The local grid operator’s challenge

Engaging with locally connected distributed energy resources (DERs) becomes an increasing challenge as more connect. The utility was looking to actively transition to the role of a distribution system operator (DSO) and access DERs connected to their network.

The local prosumers’ challenge

In this context, local prosumers were residential customers with rooftop solar and/or batteries. With the feed-in tariffs expiring, there was a need for new financial incentives to encourage rooftop solar uptake in the region.

The local consumers’ challenge

Local consumers were residential demand customers operating electric vehicles (EVs) and smart homes (homes with smart appliances) in this context. Local consumers were interested in providing load shifting services to the grid and accessing local renewable energy from their community, but didn’t have an opportunity to do so.

Solution for the local grid operator

To address these challenges, Electron designed and deployed a market for two types of event:

• Demand response events: London Hydro procured demand turn down service from its customers to ensure grid stability during periods of high demand
• Community energy events: Local prosumers selling their excess solar energy to local customers.

Solution for the local prosumers

Local prosumers with rooftop solar and/or batteries took part in community energy events where they could sell their excess solar energy to local customers.

Trading was facilitated by London Hydro, the local distribution company, with communication to customers via its Trickl app.

Solution for the local consumers

Local consumers provided demand turn-down services in demand response events, as well as demand turn-up services in community energy (excess solar) events.
