How Massachusetts Compensates Battery Storage Owners for Energy Efficiency: Report

energy efficiency

When most people think of energy efficiency, they think of using fewer electrons. But the Clean Energy Group has an expanded definition — to shift energy usage from high peaks to low demand times. And it says that battery storage is the important new technology to allow this. The Clean Energy Group, supported by the Barr Foundation and the … [Read more...]

Microgrids Restore Water, Wastewater Services for Isolated Puerto Rico Communities

microgrids

New water and wastewater systems powered by solar plus storage microgrids are reviving life and livelihoods in remote areas of Puerto Rico still struggling to recover from 2017's Hurricane Maria. In hard-to-reach areas of Puerto Rico where grid power has only recently been restored, six microgrid-powered pumping systems are now up and … [Read more...]

Goodbye to Arguments Against Renewables? New Studies Find them as Reliable and Cheap as Fossils

energy-as-a-service

Can renewables cost less than fossil fuel generation? And are they as reliable? It appears so, especially when they are coupled with a suite of distributed energy resources (DERs), such as virtual power plants and demand response. New reports by Energy Innovation Policy and Technology and the Rocky Mountain Institute (RMI) lay out the … [Read more...]

Economics is Driving the Growth of Distributed Energy Resources in Texas

distributed energy

Texas was among those states in the 1990s to restructure its retail electricity market, which gave business and residential consumers the option to choose a power supplier. Today, that type of innovation is expanding to give those users more dynamic options — the ability to generate their own electricity with distributed energy. The Texas … [Read more...]

Medford, Massachusetts is moving forward with a microgrid designed to improve resilience for its public works department and reduce the city’s electric demand charges. The city this week selected solar installer Solect Energy to engineer, procure, install, and service the grid-connected microgrid. The Medford microgrid is being built … [Read more...]

Maine Lawmakers Revive Microgrid Bill as New Governor Creates a Pro-Green Climate

microgrids

Microgrids that regulators determine “serve the public interest” are back in play in Maine this year as lawmakers try to pass a bill that fell short a year ago. Legislators passed a bipartisan bill last year more clearly defining how microgrids could be created, but former Republican Gov. Paul LePage vetoed it. Newly elected Gov. Janet Mills … [Read more...]

New AC-DC Mobile Microgrid Holds Promise of More Efficient Power Distribution

mobile microgrids

A team at the University of Calgary plans to build a mobile microgrid that promises to improve the simultaneous distribution and management of both alternating current (AC) and direct current (DC) electricity. Three university professors are leveraging proprietary AC-DC power conversion and energy management technology to build and operate a … [Read more...]

Move Over, Lithium Ion: Thermal Energy Storage Finds a Niche

thermal storage

Thermal storage is gaining ground in refrigeration applications, providing demand management for one of utilities’ most energy-intensive industries. Industrial refrigeration consumes more energy per cubic foot than any other utility load, said Collin Coker, vice president, sales and marketing, Viking Cold Solutions. Thermal energy storage … [Read more...]
