Electric car company Tesla and solar roof installer SolarCity have quietly been making deals that could one day lead to dozens of sales of battery projects coupled with rooftop solar systems built at both residential and commercial buildings in California.
The Obama administration set a goal on Wednesday of building three gigawatts of solar, wind, and geothermal power capacity on U.S. military installations by 2025 that could require about $20 billion in private financing.
To achieve the best possible prediction, forecasts from multiple suppliers and various renewable energies are summarised into an optimised meta-forecast for the next day. The collective result represents the entire projected volume of green electricity and enables eco-power to be marketed in advance on the European Power Exchange (EPEX).
Grid operators have to deal with electricity from solar PV coming back at them in highly varied waves. Utilities also have to worry how much less electricity they are going to sell. Battery storage systems and battery electric vehicles connected to the grid offer other alternative solutions. But what are the best kind and size of batteries, and what is the best way to connect them?
Intended to support large daily loads where the batteries are cycled regularly, Trojan's industrial product family is targeted at large off-grid PV systems, off-grid hybrid PV systems, grid-tied PV systems with battery backup, smart grid peak shifting systems, and a variety of other applications.
The possible acquisitions are aimed at providing bundled PV and storage systems to commercial properties in Europe and the U.S., including shopping centers or supermarkets.
Pike Research has announced that investments in Community And Residential Energy Storage (CRES) systems will increase to more than US$4.2B in the next decade. Total global installed capacity for CRES systems will reach 780 MW by 2022.
"Using the power that [roof top solar panels] generate, you can aggregate that together and then use storage devices to make up any gaps that you may have or provide services for the electricity grid," explained [an engineering analyst involved with the project].
A joint research project between the University of Southampton and lithium battery technology company REAPsystems has found that a new type of lithium battery has the potential to improve the efficiency and reduce the cost of solar power.
Rural electric cooperatives, which serve many areas rich in wind and solar potential, increasingly are using energy storage as a means of integrating these variable resources into their systems, according to an NRECA executive.
In a previous blog, we reported on a proposed decision pending consideration by the California Energy Commission (CEC), which would allow solar photovoltaic project developers to opt-in to the CEC's permitting process. The CEC has announced that its decision on this matter has been postponed to an as-yet undetermined date.
Kyocera will package its solar panels with Nichicon's battery management system, storage unit and power inverter. The lithium ion battery is made by Samsung.
Most DG units rely on intermittent energy sources, such as wind or solar, which could create voltage and frequency fluctuations in the main electric grid. To remedy this issue, utilities have to deploy smart grids and advanced electricity storage and managing systems.
Science Applications International Corp.'s client, the Kauai Island Utility Cooperative (KIUC), has filed to build a 12MW solar photovoltaic (PV) project which includes an integrated battery storage system.
Bank of America's Merrill Lynch unit and SolarCity have agreed on financing as much as 300MW of solar panels on as many as 120,000 military housing units at bases across the U.S. Called SolarStrong, the five-year plan is potentially the largest residential solar project in U.S. history and worth more than $1B.
