Arizona utility pushes smarter energy use to maximize daytime solar power
Arizona Public Service has announced three new residential energy programs hoping to financially motivate customers to use cheaper daytime electricity via HVAC, energy storage and hot water heaters.
Clean energy versus gas
Solar and energy storage, either on their own or as part of clean energy portfolios, are showing that they can compete with natural gas in the United States. But will regulators wake up to this reality before half a trillion dollars worth of future stranded assets are built?
SMA prepping for ‘exponential growth’, shipping solar inverters ready for AC-coupled energy storage
The SMA Sunny Boy-Storage is now shipping to the United States. The inverter offers 3.7/5.0/6.0 sizes and can accept up to three AC-coupled battery connections. SMA believes the solar + storage market will offer exponential growth.
California grid operator opens doors for behind-the-meter batteries, distributed resources
A measure allowing behind-the-meter batteries to get paid during periods of electricity oversupply was among the measures approved by CAISO last week. Several of the changes are expected to assist with the integration of higher levels of renewable energy.
How far should we push oversizing a solar power plant?
Fluence Energy has given guidance on optimizing solar module loading ratios, suggesting that a 1.9:1 DC:AC solar panel to inverter ratio, in defined circumstances, makes economic sense with integrated DC-coupled energy storage.
Employee owned engineering firm installing advanced electric vehicle charging on campus
Burns & McDonnell, a 6,000-strong engineering firm, is installing a Greenlots EV charging network and integrating it into the company’s campus network. The engineers hope to offer EV related services to their many electric utility customers.
Smarter homes with solar+storage by Sonnen
The Sonnen ecoLinx adds home automation skills, via powerful industry partner tools, complementing the company’s energy storage, grid management and microgrid expertise.
US triples energy storage installations, residential grows 10X to become largest sector
Wood Mackenzie projects that the U.S. energy storage market will reach well over $500 million in sales this year, following on 61.8 MW / 156.5 MWh of installations during the second quarter. Residential storage has grown at 61% per quarter since Q1 2017.
Grid-connected battery energy capacity grew 68 percent last year
A utility survey shows battery storage capacity growing sharply, including solar + storage installations in several states. Looking ahead, FERC Order 841 could spark extensive new storage for grid services, helping more utilities become familiar with storage and its benefits.
California energy storage subsidy extension passes Assembly
A bill to extend the SGIP program through 2026 and add nearly 3 GW of behind-the-meter energy storage has passed the California Assembly. It will now go to the Senate to be reconciled before going to Governor Jerry Brown.
