Colchester, Vt – Green Mountain Power’s Stafford Hill Solar Farm in Rutland, one of the nation’s first micro-grids powered solely by solar and battery back-up, is now the first in the region to use battery storage to reduce peak power usage, benefiting customers […]

Microgrids Are Coming!

By George Harvey

The Brattleboro, Vermont Energy Committee recently formed an Integrated Energy Systems subcommittee with the purpose of investigating such solutions as microgrids and the technologies that might be used with them. A microgrid is a system that has its own generating and storage capacity, with a potential to operate independently of the […]

Science and Technology:

Solid-state batteries capable of delivering on a 400+ mile range per single charge are a real possibility and possess “great potential” according to Volkswagen’s Chairman of the Board Dr Martin Winterkorn. If such a battery can be economically manufactured, then that would more-or-less turn the industry upside-down. [CleanTechnica]

Science and Technology:

When researchers talk about “islanding,” or isolating, from the grid, they are discussing a fundamental benefit of microgrids, or small systems powered by renewables and energy storage devices. The benefit is that microgrids can disconnect from larger utility grids and continue to provide power locally. [Science Daily]
