There are enough power plants, power lines and systems in place to provide all the electricity that
However, ISO-NE said in its annual pre-winter assessment, as many as 4,500 megawatts of electricity comes from plants that burn natural gas are “at risk of not being able to get fuel when needed,” because so much gas is burned for heat in the winter.
About one-ninth of New England’s electricity demand usually comes from within
Despite the projected ample supply, ratepayers usually see higher rates in the winter because the cost of buying fuel tends to rise. Eversource’s energy rate, which changes every six months, is 19 percent higher for the winter period through February than it was in the previous six months.
ISO-NE said that as a result of these problems it has instituted new market and system operations. One will forecast the region’s available energy supplies for the following 21 days, and the other will provide a market mechanism designed to help ensure that limited fuel supplies are used when they are most valuable for system reliability and cost effectiveness.
This also marks the first winter under new pay-for-performance-capacity rules, which went into effect
Coping with winter extremes is made easier because total energy consumption, as well as peak demand, have remained flat in
As for solar power, ISO-NE notes that daily electricity demand usually hits its peak in winter after the sun has set, reducing the value of photovoltaic systems for coping with emergency situations.
The all-time winter peak demand in
