Grids & Integration

A vision of a decentralized, renewable-powered electricity grid is being brought a step closer by scientists at the U.S. National Renewable Energy Laboratory. Their project, Autonomous Energy Grids, aims to take an overarching look at the solutions that will power this grid of the future, and to fill any gaps that appear between them.

Researchers have built a tool to use cheap satellite imagery – like Google Maps – to automatically create solar designs with a 91% accuracy rate.

A new report from analysts at Wood Mackenzie forecasts 6.6 GWh of residential energy storage to be installed across Europe by 2024. The economics of the technology are at a tipping point, increasingly reaching grid parity in European markets. With rising electricity demand and falling battery system costs, the trend will further spread across the continent and fuel an uptick in demand.

Railway operators can now feasibly connect solar plants to traction substations, claims a consortium that is now working on a similar demonstration project in the U.K. Almost all of the 30 kW installation’s output will be used to move trains, but in the future storage could come into the picture for larger “railway-connected” solar power projects, says 10:10, the U.K.-based climate change charity that developed the pilot.

The high efficiency solar panel maker pulled off a rare profit in the second quarter due to selling off leases, but expects to report another quarterly loss in its next update.

With grid capacity a limiting factor, the Middle Eastern country has moved to foster private-to-private solar projects to meet industrial power demand.

The analyst has published its latest Energy Storage Outlook report and says large scale deployment will provide the majority of the 1,095 GW/2,850 GWh of battery storage worldwide in 2040, with prices driven down further by grid services demand and EVs.

The scheme will test the potential of distributed energy resources such as rooftop systems, battery storage and controllable load devices aggregated into VPPs to provide scalable energy and network services traditionally performed by large scale, conventional electricity generators. With registration open, the Australian Energy Market Operator wants VPPs to register to accelerate shared learning.

The Palo Alto company says it has improved its large scale battery offering with the new product in the wake of the success of its Powerpack-driven big battery in Australia. The Megapack can be deployed at a 250 MW/1 GWh clean energy plant four times faster than a fossil fuel alternative, claimed the business in a blogpost.

Previously known for its automotive activity, CATL is turning to another promising sector to generate demand for its battery cells. With the first few hundred thousand Japanese solar households seeing their 10-year FIT contracts expire, demand for small scale storage is on the rise
