Grids & Integration

Sun Cable is seeking to develop the world’s biggest intercontinental solar and storage project, and has now inked a deal with the Indonesian government that could unlock more than $170 billion (USD 115 billion) in renewable energy generation and transmission operations in the archipelago.

Residential, commercial and industrial solar generation in South Australia has returned to normal operations following heavy curtailment by authorities working to stabilise the grid after storms caused extensive damage to transmission infrastructure.

New Zealand’s solarZero says it aims to provide fast, sustained reserves with its virtual power plant of 10,000 household battery systems. Meridian Energy, meanwhile, has secured approval for a 100 MW battery energy storage system – the country’s largest such system to date.

Construction has begun on a 50 MW/50 MWh battery near the outback city of Broken Hill which will be equipped with advanced inverter technology designed to improve system strength in regional New South Wales and support increased levels of renewable energy generation in the area.

Developer Energy Estate has signed a deal with Abergeldie Complex Infrastructure, which has designed vertical manmade caverns for hydrogen storage. Energy Estate co-founder Simon Currie says the partnership is about shoring up projects like its proposed 1.6 GW Hunter Hydrogen Network.

The New South Wales government will stage a competitive tender to secure at least 600 MW of long duration storage as well as 380 MW of firming capacity as the state looks to fill the gap created by the impending closure of the country’s biggest coal generator.

Western Australia’s largest virtual power plant, the government-support Project Symphony, is live. The project is particularly noteworthy for its introduction of new markets to reward different services and its use of Dynamic Operating Envelopes.

“Integration” was the war cry at this year’s All Energy conference in Melbourne, with an unmistakable push, especially among ‘premium’ brands, toward vertically stacked product suites bundling solar, batteries, energy management platforms, virtual power plants and electric vehicle chargers into one super solution. How big is the market for such a proposition in Australia though? And does streamlining stymie flexibility? pv magazine Australia spoke to a number of brands on the promise, and limits, of the full stack strategy.

While near neighbours, the electricity generation of the countries of Southeast Asia couldn’t be further apart. Indonesia burns locally mined coal, Malaysia has reserves of oil and gas, while populous Singapore, Vietnam, and the Philippines, depend on fossil fuel imports. They could all benefit from increased solar imports, but higher grid capacities and interconnection are key for an opportunity to unlock the power of the sun.

Singapore-based Sun Cable, which is seeking to develop the giant Australia-Asia PowerLink (AAPowerLink) consisting of up to 20 GW of solar and 42 GWh of energy storage on a 12,000-hectare site in the Northern Territory, is forming a consortium to advance sustainable smart energy grids in Asia.
