Grids & Integration

When the battery is a building

AES announced the groundbreaking 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.

PV interconnection requirements may change with new reliability guidance

Interconnection requirements for mid-sized and large inverter-based systems directly connected to the transmission grid may change based on new guidance issued in draft form by the North American Electric Reliability Corporation. The guidance does not apply to distributed PV.

Solar plus storage virtuous cycle seeks 728 GWh gas replacement opportunity

NREL research projects that as solar power breaks 10% and 25% penetration levels across the United States, energy storage has an up to ~144 GW / 728 GWh opportunity to replace 261 GW of gas peakers.

Massachusetts solar growth a boulder strewn climb

The Massachusetts SMART program is deploying 1.6 GW. The challenges of growth include long interconnection queues in some areas, incentives tapped out in others, equipment requirements increasing system costs, and utilities circling back after approvals to re-asses project interconnections.

Hawaii’s new RFP comes with a side of storage

The plan calls for the deployment of nearly 260 MW of battery storage across the three islands of Oahu, Maui and Hawaii, in addition to renewable development. Could the fixation on storage within this proposal show the state’s determination for peak shifting?

Inside GlidePath’s merchant battery in Texas

The 10 MW project is the largest battery that the company has installed in Texas, and will sell power and ancillary services into the spot market with no contract. It might not be the last.

New York state is going to need 23 GW more solar power

pv magazine USA did the math on the new wind and solar capacity that will be needed to supply power to 20 million people under New York’s new 70% by 2030 mandate. In addition to 6 GW of distributed solar and the 2 GW that has already been awarded in large scale bids, the state is going to need around 15 GW more utility scale solar.

Going 10% solar would save Pennsylvania $619 million per year

Community Energy’s analysis of the Pennsylvanian electricity market showed that 7.5 GWac of solar power would save $619 million a year in wholesale electricity costs while keeping the system’s stability at 100% commercial probability.

Coal and gas red-flagged on reliability; solar doing fine

In an annual report card on North America’s grid reliability, coal and gas are sent to the principal’s office, while solar gains operating guidance related to 2016 and 2017 wildfire-related outages. Texas is cautioned for its lower-than-desired reserve margin, although that was not a problem in 2018.

Solar, storage and wind can keep us on track as far as 2030

This year’s New Energy Outlook report by Bloomberg New Energy Finance predicts renewables can keep us on track for less than two degrees of global heating for the next decade. But after that, other technologies will have to do their bit.
