Pennsylvania, the epicenter of the nation’s fracking business, isn’t precisely a vanguard in clear vitality improvement. It ranks squarely in the midst of U.S. states by way of photo voltaic deployment, with about 540 megawatts of photo voltaic put in as of mid-2020, lower than half a % of its complete era capability, in accordance with the Photo voltaic Vitality Industries Affiliation.
About four-fifths of that’s distributed photo voltaic of lower than 5 megawatts, the utmost system dimension eligible for internet metering beneath state legislation. Of that, about 180 megawatts consist of residential rooftop photo voltaic methods lower than 15 kilowatts, in accordance with information from the Pennsylvania Public Utilities Fee.
That’s an honest quantity of rooftop photo voltaic, however definitely not sufficient to trigger the form of voltage fluctuations, two-way energy flows or “duck curve” vitality supply-demand imbalances which can be beginning to disrupt energy grids in Hawaii, California and different solar-heavy states.
However for PPL Electrical Utilities, which serves about 1.four million prospects in jap Pennsylvania, the truth that it solely has a number of thousand rooftop PV methods on its system so far — in comparison with greater than one million in California — isn’t a great purpose to not begin to plan forward for managing its future progress.
