MISO’s Independent Market Monitor said ramping needs north of 10 GW are becoming increasingly common and MISO should expect challenges ahead as its solar fleet expands.

A new study from the Northeast Power Coordinating Council outlines some of the major risks that reliance on natural gas generation poses for the New England power system.

MISO expects its in-service solar capacity to grow to 12 GW by the end of winter, a 50% increase over its existing fleet.

SPP’s REAL Team approved base planning reserve margins and a sufficiency valuation curve, codifying months of work.

MISO said a riskier operating environment means it needs a more nuanced approach to its regulation reserve requirements.

CAISO maintained normal grid operations during the Oct. 14 solar eclipse, with swings in solar production that were more muted than models based on clear-sky conditions.

Clean energy groups in MISO have told FERC it should rethink its support of a ban on renewable energy in MISO’s ancillary service market because the commission didn’t consider hybrid resources.

Sharp growth in California solar resources means the Oct. 14 annular eclipse should have even greater impact than 2017's total eclipses.

CAISO issued its first energy emergency alert of the summer after falling short on ramping capacity as solar output rolled off its system.
