Benefits and costs of a utility-ownership business model for residential rooftop solar PV systems

This webinar summarizes key findings from Berkeley Lab’s recently published study, Benefits and costs of a utility-ownership business model for residential rooftop solar photovoltaic systems. The study, published in the journal Nature Energy, evaluates the financial performance of a hypothetical utility-owned residential rooftop solar program, estimating its effects on both utility shareholder earnings and on non-solar customer bills.

New data compilation illustrates the maturity and declining cost of wind energy

We are pleased to announce the release of Lawrence Berkeley National Laboratory’s Wind Energy Technology Data Update: 2020 Edition. The release provides an updated overview of data and trends in land-based wind energy in the U.S., in the form of a briefing slide deck, a data file, and a series of data visualizations.

Berkeley Lab report evaluates utility-owned rooftop solar

The rapid growth of rooftop solar photovoltaic (PV) systems can pose a number of financial challenges for both electric utility shareholders and their customers. One potential pathway to resolving those concerns involves allowing utilities to own and operate rooftop solar systems. However, the financial impacts of this business model are not well understood.

New data tool from Berkeley Lab tracks proposed projects in interconnection queues

new data visualization from Lawrence Berkeley National Laboratory synthesizes data from generation interconnection queues to illustrate trends in proposed power plants across time and regions. The data compilation demonstrates considerable developer interest in solar, wind, natural gas, and standalone storage plants, as well as growing interest in so-called “hybrid” plants that combine multiple generation types and/or storage at the point of interconnection.

System-level performance and degradation of 21 GW-DC of utility-scale PV plants in the United States

This webinar discusses key aspects and findings of this newly published article System-level performance and degradation of 21 GWDC of utility-scale PV plants in the United States in the Journal of Renewable and Sustainable Energy. This webinar describes the analysis sample (411 utility-scale PV projects totaling 21.1 GWDC of capacity that achieved commercial operations in the United States from 2007-2016), the approach taken (a “fixed effects” regression model), and key findings. 

Interest in Hybrid and Co-Located Power Plants Continues to Grow

New data compilation from Berkeley Lab tracks existing and proposed projects

As battery prices fall and wind and solar generation rises, power plant developers are increasingly combining wind and solar projects with on-site batteries, creating “hybrid” power plants. But hybrid or co-located plants have been part of the U.S. electricity mix for decades, with widely ranging configurations that extend beyond pairing a generator with a battery.

New research assesses fleet-wide performance of utility-scale PV in the United States, and how it has changed with age

Berkeley Lab is pleased to announce a new article recently published in the Journal of Renewable and Sustainable Energy, titled “System-Level Performance and Degradation of 21 GWDC of Utility-Scale PV Plants in the United States.” This study finds that first-year performance generally lives up to ex ante expectations, while the rate of performance decline over time depends on factors such as plant vintage, size, location, and configuration.

Impacts of High Variable Renewable Energy Futures on Electric-Sector Decision Making: Demand-Side Effects

Previous work by the Berkeley Lab describes how high shares of variable renewable energy (VRE) such as wind and solar power could change wholesale electricity price dynamics. These include the timing of when electricity is cheap or expensive, locational differences in the cost of electricity, and the degree of regularity or predictability in those costs.
