SmartestEnergy secures major PPA contract with CWP Energy, providing route to market for UK’s fourth largest onshore wind farm

SmartestEnergy Limited has partnered with CWP Energy on a hybrid Power Purchase Agreement (PPA) for the Sanquhar II Wind Farm, marking the beginning of a strong partnership and cementing their shared mission to meet the UK’s clean energy goals.

LONDON, 10 December, 2025 – SmartestEnergy, the company helping businesses and generators navigate the energy transition, has announced it is working with CWP Energy, a leading independent power producer (IPP), to provide a route to market for electricity and certificates generated by the 308MW Sanquhar II Wind Farm located in south-west Scotland. SmartestEnergy has been selected to contract nearly two thirds of the output (186MW), demonstrating the scale and importance of this partnership.

The collaboration represents a strategically significant milestone for SmartestEnergy, securing a large-scale PPA that supports CWP Energy’s strategy to achieve long-term, low-risk market access, while strengthening SmartestEnergy’s renewable supply portfolio. The Sanquhar II Wind Farm is a monumental project that is currently under construction, and upon completion, will become the UK’s fourth-largest onshore wind farm. The 308MW facility will feature 44 wind turbines and is expected to generate enough renewable energy to power approximately 335,000 homes annually. SmartestEnergy is contracting 186MW of the capacity, equating to around 700GWh per annum.

Rod Wood MBE, Managing Director at CWP Energy, said: “Securing a PPA of this scale with SmartestEnergy is a key milestone in advancing the Sanquhar II Wind Farm and strengthening our long-term commercial strategy. SmartestEnergy brought the flexibility, expertise, and commitment needed for a project of this complexity, and their ability to structure a robust and future-focused solution has been instrumental. Sanquhar II represents a significant step forward in delivering affordable, homegrown renewable power for the UK, and we’re proud to be working with partners who share our ambition for a cleaner, more resilient energy system.”

James Clark, Business Development Manager at SmartestEnergy, said, “We’re delighted to be collaborating with CWP Energy on the Sanquhar II project and have worked closely with the team to provide a hybrid PPA solution tailored to their needs. Our expertise in navigating the compliance and regulatory requirements associated with large transmission-connected assets has been a key differentiator. Along with our ability to deliver a solution that supports CWP Energy with a bankable route to market, we’ve created a solution that manages the risk of increasing volatility and intermittency challenges.”

CWP Energy currently operates nine wind farms in the UK, with a combined 335MW of installed capacity. Given the scale of the Sanquhar II project, the wind energy company was focused on securing a robust route to market that enabled long-term viability and successful financing. CWP was looking for a contract solution that offered significant flexibility, and selected SmartestEnergy for its proven expertise and capabilities in several key areas.

Backed by the Marubeni Corporation, SmartestEnergy has been able to meet the financial needs of the project by providing competitive market access through PPAs tailored for renewable and flexible assets. The company has also delivered the commercial flexibility needed to support the partnership and the extended commissioning period, offered specialist expertise on CWP Energy’s connection to the transmission network, and offered improved market flexibility during commissioning, enabling CWP to maximise the potential of its assets.

Robert Groves, CEO at SmartestEnergy, said: “Our partnership with CWP Energy demonstrates our capability to support major deals and strengthens our position in the market. The large-scale renewable PPA deal reinforces our commitment to growing our renewable generation portfolio, in turn supporting our C&I business offering including our Traceable Renewable Supply product, which ensures businesses can track and fully disclose their energy supply. We pride ourselves on providing CWP Energy with the contractual flexibility necessary to get complex financing over the line, and we’re looking forward to building on this long-term partnership as the team continues to expand its presence in large-scale clean energy.”
