What we do

Working towards a zero carbon future

We adopt a data-led approach. We use the data, and our understanding of your energy needs to identify the best fit technology solutions to reduce costs and be more sustainable.

What solutions do we provide?

Cost & Carbon Reduction Measures

We understand that many energy intensive manufacturers are facing the dual challenge of containing energy costs and reducing CO2 emissions. Environmental performance reporting is now a feature of annual accounts and so CO2 and energy intensity KPIs are reported on, with year-on-year performance being compared, and often scrutinised by stakeholders. We are able to design and deliver projects that tackle both problems through the delivery of a best-fit solution that unlocks the customers full sustainability potential. We look to support our customers in implementing the measures identified.

Project Enablement

We often find that engineering teams have a stock of their own great ideas, sitting on the metaphoric “shelf”, but need approval and resources to execute them. Likewise, sometimes engineering teams are keen to get a fresh view point, which may bring to the table other innovative solutions available. We have worked with companies on projects that have not been able to progress past the concept stage due to resources being limited, and we have been able to provide the human and financial resourcing needed through or commercial model and supply of project management resources.

Sustainability Enablement

We will also support customers in achieving their Science Based Targets and other sustainability objectives. Once we have gained a detailed understanding of your site’s current and forecasted energy requirements, we will create a net-zero roadmap that is in-line with your corporate sustainability commitments.

Energy Savings Journey

Zero Capex partnership solutions

A key barrier to the adoption of energy savings measures is payback criteria. This can be due to a lack of cash in the business with which to invest, but is also often driven by balance sheet management and credit rating requirements. Under this commercial model, the measures that are implemented have a typical 15–20-year operating life and improve operational efficiency as well.
A solution to capex payback restrictions is our zero capex energy partnership model.
Under this model:
  • we agree the specification of the equipment with you to ensure we are aligned
  • we then pay to secure all necessary permissions
  • we undertake the engineering
  • we agree performance criteria and interfaces between us
  • we project manage and deliver the project, taking CDM responsibilities where required
  • we pay for the equipment and the installation
  • we own, operate, and maintain the equipment
  • you pay for the output of the equipment on a metered basis, at agreed prices. The prices agreed allow us to make our required returns, but still deliver savings to you against what you would have paid otherwise, also saving on maintenance fees.


Why engage?

Pressures are building on manufacturing businesses to both reduce costs and become more sustainable.

Governmental policy is to decarbonise by 2050. This will be achieved partly by decarbonising the grid, and encouraging the switch to electricity, but also through legislation that forces change. The cost of this will be felt in higher non-energy costs in bills, but also the direct actions that companies will need to take in order to mitigate carbon taxes and achieve compliance with legislation. An example of such legislation might be that implementing ESOS recommendations become mandatory.

Manufacturers are going to face a tsunami of capital investment requirement in the years to come, caused by regulatory change and pressure from customers and investors to be more sustainable.

For many low-margin manufacturers, energy costs are one of the largest operating costs. Energy prices have been going up steadily but events such as Russia’s invasion of Ukraine have caused gas and wholesale electricity prices to spike, causing massive pressure to act.

On-Site Energy can assist in bridging that gap through our zero-capex energy partnerships. Under this model, we invest in high specification solutions that bring down your energy costs and improve sustainability credentials, structured in a way that is off-balance sheet.

Why work with us?

Project Design

We do not charge for our initial data analysis and concept design.

We look to review as much of your energy data as possible. This includes:

-Half hourly gas and electricity data
-Sub metering
-Gas & electricity invoices.

We will also conduct a site visit to understand the site’s needs and logistics.

Independent of any technology or vendor, we will design a best-fit solution that achieves your corporate objectives. We will then review initial engineering and supplier engagement to establish budget costs and indicative savings.

We will then present our findings and proposed next steps clearly and transparently, with options for both capex and zero capex based on our assumptions and estimates to that point.

The P.D.A provides the scope between On-Site Energy and Customer to develop the project further. Provides the basis for On-Site Energy to incur costs to secure permissions and undertake detailed engineering.
