Helping the NHS make the best green energy decisions


OnGen for NHS Trusts

Sustainability runs through the core of the NHS’ Long-Term plan, with the UK and devolved governments having set targets of net zero by 2050 or sooner. There is growing and compelling evidence of the health impacts of climate change and air pollution, which is linked to fatal conditions like heart disease, stroke and lung cancer. Academics have linked high pollution days with hundreds of extra out-of-hospital cardiac arrests and hospital admissions for stroke and asthma.

The changing climate is leading to more frequent heatwaves and extreme weather events such as flooding, including the potential spread of infectious diseases to the UK. Almost 900 people were killed by last summer’s heatwaves, while nearly 18 million patients go to a GP practice in an area that exceeds the World Health Organisation’s air pollution limit. As a result of this, the NHS has become the world’s first national health system to commit to become ‘carbon net zero’ by 2040, backed by clear deliverables and milestones.

The NHS has already made significant decarbonisation progress, but as the largest employer in Britain, responsible for around 4% of the nation’s carbon emissions, the NHS must be a major part of the solution if the country is to succeed with overarching climate goals.

With large estates, it can be hard to know where to start or which projects to prioritise. That’s where OnGen comes in. OnGen’s unique software suite equips organisations with the tools and knowledge needed to choose the best green energy improvements for your organisation.
OnGen’s cost-effective pricing plan allows organisations to look across their site portfolios to find the best energy efficiency improvements, onsite renewable technologies and renewable grid-supplied energy contracts. By examining your entire portfolio, it will become clear which projects are most beneficial for not only carbon reduction, but also cost saving.

OnGen clearly paves the way to net-zero energy, with a three-step process.
The three-step process to net zero energy

OnGen offers a three-step process through OnGen Expert, OnEfficiency & OnSupply. Steps can be done holistically or separately.


Step 1:

Reduce energy consumption:

With OnEfficiency, we can help you identify where and what you can do to reduce energy consumption and improve energy efficiency.

By becoming more energy efficient, carbon emissions for your organisation will begin to reduce, along with the cost of energy.

Step 2:

Consider onsite renewable energy and battery storage:

With the OnGen Expert, we can help you explore the feasibility of generating and storing your own energy via a range of onsite renewable energy generation sources, like solar PV and heat pumps.

Switching to generating renewable energy onsite reduces the demand for grid-supplied energy, lowering the cost of energy bills, gaining resilience to grid fluctuations and reducing carbon emissions.

Step 3:

Switch to zero-carbon energy suppliers:

With OnSupply, we can help you find the cheapest green energy tariffs for any grid-supplied gas and electricity demand.

Eliminate the remaining energy-related carbon emissions for your organisation.

Your organisation will be assigned a dedicated account manager, who will offer training support and guidance. Additionally, if your organisation is struggling for time, the Managed Service, where assessments are conducted by the OnGen team on your behalf, can be a great option.

As part of this commitment The UK Government have announced funding to support energy efficiency schemes across the health sector.

OnGen have worked with healthcare organisations supported by BEIS have run a number of successful projects across several areas within the UK have helped 100s of public bodies to identify the most viable sites for generating and delivering renewable energy. Health trusts will be able to bid for funding as part of a £1billion Public Sector Decarbonisation Scheme (PSDS). And public-sector bodies, including NHS trusts, will now be able to bid for funding for energy efficiency and heat decarbonisation measures. Public sector leaders have been provided with a huge opportunity to facilitate the transition to net zero carbon and include interventions that were previously difficult to fund. The fund will be delivered by Salix and will finance up to 100% of the costs of capital energy-saving projects that meet the criteria.

The public sector decarbonisation scheme is open to a wide range of public sector organisations not just local authorities. The scheme is managed by Salix and requires an application for funding to be accompanied by a business case. This is where OnGen comes into it’s own and is game changing for NHS Trusts organisations looking to quantify the all benefits of generating onsite renewables, at scale. The aforementioned project has involved assessing up to eight renewable and low carbon on-site energy generation technologies through intelligent technology during the scheme, OnGen could determine whether technology used by sites across the area were financially viable, before indicating the best system size to deliver return on investment alongside a robust financial analysis thus Supporting Trusts to prioritise and drive the business case that will ‘deliver Net Zero with clear deliverables and milestones’.
