Grids & Integration

New research from Stanford University professor Mark Jacobson seeks to remove any doubts about grid stability in a world powered entirely by renewable energy. The latest study models 100% wind water and solar powered grids across the United States, finding no risk of blackouts in any region and also broad benefits in cost reduction, job creation and land use.

China is once again the focus of attention across the global solar PV industry. The country’s manufacturers have had a turbulent 2021, but domestic demand remains strong, particularly from the booming residential rooftop segment. Despite the supply challenges, China will likely reach 50 GW this year and possibly even 100 GW next year. Given the dynamic market and policy landscape, pv magazine publisher Eckhart K. Gouras recently caught up with long-time China solar expert Frank Haugwitz, the founder of the Asia Europe Clean Energy (Solar) Advisory (AECEA).

Large-scale renewable energy generators, including wind and solar PV farms will ramp up to 140 GW from the current 15 GW, more than doubling every decade to 2050 while rooftop solar is expected to increase from 15 GW to 70 GW over the same period as the “accelerating” transformation of Australia’s energy sector continues.

The impression of another big battery being installed on the site of one of Australia’s recently decommissioned “coal clunkers” was lost on few. Battery system provider Fluence says the Hazelwood Battery Energy Storage System’s business case was bolstered by recent reforms and new technology to take advantage of rapidly changing wholesale electricity market dynamics.

Batteries in South Australia have been paid to charge throughout September and October 2021 due to a record number of negative price intervals. Wholesale electricity prices were negative almost 40% of the time.

Simply Energy on Thursday announced it will be extending its Virtual Power Plant program across the eastern seaboard and opening it up to five different battery brands. Simply Energy will continue its technology partnership with SwitchDin to do so, with Ryan Wavish, Simply’s General Manager, and Andrew Mears, CEO and founder of SwitchDin, telling pv magazine Australia they plan to introduce a whole range of new, more advanced features into the VPP as the relationship between the two companies evolves.

Western Australia has today announced the launch of its $35.5 million Virtual Power Plant trial, Project Symphony, which will examine the ways in which residents, utilities, and network operators can join forces to centrally orchestrate the output of rooftop solar, batteries and other distributed resources to best serve both customers and the grid at large.

Fotowatio Renewable Ventures Australia’s 90 MW (AC) solar farm outside Wagga Wagga, New South Wales, has reached the commissioning phase after less than a year of construction. Barring no obstacles, the project should start exporting solar energy to the grid in a matter of months.

Western Australia has become the second state to give network operators the capacity to remotely switch off residential solar systems as an emergency grid stability mechanism.

Rooftop solar drove two negative demand events in South Australia on Sunday, November 21, events which analysts are describing as a world-first for a gigawatt-scale power system.
