Battery Based Energy Trading: Next Step After Reverse Metering?

The combination of battery-based energy storage and solar power already has some electric utilities worried.

They believe consumers’ ability to store energy harvested by home solar arrays for later use could be a threat to their business model.

Given that, they’re probably not going to like this latest development in energy-storage economics.

Consumers with home solar power can already use reverse metering to sell excess power back to utilities.

But the ability to store energy in battery packs may also allow them to sell that power to third parties, through a process called “energy trading.”

In theory, this could allow consumers to sell electricity directly to each other, and leave utilities out of the loop. One company is already taking a step in that direction.

German battery supplier Sonnenbatterie recently launched an energy-trading platform for use in its home country.
This setup links homeowners’ solar panels and energy-storage battery packs with management software, which monitors real-time usage patterns and weather conditions.

The ultimate goal is to create a network that supports “peer-to-peer” sales of electricity.

Sonnenbatterie isn’t alone in pushing the concept of energy trading.

In The Netherlands, the Vandebron platform–which already has over 38,000 subscribers–lets consumers contract with a provider, who sets their own price.

The U.K. also has a similar scheme for commercial customers called Open Utility.

And in the U.S., Boston-based Yeloha also attempts to pair subscribers with homeowners looking to sell excess power from their solar panels.
If energy-trading schemes like these succeed, they could represent another evolutionary stage of distributed renewable energy.

Home energy storage allows users to rely less on power bought from utilities, by letting them keep more of the energy from their solar arrays.

But if consumers could also buy electricity from other consumers, that would lessen they need for utilities even more.

That is even reportedly a stated goal of Sonnenbatterie’s energy-trading project.
Of course, the Germany company’s scheme still relies on existing infrastructure to transmit power between users.

So while energy-trading may aim to make utilities obsolete, it still doesn’t posit a way to replace their grids, it seems.
