As the transition to clean energy accelerates, developers are rushing to get new generation projects connected to the grid. This has caused a traffic jam on the on-ramps, as projects clog up the “interconnection queues,” where developers apply to grid managers for access. Berkeley Lab’s Electricity Markets & Policy Department has been tracking the phenomenon, and analyzing ways that the... Read more

Information access, public participation, and fair decision-making are key to wind energy’s “procedural justice” Expanding wind energy deployment to meet climate and policy goals requires willing communities to host wind projects. Previous research finds that perceptions of the fairness of a wind project’s planning process strongly influences attitudes among host communities. Yet, few... Read more

Subsidies for low-income solar are reaching the right households and increasing adoption in disadvantaged communities. Many states have offered subsidies to promote rooftop solar adoption. Most of these subsidies have phased out over time, partly under the assumption that subsidies become less necessary as solar prices decline. However, even though solar prices have declined significantly,... Read more

Berkeley Lab is pleased to announce the release of a new report, titled “Plant-level performance and degradation of 31 GWDC of utility-scale PV in the United States.” This report updates an earlier analysis first published two years ago, with the benefit of a 50% larger sample than in the original study, as well as two additional years of performance to evaluate. Specifically, we assess the... Read more

New Berkeley Lab study provides insights into wind turbine shadow flicker perception and annoyance The moving shadows caused by wind turbines, referred to as “shadow flicker” (SF) (see figure 1), are known to generate annoyance in some people. However, the relationship between the amount of SF exposure and the annoyance it causes is poorly understood. A better understanding of the magnitude,... Read more

An unexpectedly cloudy day can cause solar generation to dip below expectations, and in consequence, other generators will need to compensate with additional output. One possibility is that fast acting gas combustion turbines would fill this generation gap, and while this is suitable solution from a reliability standpoint, a more fuel efficient combined cycle generator might have been able to...
