Lots of articles and headlines in the news in the last few days about the possibility of region wide black outs and brown outs this winter (and upcoming winters). This made the regional news recently, but the regional grid operator has been predicting it for several years. Faulty comparisons are being made to the Texas issue and California Issue last winter. IMO there are major differences. The New England grid has been playing Jenga for several years where large base load non natural gas plants like Nukes and Coal have been shutting down and if they are partially replaced, they are being replaced with natural gas generation. Unfortunately the New England gas supply has been constrained due to inadequate supply and political reasons. When it gets really cold, the gas grid has to decide whether to send gas to homes and business for heating or send it to gas plants for generating power.

The quick summary is as long as we have warm winter in the region and the large baseload natural gas plants can run, not an issue. If on the other hand it is a long cold winter, the grid will be short at times and ISO NE will have to start executing load planning actions that starts out with voluntary load reductions but could ramp up to rotating brown outs and eventually black outs. Loose Seabrook nuclear power plant during those periods and its near guarantee there will need to be load reduction events.
LNG was being used to add gas to the gas supply grid and it used to be readily available. It is a worldwide commodity and China, Europe and Japan are all desperate for it, It is likely it will not factor in to reinforce the gas supply. There is no quick fix, the grid either needs to get a bunch of transmission lines to Hydro Quebec or new non natural gas generation needs to be added. Renewables really do not factor in on this as they are not reliable enough for worst case planning. Add in storage like Hydro Quebec and it then becomes more of a factor. Note Europe is doing this with pumped hydro in Norway Finland and Scotland. They have the transmission lines that New England does not. Note these is some extra gas available through the PNGTS natural gas pipeline from Quebec but no one wants to pay for the upgrade.
Brown outs are not optional, if the load does not drop, it can turn into a blackout. Brown outs can damage marginal equipment, when the voltage goes down the amperage goes up.
