MISO is defending its methods for validating utility load forecasts after Dynegy charged that Ameren miscalculated its summer peak load forecast.

State regulators proved reluctant to be pinned down on predictions about the future of the grid at the annual meeting of the Organization of MISO States.

MISO proposed to rely on its own load forecasting to support long-term transmission planning, instead of a combination of forecasts provided by LSEs.

After criticizing Ameren Illinois for miscalculating its summer peak load forecast, Dynegy called on MISO to develop a new process for verifying forecasts.

FERC rejected SPP’s request to remove its day-ahead must-offer requirement, saying the RTO had not provided “sufficient support” for the Tariff revisions.

The difference between the reserve measurements in PJM’s SCED engine and its emergency management system (EMS) has been shrinking.

EIM market participants voiced concerns about fluctuating load forecasts that make it harder to pass resource sufficiency tests.

PJM told stakeholders at the Operating Committee meeting that late-day storms in the RTO in July resulted in overestimated load forecasting last month.

PPL is maintaining a flat demand outlook for its U.S. service territories through 2020, executives said during the company's second-quarter earnings call.

The PJM Planning Committee approved revisions to the rules for the Regional Transmission Expansion Plan, agreeing to extend the cycle to 18 months.
