New York Announces Energy Storage Roadmap to Add 1,500 Megawatts by 2025 to Combat Climate Change

LCG, June 22, 2018--The Governor of New York Thursday announced his New York Energy Storage Roadmap that targets 1,500 MW of energy storage by 2025 to combat climate change. New York State currently has approximately 60 MW of advanced energy storage capacity deployed and another 500 MW in development. There is also 1,400 MW of traditional pumped storage hydro capacity.

Impacts of High Variable Renewable Energy Futures on Wholesale Electricity Prices, and on Electric-Sector Decision Making

May 23, 2018 -- Lawrence Berkeley Lab partnered with LCG Consulting to develop a large number of variable renewable energy (VRE) scenarios to derive future generator portfolios and hourly price and emissions series. The main objective of this exercise is to offer policymakers, utilities and grid authorities a long-range view of how current choices could impact their future ability to cope with changes in the electric sector.

In particular, simulations address generation mix, wholesale and ancillary service prices, and carbon emissions across SPP, NYISO, CAISO, and ERCOT in 2030. The modeling effort and the underlying simulations were led by an LCG expert team and conducted with LCG’s proprietary models including the long-term least-cost planning program, Gen-X, the integrated G&T market model, UPLAN-NPM, and the regional PLATO data models.

The study found a general decrease in average annual hourly wholesale energy prices with more VRE penetration, increased price volatility and frequency of very low-priced hours, and changing diurnal price patterns. Ancillary service prices rise substantially and peak net-load hours with high capacity value are shifted increasingly into the evening, particularly for high solar futures. A significant decrease in non VRE generation and a modest decrease of firm capacity need were observed for high VRE future. Figure below shows the mean diurnal (24h) energy price profiles by scenario and region, averaged over all weekdays.

The diurnal price profiles display the infamous duck curve in all regions for high solar case. The overall electricity prices for all VRE scenarios show a decline across all regions by $5 - $16/MWh with strong total price decline in NYISO, CAISO, and SPP for the solar case while ERCOT has the largest price reduction in the wind case. For the high VRE cases, the study observed substantial increase in low price hours. The annual share of low price hours where the prices are below $5/MWh varies from region to region from 2.5% to 19% for all hours of the year. These low price hours offer an opportunity for hybrid renewables and storage developers such as CAES, batteries, and load shifting programs to optimize their asset portfolios.

The changes in the diurnal energy price profile, high ancillary service prices, and increased volatility may offer energy industry participants a new perspective for their future planning under alternative scenario. Hopefully, the study brings into focus how the current choices could impact their future ability to cope with changes in the electric sector.
