Power Purchase Agreements

Getting more from your renewable generation

What is a Power Purchase Agreement (PPA)?

A Power Purchase Agreement is a contractual agreement where generators sell power to an offtaker, such as Limejump. We offer generators complete transparency while also providing them with access to wholesale power market pricing. Limejump’s vast expertise in the renewable energy industry, paired with our intelligent platform, provides a seamless and easy route to market for renewable assets. This means, as part of the Limejump community, customers can maximise the value of the power they generate while also having access to the same market opportunities as large power stations. Limejump has a suite of market-leading PPA offerings that can be tailored to the individual needs of customers.

Limejump optimises all renewable generators

Our mission is to provide fair and transparent access to the market for our customers, ensuring they maximise their investment in renewable generation. We have been active in the UK Power Purchase Agreement market since 2016, and have over 1GW of renewable generation capacity – enough to power 2.5 million homes via our platform. We manage renewable generators from all sources including solar, wind, hydro, landfill gas, anaerobic digestion, biomass, CHP and energy from waste.

Simplifying the complex

Limejump offers three sophisticated Power Purchase Agreement products

All of our award-winning Power Purchase Agreements utilise 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.

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.

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 have no need to worry, as Limejump’s intelligent forecasting software and dedicated trading team are always on shift to maximise an asset’s value.

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 Limejump tracks the forward power price on a daily basis on their behalf. Limejump 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 optimisation of their generation asset.

Cutting-edge tech & innovation

Limejump’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. Limejump’s PPA products are truly market leading.

Intelligence-led forecasting

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.

Full access to an 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.

A 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

Limejump provides full billing transparency via the customer portal. Transparency is important to us, so we send all of our backing data to our customers.
