We need to find sustainable ways of meeting increased demand for services created by a growing population, whilst taking into account the effects climate change will have on our region. In response to this challenge, we set ourselves the ambitious target of becoming a carbon neutral organisation by 2050. Our renewable energy strategy is fundamental to achieving this goal.


Reducing the impact of climate change is a global challenge, and we have an important responsibility to reduce our carbon footprint. The consensus of the scientific community is that anything less than a significant move towards carbon neutrality will have serious consequences for the environment.

Reduce Carbon Reduce Cost is our leading approach to measuring, managing and reducing our carbon emissions.


We have achieved a significant reduction in our carbon emissions:


Capital carbon - the carbon associated with the construction of our assets.

Reduction in emissions from 2010 baseline = 57%


Operational carbon - the carbon associated with running our operations. 

Reduction in emissions from 2015 baseline = 20%

Our strategy includes: working with our supply chain to reduce the energy and materials needed to construct and maintain our assets, increasing the efficiency of our equipment, making better use of the by-products from water treatment processes and generating renewable energy to power our operations.

Renewable Energy Strategy


Our region’s flat geography means it takes a huge amount of power to take water from the environment, treat it and pump it to customers. We then need to collect, treat and return recycled water safely to the environment. Generating our own electricity from renewable sources helps us significantly reduce carbon emissions, as well as cutting our operational costs.


Renewable energy generation forms a key component of our broader energy strategy and represents a significant step towards our ambitious goal of becoming a carbon neutral organisation by 2050.


To achieve this goal we are continuing to invest in our Combined Heat and Power (CHP) fleet, as well as increasing our use of solar power on operational sites. We are also exploring opportunities to increase renewable energy generation from organic wastes, wind and energy storage



We have ten existing sludge treatment centres and Combined Heat and Power (CHP) engines which create energy from the gas released as a by-product of the water recycling process.

Through our bio-resources strategy we are maximising the generation of renewable energy from these by-products, and we are also working with the agricultural sector to recycle these nutrients to land. Most of the renewable energy generated is used to power on site operations, with any excess being exported to the local electricity networks.


We have a growing number of solar arrays installed on our operational sites. We also are trialling an energy storage solution allowing us to store excess solar energy generated during the day and use it at other times, helping us to reduce our reliance on energy from the grid.


We have three existing wind turbines which generate about 14GWhs of energy per annum and we are continuing to explore wind power in places where it would be appropriate.
