Faster-than-Expected Data Center Load Growth May Cause Increased Regional Short-term Fossil Fuel Generation and Wholesale Electricity Prices

LCG, March 18, 2026--The EIA released a new "In-depth Analysis" of the potential impact of faster-than-expected near-term growth in data center power demand on power generation and wholesale prices on March 12. The analysis models the lower 48 states through 2027 and compares results to its base case scenario. Key takeaway from this sensitivity analysis is the potential increase in fossil fuels in some regions and potentially a significant increase in wholesale prices in ERCOT.

The Energy Information Administration (EIA) adopts UPLAN for potential integration with its Short Term Energy Outlook

LCG, October 8, 2014 – The office of Energy Information Administration (EIA) of the US Department of Energy has acquired UPLAN Network Power Model for specialized electric modeling. EIA has also acquired the accompanying Plants, Loads, Assets, Transmission and Operations (PLATO) data models for the entire US electric system.

UPLAN Network Power Model (UPLAN-NPM) developed by LCG Consulting of Los Altos, California, is a chronological electric grid model that is used to perform detail transmission, generation and economic analysis. The EIA staff plans to use UPLAN-NPM for scenario analysis, discussion papers and today-in-energy analysis, and to evaluate UPLAN-NPM forecasts for potential future incorporation in the Short Term Energy Outlook for electricity generation modeling.
