Figure 1: Distribution-scale solar costs more than wholesale power, but it costs less if you fairly value all benefits

“New Record Set for World’s Cheapest Solar.” A headline like this makes for great social media fodder. The downward trend in renewables prices is fantastic—it’s the most important driver for the growth of solar and wind energy.

However, when your business or utility is comparing different energy projects, looking at cost alone is not enough. Even energy projects at very low costs can be “out of the money” if the value created by a project is less than its cost.

DC just proposed a first-of-its-kind regulatory body—and utilities should pay close attention.

Two Washington, D.C. City Council members proposed a remarkable change in utility regulation last week. Mary Cheh and Charles Allen introduced a bill to create a Distributed Energy Resource Authority (DER Authority): a first-of-its-kind regulatory body that would be empowered to undertake traditional utility planning functions, and with a specific mandate to assess any proposed utility grid investment greater than $25 million and open it up to competitive bids.

This valve assembly is the aboveground portion of an injection well, which can be used to dispose of fluid deep in the subsurface. Recent studies show that the cumulative effects from injection in numerous disposal wells can contribute to seismic activity far from the injection sites.

High-volume fluid injection can cumulatively increase underground pore pressure and induce earthquakes in regions unexpectedly far from injection wells, recent Kansas studies show.

Seismologists largely attribute widespread earthquakes in southern Kansas and northern Oklahoma over the past several years to injection of extracted oil field brine deep into Earth’s crust. Recently, however, the frequency of earthquakes has increased significantly in areas of Kansas well beyond the initial high-seismicity zones near injection wells.

Energy Innovation's Michael O'Boyle and Silvio Marcacci outline the barriers to high-penetration wind and solar in the least-cost era

The following is a viewpoint from Michael O'Boyle, electricity policy manager for Energy Innovation, and Silvio Marcacci, communications director for Energy Innovation

Wind and solar are now cheaper than virtually anyone predicted, and renewable technologies have reached an inflection point: Rapid cost declines made renewable energy the cheapest available sources of new electricity, even without subsidies, in 2017.  In many locations across America, building new wind energy projects is cheaper than running existing coal-fired power plants.
