Previously, the grid was designed to be one way only. It is now changing to two-way energy flows, facilitating exports of electricity as much as imports. One option to enable a two-way energy flow is local energy sharing or peer-to-peer trading. Simply put, energy sharing is where one party produces excess electricity and then shares this with another party. Energy sharing is also known as Virtual Net Metering (VNM) or peer-to-peer energy trading...

It seems such a straightforward concept. You have excess electricity from your solar installation on Building A, you assign this to Building B across the road, which can’t have solar (e.g. is overshadowed). Building A benefits by increasing the size of its solar PV array leading to higher bill savings, and being able to assign or sell the exported electricity to Building B. Building B would benefit by potentially having a lower electricity bill, and a renewable energy supply. Unfortunately, the reality is different...

The treatment of energy generated from solar PV systems is an important consideration for organisations who have carbon reduction or renewable energy targets. Most people know that electricity generated from solar reduces their grid electricity purchases and thus their carbon emissions. However, what causes much confusion is how to correctly account for renewable electricity that your organisation has exported to the grid...

In this blog post, we are investigating nine ways how you can maximise the financial benefit from your excess solar. Among the nine ways that are discussed are negotiating a good feed-in-tariff, netting off your supply and demand, asking your network provider for local network sharing tariffs, considering an embedded network, using battery storage to increase self-consumption from solar, virtual power plants...
