Energy Storage

SUSI Partners has bought a 50% stake in Macquarie Capital’s 63 MW / 340 MWh distributed energy storage portfolio in Southern California. Included as part of this purchase is the world’s largest virtual power plant.

Rajasthan Electronics & Instruments (REIL) has invited bids to set up 1.7 MW (AC) of grid-connected PV projects with battery storage in India’s Andaman and Nicobar Islands. The projects — to be implemented on a turnkey basis on Havelock Island (Swaraj Dweep) and Neil Island (Shaheed Dweep) — will be awarded through competitive bids, followed by a reverse auction.

Solar households that choose to participate in the trial in New South Wales will receive direct cash payments of up to AUD $135 ($95) per year, depending on the size of their battery systems.

The New Development Bank has agreed to offer a $180 million loan with sovereign guarantee to Eskom. The utility, which is based just outside of Johannesburg, plans to build new infrastructure to integrate 670 MW of unspecified renewables into the South African grid.

With solar panels already installed on dozens of its buildings, the city of Sydney has upped the ante by vowing to source 100% of its electricity needs from solar PV and wind. The commitment was endorsed by city council last week, with a new 100% renewable electricity contract to be negotiated in the coming months.

A recent Australian National University study shows that newly developed geographic information system algorithms can identify prospective sites for off-river pumped hydro projects throughout the world. The researchers, who identified around 530,000 potential sites, said pumped-hydro installations could enable large-scale energy time-shifting, as well as a range of ancillary services such as frequency regulation, which could help to integrate high levels of PV and wind into electricity systems.

Gridserve has revealed plans to install more than 100 electric-vehicle charging stations throughout the U.K. It will start building the first of these facilities later this year, backed by a £1 billion ($1.7 billion) investment.

Green hydrogen has been exported from Australia to Japan, under a trial executed by researchers from JXTG, Japan’s largest petroleum conglomerate, using Queensland University of Technology’s cutting-edge Redlands Research Facility. The Queensland government has also announced AUD 250,000 ($177,000) in funding toward the establishment of a renewable hydrogen production pilot plant.

Enel acquired developer Tradewind Energy’s 13 GW portfolio of wind and solar+storage projects in the United States, and then immediately sold the 6 GW solar+storage portion to Macquarie.

Australia’s Coalition government has announced funding to support up to 50 off-grid and fringe-of-grid feasibility studies that will investigate whether building a microgrid is cost-effective and whether existing off-grid capabilities can be upgraded with more up-to-date technology.
