Title

Grid operators testify on reliability risks amid rising electricity demand

Purpose

The House Energy and Commerce Subcommittee on Energy held this hearing to question the CEOs and senior leaders of the seven U.S. regional grid operators (PJM, ISO-NE, MISO, NYISO, SPP, CAISO, ERCOT) about deteriorating grid reliability amid retiring dispatchable generation, surging demand from AI data centers and manufacturing, and interconnection backlogs. Members clashed over the role of federal and state clean-energy policy, tariffs on Canadian electricity, and PJM's capacity market price spikes in driving up consumer costs. Begins at0:08:21

Who spoke

Chairman Bob Latta (R-OH)0:08:21: Cited NERC's projection that 52 GW of generation will retire in the next four years0:09:21 and blamed federal and state policy overreach, including the "Clean Power Plan 2.0," for premature base-load retirements0:10:51.

Rep. Kathy Castor (D-FL), Ranking Member0:12:53: Blamed Trump administration funding freezes and layoffs for disrupting grid projects0:14:23, and cited a 10% U.S. tariff on Canadian electricity that prompted Ontario's retaliatory 25% surcharge0:14:53.

Rep. Brett Guthrie (R-KY), Chairman of Energy and Commerce0:17:55: Said NERC projects peak demand to grow 151 GW over 10 years while dispatchable retirements could reach 115 GW0:20:26, warning half the nation is at risk of power shortfalls0:21:26.

Rep. Frank Pallone (D-NJ), Ranking Member of full committee0:23:28: Said PJM capacity prices jumped from $29 to $270 per megawatt-day, adding about $25/month to New Jersey bills starting in June0:25:29, and accused PJM of dragging its feet on reforms0:25:59.

Manu Asthana, President and CEO, PJM Interconnection0:29:32: Said PJM's interconnection queue was cut from 200,000 MW to 67,000 MW0:31:35; described the Reliability Resource Initiative drawing nearly 27,000 MW of applications1:19:06; said EPA's 111(d) rule raised reliability concerns1:07:28.

Gordon van Welie, President and CEO, ISO New England0:34:36: Said the region's interconnection queue is 47% battery storage and wind0:37:37, warned that Trump's offshore-wind pause creates uncertainty for a resource the region counted on by decade's end1:57:00, and said tariffs could cost the region roughly $160 million a year3:08:14.

Jennifer Curran, SVP Planning and Operations, MISO0:38:38: Said MISO created $5 billion in value in 20240:39:16 and approved over $30 billion in new transmission1:41:11; noted wind's winter effective load-carrying capability dropped from 53% to 29%2:20:15.

Richard Dewey, President and CEO, NYISO0:44:03: Said NYISO's latest reliability study identifies violations as early as 20330:46:44 and that the entire NYISO interconnection queue is now wind, solar, and storage2:37:05.

Lanny Nickell, COO (incoming CEO), Southwest Power Pool0:48:45: Said SPP's summer peak was 10% higher than the prior record and demand grew 25% over the last decade0:49:46; cited a June 6, 2024 event where 32,000 MW of wind capacity produced only 100 MW2:23:55.

Elliot Mainzer, President and CEO, CAISO0:53:19: Said CAISO added over 24 GW of new capacity since 2020, including 11 GW of battery storage0:54:19, and that FERC-approved interconnection reforms cut new queue requests by 67%2:58:07.

Pablo Vegas, President and CEO, ERCOT0:58:51: Said ERCOT set an all-time peak of 85,525 MW in summer 20230:59:53 and forecasts demand could reach roughly 150,000 MW by 20301:59:01; noted wind and solar make up 42% of installed capacity while natural gas, coal, and nuclear supply 65% of delivered energy1:00:24.

Key moments

Chairman Guthrie said NERC projects peak power demand to grow by 151 GW over 10 years while up to 115 GW of dispatchable generation retires, a gap equivalent to power for 195 million homes0:20:260:20:56.

Pallone pressed Asthana on New Jersey's roughly $25/month bill increase from PJM's capacity price spike from $29 to $270/MW-day, and Asthana partly attributed New Jersey's supply gap to stalled offshore wind development1:20:361:21:06.

Asthana disclosed PJM's queue reduction from 200,000 MW to 67,000 MW, with another 50,000 MW ready to build and 27,000 MW of new applications in a single week0:31:352:23:07.

Under sharp questioning from Rep. McClellan, Asthana acknowledged gas plants accounted for 70% of Winter Storm Elliott outages in Virginia but attributed local Virginia outages specifically to storm-damaged power lines1:42:181:44:20.

Nearly every witness agreed, when polled by Rep. Fedorchak, that government incentives have a "significant" effect on what generation enters their interconnection queues, and each cited "hold on to existing generation" as their top near-term priority3:01:403:04:42.

Nickell cited a real event on June 6, 2024, when 32,000 MW of nameplate wind capacity in SPP's footprint produced only 100 MW2:23:55.

Van Welie testified New England imports LNG at $35–40 per million BTU despite domestic gas exporting at $6, urging Congress to address the Jones Act as a fix3:16:20.

Vegas confirmed ERCOT has not had to shed load since Winter Storm Uri and detailed a new 765,000-volt transmission buildout to relieve congestion2:51:022:47:01.

Rep. Palmer got PJM, MISO, SPP, and ERCOT witnesses to agree that the Clean Power Plan 2.0 would raise reliability risk in their regions, with Vegas citing 14,000 MW of at-risk coal capacity in ERCOT [1:39:47, 1:21:23 correction: 3:21:23].

Curran testified an automated interconnection-study process nearly replicated in 10 days results that previously took nearly two years1:12:32.
