RGGI Auction 56 Update: RGGI Auction Clears At $13.90 | Emissions Watch Blog

The most recent RGGI quarterly auction (Auction 56) was held on June 1, 2022. The clearing price was $13.90/ton, three percent higher than the clearing price of $13.50/ton on March 9, 2022 (see Figure 1). Although the clearing price was only slightly higher than the most recent auction, the $13.90/ton price marks the highest clearing price since the start of the program. Notably, the clearing price fell just short of the 2022 Cost Containment Reserve (CCR) trigger price.

NYISO Central East Congestion to Moderate this summer | Congestion Watch Blog

Congestion in April will largely be driven by outage-related transmission constraints, as maintenance for both generator and transmission kicks into gear. Electricity demand across the Northeast RTOs bottoms out in April, moderating demand-driven congestion. However, while warmer temperature forecasts moderate April load expectations in New England and New York, warmer-than-normal April weather is likely to trigger some cooling demand and increased electricity consumption in PJM.

ISO-NE Proposes Ending MOPR in 2025, with a Transition Aimed at Protecting Grid Reliability | Energy News

Ethan Howland reports in Utility Dive that ISO New England has proposed ending its “minimum offer price rule” in 2025, with a transition that exempts up to 700 MW of qualified state-supported capacity — or roughly 2,000 MW of nameplate capacity — from the MOPR over the next two capacity auctions. Learn what Scott Niemann, ESAI Power director and principal, says about ending the rule.

Outage-Related Transmission Constraints to Impact Power Prices in PJM, NYISO & ISO-NE | Congestion Watch Blog

Coal Plant Owners Seek to Shut 3.2 GW in PJM in Face of Economic, Regulatory and Market Pressures | Emissions News

Ethan Howland reports in Utility Dive that power plant owners have started the process of potentially retiring 3,228 MW of coal-fired generation in the PJM Interconnection’s footprint this month, according to the grid operator’s generator deactivation list. Another 1,024 MW of coal shut down last year. Looking at the explanations for the planned retirements, our Julia Criscuolo, ESAI Power’s Manager of Renewables and Emissions, said about a third are driven by environmental regulations, a quarter by unfavorable economics and roughly 20% by “end of life” plant issues.

EPA Wastewater Rules and PJM Coal Retirements | Emissions Watch Blog

Coal-fired power plants are subject to a myriad of federal environmental regulations that have led to significant retirement waves when plant owners face capital expenditures for compliance that cannot be supported by market revenues. Many coal plant owners are now facing significant potential compliance costs due to rules regulating disposal of coal combustion residuals (CCRs). CCRs, also known as coal ash, are produced from the process of burning coal and operating flue gas desulfurization equipment at coal-fired facilities.

Regulations Affecting Coal Combustion Residuals (CCRs) Under EPA Rules | Energy Watch Blog

ESAI Power’s latest issue of EnergyWatch™ discusses regulations affecting coal combustion residuals (CCR) under EPA rules for wastewater discharge and CCR disposal and handling. Several coal-fired plants in PJM have announced retirement plans or are at-risk of retirement due to compliance requirements with these rules. Clients of our Energy Watch service received an accompanying spreadsheet with data about the affected plants. Also included are ESAI’s Power and Natural Gas forward pricing forecasts in PJM, NYISO, ISO-NE.
