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.  

In a June 5 response to FERC, MISO defended its plan to bar renewable energy from supplying ramping reserves.

FERC last week told MISO it must provide more details around its plan to exclude wind and solar generation from supplying ramping service.

A WECC study found that the West needs emerging technologies capable of replicating the performance of gas plants to reach 100% clean energy by 2040.

SPP’s MMU is “strongly” recommending that TCRs' funding shortfall be considered a high-priority item, according to its latest quarterly market reports.

SPP’s MMU released its quarterly reports for its RTO and WEIS markets, saying it is evaluating rule changes in the latter to address limited ramp offerings.

MISO staff said the footprint is in for more extreme ramping events after a late April drop in wind output. 

A NARUC report says California will need to use more advanced planning methods to ensure resource adequacy with an ever-growing reliance on renewables.

FERC accepted SPP Tariff revisions implementing recommendations from the RTO’s stakeholders on fast-start resources and ramping products.
