Vermont has a Standard Offer, SO, program that uses federal, state and other subsidies and feed-in tariffs, c/kWh, in excess of wholesale prices to increase the build-out renewable energy systems. Most of those systems are large-scale, field-mounted solar systems. The Public Utilities Commission, PUC, oversees the program and issues a Certificate of Public Good for each project. This article examines the economics of a large-scale solar system.

Based on the plan of eliminating fossil fuel plants (they emit CO2 and particulates) and nuclear fuel plants (they are alleged to be dangerous) by 2050, the existing gas, nuclear, coal and oil generating plants would be decommissioned and no new ones would be built.
This would require huge build-outs of wind, solar, and storage systems, and increased electricity supply via external ties to adjacent grids. There is no way one can close down nuclear, oil, gas and coal plants,…Continue
Matt Cota, executive director of the Vermont Fuel Dealers Association testified: “Cold-climate heat pumps are inadequate during the colder days in winter. Many households with heat pumps found they could not adequately heat their houses.

- Battery systems could prove…Continue
