As we optimise your on-site power generation based on real-time market conditions, contracting with Hartree as your gas and power supplier is key in enabling our team to pass through the full value of savings to you.

Choosing Hartree as both your supplier and optimisation partner allows us to supply your power through either on-site generation or the National Grid depending on which supply source is the most financially and/or environmentally beneficial in real-time. When power prices are negative, and the network is paying users to stop generating we enable you to participate and benefit from these payments which are only achievable by a fully licensed Gas & Power Supplier.
