Last year was a whopper for energy storage. Global battery manufacturing capacity announcements topped 75GWh, while Tesla built the world’s largest-ever battery plant, within 100 days.

Speakers from 22 countries will be gathering at the 10th Energy Storage World Forum and 4th Residential Energy Storage Forum in Berlin next month at a critical point for the industry.

Tesla’s recent pledge to build a 100MWh battery plant in Australia within 100 days, or give it away for free, has put the industry under unprecedented pressure to deliver on its promises.

Tesla energy division boss Lyndon Rive offered to install between 100MWh and 300MWh of battery capacity at breakneck speed in South Australia when he introduced Tesla’s new Powerwall and Powerpack systems in March.

The seemingly throwaway comment was picked up in local news reports and prompted Australian software tycoon Mike Cannon-Brookes to reach out to Tesla CEO Elon Musk over whether the offer was for real.

Musk said it was, and added the Australians wouldn’t have to pay for the system if Tesla failed to deliver it within 100 days of a contract.

Combining battery storage with solar generation is already cheaper than using diesel in most microgrids, said experts at an Energy Storage Report webinar last week.

“As the key applications, we see islanded grids or microgrids, [where] PV and batteries are becoming cost-competitive with diesel,” confirmed Valts Grintals from Delta Energy & Environment in the event organised alongside Ata Insights.

A case in point is France, where interest in solar plus storage is highest in islands and “non-interconnected zones,” where around 60% of PV projects so far have been installed with batteries, Grintals said.

This interest is set to grow following the launch of a tender last year for almost 52MW more of island-based solar capacity, spread across 33 projects. “We expect to see more storage coming into these projects,” said Grintals.

“In France, PV and storage is a great solution to stabilise the grid [and] help enable microgrid use, and it is already cost competitive.”
