Distributed Energy Resources 101: Required Reading for a Modern Grid


Distributed_Solar_Power-781012-edited-3.jpg

Keeping up with the influx of new information on distributed energy resources (DERs) can be daunting. DERs are physical and virtual assets that are deployed across the distribution grid, typically close to load, and usually behind the meter, which can be used individually or in aggregate to provide value to the grid, individual customers, or both. A particular industry interest seems to be centered on DERs — such as solar, storage, energy efficiency, and demand management — that can be aggregated to provide services to the electric grid.

Since the U.S. Department of Energy released the 2017 U.S. Energy and Employment Report last month, several reports have come out from industry trade groups, and, though they focus on different things, there’s one overarching conclusion. As the Sustainable Energy in America Factbook says, there’s a new normal in America, and that normal is advanced energy. AEE members are making it so, from energy efficiency and big data to making solar + storage available to everyone.

Today, the Business Council for Sustainable Energy (BCSE) and Bloomberg New Energy Finance (BNEF) released their fifth annual “Sustainable Energy in America Factbook.” What’s the big theme that emerges from the book this year? Advanced energy is now the new normal, adding gigawatts of new renewable energy generation capacity and improving energy productivity to meet the demands of a growing economy.

THIS IS ADVANCED ENERGY: Geothermal Power

Posted by Caitlin Marquis on Feb 7, 2017 5:36:27 PM

This post is one in a series featuring the complete slate of advanced energy technologies outlined in the report This Is Advanced Energy

Geothermal power taps into the high-temperature hydrothermal resources of the earth to generate electricity. There are three main types of geothermal technologies: dry steam, ash steam, and binary. Dry steam plants withdraw steam directly to drive a turbine. Flash steam, the most common geothermal technology used today, pumps high-temperature geothermal fluids at high pressure into a low-pressure tank, which causes the fluids to vaporize (or “ ash”) so they can be used to drive a turbine. A binary cycle is a closed-loop process where low-temperature geothermal fluids are used to heat a second fluid with a low boiling point (e.g., refrigerants or propane), which in turn drives a turbine. Binary cycle power plants are expected to dominate future markets because low-temperature resources are more plentiful and generally easier to access.

Not too long ago, the media was heralding a possible end to the current era of utilities, calling them “dinosaurs” and debating the speed with which the “utility death spiral” would overtake them. Over the past few years, it’s become clear that utilities aren’t going anywhere anytime soon, but the utility business model is undergoing significant and permanent changes – driven by advanced energy. On that point, this week we saw a lot of thinking, and doing, in the news.
