NEW ORLEANS — Three years after the region’s integration, MISO South, with its plentiful gas generation, constrained interface into the North and capacity for severe weather, still doesn’t feel fully “in” the RTO, speakers told the Gulf Coast Power Association’s MISO South Regional Conference on Thursday.

Jennifer Vosburg, president of Louisiana generating at NRG Energy, said MISO’s North-South transfer constraint under the RTO’s settlement with SPP limits South’s participation in North. “It’s a challenge to how competitive MISO South continues to be,” Vosburg said.

“The drive to integrate into MISO was, ‘We’re going to be fully in MISO,’” Vosburg said. “We’re proud that the Planning Resource Auction limit is 600 MW more this year. That’s not fully integrated … MISO South is not on the same playing field as MISO North.”

Multiple panelists said the constrained North-South interface has exacerbated an “illiquidity” issue in MISO South.

Plentiful capacity in South is unable to help shortage conditions in North, Vosburg said, and South will remain isolated until it can fully participate in the market. She added that since integration, it is often easier to sell in the PJM capacity market than participate in MISO’s capacity market.

Vosburg said MISO’s once-thriving independent power producers have become “a lonely table.”

Paul Zimmering, an attorney at Stone Pigman who has represented the Louisiana Public Service Commission, said the North-South transfer limit should have been examined by MISO much earlier than its currently underway footprint diversity study. “This is 2017, and we were hoping this would have been looked at earlier. We thought that we would get an evaluation earlier on, but it’s happening now and it’s great,” Zimmering said.

However, Zimmering said MISO is doing a good job through its Transmission Expansion Plan playing catch-up on other transmission projects in the Entergy territory that were ignored prior to the incorporation of MISO South. He said 86% of Public Utility Regulatory Policies Act qualifying facilities in South now participate in the MISO market.

“One MISO is a goal, and I don’t think we’re there just yet,” he added.

Zimmering also said regulation challenges exist in MISO South, where states — Louisiana, Texas and Arkansas — are located in both SPP and MISO. “There are a lot of — I wouldn’t call them divided loyalties — but different interests to look out for,” he said.

MISO President and CEO John Bear pointed out the $2.3 billion in transmission investment since MISO South’s addition in 2014 and said the RTO has created almost $2.5 billion in total savings over the region’s three years of existence.

The value “is real and it’s happening, and I think it’s a really good story,” Bear said.

Although the region hasn’t experienced a hurricane since integration, operations have withstood significant weather events, Bear said: tornados in northern Arkansas in 2014; a Texas dam at risk because of heavy rains in 2015; flooding in eastern Texas and Louisiana; and persistent regionwide heat in 2016.

Matt Brown, vice president of federal policy at Entergy, said MISO’s footprint-wide climate differences are a benefit to MISO South, allowing lower planning reserve margins. Brown said Entergy operating companies saved about $412 million in 2014 and 2015 after joining the RTO. Transmission investment in MISO South has doubled from $359 million in MTEP 14 to $886 million in MTEP 16.

Jim Schott, vice president of transmission for Entergy Louisiana, said the company has noticed that the RTO can better identify congestion for future projects and has sounder congestion management practices, decreasing instances of transmission loading relief (TLR).

“Since December of 2013, TLR and [local area procedures] have hardly been uttered once,” Brown said.

Schott also said MISO membership means Entergy plans projects further in advance to fit into the annual MTEP schedule.

He also made a case for allocating costs of economic transmission upgrades to benefiting local resource zones alone. The RTO is considering changing cost allocation for economic projects in time for 2018, when costs can be shared with MISO South. “Benefits generally flow to some region, and the region should bear those costs,” he said.

Ted Kuhn, consultant at Customized Energy Solutions, said integration has brought pricing transparency — and added bureaucracy — to MISO South. “It takes time to get things through a larger process. It takes time to know which stakeholder meetings to go to, which person to talk to. It’s a process that will kill you if you don’t know it,” he said.

SPP Seam and MISO South

Laurie Dunham, vice president and manager of regional planning for Duke-American Transmission Co., said SPP and MISO need better coordination of the models in their joint studies. She urged stakeholders to get involved in interregional planning meetings.

Dunham said large-scale transmission projects aren’t always needed to resolve reliability issues, and, in some cases, the addition of “2 to 5 miles of line and a reactor” eliminates a problem.

Patrick Clarey, a FERC attorney adviser, noted that SPP is facing challenges with greater wind penetration. MISO and SPP’s possible overlay study, designed to last through 2019, could produce transmission projects to solve SPP’s problem, he said. (See related story, SPP Eyes 75% Wind Penetration Levels.)

Ted Thomas, chairman of the Arkansas Public Service Commission, said his state is in a good position — for now.

“It’s easy to be in my position when gas prices are low. Our utilities aren’t stirred up, our customers are satisfied, the legislature is calm,” Thomas said. However, he added, “if the last three weeks are any indication of the next three years, administrations will change, federal policies will zig-zag … and the consumer needs to be protected throughout.”

MISO South and the Climate

Thomas said the electric industry’s long 30- to 40-year capital cycles create a high risk of stranded costs. He said with Arkansas, Texas and Louisiana’s low-cost energy when compared to California’s prices, MISO South can wait to implement more expensive and experimental carbon-reduction measures.

“We can’t stick our heads in the sand. But we can wait and see. We don’t have to take the risk that the high-cost states take,” Thomas said. “I know that carbon is a long-term problem, and I question if we have a solution. I know that some states have a political appetite to reduce carbon, but I also know that Arkansas, and I suspect Louisiana, aren’t those places,” Thomas said. He added that even if Arkansas eliminated carbon emissions by 2018, it would not be enough to impact global temperature rise.

Other panelists maintain that MISO South is ripe for increased renewable penetration and more energy efficiency programs.

Siobhan Foley, the City of New Orleans’ FUSE Executive Fellow for Climate Action, said solar has come down dramatically in price and now is viable in terms of cost. She said MISO South can reduce carbon through several smaller solar projects. “It really is about smaller wedges and more of them, sharing and distributing in different ways,” Foley said.

Dunham said that the Clean Power Plan’s uncertain future should not stop the adoption of renewables and storage. “I don’t think it’s ever ‘pencils down.’ We need to be always modifying and adapting,” she said.

Low Rates, High Bills

Some officials think MISO South could do with more energy efficiency programs to reduce the region’s high energy consumption.

“We have low rates, but we have really high bills,” said Logan Atkinson Burke, CEO of consumer advocate Alliance for Affordable Energy. She said Entergy New Orleans customers have among the highest energy use rates in the country.  Mississippi, Alabama and Louisiana rank among the worst in the country in available energy efficiency programs.

Thomas said energy efficiency programs can help defer “big decisions” and capital expenses by keeping demand low.

Jeff Baudier, chief development officer of Louisiana-based Cleco Holdings, said the company’s addition of a heat recovery steam generator to the Cabot coal plant in the St. Mary Parish in Franklin, La., will add 50 MW of capacity with no additional emissions. The project is expected to be in service in the first quarter of 2018.

Ted Romaine, director of origination for renewable generation developer Invenergy, said commercial and industrial customers, especially Internet companies like Google, Amazon and Facebook, are increasingly making off-site renewable energy deals such as virtual power purchase agreements.

“This is a market that’s really picked up steam in the last few years. … We see more buyers come into the market, and interest continues to grow. This isn’t a Silicon Valley-exclusive market,” Romaine said.

ERCOT, SPP and PJM lead in corporate off-site renewable deals with a 77% share of the U.S. and Mexico, Romaine said. He said although MISO doesn’t have any such contracts, it will in the future. He expects more than 20 first-time corporate renewable buyers nationwide in 2017. He added that vertically integrated MISO South utilities might bend to pressure from big energy users such as Google to create green tariffs — renewable energy purchasing programs — even if they have no legal obligation to do so. He said there is “strong potential” for solar-based virtual power purchase agreements in MISO South.

“If we don’t start recognizing that multinational corporations have sustainability agendas, they’re going to go somewhere else,” Baudier said.
