While the high load and generation outages followed the pattern of the polar vortex, MISO managed to keep prices stable and maintain better reliability.

FERC has allowed MISO to waive its $1,000/MWh offer cap for the fourth straight winter in response to the extremely cold weather.

Lubbock Power & Light filed testimony with the Texas PUC (PUCT) in support of its proposal to move about 430 MW of load from SPP into ERCOT.

Power prices surged along with demand across much of the U.S. as a blast of Arctic air sent temperatures plunging to record lows.

PJM has a lot on its plate for 2018, including an ongoing effort to change its capacity market structure, the DOE NOPR and gas-electric coordination.

The Dec. 21 FERC order requiring SPP to help fast-start resources set LMPs added one more to-do for the RTO in what is shaping up to be a busy 2018.

ERCOT enters 2018 facing new questions, as the growth in wind energy has begun threatening not only coal but also less efficient natural gas-fired generation.

MISO’s 2018 to-do list includes continuing efforts to expand energy storage participation and extensive software upgrades.

MISO won FERC permission to expand its mitigation measures on narrowly constrained areas to address intense but temporary congestion.

PJM’s initiative to internalize all generator payments moved forward at the MRC when stakeholders endorsed the RTO’s proposal to examine price formation.
