Grids & Integration

Hawaii utilities seek more renewables, storage and now grid services too

Hawaiian Electric Companies has laid out plans to source the equivalent of 135 MW of solar and 1,378 MWh of energy storage – as well as load shifting and frequency response from distributed energy resources through aggregators.

Massachusetts goes duck hunting

The state has unveiled a straw proposal of its new Clean Peak Standard, which appears to focus on mitigating future “duck curve” effects, as well as meeting winter peak energy demand. And this is good news for solar + battery storage.

pvMB 3/29: Ameresco wins eight projects through SMART, University of Minnesota to go solar

The eagle flies on Friday, and in today’s pvMB we bring your Fluence’s new CTO, ET Solar making a comeback, Pason & Chint’s integrated energy storage solution, and more…

Solar power situational awareness, future research get $166 million

The Department of Energy announced a new tranche of $130 million to fund research in up to 80 new solar power-related research and development projects. As well, ten projects were announced as winners of $36 million in awards to increase solar situational awareness during power grid disruptions.

Solar+storage sited at C&I locations can be the backbone of the grid

An analysis by Station A shows a potential for siting 48 GW of solar plus 22 GW / 42 GWh of energy storage in California commercial and industrial locations, meeting 19% of the state grid operator’s legally binding “Resource Adequacy” requirements.

Reducing the risk of fire with rooftop solar, batteries and microgrids

A new white paper by Sunrun delves into the risks that overloaded power lines pose, and posits solutions to both fire mitigation and reliability with distributed generation.

California sets a new solar output record – and it isn’t even spring yet (w/ charts)

On Saturday afternoon utility-scale solar output on California’s grid peaked at 10,745 MW – its highest level since last summer. More importantly, California is wringing greater flexibility out of its imports, meaning more renewables with less curtailment.

Inertia, frequency regulation and the grid

The old system of regulating frequency on electricity grids with the help of the inertia provided by large spinning masses is under threat by the rise of wind, solar, and batteries. But what will replace inertia-based control, and how will the transition work?

Can you hack the grid using an inverter?

Maybe. But you’d be better off using a laptop. And no, Huawei inverters aren’t going to cause a blackout.
