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.

Fires, Heat and Humidity Trigger Power Curtailment

LCG, Sept. 14, 2000Two wildfires burning near transmission line, a disappearing could cover that let in the sun and high humidity in the southern part of the state combined yesterday afternoon to cause the California Independent System Operator to declare a stage two electrical emergency and begin the process of curtailing power deliveries to large customers with interruptible contracts.

Yesterday's power demand in the state had been forecast to peak around 4:00 p.m. at 41,500 megawatts, but chances are it went higher because it was a hot, muggy day the kind that air-conditioners are made for. Making matters worse, a fire near Castaic, just north of Los Angeles, threatened transmission lines, making it harder to get power to where it was needed most.

Another fire, in the high Sierras east of Fresno, cut access to power that Cal-ISO was depending on to help maintain reliability on California's overloaded system.

Cal-ISO directed SoCal Edison to reduce its electrical load by 862 megawatts. To achieve this load reduction, the company is required to activate its voluntary load curtailment program, under which large industrial, commercial, and agricultural customers, as well as customers on SoCal Edison's air conditioner cycling program, agreed to have their power temporarily interrupted in exchange for reduced rates.

The curtailment measures are aimed at avoiding a stage three electric emergency, under which utilities would be directed to shed load through necessitating involuntary rolling, or rotating, outages for blocks of customers across their service areas until sufficient reserve levels are achieved.

"By all of us sticking together and cutting back power use as much as possible, we can get through this difficult period and possibly avoid a stage three emergency," Pam Bass, SoCal Edison's senior vice president for customer service, said.
