Solar Firm Co-Founder Sees Rising Clout of the Energy "Prosumer"
Speaking engagement hosted by the San Diego Renewable Energy Society and Global Energy Network Institute (GENI) highlights the roles that Community Solar, Community Choice Energy, Peer-to-Peer Solar and the Expansion of Regional and Global Energy Grids could play in meeting future energy needs.

San Diego, CA – May 12, 2016 — The next 10 years are going to bring a host of new energy choices and a lot more market clout for so-called energy “prosumers” -- utility customers who consume energy but also produce it, using their own rooftop solar energy systems -- according to Stellar Solar founding partner, Michael Powers.

In addition to the impressive surge of new solar energy installations in the U.S. – which topped 1 million earlier this month – Powers cited four growing energy trends which are literally putting more power into the hands of solar energy customers everywhere including: 1) community solar; 2) Community Choice Energy or CCE; 3) new progress in peer-to-peer solar energy transactions; and 4) the expansion of regional and even global energy grids, which can move renewable power longer distances to new markets.

“The disadvantage of renewable energy has always been its intermittent nature,” Powers explained. “Driven by the sun, solar energy provides more power than you need in the middle of the day and no power at night. It’s ‘non-dispatchable’ – you can’t turn it up and down to match customer demands from one hour to the next.” In order to take full advantage of solar energy’s new widespread popularity, Powers said, there is a need for more flexible markets and more robust transmission systems to move renewable energy to where it is needed. As the pool of solar owners grows, he said, these important market trends are beginning to emerge.

Community solar allows groups of people to invest in large, shared solar arrays and apply some credits to their power bill; in this way, apartment-dwellers and lower-income groups can gain access to affordable solar power. Experts are saying that 2016 could be community solar’s “breakout year.”

Community Choice Energy (or CCE and formerly known as Community Choice Aggregation) is a growing trend in California and other states which allows cities and counties to directly purchase energy on behalf of their citizens – usually including a higher percentage of renewable energy – and relegates utilities to simply transmitting and distributing this cleaner power. Marin and Sonoma Counties have had CCE programs for over 2 years now, with Lancaster signing on last year and San Francisco just launched their own CCE program on May 1, called “CleanPowerSF.”

Even more exciting, Powers said, were recent successful tests of a “peer-to-peer” solar energy trading system in Brooklyn which allows homes on one side of the street to harvest solar energy and sell it to homes on the other side of the street through a trading system which is independent from the utility and uses computer software called “blockchain” to keep track of the monetary value of the trades. “If successful, this could be the 'Uber' of solar energy,” Powers said, “allowing a solar owner in one time zone to ‘deposit’ solar energy into the system and another one miles away to make an ‘energy withdrawal’ and the computers will simply keep track of the money.”

This practice could someday extend to the global level, Powers pointed out, thanks to the plans of State Grid Corp., China’s largest utility, to build a global energy grid over the next 20 years, a project which will take $15-30 trillion and the participation of multiple regional power grid operators on multiple continents. Plans were announced in Beijing and so far, countries including South Korea, Japan and Russia have signed on as partners in developing a pan-Asian energy supergrid to extend as far south as the Phillipines.

Quoting experts such as author Jeremy Rifkin, IEEE senior fellow Clark Gellings and others, Powers said these four developments are all part of the “digital disruption” that has already impacted industries like publishing, entertainment, telecommunications and transportation. “The electric utility industry is simply the next one to be re-invented,” Powers said, “but the impacts of this change are going to be profound and long-lasting -- because everything we know runs on energy. When you lower the cost of energy, you lower the cost of everything.”
