Transmission Spending by Investor-Owned Utilities 2007-2016 (Source: Edison Electric Institute)
Investor-owned utilities spent $17.5 billion on transmission projects in 2013 and will spend at least $43 billion more through 2024, according to an annual report by the Edison Electric Institute. Of the projects featured in the report, 43% are large interstate projects; 75% support renewables integration; 49% are member-company collaborations with others; and 75% are high-voltage projects 345 kV and above.
NextEra Energy has been named No. 1 among electric and gas utilities on Fortune magazine’s 2014 list of the “World’s Most Admired Companies.” The company, with principal subsidiaries Florida Power & Light and NextEra Energy Resources, said this is the eighth straight year it was named tops in its industry.
NextEra was followed closely in the rankings by Dominion Resources, while Duke Energy, American Electric Power and PPL also made the list.
NRG Buys a Top-10 Solar Roof Installation Business
NRG Energy has acquired Roof Diagnostics Solar, the eighth-largest solar installer in the U.S. Terms of the transaction were not disclosed.
The 475-employee Roof Diagnostics has offices in New Jersey, New York, Massachusetts and Connecticut, and expansion plans for California. NRG is one of the larger solar developers (through NRG Solar) and retail providers of green energy (through Green Mountain).
PPL restarted the Unit 2 reactor at the Susquehanna nuclear power plant last week after a five-day outage for a valve repair. The reactor was being brought online after a planned shutdown for routine maintenance when operators discovered a leak in what the company said was a non-safety-related water supply pump.
Unit 2 has been under increased scrutiny by the U.S. Nuclear Regulatory Commission after four unplanned shutdowns, two with complications, since December 2012. The reactor is one of six in the nation in the NRC’s most serious category, “degraded cornerstone.” PPL is implementing a plan to address the issues under NRC oversight.
Morningstar analysts named Exelon, Dynegy and Pinnacle West as three companies most vulnerable to “a solar-powered ‘death spiral’ roiling the electric industry.” Companies like Exelon and Dynegy will suffer most, the analysts said in a Utilities Observer report, as centralized generation loses value to competitive solar at customers’ homes.
At the same time, the analysts said NRG Energy, Edison International and SunPower are three companies poised to do well in the new environment.
Stakeholders representing load said Thursday they may oppose efforts to change PJM’s $1,000/MWh offer cap, despite a frigid winter in which high gas prices forced the RTO to obtain temporary waivers from the limit.
“We’re not convinced that last winter proves the need to change the cap,” Walter Hall, of the Maryland Public Service Commission, said after PJM officials gave the Markets and Reliability Committee a first read on a problem statement to consider raising or eliminating the cap.
John Farber, of the Delaware Public Service Commission, said he fears costs will quickly rise if PJM raises the cap. “We need fact gathering to determine if there’s a long-term issue here,” he said.
Exelon’s Jason Barker responded that the issue is one of simple math. “There’s no question in our mind that this issue is ripe for consideration,” he said. “PJM’s pricing must be correct so we have an adequate response from generators next winter.”
FERC Actions
On Jan. 24 the Federal Energy Regulatory Commission granted PJM’s request for a waiver allowing make-whole payments for generators with operating costs above the $1,000 cap. PJM said the waiver was necessary to allow some gas-fired generators to cover marginal costs that hit $1,200/MWh in late January, as spot gas prices spiked to $140/mmBtu.
The January order allowed PJM to fund the make-whole payments through uplift charges. On Feb. 11, FERC granted a second waiver eliminating the cap through March 31, allowing high-cost generators to set locational marginal prices.
FERC lifted the cap over the objections of consumer advocates, state regulators and others, who said allowing the RTO’s most inefficient generators to set clearing prices would provide a windfall to the vast majority of generators with costs well less than $1,000.
Moderating temperatures and gas prices rendered the second waiver moot. But Thursday’s discussion — and a surprising report filed by the Market Monitor the day before — suggested the cap’s long-term future will be hotly debated in the coming months.
Problem Statement
PJM’s proposed problem statement says stakeholders should consider lifting the cap because this winter’s extreme conditions had for the first time put the limit at odds with rules requiring capacity resources to offer their output into the day-ahead energy market.
“A large amount of generation was offered into, and cleared, PJM’s energy market at prices likely below the generators’ costs of producing that energy,” PJM said. “The Operating Agreement’s `must-offer’ and `offer-cap’ provisions mean that the sellers were required to offer the available capacity of their generation resources below their marginal costs.”
Most stakeholders agree that it is improper to force generators to sell below cost. But a report that Market Monitor Joe Bowring filed with FERC on Wednesday may further stoke concerns about the risk that raising or eliminating the cap will lead to price gouging.
Monitor’s Review
The Monitor’s report (ER14-1144) covered the period between Jan. 24, when the first waiver took effect, and Feb. 11, when it was superseded by the second.
The only day during that period that resulted in waivers was Jan. 28, when seven generators owned by three companies sought relief.
The Monitor reviewed the requests at FERC’s direction and concluded that all but $9,118 of the nearly $584,000 in requested make-whole payments should be rejected.
The Monitor rejected requests to include the 10% “adder,” which is typically included in offers based on the uncertainty of calculating operating costs for combustion turbines under changing ambient conditions. “It is not appropriate to include the 10% adder in make-whole payments to generation owners in this situation because it is not an actual cost and the generation owners did not pay it,” the report said.
The report said all seven of the units requesting waivers purchased gas for less than the estimated price on which their cost-based offers were based and that five of the seven had better heat rates than what was reflected in their requests. Three of the generators withdrew their requests in response to the Monitor’s challenges.
The report said one generator purchased gas at a price 45% less than the estimate on which it based its waiver request. “When combined with an actual heat rate 4% better than included in the waiver request and removal of the 10% adder, the actual cost of the unit was about 52% lower than the cost included in the waiver request, lower than the $1,000/MWh offer cap,” the Monitor said.
The Monitor is conducting a broader review of all price offers by gas units in January to identify any evidence of overcharging. That review could result in recommendations that PJM seek refunds, Bowring said.
Lengthy Debate Predicted
PJM’s Adrien Ford, who presented the problem statement, said PJM agreed with the Monitor’s calculations on the waiver requests.
Ford said she hoped the Market Implementation Committee could complete work on the problem statement within three months, a timeline she acknowledged was “optimistic.”
Load representatives predicted a longer debate.
“I think this is going to be a tough issue from the customer perspective,” said Susan Bruce, of the PJM Industrial Customer Coalition. “We are still digesting what happened” over the winter.
“From the perspective of the consumer advocates this is a very touchy issue,” agreed Dan Griffiths, executive director of the Consumer Advocates of PJM States (CAPS).
Bowring, too, cautioned that three months might be too ambitious a time frame for a full review. He said that it might be too early to say if any substantive change is necessary. “If it turns out our investigation shows this is a one-off, you don’t want a permanent solution,” he said. “You want a one-off waiver.”
The issue would be assigned to the MIC under PJM’s proposed Issue Charge. The proposals are expected to be brought to a vote at the MRC’s next meeting.
Former Federal Energy Regulatory Commission Chairman Jon Wellinghoff responded to criticism of his role in publicizing information about potential for attacks on the power grid Friday, telling Politico he had done nothing wrong.
Wellinghoff came under attack over a Wall Street Journal article describing an internal FERC report that described possible grid attack scenarios. Wellinghoff was not named in the Journal article as the source of the report, but he discussed it for an earlier Journal article on the subject. (See FERC Criticism of Ex-Chair Mounts.)
The former chairman told Politico that the information in the Journal article was no secret. “There was no classified information,” he said. “There was no secret information and nothing was shared with anybody that was in any way part of some unpublished report.” He and another FERC official had briefed hundreds of people about the study, Wellinghoff said.
Sens. Mary Landrieu, D-La., chairwoman of the Energy and Natural Resources Committee, and Lisa Murkowski of Alaska, the committee’s top Republican, sent the Department of Energy’s inspector general a letter last week asking for an investigation into the leak. Murkowski also named Wellinghoff on the Senate floor, criticizing him for participating in the Wall Street Journal story with “sensational,” possibly “reckless” comments.
GRID Act Gives FERC More Power to Deal With Threats
Sen. Ed Markey, D-Mass., and Rep. Henry Waxman, D-Calif., reintroduced legislation that would give FERC more authority to protect the transmission system from security threats. FERC last month ordered the North American Electric Reliability Corp. to identify critical facilities and propose standards to protect them. But spurred by ongoing concern about attacks on the power grid and recent publicity about the potential threats, some in Congress want to go further.
The Grid Reliability and Infrastructure Defense (GRID) Act would empower FERC to issue emergency orders if an imminent security threat is identified. It also allows FERC to issue protective orders on its own if it determines that NERC has not adequately addressed an identified vulnerability. Under current law, FERC must only act on reliability standards that NERC submits to it.
The bill would also allow FERC to ensure there are enough spare large transformers available to “promptly replace” any that are damaged in an attack. The measure also requires the president to identify up to 100 defense-critical facilities vulnerable to disruption of power supply provided by an external provider. If FERC determines a vulnerability that is not adequately addressed, it may issue a rule to protect it. The bill is similar to one that passed the House of Representatives in 2010 but did not succeed in the Senate.
PTC May See Senate Panel Action Starting This Week
Windmills (Image credit:123RF Stock Photo)
Senate Finance Committee Chairman Ron Wyden, D-Ore., hopes to start action Wednesday on a package of measures to extend energy tax incentives, including the production tax credit (PTC) for wind power. Wyden, who became chairman of the committee in February, is a strong supporter of the PTC.
It is unclear whether tax extenders would win full Senate approval, particularly in this election year. If the measures must be part of a full package of tax code rewrites, the negotiations will be complex. In the House of Representatives, Ways and Means Committee Chairman Dave Camp, R-Mich., may be open to discussing tax extenders but said he still wanted to keep pressing toward comprehensive tax reform. The PTC for wind, one of a number of tax incentives for the energy sector, expired at the end of last year.
Republicans on the House Energy and Commerce Committee, who oppose the Environmental Protection Agency’s upcoming regulations limiting greenhouse gas emissions from power plants, are surveying grid operators about the role coal plants play in their markets and reliability.
In a letter to PJM and other transmission operators, the lawmakers said they want to know what could happen if coal plants produced less or closed because of the EPA’s rules. Their concern was sparked by the gas and electricity price spikes this winter, they said.
Chu: ‘Don’t Get FedExed,’ Get Into Rooftop Business
Former Energy Secretary Steven Chu has advice for utilities: Instead of looking for protective rules and rates, they should get into the rooftop-solar business themselves. Utilities are in danger of being pushed out, he said, “like the Post Office got FedExed.”
Chu said utilities should consider leasing rooftop installations to homeowners. “This is not a radical model. This is the old telephone system model,” he said.
PJM is considering ways to simplify the sharing of real-time generator data to improve situational awareness and help transmission operators respond more quickly in emergencies.
AEP’s Dana Horton urged the Markets and Reliability Committee Thursday to consider changing the current rules on data access, which he said are cumbersome and time consuming.
Horton said transmission operators would “like to be able to see real-time megawatt hour output from all generators in the PJM footprint, like PJM control operations folks do. They’re dealing with a lot of transmission overload issues. If they could see more output data, for more of the region that impacts their area, they are better able to give feedback.”
Horton said the current procedure for obtaining data access, spelled out in Manual 14D, “looks like it was written in the 1950s. It refers to making copies in triplicate.”
State Estimator (Source: ETAP)
Phil Hoffer, an AEP transmission operations manager, said the data would be used as an input to AEP’s state estimator. “Some units may be outside of our control area but have significant impact on our operations,” Hoffer explained.
PJM officials said the RTO supports the effort. “We should be as transparent as we can,” said Executive Vice President for Operations Mike Kormos.
CEO Terry Boston noted that PJM found other transmission operators’ state estimators helpful during the September heat wave, particularly for understanding conditions on lower voltage systems.
PJM Market Monitor Joe Bowring said he would support streamlining the sharing rules if it were done in a way to preserve confidential information. Existing confidentiality agreements and codes of conduct should satisfy any confidentiality concerns, AEP said.
The MRC will be asked to vote on AEP’s issue charge and problem statement at its next meeting. If approved as is, the issue would be assigned to the Operating Committee.
The Markets and Reliability and Members committees approved the following measures with little or no discussion last week:
Markets and Reliability Committee
Changes to Manual 14A: Generation and Transmission Interconnection Process, which updated Attachments F & G. These attachments list wind turbine models that do not need to be reviewed by PJM prior to submission of system impact and generation interconnection feasibility studies. Units listed reflect those PJM has modeled in the past.
Revisions to PJM’s Tariff and Operating Agreement to update the list of agreements and transmission service transactions to which PJM Settlement, Inc. is not a part.
Operating Agreement and Tariff revisions in preparation for eSuite application name changes. These revisions include changing eSchedule and Enhanced Energy Schedule (EES) to InSchedule and ExSchedule, respectively, in the documents. This is part of a larger refresh of eSuite tools, which will occur in stages through the end of the year. (See PJM Updating eSuite Apps.)
Updates to the Regional Transmission and Energy Scheduling Practices for the deployment of ExSchedule. The changes remove ramp reservation and tag timing requirements based on schedule duration. These changes were requested in part due to the new Coordinated Transaction Scheduling (CTS) between PJM and NYISO, which aims to reduce uneconomic flows between the RTOs. (See NYISO Scheduling Product Wins FERC OK.)
Changes to accelerate the schedule of the triennial review of the Cost of New Entry (CONE) by two months. The change, which was also approved by the Members Committee, will move the deadline for staff recommendations to May 15 from July 15 and the projected FERC filing to Oct. 1 from Dec. 1. The CONE review will be conducted every four years beginning with the 2018/2019 Delivery Year.
Members Committee
Tariff revisions associated with CTS and export transactions. The key change is the addition of a provision stating that export transaction screening will not apply to emergency transactions between PJM and neighboring balancing authorities.
Members reacted warily Thursday to PJM’s proposal to develop a generic transition mechanism that would hold capacity providers harmless for future rule changes.
PJM’s Adrien Ford told the Markets and Reliability Committee that the proposal was prompted by the transition mechanism approved by members to protect generators whose installed capacity ratings are reduced by seasonal verification tests. (See Transition Period OKd for Seasonal Verification Rules.)
Bruce Campbell, of demand response provider EnergyConnect, said the proposed solution, based on the Manual 21 fix for generators, may not provide protection for DR.
“This mechanism is really impractical” because it assumes the impact of the changes can be predicted, Campbell said. “We often don’t know what the impact of the changes will be.”
Susan Bruce, of the PJM Industrial Customer Coalition, said she prefers “stability” in capacity market rules. “It might make rule changes too easy to contemplate,” she said.
Exelon’s Jason Barker said his company had “reservations about a `one size fits all’ solution.”
Barker said “it would certainly be helpful to have a default” transition mechanism. But he said it should be spelled out in manuals and not the Tariff or Operating Agreement, where changes would require Federal Energy Regulatory Commission approval.
Katie Guerry, of DR provider EnerNOC, agreed, suggesting the mechanism not be a “defined solution but a set of parameters that must be abided by.”
Ford said PJM officials attempted to address DR in drafting the problem statement. “We wanted to make sure it works for all types of capacity resources,” she said.
Financial Transmission Rights holders asked PJM and Market Monitor Joe Bowring last week to take action to address the continuing shortfall in FTR funding. They received sympathy but no commitments.
In June, the Federal Energy Regulatory Commission rejected a complaint (EL13-47) by FirstEnergy Solutions Corp. that sought to bill all transmission users to make up the shortfalls. While PJM largely supported FirstEnergy’s proposed solution, the Monitor rejected it as “simplistic” and unfair to load.
The commission urged PJM and its stakeholders to reach a consensus solution and to work with its neighbors to reduce congestion on the RTO’s borders. In August, the commission granted rehearing in the case, keeping the docket open but offering no timetable for further action.
$1.1 Billion
In the interim, market participants say, the problem has only gotten worse. Cumulative shortfalls have grown to more than $1.1 billion (see chart). DC Energy’s Bruce Bleiweis told the Members Committee Thursday that March “could be the worst ever.”
“It’s a problem that hasn’t gone away,” said Bleiweis. “We’re still looking for action.”
PJM introduced FTRs in 1999, intending them to provide a financial hedge against the costs of day-ahead transmission congestion.
The value of an FTR is based upon the difference between the day-ahead congestion price between a specific source and sink. The quantity of FTRs to be auctioned is supposed to be limited by transmission capacity.
But a PJM stakeholder report found that revenues were falling short because pre-auction modeling failed to capture some transmission outages and deratings. The modeling also could not account for market-to-market flowgates added in the middle of a planning period.
Consensus Elusive
Since the report, PJM officials have worked with MISO to reduce congestion resulting from cross-border flows.
Last spring, stakeholders also approved two modeling changes recommended by the Financial Transmission Rights Task Force that were expected to provide modest improvements. But members were unable to reach consensus on others, including several proposed by the Monitor. (See MIC Rejects Change to FTR Long-Term Auction Modeling.) The task force was disbanded in December.
With no solutions coming from the stakeholder process and no action from FERC, Goldman Sachs’ J. Aron & Co. seized upon PJM’s ad hoc creation of a pricing interface in the ATSI region during the Sept. 10-11 heat wave. PJM’s action, intended to make demand response set prices in the area, exacerbated underfunding by $23 million over the two days, J. Aron said in a filing in the FirstEnergy docket in December.
Top Binding Constraints in FTR Auctions and ARR Allocations (Source: State of the Market 2013, fig. 13-1)
FTR holders found a new opportunity to bring the issue up when Bowring gave members a presentation on the 2013 State of the Market report, which also criticized the creation of such interfaces.
Harry Singh, of Goldman Sachs, said market participants used to be able to buy 1.2 or 1.3 FTRs for a path they were looking to hedge, but that the technique no longer works because the level of underfunding varies significantly from day to day. On Feb. 14, for example, the funding was only 30%; on Sept. 10 and 11 it approached zero.
In 2010, load serving entities converted almost 63% of their Auction Revenue Rights (ARRs) to FTRs, Singh said. In 2013, only 31% did so. “That tells you people think it doesn’t work as a hedge,” Singh said. Instead, he said, the market has become a way to speculate on uplift and the level of underfunding.
Sympathy, No Commitments
Bowring and PJM CEO Terry Boston acknowledged the problem but were noncommittal about pursuing solutions.
“I’m almost certain the stakeholder process is not going to come to a resolution on this issue,” Boston said. “But we need to keep it on the table.”
The State of the Market report declared the FTR market performance competitive. But it said the market design was flawed because it “incorporates widespread cross subsidies which are not consistent with an efficient market design and over sells FTRs.”
The Monitor noted that the market has responded to the shortfalls by reducing bid prices and increasing bid volumes.
Clearing prices for FTR obligations averaged $0.30/MW in planning year 2013/14, down from $0.71/MW in 2010-11. FTR obligation sell offers dropped to $0.05/MW down from $0.22/MW over the same period.
The report reiterates eight recommendations Bowring made in an April 2013 filing in response to the FirstEnergy complaint.
Bowring said the eight recommendations could increase the FTR payout ratio to almost 96% from the current rate in the mid-70s. The recommendations included a reduction in the allocation of ARRs, the elimination of portfolio “netting” and using probabilistic analysis to improve transmission outage modeling.
In response to a question from Bleiweis, Bowring said he had considered making a Section 206 filing to win FERC approval for his proposed changes. “It’s really a question of timing,” Bowring said, adding that he’d like “to see if others will join us” in support.
PJM’s day-ahead prices for last Thursday turned out to be far more modest than they initially appeared.
The RTO reposted the day-ahead results for March 27 after officials identified an error in the input data used to clear the market. A value of 350 MW was used for the West Interface instead of 3,500 MW for hours 8 through 23, causing incorrect prices and quantities in the day-ahead market solution.
A glum Stu Bresler, vice president of market operations, informed stakeholders of the error at the end of Thursday’s Members Committee meeting. In reposting the results, Bresler said PJM was invoking a provision put in the Tariff “with the hope that we’d never have to use it.”
The changes reduced prices by as much as $37/MWh, with the biggest changes seen in the AECO, BGE, JCPL, METED, PECO, PPL and PSEG zones. In the PPL zone, for example, the LMP for hour 20 — originally posted at $89.41 — was reduced to $52.16.
Bresler said yesterday that the error resulted in higher day-ahead dispatch orders for some generators east of the West Interface and lower orders for those to the west, but that the actual dispatch of the units in real time was unaffected.
Bresler said the apparent constraint at the West Interface “didn’t bind that hard, so it wasn’t enough to raise a red flag” before the day-ahead results were initially posted.
He said officials are investigating whether they can add an automated check to prevent such errors in the future. “We certainly don’t want the market to think this is going to be a regular occurrence,” he said.
The Federal Energy Regulatory Commission has scheduled a hearing over how much Duke Energy will pay to resolve its obligations for transmission expansion projects in MISO after settlement talks collapsed.
Administrative Law Judge Philip C. Baten ordered a prehearing conference for April 1, in preparation for a scheduled Oct. 21 hearing in the case (ER12-91), which resulted from the move by Duke Energy’s Ohio and Kentucky utilities from MISO to PJM in May 2010.
In September, FERC rejected a settlement by Duke’s affiliates, ruling that the agreement unfairly imposed transition costs on transmission customers who were not party to the agreement. (See FERC Rejects Settlements over ATSI, Duke Moves to PJM.)
Baten ordered the case to hearing after the parties indicated at a settlement conference March 10 that they were at an impasse.
WASHINGTON — Tony Clark, the junior member of the Federal Energy Regulatory Commission, rarely says much at the commission’s monthly meetings. On Thursday, however, he became the latest of his colleagues to criticize former Chairman Jon Wellinghoff’s crusade to bring attention to physical threats to the grid.
Clark made a pointed reference to Wellinghoff in praising acting Chair Cheryl LaFleur for leading the commission to issue a rule March 7 directing the North American Electric Reliability Corp. to develop measures to protect the grid from physical threats.
The order was prompted by concerns raised by the April 2013 attack on Pacific Gas and Electric’s Metcalf substation.
Former FERC Chair Jon Wellinghoff
“As all of you who work with FERC know, the chairman at any given time shoulders the responsibility of directing the drafting of orders and deciding what will be circulated to his or her colleagues for approval,” Clark said in a prepared statement. “In all honesty, something along these lines could have and perhaps should have been done months, if not several years ago …”
Wellinghoff, who was chairman from 2009 until December, has been widely quoted in news accounts since leaving the commission in a campaign to raise awareness of the threat of sabotage. He has called the Metcalf attack “the most significant incident of domestic terrorism involving the grid” to date.
Wellinghoff, now a partner at law firm Stoel Rives LLP in San Francisco, did not respond to a request for comment last week.
Norris, Moeller Criticism
At the commission’s February meeting, Commissioners John Norris and Philip Moeller warned that Wellinghoff’s public statements, which were featured in articles in TheWall Street Journal and several California newspapers in February, could result in copycat attacks. Norris also warned against overreacting to the threats, saying it could lead to wasteful spending. (See FERC, NERC: Don’t Overreact to Sabotage Threat.)
LaFleur did not criticize Wellinghoff’s actions but said she agreed with her colleagues that “the resilience of the grid needs to be viewed broadly.”
Critical Substations
The Journal’s Feb. 5 article also reported Wellinghoff saying that a FERC analysis found that “if a surprisingly small number of U.S. substations were knocked out at once, that could destabilize the system enough to cause a blackout that could encompass most of the U.S.”
On March 13, the Journal published a second article reporting details from a confidential FERC analysis — apparently the same one Wellinghoff had referred to in February — that concluded the country’s entire grid could be shut down for weeks or months if only nine substations were sabotaged.
The newspaper did not identify the locations of those substations or its source for the study.
The article said that FERC had conducted power flow analyses on the most critical 30 substations among 55,000 substations nationwide. It reportedly concluded that disabling just nine substations — four in the East, three in the West and two in Texas — could send the nation into darkness.
The Journal said it had reviewed a memo prepared by Leonard Tao, FERC’s director of external affairs, that summarized the study’s findings: “Destroy nine interconnection substations and a transformer manufacturer and the entire United States grid would be down for at least 18 months, probably longer,” said the memo.
Wellinghoff also commented for the March 13 article. “There are probably less than 100 critical high voltage substations on our grid in this country that need to be protected from a physical attack,” the Journal quoted Wellinghoff. “It is neither a monumental task, nor is it an inordinate sum of money that would be required to do so.”
Leak of Report Condemned
That article drew harsh condemnation. “Whoever is the source of this leak — and it appears to be someone with a great deal of access to highly sensitive, narrowly distributed FERC documents — is clearly putting our nation at risk,” Sen. Lisa Murkowski (R-Alaska), said in a statement. “If his or her actions are not illegal, they should be.”
LaFleur, in a statement the same day, acknowledged the newspaper had not identified the critical substations but condemned it for publishing “other sensitive information.”
There may be value in discussing steps to keep the grid safe, she said, but “the publication of sensitive material about the grid crosses the line from transparency to irresponsibility, and gives those who would do us harm a roadmap to achieve malicious designs.”
NERC issued a statement saying “Articles like the one in The Wall Street Journal today do nothing to improve security, rather they jeopardize it.”
Clark last week did not criticize the Journal but did “find fault with those people who may possess sensitive or confidential information, and then choose to release it.”
Costly Investments
At least two gunmen were believed to be involved in the attack on PG&E’s Metcalf 500/230 kV substation near San Jose. The shooting caused more than $15 million in damage, idling the substation for nearly a month, but no power interruptions. (See Substation Saboteurs ‘No Amateurs’.)
FERC told NERC March 7 to develop standards within 90 days that require transmission operators to conduct risk assessments to determine what facilities could have a critical impact on grid operations if damaged by saboteurs. The standards will also require operators to evaluate their vulnerabilities and implement security plans to protect the critical equipment. (See FERC Orders Rules on Grid’s Physical Security.)

PG&E said last month it plans to install opaque walls, advanced camera systems, enhanced lighting and additional alarms at multiple substations as a result of the attack. Although it did not place a cost estimate on the improvements, it said it would likely seek a rate increase to fund them.
Dominion Resources Inc. said last month it plans to spend $300 million to $500 million over the next decade to increase security of its facilities. It would include two levels of perimeter security featuring “anti-climb” fences and key-card access systems for substation yards.
Earlier this month, a TV station in Richmond, Va., reported that state troopers had begun guarding two Dominion substations in Dinwiddie and Hanover counties. Dominion said there have been no threats to any of the company’s facilities.
NextEra Energy has been named No. 1 among electric and gas utilities on Fortune magazine’s 2014 list of the “World’s Most Admired Companies.” The company, with principal subsidiaries Florida Power & Light and NextEra Energy Resources, said this is the eighth straight year it was named tops in its industry.
NRG Energy has acquired Roof Diagnostics Solar, the eighth-largest solar installer in the U.S. Terms of the transaction were not disclosed.
