirements and validation processes for the required data,” Judd said. He added that standardizing the reporting requirements and guidelines will help ensure system reliability.

The RC will also vote on the proposal in January.

NERC Files ITCS to FERC, Meeting Congress’ Deadline

NERC has filed the final draft of the Interregional Transfer Capability Study (ITCS) with FERC, wrapping up the ERO’s portion of the task set out by Congress in the Fiscal Responsibility Act of 2023 ahead of the December deadline.

The ERO submitted the ITCS on Nov. 19, NERC Director of Reliability Assessments and Performance Analysis John Moura said in a webinar the same day. Next, FERC will post the report for a public comment period; Moura said the starting date and duration of the comment period have not been set.

Following the comment period the commission will submit recommendations for statutory changes, if any, to Congress.

Submitting the ITCS is a “milestone in our ongoing efforts to enhance reliability across” the continent’s electric grid, Moura said. The FRA, passed in June 2023, ordered NERC to work “in consultation with” the regional entities and transmitting utilities to submit the study to FERC by December 2024, leaving the ERO less than 18 months to complete an unprecedented task.

Using a favorite comparison, Moura reminded listeners that “Congress has only asked NERC and the ERO to do two things in our entire history: form ourselves back in 2005 under the … Energy Policy Act, but also to do this study.” As a result, he said, NERC saw ITCS as “on par” in terms of importance with its own charter.

The study comprises three parts, aligning with each major objective set by Congress. Part 1, released in August in draft form, contained an analysis of transfer capabilities between transmission planning regions in North America. The second and third parts were released earlier in November; they provide, respectively, recommendations for prudent additions to transfer capability that could strengthen grid reliability and recommendations to meet and maintain total transfer capability. (See NERC Releases Final ITCS Draft Installments.)

While these components focus on the U.S. grid, Moura said NERC concluded early on that “you really cannot have a credible study without including Canada.” Now that the Congressional mandate has been achieved, the ERO will complete an additional installment covering transfer capabilities and prudent additions from the U.S. to Canada and between Canadian provinces. NERC plans to release the fourth installment in the first quarter of 2025.

Meeting the FRA’s requirements posed considerable challenges for NERC, Moura said. To start with, while the ERO previously conducted regional studies of transfer capability, it never had attempted to do so across the entire grid and never incorporated the efforts of transmission utilities to this extent. The Congressional mandate provided NERC with an opportunity to stretch itself and build capabilities for collaboration that will be useful in future studies, Moura said.

Another difficulty was defining the scope of the study. The FRA described its goals in broad terms but, as Moura explained, narrowing the requirements to a workable framework took some effort.

“We didn’t find ‘prudent’ in our engineering textbooks, so we really had to understand, what is Congress asking us?” Moura said. “The way NERC thinks about ‘prudent’ is really laser-focused around reliability. And so prudent for reliability is what this study is all about. We don’t look at economics, we don’t look at cost-benefit between different projects or different approaches. We’re strictly looking at this challenge from a reliability perspective and remediating the reliability impacts that we see out into the future.”

Markets+ ‘Alert’ Covers CAISO’s Dual Roles as Market Operator, BA

CAISO will be inherently compromised in its role as an operator of a deeper Western market because of its conflicting responsibilities as balancing authority within that market, a group of entities that support SPP’s Markets+ over the ISO’s Extended Day-Ahead Market (EDAM) argue in their latest “issue alert.”

“An organized market that lacks a fully impartial market operator exposes its participants to shifts in hundreds of millions of dollars of economic value, shifts in reliability risk and shifts in environmental benefits because of the actions that the market operator takes or does not take,” the “joint authors” wrote in the Nov. 14 alert, the sixth in a series of seven such pieces touting the benefits of Markets+.

The contributors include Arizona Public Service, Chelan County PUD, Grant County PUD, Powerex, Public Service Company of Colorado, Salt River Project, Snohomish PUD, Tacoma Power, Tri-State Generation and Transmission Association and Tucson Electric Power — all of whom helped fund the Phase 1 development stage of Markets+.

The latest alert is possibly the most technically complex because it focuses on the multi-layered processes CAISO uses to manage operations in its real-time Western Energy Imbalance Market (WEIM), which has grown to cover more than 80% of load in the Western Interconnection since being launched in 2014.

“Over the past decade, in its [emphasis theirs] commingled roles as a balancing authority, transmission service provider and market operator, the California ISO has taken a range of actions and operational decisions for the benefit of the California ISO’s Balancing Authority Area and/or transmission service territory that significantly impact market outcomes for all participants,” the authors write.

In an email to RTO Insider, CAISO spokesperson Anne Gonzales said the ISO is “proud of the integrity and transparency with which we have managed our multiple responsibilities and the many trusting partnerships we have built with balancing authorities, policymakers and other stakeholders across the West” in operating the WEIM.

CAISO’s dual roles in the WEIM have become a recurring point of debate in the competition between Markets+ and the EDAM, particularly in discussions around the Bonneville Power Administration’s day-ahead market participation decision process. (See Rising Tensions Evident at BPA Day-ahead Markets Workshop.)

In the Nov. 14 alert, the joint authors zero in on four complaints from the Markets+ camp regarding CAISO’s operational practices in the WEIM.

Load Conformance

The first of those complaints deals with the WEIM market process known as “load bias” or “load conformance,” which allows a BA to adjust its demand forecast in the hour-ahead scheduling process (HASP) and 15-minute market (FMM) to better position itself for a real-time interval.

The alert contends that as a BA in the WEIM, CAISO has a history of making unusually large upward adjustments to its demand forecasts during morning and evening peak hours “to acquire flexible capacity through additional energy imports rather than explicitly purchasing flexible capacity itself.”

The authors say that while load conformance is available to all WEIM participants, CAISO’s “very large and systemic upward-load biasing” for its territory “appears to be unique.”

As an example, the alert points to a period during a July 2023 heat wave in which CAISO’s average load bias in the FMM during the evening peak was about 1,800 MW but reached as high as 5,000 MW.

“This is a continuation of an ongoing pattern of load biasing for the California ISO service area that first began in 2017,” the alert argues. It adds that “consistently intervening in the WEIM through manual operator adjustments that do not reflect actual system conditions” is likely to increase production costs and market prices in ways that don’t reflect marginal costs, while signaling that market design elements such as the WEIM’s Resource Sufficiency Evaluation (RSE) and flexible ramping product are inadequate to ensure reliability.

The authors also point to a previous statement by CAISO staff that load conformance is “significantly used” by the HASP and FMM “to position resources and secure additional intertie capacity.” But in a 2022 analysis that examined the issue, CAISO said it found “no evidence that load conformance causes a one-to-one increase” in WEIM transfers into the ISO.

It also found that use of load conformance does not improve CAISO’s ability to pass the WEIM bid range capacity and flexible ramping tests, but instead reduces the ISO’s ramp capability, making it more difficult to pass the flexible ramping test.

“The concern that load conformance could create more headroom on CAISO resources by unloading internal resources with increasing transfers was not validated,” the ISO said.

In an interview with RTO Insider, CAISO Director of Market Analysis and Forecasting Guillermo Bautista Alderete said the load conformance actions cited in the alert actually comes with a cost for the ISO.

Alderete said when CAISO applies load conformance in the HASP, FMM or real time, it effectively increases the ISO’s demand requirement.

“That has an effect that is going to dispatch supply up, and the consequence is that the prices are going to reflect that,” he said. “So when we clear the real-time market, the clearing prices are already reflecting the need — that we have asked for additional requirements to clear. It doesn’t come for free, because now the CAISO area — CAISO load — has to pay higher prices because of the consequence of having this load conformance,” which also translates into higher prices paid to exporters into the ISO.

WEIM Transfers

The alert’s second complaint refers to CAISO’s blocking of WEIM transfers “to support California’s reliability.” The alert points specifically to a period over July-November 2023 when the CAISO BAA blocked import transfers from the WEIM in the HASP and FMM — but not in real-time — during net peak load hours.

As the authors note, CAISO’s Department of Market Monitoring (DMM) later said “the transfer limitation had the intended effect of increasing hourly block imports into the CAISO area and decreasing hourly block exports out of the CAISO area to protect reliability during peak net load hours in late July through mid-August.”

The DMM also determined the practice “created a significant, systematic modeling difference between the 15-minute and 5-minute markets, which impacted market results in several ways,” including increasing congestion into the CAISO area from other WEIM areas in the FMM compared with the real-time market, lowering the WEIM’s FMM prices relative to real time in the Desert Southwest and reducing the amount of energy that could be scheduled out of the Southwest in the HASP and FMM.

“While causing adverse consequences across the market footprint, these California ISO operator actions may not have been effective at enhancing reliability in the California ISO’s service area, as DMM found that ‘[u]nder most conditions, it seems that limiting transfers would not provide significant reliability benefits, but would have negative market impacts,” the alert notes.

The joint authors expressed concern that the import limits continued even after initial reliability concerns of late July and early August had passed and by “a lack of transparency” that they were even occurring, saying the first mention by CAISO was in mid-September almost two months after they began.

In a May 2024 presentation to the CAISO Board of Governors and Western Energy Markets Governing Body, the ISO explained that the ISO started the limits after large volumes of WEIM transfers scheduled in the HASP began failing to materialize in real time.

Alderete said a “key piece of information that is typically neglected” is that CAISO was attempting to reduce its reliance on WEIM imports in response to the market behavior.

“We were limiting ourselves to not rely too much on the EIM transfers because from the operational point of view, we wanted to be as clear as possible [about] how much internal supply we could have available to meet our own needs. We were insulating ourselves — basically isolating ourselves — from the rest of the EIM market,” he said.

Alderete said the ISO ceased the practice in November 2023 after it fixed three market issues, including inaccurate display of dispatchable capability in the WEIM, scheduling and tagging processes that allowed participants to ignore export reduction and inconsistent treatment of intertie transactions among BA that increased congestion.

“Limiting the transfers is one of the tools that any balancing area participating in the market has, including … CAISO. We are not the first one to use it; we are not the only one using it,” he said.

‘Limited Transparency’

The alert reprises another common contention by Markets+ supporters: that CAISO can’t be trusted to fairly manage the WEIM’s Resource Sufficiency Evaluation (RSE), which is the market test run ahead of every delivery interval to ensure all participants are making enough capacity available to avoid leaning on the market to meet their energy needs.

They contend that WEIM participants have “limited transparency” into CAISO’s specific inputs and calculations when applying the RSE, which was “routinely failing to identify instances in which” CAISO’s own area didn’t have sufficient resources.

“Even in hours that the California ISO declared an energy emergency, such as during the August 2020 and September 2022 heat events, the RSE still frequently allowed the California ISO area to ‘pass’ the RSE,” the authors say.

This points to a larger problem with the RSE, according to the authors: that a resource-deficient WEIM participant is allowed to continue importing the amount of energy it was importing during a previous interval in which is passed the test, without facing an additional financial penalty. They say the rule is “uniquely beneficial” for CAISO because, unlike other WEIM entities, “it typically begins importing large quantities from the rest of the WEIM in the hours leading up to the afternoon peak, driven in part by the large quantity of upward load bias applied by CAISO operators.”

“This is very different from other WEIM entities that are often importing very little (or even exporting) immediately prior to an RSE failure. Those entities face much more significant limitations on their ability to access WEIM imports without financial penalty,” the alert says.

Alderete countered that RSE rules apply in a uniform way to every BA across the WEIM, including CAISO, and that the ISO has been “very transparent about the design features of that model” and has in recent years undertaken a series of stakeholder policy initiatives to refine the mechanism.

He also said it was “misleading” to contend CAISO faces no financial penalties for failing the RSE, adding that the ISO soon will publish an analysis showing how it did incur such penalties during the past summer.

Congestion Rent Debate Continues

The alert concludes with criticism of CAISO’s treatment of congestion revenue rights (CRR) in its market, a subject that became a kind of proxy for the debate between Markets+ and EDAM supporters after a January 2024 cold snap triggered energy emergency alerts in BAs throughout the Northwest because of supply shortages. (See NW Cold Snap Dispute Reflects Divisions over Western Markets.)

During that event, the authors note, CAISO collected high transmission congestion rents on power flowing across the Pacific AC Intertie (PACI), which is jointly operated by CAISO and entities in the Northwest, but distributed congestion revenues it collected only to its own participants and CRR holders.

“[T]he coordinated physical capability of the multi-state transfer path is modeled by the California ISO using a ‘scheduling constraint’ that is applied as a limitation on the quantity of energy that can be imported into or exported out of California,” the alert states. “California ISO’s choice to model the coordinated limit of the overall multi-state transfer path as a limitation ‘inside’ the California ISO ensures the congestion revenue associated with the overall multi-state path is collected and allocated back to [sic] exclusively to customers of the California ISO.”

The authors say a “similar dynamic” of rent allocation has played out during summer heat waves when CAISO has imported power from the Northwest.

CAISO contested the Markets+ supporters’ assessment practices during a CRR “myth-busting” presentation to the WEIM’s Regional Issues Forum in September. (See CAISO Seeks to Dispel CRR ‘Myths’ Around January Cold Snap.)

And in his interview with RTO Insider, Alderete repeated an argument CAISO has raised previously: that the ISO is the only day-ahead market that provides a market solution to manage congestion, which occurs only south of the “constraint.”

“There is no price signal for doing congestion management in the other northern part of the constraint. That is the problem when you don’t have a market on the other side. There is no mechanism to be able to dispatch, to move resources, to [do] price congestion. All that is basically manually done,” he said.

The joint authors’ seventh and final issue alert will cover “durable customer benefits.”

NYISO Board Approves RNA, 2025 Budget

The NYISO Board of Directors announced at the Liaison Subcommittee meeting Nov. 19 that it had approved the ISO’s 2025 budget and incentive goals. (See NYISO Updates Stakeholders on Budget, 2025 Goals.)

The board also approved two items that have been the subject of intense discussion between stakeholders and NYISO this year: the 2025-2029 Demand Curve Reset and the 2024 Reliability Needs Assessment. (See NYISO Management Committee Passes 2024 Reliability Needs Assessment.)

The board was asked whether it had discussed the issue of the RNA’s finding that expected large, “flexible” loads, primarily cryptocurrency mining facilities, would eliminate an initially projected statewide capacity shortfall. Several stakeholders had expressed skepticism about that as the RNA made its way through the committees.

Chair Joseph Oates said that the board had “engaged” on that topic, but he did not divulge further details. Oates also said that some changes to the DCR that came out of stakeholder oral arguments had been reviewed and considered.

“We can’t share what we changed; you’ll see when we actually make the filing,” he said.

Those will come later this month.

Counterflow: Grid Apocalypse Not

I was minding my own business the other day when the Wall Street Journal ran a special section with the lead article “Five Ways to Disaster-Proof the Energy Grid.”

The article starts out claiming that recent extreme weather has pushed the “aging, overtaxed” grid to its limits, with outages “wreaking havoc on homeowners and businesses.” The alleged culprit is climate change, which is said to get worse.

Flawed Evidence

Steve Huntoon |

The only empirical evidence given for these claims is data from the Climate Central organization purporting to show that widespread power outages have doubled from the early 2000s to the period 2014-2023. The problem with this data is that — per Climate Central itself in an earlier report — stricter Energy Information Administration (EIA) reporting requirements were widely implemented after 2003, so the years 2000-2003 must be disregarded in order to have apples to apples. If one looks at Climate Central’s data for the 10-year period 2004-2013 and compares it with the 10-year period 2014-2023, the average number of outages goes from 78 per year to 91 per year. Not much difference.

An authoritative data source not mentioned by the Journal is the EIA, which has reported average annual hours of outage (aka interruption) per electricity customer from 2013 to 2022. That chart is reprinted here. The bottom part of each column shows the average outage hours without major events (principally weather); these basically are unchanged over 10 years, which suggests the grid is not “aging” and “overtaxed.” My past articles disproving Chicken Little claims about the grid are here and here.

The top part of each column adds the average hours with major events (principally weather). The trend seems up, but not dramatically so.

And let’s put the average 5.5 hours of customer outage in 2022 in perspective. That’s 99.94% reliability (5.5 divided by 8,760). Not “wreaking havoc” on customers — contrary to the Journal’s claim.

Wrong Target

Credibility doesn’t improve with the Journal’s suggested ways to “disaster-proof the grid.” For starters, anyone who wants to know anything about “disaster-proofing the grid” should consult experts at the North American Electric Reliability Corporation (NERC), the Institute of Electrical and Electronics Engineers (IEEE) and the national laboratories.

The experts would explain that more than 90% of customer outages originate on local distribution systems, not the transmission/generation bulk power system (BPS). This is important because all of the Journal’s suggested ways to “disaster-proof the grid” are exclusively or predominantly tied to the BPS. Thus, even if they were sensible (which they’re not, per below), they would have a negligible effect on customer outages.

Now, let’s look at each one individually.

Artificial Intelligence

The Journal’s first suggested way to “disaster-proof the grid” is (of course) AI, which is said to enable better predictions to help better plan for extreme weather. My favorite example is replacing copper wiring with fiber-optic cable at substations vulnerable to flooding. The story says fiber-optic cable is “more resilient to saltwater and can be replaced more quickly if need be.”

Minor problem: Fiber-optic cable does not conduct electricity. Oops!

BTW, if anything will “overtax” the grid, it will be AI. How ironic.

Batteries

Moving on, the Journal’s second way to “disaster-proof the grid” is “bolstering batteries.” Right. I’ve explained why batteries are an incredibly profligate way to provide carbon-free reliability. In May I estimated the annual costs of covering renewable droughts in a carbon-free California relative to other no/low carbon options:

- Long-duration battery storage: $23.9 billion
- Gas plants with carbon credits: $1.1 billion
- Gas plants with CCS credits: $1.6 billion
- Gas plants with CCS retrofit: $4.4 billion

See the difference?

Microgrids

The Journal’s third suggested way is microgrids. OMG. As I explained nine years ago, microgrids ignore the incredible efficiency of grid integration. The latest, greatest microgrid is an incredible waste of ComEd customers’ money.

Microgrids at U.S. military bases actually reduce national security by substituting microgrids for building-specific backup generation that — unlike a base microgrid — is not vulnerable to distribution-level outages (which make up 87% of all base outages) and cybersecurity threats.

Advanced Conductors

The fourth way given is “better, stronger transmission lines.” Yes, we’ve known for years that reconductoring with advanced conductors can increase transmission capacity on existing lines, and I’ve been a fan. But the various options come with their own varying characteristics (such as “rated breaking strength”), as this report shows. Could they somehow “disaster-proof” the grid or even the BPS? No way.

Demand Response

The fifth way given is “controlling demand,” aka demand response. Demand response is best understood as a counterpart to generation resources — reducing demand on command is the flip side of increasing generation on command. Yes, of course, economic demand response should be implemented, just like all economic resources that can be called upon when needed. But DR can no more “disaster-proof the grid” than other dispatchable resources.

The irony is that those ostensibly concerned with grid reliability want to eliminate dispatchable generation resources (gas, oil, coal), thereby enabling, rather than avoiding, future disasters.

OK, I’ll stop ranting.

OMS Survey: Another 1-GW Jump in DERs in MISO Footprint

By the Organization of MISO States’ count, MISO is up to nearly 13.6 GW of distributed energy resources in the footprint.

Results from OMS’s seventh annual DER survey, released Nov. 18, showed an approximate 1-GW growth from the total 12.5 GW of DERs OMS tallied in MISO in 2023. (See Annual OMS DER Survey Records 1-GW Rise in MISO Residential Capacity.) OMS has been recording 1-GW gains in MISO DERs since 2022. Unlike last year, virtually all the DER gains in 2024 came from non-residential sources.

Of the counted DERs, OMS said almost 3.1 GW comes from residential sources, representing a less pronounced, 140-MW climb year-over-year. OMS continues to find that solar and demand response are the most popular forms of DERs across all MISO planning resource zones, constituting 42 and 43% of survey totals, respectively. The organization said, once again, non-residential DERs that are registered with MISO account for the most capacity.

Similar to results from 2023, OMS found the bulk of DERs in Minnesota, Wisconsin, the Dakotas’ Zone 1 and Michigan’s Zone 7. Zone 1 contains about 3.45 GW, while Zone 7 plays host to about 2.75 GW. Those zones individually boast more DER capacity than OMS found systemwide in its first DER survey in 2018 at 2.58 GW.

Mississippi’s Zone 10 once again has the least amount of DERs, OMS found, at just 67 MW.

OMS said several utilities responding to this year’s survey “noted a need for state regulatory direction and the benefits of a common data-sharing platform” for DERs. OMS itself has stressed the need for MISO to take the lead on creating an information sharing platform for DERs as part of the RTO’s compliance with Order 2222. During its board meetings, some OMS members have said MISO’s lack of a standardized system for coordinated DER data sharing is a glaring omission as MISO prepares to accept DER aggregations into its markets.

OMS said most utility respondents reported they’re either implementing or considering implementing advanced metering, demand-side management, a DER management system or another form of improved communication to better use DERs. Most also said their state’s DER interconnection standards need to be updated. Still, the majority said they’re not seeing transmission impacts because of DER growth.

At a Nov. 11 OMS board meeting, Executive Director Tricia DeBleeckere said this year’s DER survey probably showed more DERs because: more utilities responded to the survey; DERs have grown in number; and utilities likely have better tracking and awareness of the resources on their distribution systems.

The utility’s original proposal planned to double the amount of solar energy credits bought through long-term contracts, but that didn’t change the percentage of solar energy within its mix, which remained at 0.5%, the minimum required by the state’s Alternative Energy Portfolio Standards. The 25 MW will be about 1% of the utility’s total energy mix.

King Proposes Refunds for Unused CenterPoint Generators

Sen. Phil King (R) last week filed legislation that would create a process to refund Houstonians for charges associated with CenterPoint Energy’s $800 million lease of generators that went largely unused after Hurricane Beryl.

King’s bill would underscore “the legislative intent of the original bill” by requiring generators leased by utilities to be fully mobile and available for rapid deployment in the aftermath of a storm or other emergency. The legislation would also require the Public Utility Commission to review generators already leased by utilities. Any lease that did not conform to the terms of the bill would be disallowed and its costs unable to be passed on to consumers.

A Houston Chronicle investigation found that CenterPoint has never used the 15 32-MW generators leased in 2021.

Solar Manufacturer Suniva Resumes Production

Officials for Suniva said the solar company has started producing cells at its Georgia factory.

The company had filed for bankruptcy in 2017 but announced last year it would restart its idled Norcross, Ga., factory thanks to incentives in the Inflation Reduction Act.

Suniva began producing test cells over the summer and started commercial production a few weeks ago, the company said. Heliene, a Canadian panel maker with a plant in Minnesota, has started receiving Suniva cells as part of a $400 million deal announced in March, both companies said.

EPA to Charge First-ever ‘Methane Fee’ for Oil, Gas Companies

EPA last week finalized a rule that will charge oil and gas companies a fee for emitting methane above certain levels.

The rule follows through on a directive from Congress included in a 2022 climate law. The new fee is intended to encourage the industry to adopt best practices that reduce methane emissions and thereby avoid paying. As outlined by the EPA, excess methane produced in 2024 could result in a fee of $900/ton, with fees rising to $1,200/ton in 2025 and $1,500/ton by 2026.

However, President-elect Donald Trump is likely to target the fee amid a flurry of expected actions he has promised to deregulate the oil and gas industry.

Global CO2 Emissions on Track to Reach Record Highs

Global carbon dioxide emissions from fossil fuels are on track to reach a record 37.4 billion metric tons in 2024, a 0.8% increase over 2023 levels, according to data from the Global Carbon Project.

The increase was not uniform across the world. Emissions will most likely decline in the U.S. and Europe, while fossil fuel use in China has slowed. That was offset by a surge in carbon dioxide from India and the rest of the world.

A small number of countries account for most of the world’s emissions, with China responsible for 32%, the U.S. 13%, India 8% and the EU 6%.

Exelon Leader Discusses Physical Security Programs

With more hostile actors targeting the U.S. power grid, a representative from Exelon said in a webinar Nov. 18 that taking a “proactive” stance on security is more important than ever for electric utilities.

Speaking at ReliabilityFirst’s regular “Technical Talk with RF” webinar, Mike Melvin, Exelon’s director of corporate physical security, reminded attendees that the ongoing reliance of the U.S. economy on electricity has made power facilities increasingly attractive targets for dangerous people both abroad and at home.

“One important bullet [point] I have been emphasizing over and over with our personnel is, in [a] recent … congressional hearing … it was noted for the first time in modern history that U.S. infrastructure is considered a battle space if we’re ever engaged with a [major] adversary,” Melvin said. “It’s definitely a focus area for people who are not fans of the United States: that if they were … really looking to hurt our country, critical infrastructure is an absolute target.”

Exelon has direct experience with such threats, Melvin noted, with the company’s subsidiary Baltimore Gas and Electric having been the target of a planned attack by two white supremacists before their arrest last year. (See Feds Charge Two in Alleged Conspiracy to Attack BGE Grid.) The FBI accused neo-Nazi leader Brandon Russell and his associate Sarah Beth Clendaniel of plotting to attack electric substations in Baltimore in order to cause a race war in the city and then nationwide. Clendaniel pleaded guilty in September to conspiring to damage electric facilities and carrying an illegal firearm and was sentenced to 18 years in prison. Russell is in custody and set to go to trial next year.

While Melvin credited the “great work by the FBI” for preventing the plotters from carrying out their threat, he said the incident showed how modern technology makes the planning process for such an attack much faster. Even people like Russell and Clendaniel, with no background in electrical engineering or infrastructure planning, can easily access the information they need to develop a potentially effective plot.

“At one point in her life, [Clendaniel] thought it was a good idea to hold up a convenience store with a machete while she was several months pregnant,” Melvin said.

“I would argue that … somebody that would do something like that is not going to be of high intelligence or a sophisticated criminal,” Melvin continued. “And yet, I will tell you, due to open-source mapping that’s readily available, not just in this country but the whole world, they were able to [make] their plans, which was, basically, they wanted to lay the city of Baltimore to waste by cutting out all the power.”

Melvin acknowledged that the electric industry has a history of reacting to incidents, and said one of the biggest challenges for utilities has been working proactively to neutralize threats before they are acted on.

As an example of the progress that Exelon has made in this regard, he cited the company’s personnel security protection program (PSPP). Melvin said these programs have become more common in the industry as utilities have recognized that they “operate in some areas that unfortunately have very high violent crime rates.”

The PSPP includes programs for analyzing crime statistics and identifying “security awareness areas” where personnel are likely to require protection. Melvin said security incidents have significantly decreased since the introduction of the program.

Another threat mitigation program is the facility enhancement program (FEP), which Melvin said is Exelon’s biggest security program so far. The company began the FEP after the armed attack on Pacific Gas & Electric’s Metcalf substation in 2013, in which gunmen fired an estimated 150 rounds that caused the loss of 52,000 gallons of cooling oil. (See Substation Saboteurs ‘No Amateurs’.)

The FEP involves evaluating the utility’s transmission and distribution substations, gas plants, gas regulator stations and other facilities, and assigning each a tiered threat level. Then Exelon makes security upgrades such as fencing and cameras according to the needs of each tier.

Most important, Melvin said, is to make sure the entire organization understands the importance of security and the danger of neglecting details. He recommended ensuring clear communication across all business lines to make sure as few details are overlooked as possible.

“It’s not all about substation security. You can’t have all your eggs in one basket,” Melvin said. “Your security program really needs to be in partnership with your resiliency program, your supply program … your flood mitigation [program], etc. … It’s not a one-size-fits-all approach when it comes to security.”
