How BESS can replace peaker plants and help clean up NYC5 Apr 2021 21:33
A combination of renewable energy, energy efficiency and energy storage can be used to effectively retire New York City’s entire fleet of more than 6GW of peaker plants by 2030, a new study has found.
New York City’s fossil fuel-fired peaker plants are among the most under-utilised assets on the grid and produce the most expensive electricity, but contribute highly to emissions levels, particularly nitrogen oxides, carbon dioxide and sulfur dioxide, contributing to greenhouse gas levels as well as health risks. Due to the densely populated nature of the city and electricity load constraints, most are sited close to urban centres.
The plants are only called into action during periods of peak demand, hence the name, but they are still paid around US$400 million in capacity payments to be available throughout the year, every year. This means that while electricity from them can be up to 1,300% more expensive than the average cost of electricity in the state, most of New York City’s peaker plants only run for about 5% of the entire year. Similarly, the vast majority are never called into action for more than eight hours at a time and generally for far fewer hours.
In a new study by Strategen Consulting, commissioned by a collection of environmental justice groups called PEAK Coalition, around 5.6GW of rooftop solar, 3GW of offshore wind, 5,400GWh of energy efficiency measures and 4,200MW of energy storage could fulfil the role of the city’s entire fleet by 2030...
