Energy Storage

Western Australia is soaked in sunshine, and PV uptake is challenging the grid. But small numbers of medium-sized community batteries are taking the heat off the system, while helping more people to reap the dividends of rooftop solar PV.

Brazil now has 12  GW of underperforming hydropower capacity, according to U.S. researchers. Large-scale floating PV is an ideal solution to offset this shortfall, due to its high capacity factor, load correlation, and high potential output during periods of high demand.

The forecast for the ACT is two big batteries and gale-force winds as the territory’s Government awarded two considerable contracts in its latest ‘reverse auction’, including a 14-year contract with Neoen, the first for its massive Goyder Renewables Zone. 

Around 4.2 MWh of energy storage capacity will be connected to a solar and diesel micro-grid on Rarotonga, the largest of the islands in the South Pacific nation. Three 40-foot containers with a total power output of 4.8 MVA will be used as a power reserve and for grid support by utility Te Aponga Uira.

Solar curtailment might become a valuable aspect of future PV deployment, particularly if grid operators start focusing on ‘curtailment management’ instead of ‘curtailment prevention.’ Management would include measures such as flexible generation, storage, load flexibility, and regional coordination.

After being ignored by the Federal Government, Queensland has announced a $500 million Renewable Energy Fund for state-owned energy corporations to invest in commercial renewable project and infrastructure, a particular complement to QLD’s three pending Renewable Energy Zones.

With 82,000 cumulative system installations, Australia ranks among the world’s leading markets for residential energy storage. But uptake is still sluggish, thanks to long payback periods, and market developments are only now beginning to emerge. That said, forecasts are still bullish for batteries Down Under – it is only a question of when.

South Australia’s first ten-star home was completed last month, a home that consumes twenty times less energy than the average Australian household, in part thanks to its Fimer React 2 solar hybrid system.

The 50% expansion of Neoen’s Hornsdale Power Reserve, otherwise known as the Tesla Big Battery, has been successfully completed. If testing of the upgraded battery goes well, Hornsdale could begin to function with an expanded remit of synthetic inertia services, a capability which could have significant impact on regulatory changes.

The Western Australian Government has launched its new Distributed Energy Buyback Scheme, a way for homes, schools, and not-for-profits with rooftop solar, energy storage, and even electric vehicles (EVs) to earn some money back from the surplus energy they export to the grid.
