When utilities and regional grid operators plan electricity systems, they estimate the system value of various types of resources. Performance assessments verify whether the expected grid services are actually provided.
A 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.
Shows that historical drivers of levelized costs are multifaceted, go well beyond capital costs
We are pleased to announce the publication of a new article in the journal Applied Energy focused on historical trends in the cost and value of land-based wind energy.
We are pleased to announce the release of a new report from Berkeley Lab identifying energy efficiency (EE) and demand response (DR) attributes, utility system conditions, and technological factors that are likely to drive interactions between EE and DR.
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 vinta
Supersized wind turbines could deliver $4-5/MWh more in grid benefits than today’s turbine technology, in addition to any direct-cost advantages
Study supports need to expand the design space to focus not only on direct-cost minimization, but also on the underlying value of wind to the electricity system
New study finds solar PV permitting timelines are getting shorter, but customers still face significant uncertainty
Local permitting timelines for rooftop solar systems are getting shorter but remain highly variable, according to a new Berkeley Lab study published in the journal Energy Policy. Most PV permitting processes take fewer than 2 months from permit application to a passed inspection, but some customers face substantially longer timelines. The differences in permitting authority experience and policies explain some of this variation.
New study finds increase in expected useful life and decrease in operating expenses over time for utility-scale PV
Solar professionals report that the assumed useful life of PV projects now exceeds 30 years in most cases, with OpEx dropping by 50% over the last decade.
Avoided energy and capacity costs are the primary yardstick utilities use to determine which energy efficiency programs are cost-effective for their customers. But sometimes "non-energy impacts" — not commonly recognized as directly associated with energy generation, transmission and distribution — represent substantial benefits, such as improving comfort, air quality and public health.
Although AWEA CLEANPOWER has been cancelled this year, much of the education content will be presented via webinars. Four Berkeley Lab Electricity Markets & Policy experts will be presenting sessions on topics spanning the wind industry in the coming weeks.
Wind plant performance declines due to plant age in the United States can be partially managed and is influenced by policy, according to a recent study from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).
A new study by Lawrence Berkeley National Laboratory (Berkeley Lab) estimates that utility efficiency programs for natural gas achieved energy savings at an average cost to program administrators of 40 cents per therm from 2012 to 2017.
Two New Reports Highlight Actions State and Local Governments Can Take to Increase Electricity System Flexibility
Growth in peak demand, higher levels of wind and solar generation, and transportation electrification are raising new challenges for electricity systems. Buildings are a source of demand flexibility that can help meet these challenges cost-effectively.
New article explores the advantages, disadvantages, and development trends of generator-plus-battery power plants
As battery prices continue to fall and the penetration of variable wind and solar generation rises, power plant developers are increasingly combining wind and solar projects with on-site batteries, creating “hybrid” power plants.
A new report by Lawrence Berkeley National Laboratory highlights income trends among residential rooftop solar adopters.
Biennial Data Compilation Identifies Changes in Markets and Power System Operations as Renewables Are Integrated onto the Grid
The share of variable renewable energy (VRE)—mainly solar and wind—generation on U.S. regional power systems more than doubled on average from 2012 to 2018, according to the newly released 2018 Renewable Energy Grid Integration Data Book.
Webinar announcement: Explore the LCOE and market value benefits of wind turbines with larger rotors and taller towers
At 1:00 PM EST on Wednesday, March 4, please join researchers from the Lawrence Berkeley National Laboratory (LBNL) and the National Renewable Energy Laboratory (NREL) for a free, one-hour webinar that will provide a wide-ranging assessment of the costs and benefits of continued wind turbine scaling in the United States.
We are pleased to release the 2019 edition of Berkeley Lab’s Utility-Scale Solar report, which presents analysis of empirical project-level data from the U.S. fleet of ground-mounted photovoltaic (PV) and concentrating solar-thermal power (CSP) projects with capacities exceeding 5 MWAC.
A new study by Lawrence Berkeley National Laboratory finds that energy efficiency programs for customers of publicly owned utilities saved electricity at an average cost of 2.4 cents per kilowatt-hour (kWh) from 2012 to 2017.
