Energy Efficiency

Yesterday, energy storage company Saft said it delivered and installed a turnkey Energy Storage System to Bermuda Electric Light Company (BELCO). The system provides up to 10 MW power for spinning reserves and frequency response to maintain grid stability and has a storage capacity of 5.5MWh, said the company. The official ribbon-cutting ceremony was held on May 16.

Southeastern utilities have made headlines recently with plans to incorporate battery storage at solar installations across their service territories (see Florida Power & Light and Duke Energy). It turns out that the communities they serve could greatly benefit from installing solar+storage as well.  

Renewable Energy Portfolio Standards require the utilities to generate or procure a minimal percentage of energy in their portfolios from renewables energy as defined by the eligible technologies in each statute, namely solar, wind, hydro, geothermal, biomass, and storage. The first stage of the policy occurred in the early 2000s as states began to enact the policies into law with goals of around 20%. But today, we are currently in a new era where state legislatures and Green New Deal advocates are debating whether or not to increase the nominal requirements - the percentages of the energy portfolios to come from renewables -  to either 50% or 100% within the next 15 or so years. In terms of the actual energy that has to be produced to meet the standards, the targets are significantly increasing.  

For the third year in a row, the U.S. solar industry installed double-digit gigawatts (GW) of solar PV capacity, with 10.6 GW coming online in 2018, according to the latest statistics from Wood Mackenzie Power & Renewables and the Solar Energy Industries Association (SEIA).

Next week thousands of utility executives and energy industry stakeholders will flock to New Orleans to participate in DistribuTECH 2019 — a show predominantly for distribution utilities — and for the first time, a handful of solar equipment companies will be among the hundreds of exhibitors in the exhibit hall.
