LCG, June 23, 2025--The Governor of New York today directed the New York Power Authority (NYPA) to develop and construct an advanced nuclear power plant in upstate New York to deliver zero-emission power that supports a reliable and affordable electric grid. NYPA will lead the effort to develop at least one new nuclear energy facility with a combined capacity of at least one gigawatt (GW) of electricity, either alone or in partnership with private entities. The directive builds on the Governor’s 2025 State of the State to develop nuclear energy plans in New York.

Federal Government uses UPLAN model to examine price volatility in ERCOT
LCG, October 11, 2022--The U.S. Energy Information Administration, or EIA, released its latest supplement to the Short-Term Energy Outlook (STEO) in the Texas market, assessing various possible scenarios using LCG’s UPLAN NPM model, with a special focus on the effects on wholesale power prices and market conditions.
To balance the supply of electricity and power demand, grid operators must make sure that there is an adequate supply to meet demand in an uncertain future. Texas's grid operator, the Electric Reliability Council of Texas (ERCOT), allows the energy component of wholesale prices to increase substantially when the resource reserve is low, called scarcity pricing. This price volatility provides an incentive for new capacity investments.
In the EIA’s report, four scenarios were explored: 1) Normal levels of load and wind generation, 2) High levels of peak electricity load, 3) Low levels of wind generation, and 4) Simultaneous occurrence of high peak load and low wind generation. These scenarios are similar to those ERCOT considers in its Seasonal Assessment of Resource Adequacy.
EIA used UPLAN and LCG’s PLATO database to develop the forecasts for electricity supply. The resultant dataset, including the fuel consumption, the electricity generation and the wholesale electricity price were then fed into EIA’s own model, the U.S. Short-Term Energy Model, to produce the final results.
Among other findings, EIA’s investigation showed pricing is sensitive to the variable cost of generation in the early morning and at the end of the day. When the demand starts to rise during the midday, electricity prices can rise significantly above the marginal costs. Scarcity pricing is more likely when wind generation is low than when the demand is high. And the impact of low wind and high load on prices varies across the ERCOT region.
