Utility Scale Storage

The head of Mercom Capital says solar has a long way to go before it can stand without policy support. Effective grid parity will only be achieved when the cost of PV electricity factors in the expense of grid upgrades and the storage systems its intermittent nature requires, says Raj Prabhu.

Increased storage and strategic transmission development will be needed to ensure the most economic and lowest risk transition of Australia’s energy system, the Australian Energy Market Operator said in its latest study. In 20 years’ time, the need for storage will be at a scale not seen before in the national electricity market, and pumped hydro and distributed storage are set to play major roles in lowering electricity prices and building a reliable and resilient power system.

With a glut of solar capacity having come online this year, cheaper financing would help keep some of that momentum but policymakers cannot be persuaded of the economic benefits of clean energy unless state-owned utility EVN opens up.

While the nation’s recent Union budget announced steps to create an electric vehicle market, the solar sector still has issues that have not been addressed.

The world’s biggest solar market could be about to replicate that feat in energy storage, provided it manages to reform the payment system for rewarding the grid services offered by batteries.

AES has announced the start of construction of its Alamito Energy Center, a 100 MW/400 MWh battery for electric utility SoCalEdison which is being constructed as a full-on building – much like a data center.

The energy transition is accelerating, Ernst & Young global energy leader Benoit Laclau has warned grid operators, thanks to the confluence of digitization, decentralization and decarbonization. Traditional utilities must get with the program or be swept aside.

One of Australia’s largest utility scale solar arrays – and the biggest energy storage facility – has secured approval.

Several new concepts in lithium-ion storage technology have the potential to greatly the increase the energy capacity of batteries. Among them are lithium metal anodes, which could potentially increase energy density by more than 50%. With a newly optimized electrolyte, scientists at the University of California, San Diego have taken another step toward making the idea a commercial reality.

The Chinese lithium-ion battery producer has taken significant stakes in two U.K. entities associated with a mine which could hold up to 8.8 million tons of the raw material in clay deposits.
