Partnering with Green Hedge allows a wide range of large power users to harness energy storage with no upfront investment or risk.


"Savings in a Box" is a small but powerful energy storage system that connects to the switch panel of a commercial or industrial energy user. By shifting the import of electricity from the grid away from periods of high energy and network costs, this creates substantial savings for the energy network and the customer. Designing, installing, financing, and operating the system Green Hedge can help customers reduce their energy bill and carbon footprint.

How it works

1. The conventional energy starting point

Many businesses are still exclusively powered by electricity from the grid, and/or with diesel generation where there is a need for back-up or off-grid solutions. The near-term cost of power is driven by power purchase arrangements with large electricity suppliers, and in the long term shaped by the cost of the grid’s sources of generation and the cost of transmitting power through the national and local grid. Powered this way, a business is tied to the lowest common denominator energy outcome. Level and predictability of energy prices, stability of supply, and carbon intensity are only ever as good as the complex, slow moving arrangements underpinning the electrical grid – and/or the reliance on diesel – can allow. And for ambitious businesses, that may simply not be good enough.

2. Integrating behind-the-meter power

At Green Hedge we partner with large energy users to design, develop and deliver tailored behind-the-meter electricity generation and/or storage projects that complement or replace our clients’ conventional power supply. For partners who prefer to meet their energy needs without CAPEX expenditure, we offer fully financed solutions where power is delivered via a long-term PPA (power purchase agreement) and the financial benefits of energy cost savings begin feeding through immediately. For those who wish to own their generation assets on balance sheet we can deliver a turn-key project, including operation and maintenance assistance once the installation is commissioned. If there is land available on our partners‘ premises that is typically the ideal solution, but if not we can often reach an agreement with a landowner nearby. And some technologies, like electricity storage, have a very compact footprint to start with.

  1. Consultation to asses full range of operational, financial, and other priorities. Presentation of shortlist of best-fit technology combinations and project sizes ranked by how well they deliver across the identified objectives.
  2. Construction of the selected low carbon generation and/or storage plant on site or nearby.
  3. Connection of new low carbon generation and/or storage plant to partner‘s existing customer-side substation.
  4. Partner’s facility now powered by customised low carbon generation, with electricity from the grid only used for top-up or back-up if required.

Case study: The sun is powering Honda’s largest factory in Europe

Green Hedge developed both solar farms and created the commercial and legal structure for these multi-party projects.

Working as partners

Honda of the UK Manufacturing (HUM) is a fully integrated car manufacturing facility currently producing the CR-V, Civic 5 Door, Civic Tourer and the all new Civic Type R for the European market. It is a major employer in the local Wiltshire area, and among the largest single-site electricity users in the UK. Since 2011, Green Hedge has worked with HUM to develop first a 5 megawatts solar farm (2011) and then a larger 10.3 megawatts installation (2014), that now help power its main European factory.

Green Hedge worked with neighbouring landowners to secure the land, obtained all permissions, and structured the arrangements that also brought on board the long term investors that own the solar farms today. 

Delivering power and 7,000 tonnes of annual CO2 savings

Together, the two solar farms generate c. 14,500 megawatt hours, saving Honda over 7,000 tonnes of CO2 each year. The electricity is purchased by HUM under a long-term power purchase agreement (PPA). While the bulk of the electricity generated is consumed by Honda, any excess (at weekends or during HUM’s annual shutdowns) is fed into the electricity grid and purchased by UK green electricity supplier Good Energy. In addition to the two large solar farms, HUM and Green Hedge installed 5 kilowatts of Honda-manufactured solar panels near the revolutionary hydrogen refuelling station at HUM. The electricity generated by the solar panels is used to split water into oxygen and hydrogen, which is then compressed and used to fuel hydrogen vehicles.

The Green Factory

HUM’s Andy Milkins describes the private wire solar farms as a win-win solution for Honda and the environment: “Reducing Honda’s reliance on fossil fuel is a serious commitment for us. Our ambition is to get 100% of our energy from renewable sources – the “green factory” is a frequent topic for board level discussions. In Swindon, the two solar farms already provide 15% of our total electricity demand, equivalent to 100% green electricity for our engine plant.”
