It's minus 24 at my house this morning, and here are some pix I snapped of the ISO-NE Real-Time system page.To me, the first one is the most telling: 20,000 MW demand, 243 MW in reserve. That's too little reserve!The rest are more typical winter ISO.Grid running at over $200/MWh.Actually, it has been bouncing up to over $300/MWh, in the five-minute market. I just didn't get a screen shot at the higher levels.And here's the fuel mix: Lots of coal and oil, of course: total of 27%. Renewables hanging in at 6%.And the renewables chart. Wind is actually a reasonable part of it, since this has been windy weather. Wood and refuse dominate, of course. Of course, what is "reasonable"? Wind is 17% of 6% on a day the grid is struggling.Our summer peak is above 20,000 MW, and today is only 19,000. However, in the summer, you can get natural gas to the gas-fired plants.
