What is ERCOT capacity?
ERCOT, which serves about 90% of the state, said there would be 91,392 MW of resource capacity available during summer peak demand hours. This includes 473 MW of planned natural gas-fired, utility-scale solar and wind capacity.
What is ERCOT reserve margin?
The reserve margin is the percentage by which forecast seasonal peakload is exceeded by the capacity of resources likely to be available at peak time. Increasing the reserve margin would tend to decrease wholesale power prices.

Does ercot have a capacity market?
Unlike other grid operators, the Electric Reliabiltiy Council of Texas (ERCOT) operates only an energy market to meet customer demand and does not use a capacity market to ensure necessary resources will be available. Instead, the state depends on the promise of higher prices to incentivize generation.
How is ERCOT different from other isos?
Unlike certain other regional power markets, the ERCOT market is not a centrally dispatched power pool, and the ERCOT ISO does not procure energy on behalf of its members other than to maintain the reliable operations of the transmission system.
What type of market is ERCOT?
only wholesale electricity market
The Electric Reliability Council of Texas, or ERCOT, is a nonprofit organization that operates an energy-only wholesale electricity market for 90 percent of the state of Texas. This market design pays generators only for the energy they provide to the grid, with very few exceptions.
How does the ercot market work?
In the ERCOT-administered wholesale markets, ERCOT uses nodal energy prices for resources. Nodal energy prices are location-specific marginal prices based upon resource-specific bids to provide energy. ERCOT selects the least-cost resource that will support reliable operation of the ERCOT grid.
How does the ercot Ordc work?
Instituted in 2014, the ORDC automatically increases the price of power as reserves get tighter. The ORDC adder activates when operating reserves decrease below 6,000 MW and continue to decline, with the maximum price adder applied when reserves drop to 2,000 MW.
Does ERCOT board get paid?
Cramton and several other board members drew an annual salary from ERCOT, too. His was $87,000 in 2019, tax records show. Another departing out-of-state board member, Terry Bulger, a banker who served as finance and audit chair, made $92,600 in 2019.
