Energy Storage Plus Solar:

Building the New Utility Paradigm

A Presentation on the Progress and Potential by

Geoff Sparrow, P.E., Director of Engineering at ReVision Energy 


Elon Musk just offered to rebuild the Puerto Rico energy system with solar plus storage. California and Massachusetts are leading the nation and the world by accelerating the integration of hundreds of megawatts of energy storage onto the grid. The recent weather catastrophes in Texas, Florida and Puerto Rico are increasing calls for a more resilient grid architecture including microgrids and solar plus storage.  The introduction of GM’s Bolt and Tesla’s Model 3 are significantly increasing battery pack production volumes and reducing battery costs.  Utilities around the country are scaling back their net metering programs, creating greater interest in consumers using storage to keep their electrons home.  The advent of low cost storage coupled with low cost solar is creating a new utility paradigm.


ReVision Energy, a Clean Energy Transition Company, continues to lead the solar-plus-storage revolution, with 50 completed energy storage projects among its more than 7,000 solar projects installed in ME, NH and MA since 2003. Principal applications historically were off-grid applications with backup power applications taking the lion’s share today. Developing markets include customers in Hawaii and Nevada which can’t afford to export excess solar to the grid, and customer encouraged by utilities to store excess production in high solar penetration markets. 


Join us at the BASEA Forum, Thursday, October 12 to learn about how improvements in solar and battery economics are fundamentally changing the future of energy.

BASEA is looking for additional ways to help create a more sustainable energy future.

Please spend some time thinking about this question, and send your suggestions in to us.


Also, if you are interested in working with this group, please let us know. Send comments or questions to

  • BASEA is no longer a chapter of the Northeast Sustainable Energy Association (NESEA) but supports it's mission. Links to NESEA and other regional, national and international solar organizations can be found on the BASEA Links page.


BASEA's Mission

The Boston Area Solar Energy Association is convinced that New England's primary dependence on non-renewable energy sources is costly to our environmental, social, economic and political systems.

Therefore, we foster the design and use of solar and sustainable energy technologies through education, advocacy and the demonstration of practical, cost effective techniques.

It is our goal to promote Renewable Energy for a Sustainable Future.

Please remember that your donations support BASEA.
