Storage is the Boss for Utility-Scale Microgrid Yielding 70% Renewables

energy storage

A utility-scale microgrid that uses energy storage has slashed the use of diesel fuel and allowed for up to 70 percent renewables to serve a Portuguese Island, Graciosa. The microgrid is made up of a 6-MW, 3.5-MWh battery system from Switzerland-based Leclanché, about 1.5 MW of wind energy, 3 MW of solar and an existing diesel system that … [Read more...]

A Community Microgrid, Some Prosumers and Energy Sharing

energy sharing

A community microgrid, some prosumers and consumers — all with access to backup power from a utility — could form the basis for energy sharing in a community, according to a research report from a Missouri University of Science and Technology researcher. Julia Morgan, a Ph.D student in systems engineering, has developed a model for energy … [Read more...]

PXiSE Aims to Create “Federation of Microgrids” in Australia with DERMS

Federation of Microgrids

Sempra subsidiary PXiSE Energy Solutions plans to create a federation of microgrids to boost renewable energy in remote Australia towns under a new agreement with utility Horizon Power.
