Using machine learning and cheap satellite data to design rooftop solar power
Researchers have built a tool to use cheap satellite imagery – like Google Maps – to automatically create solar designs with a 91% accuracy rate.
US utilities approve 551 MW of solar power at 3.8¢/kWh
North Carolina-based Duke Energy has completed a solicitation for 551 MW of solar power through its CPRE program, with average pricing between 3.79¢/kWh and 3.83¢/kWh and 20 year power contracts.
When the battery is a building… or vice versa
AES has announced the start of construction of its Alamito Energy Center, a 100 MW/400 MWh battery for electric utility SoCalEdison which is being constructed as a full-on building – much like a data center.
Los Angeles seeks record sub-two cent solar power price
The city’s municipal utility is readying a 25-year power purchase agreement for 400 MWac of solar at $0.01997/kWh along with up to 200 MW/800 MWh of energy storage at $0.013/kWh.
The Pope, big oil and bankers are talking carbon taxes
Pope Francis held a closed door meeting at the Academy of Sciences with the CEOs of oil firms and investment firms to address climate change, with a group committing to support an “economically meaningful” carbon price.
Bifacial beats Trump’s tariffs
Federal trade authorities have ruled that bifacial solar modules are no longer subject to the Section 201 ruling, which currently apply a 25% tariff to most solar modules imported to the United States.
New York’s winter solar duck curve is on the way
A site origination exercise and load analysis by Cornell University suggests 9 GW of solar will reduce peak demand in New York by nearly 10%. However it also found solar needs better capacity valuations to make for a stronger market, and will drive a winter time duck curve during a season of lower electric demand.
Designing for and monetizing curtailed solar power
Research by NREL and First Solar has produced highly accurate, real-time estimates of available aggregate peak power that a curtailed solar power plant can deliver to support the broader needs of the grid.
California is learning to trust 100% residential solar power
California utility PG&E has tested levels of residential solar power up to 100% penetration, and how to mitigate the effects of voltage and thermal overload via smart inverters and traditional transformer and circuit upgrades — with smart inverters shown to allow for up to 100% penetration at cost-effective pricing.
California just made more clean energy than it needed
The state grid operator has shown that for most of the period between 1:50 PM and 3:05 PM on Sunday, more carbon emission-free electricity than users demanded was generated in its region.
