Photovoltaic electricity is growing fast in New Hampshire, according to data from the US Energy Information Administration: We went from an estimated annual production of 45,000 megawatt-hours during the first three quarters of 2016 to 78,000 Mwh in the same period of 2017.

That’s a 73 percent rise – woo-hoo! But big percentage increases are easy when you start small. To put its effect on the grid in context: That nine months of solar output – 78,000 Mwh – is roughly the output of Seabrook Station nuclear polant over three full days.

And to put New Hampshire’s accomplishment in solar-PV context: During the same period Massachusetts produced 2,233 Mwh, or 30 times as much. Of course, Massachusetts is a lot bigger than us. But Vermont isn’t – and over that period it generated 233 Mwh, or more than three times as much.

We are photovoltaic laggards.

There’s a lot more solar in the pipeline, including a number of projects that are 10 Mw or larger, as Bob Sanders reported for NHBR recently.
