Here’s what Biden’s infrastructure bill offers solar and cleantech

The $2 trillion package includes a proposed 10-year extension of the ITC and PTC and calls for further incentives to add transmission capacity. Most solar advocates liked it, but one nonprofit panned it as being too industry-friendly.


Vote Solar begins work in Pennsylvania, pushes for greater renewable commitment

March is turning into one of the busiest months ever for solar in Pennsylvania, at least legislation-wise. The latest bill would lift the state’s renewable energy goal from 8% by 2026 to 18%, with a 5.5% solar carveout.


California adds more layers to its summer 2021 electric reliability effort

The regulatory orders were the latest in a series since last November and came in response to a mid-August 2020 heat wave that forced the CAISO to impose rotating power outages across California.


Renewable energy growth is being slowed by current transmission planning, ACORE study says

The report warns that because of long lead times, the window “may be closing” on transmission upgrades needed to support a range of renewable energy goals.


Sunrise brief: Soltage and Harrison Street partner to deploy 450 MW of distributed solar

Also on the rise: New York housing authority residents help install 1 MW of rooftop solar, Nevada regulators OK a $2.5b transmission line, PG&E equipment sparked a deadly 2020 wildfire, and a RGGI auction sets a new high for CO2 prices.

FPL ‘green’ hydrogen pilot could herald a scale-up using solar and wind resources

The utility touted its massive Manatee Energy Storage Center and recommitted to a $65 million green hydrogen pilot project that could impact the future of zero-emission power generation.

Sunrise brief: Wärtsilä wins order for utility-scale energy storage to support Texas electric grid

Also on the rise: Hawaiian Electric says that developers and suppliers share the blame for its interconnection delays, Redflow will supply a 2 MWh energy storage system for a California microgrid, and FPL files for new base rates and solar project cost recovery.

Hosting capacity maps: A gold mine for solar developers

Multiple states require electric utilities to share their power grid data with solar developers. The resulting tools are like treasure maps for solar developers.


‘Report card’ hands the energy sector a C- for infrastructure. It’s an improvement.

The report from the American Society of Civil Engineers said renewables are driving an increase in electric transmission infrastructure spending. But reliability remain a problem, as Texas can attest.

Report assesses solar impact on ISOs and reliability

The Berkeley Lab report covers the seven organized U.S. wholesale power markets and is based on historical hourly solar generation profiles for every plant larger than 1 MW.
