Trade across the grid with benefits for the customer, retailer and distribution network

What is xGrid?

xGrid lets your customers sell energy from their solar panels to other energy consumers connected to the same electricity grid. From generation to consumption it manages the settlement of the energy transaction between the two parties, allowing for dynamic price-discovery in down to five minute intervals.

Users can tailor their profiles to onboard and sell power in any way they like, all the time building engagement with your electricity brand in several ways:

P2P: Anyone with or without solar panels can trade electricity with their peers.

Loyalty P2P: Shoppers can sell their rooftop electricity to their favourite high street brand in exchange for vouchers. This is a great option for high street brands because it builds brand engagement – footfall and clickfall with their own customers.

Gifted P2P: Customers can simply gift electricity to friends, neighbours, schools and community groups.

Cross Store P2P: Commercial customers can share solar between their stores based in different locations within the same grid, even when only one of them has a PV installation.

Residential to Commercial & Industrial: Commercial electricity tariffs in many countries such as Malaysia, India, the Philippines  are higher than residential tariffs. It makes sense for residential customers with solar to sell electricity to commercial customers for more than the residential rate but less than the commercial one. It also encourages residential customers to install solar.

How does xGrid work?

  • Allows dynamic price discovery, taking into account both the buyer and seller’s preferred pricing as well as the relative amounts of available supply and demand.
