Bill Savings vs. Backup Power: Evaluating Operational Tradeoffs for Home Solar+Storage Systems

Study shows that, in most circumstances, customers should maintain low reserves, prioritizing bill savings over backup power Home battery storage paired with solar photovoltaic (PV) systems can reduce utility bills under certain rate structures while also providing backup power during power interruptions. For power interruptions that come with some warning … [continued]

2023 Was Another Big Year for Newly Installed & Proposed Hybrid Power Plants, Even with…

Newly released data compilation from Berkeley Lab tracks operational and proposed plants Improving battery technology and the growth of variable renewable generation are driving a surge of interest in “hybrid” power plants that combine, for example, utility-scale wind and/or solar generating capacity with co-located batteries. A newly released briefing from … [continued]

Updated Report & Data Illustrate Distributed Solar Pricing & Design Trends

We are pleased to announce the release of the latest edition of Berkeley Lab’s Tracking the Sun annual report, describing trends for distributed solar photovoltaic (PV) systems in the United States, including the growing contingent of distributed solar-plus-storage systems. The report is based on data from roughly 3.7 million systems installed nationally … [continued]

Report Highlights Advancements in Wind Technology & Supply Chains

Though 2023 was a relatively slow year for new wind power deployment in the United States, the industry continues to see growth, solid performance, expanding supply chains, and attractive prices, according to a report prepared for the U.S. Department of Energy (DOE) by Lawrence Berkeley National Laboratory (Berkeley Lab). With … [continued]

Utility-Scale Developers Seek Input From Renewable Energy Host Communities, But Experience Challenges Implementing Community Engagement

Berkeley Lab study reveals how industry engages with energy host communities when developing large wind and solar projects. The increasing deployment of utility-scale wind and solar energy across the US highlights debates about the appropriate role for the public in siting and permitting decisions. Important to these discussions is a … [continued]

Home & Utility Upgrades to Support Electrification & Clean Local Resources

Advances in electric appliances, electric vehicles (EVs), rooftop solar and energy storage — plus incentives from utilities and governments — are attracting growing consumer interest in these technologies. Consumer investments may include upgrades for electric service panels, especially when installing multiple electrification measures in older homes (see photo). In some … [continued]
