A microgrid is composed of a small network of power generators for sharing electricity and heat on a local, community level. Think of it like peer-to-peer file-sharing technologies, such as BitTorrents, where demand is split up and shared around the network of "users". It supposedly can be integrated for substantial savings to the pocketbook and to the environment with no major changes to lifestyles.



Distributes the power so that it is not so vulnerable (in contrast to a central power company)

Can easily integrate alternative energy production, such as wind or solar

Reduces line transmission losses

Heat from energy generation can be recouped into local uses for heating water or warming buildings in cold weather.

Microgrids as Peer-to-Peer Energy - Overview of the concept. (BBC Sept. 25, 2005)

Small is beautiful – scientist proposes new efficient and eco-friendly power plants - Power plants of the future may be designed to provide electricity solely for an individual housing estate, village, factory or college. That’s the prediction of University of Southampton engineer Dr Tom Markvart. (PhysOrg Sept. 26, 2005)

Alternative energy research center fuels up for the future - NextEnergy has a separate structure that it calls a microgrid power pavilion, which is used for testing engines that burn different fuels as well as for heating, cooling and powering the main building. (Detroit News Aug. 26, 2005)

Google News > Microgrid


Green Alliance - Has been "pushing for micropower generation technologies, such as micro-CHP (combined heat and power) boilers mini-wind turbines and photovoltaic (PV) solar arrays. Micro-CHP units work by turning heat which would normally escape through flues into electricity. Homeowners then sell any surplus electricity back to the national grid." (ref)
