Grids & Integration

Virtual power plants have turned a corner in this country, SwitchDin founder, Andrew Mears tells pv magazine Australia. With the new technology now firmly established, we take a look at the new approaches to orchestration which will inform the next wave of distributed energy resources management.

Green hydrogen can play a vital role in decarbonising the economy and enabling countries to reach net-zero emissions. The economics of producing green hydrogen from electrolysis are maturing as developers scramble to meet expected future demand. Everoze partner Nicolas Chouleur and Neoen hydrogen expert Sacha Lepoutre discuss a case study that shows how stacking different revenue streams could improve the economics of renewable energy projects.

Australia’s energy system was already a complex web, but it’s now transforming into the work of a labyrinth spider, which build tunnels so complicated and thick they look like white silk vortexes. You get the picture. Or you will from reading the Generator Insights 2021 report published today.

With Scottish company Smarter Grid Solutions having already seen its software deployed in the U.K., a pilot project in New York State has been a resounding success for a grid solution the NREL has predicted could unlock swathes of network capacity without the need for new power lines.

Hitachi Energy has won Northern Territory Labor’s tender for the Darwin-Katherine ‘Big Battery’, which is expected to unlock more capacity for residential and industrial PV, generate cost savings of $9.8 million and pay for itself in approximately five years.

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.
