EIA Publishes Regional Electricity Supply and Pricing Forecasts Using UPLAN Model

LCG, August 13, 2019--The U.S. Energy Information Administration (EIA) announced that it is revising the presentation and modeling of its forecasts for electricity supply and market hub pricing to better reflect current electricity markets and system operations in the U.S. Beginning with the August 2019 Short-Term Energy Outlook (STEO), the new forecasting approach models electricity markets using the UPLAN production cost optimization software developed by LCG Consulting. EIA uses the solution results provided by this proprietary model to develop the STEO forecasts of monthly electricity generation, fuel consumption, and wholesale prices.

Dominion Energy Virginia Pursues 500 MW of Renewable Projects

LCG, August 8, 2019--Dominion Energy Virginia announced Monday that it is seeking bids for up to 500 MW of renewable capacity in both 2021 and 2022 to increase its clean energy resources. Dominion Energy stated that it is committed to having 3,000 MW of solar and wind in operation or under development in Virginia by 2022. This near-term step is part of an ultimate company commitment to reduce carbon emissions by 80 percent by 2050 across the 18 states it serves.

Wind Power Output in ERCOT Exceeds 15,000 MW

LCG, November 30, 2016--A new wind power record of over 15,000 MW was achieved at 12:35 p.m. on November 27 in Texas for the Electric Reliability Council of Texas (ERCOT) region. The region used 15,033 MW of electricity from wind farms, which accounted for approximately 45 percent of the total demand for electric power at the time. Wind farms in West and North Texas delivered more than 8,800 MW, the South region provided almost 3,800 MW, and approximately 2,300 MW came from the Panhandle region.

The portion of load served by wind on November 27 ranged from about 35 percent to more than 46 percent, averaging nearly 41 percent throughout the day. The current record for percentage of load served is 48.28 percent and was set earlier this year on March 23.

ERCOT's Senior Director of System Operations stated, "We saw high wind output throughout the day, ranging from just over 10,000 MW during the late night hours to this peak output during the noon hour. Over the years, ERCOT has taken a number of steps, such as improving renewable generation forecasts, to allow us to operate the grid reliably on days like this."

There is over 17,000 MW of installed wind generation capacity serving the ERCOT system today, and that total is expected to exceed 19,000 MW by year-end.

In 2015, wind generation provided 11.7 percent of the energy used in the ERCOT region. As of the end of October, wind had served 14.7 percent of the region???s energy needs in 2016.
