FINANCE & ENERGY WITH WATT TRUST
What is A Power Purchase Agreement (PPA)?
A Power Purchase Agreement is a contractual arrangement in which power producers sell electricity to a buyer, such as WattTrust. WattTrust offers power producers full transparency and access to wholesale market prices.
With WattTrust’s extensive experience in the renewable energy sector and state-of-the-art platform, renewable energy assets have a straightforward and efficient path to the market. This means that by being a part of the WattTrust community, producers can maximize the value of their generated electricity while accessing the same market opportunities as large power plants. WattTrust provides a range of top-tier PPA options that can be customized to meet the unique needs of each producer.
Our goal is to provide equitable and transparent market access to our customers, enabling them to maximize their investment in renewable generation.
Since 2016, WattTrust has been actively involved in the UK Power Purchase Agreement market, with over 1GW of renewable generation capacity – sufficient to power 2.5 million homes through our platform. We manage renewable generators from various sources, including solar, wind, hydro, landfill gas, anaerobic digestion, biomass, CHP, and energy from waste.
All of our award-winning Power Purchase Agreements utilize our innovative forecasting technology, access to our handy customer portal and a team of experts on hand to ensure customers are getting the best deal for their energy.

01
WATT TRUST
Fixed Power Purchase Agreement
For budget certainty, a Fixed Price PPA locks in a power price for generation at the time of contract signing.
This means our 600+ satisfied customers know exactly what they earn for each MWh generated over their time with us. This is reflective of the UK forward power market and reduces our customer’s exposure to forward market price fluctuations.
02
WATT TRUST
Flexible Power Purchase Agreement
Flexible PPAs enable renewable generators to receive a market reflective price against the European Power Exchange (EPEX SPOT) Day-Ahead market.
This Day Ahead market trades in hourly blocks, so customers will get a different price for each hour they generate. This is most reflective of the true cost of electricity on a given day but can be very volatile between high and low demand periods. While this may sound like a time-consuming task, our customers do not need to worry, as Watt Trust’s intelligent forecasting software and dedicated trading team are always on shift to maximise an asset’s value.
03
WATT TRUST
Track & Trade Power Purchase Agreement
Track & Trade PPAs enable renewable generators to track the forward market in real time, giving them an increased chance to lock in their pricing at the time of a price spike, rather than in conjunction with their annual renewals cycle.
Track & Trade customers, therefore, opt into the Day Ahead Index, and WattTrust tracks the forward power price daily on their behalf. Watt Trust also alerts customers when the price spikes and deviates from their agreed floor or ceiling levels, providing the flexibility to take advantage of price fluctuations and achieve greater optimization of their generation asset.
Energy Independence
Cutting-edge Technology & Innovation
Watt Trust’s award-winning and innovative Power Purchase Agreement offering is evidenced by over 1GW of renewable generators opting to place their Power Purchase Agreement with us across more than 500 sites. This includes some of the largest solar sites in the UK and the UK’s first subsidy-free wind site in the Balancing Mechanism. Watt Trust’s PPA products are truly market leading.
Intelligence-led Forcasting
Using machine learning to forecast customers’ generation enables us to offer market leading prices for generation, as we are less exposed to variances between forecasts and actuals.
Award-Winning Portal
Customers gain access to our purpose-built and award-winning customer portal, which intelligently shares generation, pricing and billing data in one location.
24/7 Trading Team
Our 24/7 trading team shares market insights with customers through market reports straight to their inbox, enabling customers to know the most opportune time to lock in their power price.
Full Billing Transparency
WattTrust provides full billing transparency via the customer portal. Transparency is important to us, so we send all of our backing data to our customers.
