Just to add a little clarification here. When the energy markets were deregulated, Eversource (then Northeast Utilities as a delivery company) was separated from any generation assets they owned. The generation rate paid on your eversource bill is a direct result of Eversource going out on the wholesale market and "buying" power from generators and then passing the cost on to the users. Eversource delivers you the electricity, they don't generate it. They do this through negotiating different contracts with different supply companies. This winter the massive increase in natural gas and fossil fuel prices is what's driving the increase in electricity generation. It pretty much happens every winter, although its happening on a much larger scale now.

If we want to solve this as a state, we badly need shift away from our huge reliance on natural gas which is somewhere around 55% of our current supply. The ONLY way to do this in a cost effective manner is to bring more nuclear online in CT. Less gas going to electricity generation will also have the dual effect of lowering home heating costs for gas users.

More renewables can help in the long run, and should be a bigger part of the diversification as well, but you can't solve this problem without nuclear.
