MISO’s Independent Market Monitor said a MISO South September transmission emergency shows the RTO needs a better handle on constraint management within its markets.

ISO-NE received six proposals from four different companies in response to its request for proposals to address transmission constraints and interconnect onshore wind in Maine.

A proposed transmission project to relieve transmission constraints in Maine has received a major boost with the U.S. Department of Energy’s announcement of an up-to $425 million investment in the project, but challenges still remain.

The Western summer reliability outlook is better than in recent years, but shortfalls could arise because of supply chain problems or scarce imports, WECC says.

MISO officials answered questions about the capacity shortfalls and expensive prices in the 2022/23 auction while stakeholders asked for more supply data.

A CAISO market report says high natural gas prices drove a 50% run-up in electricity costs in Q4 2021, hitting the Western Energy Imbalance Market as well.

CAISO's Board of Governors extended controversial wheel-through restrictions for two more years as the ISO works on a long-term fix to transmission constraints.

The West's reliance on imports could prove problematic during summer heat waves or when hydroelectric generation dries up because of drought, WECC said.

The NYISO Business Issues Committee Ok'd tariff revisions related to implementing a revised approach to the current transmission constraint pricing logic.

PJM and other RTOs are seeing a “very dynamic” transmission system as older generation retires and a whole new class of generation comes online.
