Utility Scale Storage

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).

The energy transition and innovation arm of Italian energy company Enel Group is set deliver its first battery energy storage system in Australia, a “landmark project” which it said will help South Australian water utility Central Irrigation Trust “intelligently manage” its energy use.

Australian renewable energy developer Genex Power has penned an offtake agreement with Tesla that will smooth the way for it to secure finance for the 50 MW/100 MWh Bouldercombe Battery Project being developed near Rockhampton in central Queensland.

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.

The 300 MW / 450 MWh Victorian big battery in Geelong has today commenced operation. In spite of fire breaking out during commissioning in July, the battery has been delivered in record time, taking less than a year to build and begin operations.

A consortium including Australian concentrated solar thermal power company Vast Solar has filed to patent a new tank design for thermal energy storage systems. The new design, it says, substantially mitigates the risk of tank failures which have been identified as one of the key shortcomings of the economical storage technology.

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.

Malta announced a partnership with Betchel to deploy electro-thermal energy storage systems that are capable of durations of 10-150+ hours.
