Tesla Faces Stiff Competition in Energy Storage War

A week after Tesla announced it had won a tender for the installation of the world’s biggest battery storage system in Australia, Siemens and AES launched a joint venture that focuses exclusively on battery storage systems.

The first comments from observers suggest that this joint venture, called Fluence, could turn into stiff competition for Tesla, and there are facts to support this suggestion, Oil Price reported.

Tesla has 300 MW worth of battery-powered storage systems across 18 countries. AES and Siemens boast a combined 463 MW of such projects across 13 countries. Tesla is developing its first lithium-ion battery factory, known as Gigafactory, and plans to build three more. AES has a decade of experience in energy storage systems and Siemens has more than a century of experience in all things energy technology as well as an established presence in over 160 countries.

Bloomberg quotes AES’ chief executive, Andres Gluski, as saying that energy storage is “the holy grail for renewables”.

Gluski is certainly right: The biggest hurdle for the wider adoption of renewable energy in the past has been the lack of reliable energy storage capacity that would solve the pesky intermittency challenge that is inherent in solar and wind power generation.

Battery-based storage systems have their own world-changing potential, including significantly reducing the use of oil and gas for power generation.

There are three drivers to this increased adoption: reliability, sustainability and affordability, as expressed by Siemens’ head of energy for the US and Canada. This is what led Siemens and AES to join their forces.

As Gluski puts it, “We have to mass-produce this product to continue to bring down costs. On long-duration systems, we think we're the most competitive in the market, but we'll be even more competitive if we’re even larger.”

Given the experience, reputation and international presence of the Fluence partners, the company could indeed become a serious challenge for Tesla and it is not going to be the last one.
