Are Rising Energy Costs Undermining Operational Performance?

For water and wastewater treatment operators, electricity is one of the most significant and volatile operating costs. Continuous reliance on grid power to run pumping, aeration, and treatment processes exposes your site to escalating costs, budget uncertainty, and operational risk.

The key energy challenges facing water and wastewater treatment facilities:

High Energy Demand from Core Processes

Power interruptions can disrupt treatment processes, increasing the risk of non compliance with discharge permits and environmental standards set by the Environment Agency.

Exposure to Energy Price Volatility

Unpredictable electricity pricing makes accurate forecasting and AMP cycle planning challenging, putting pressure on operating budgets and long term financial performance.

Grid Dependence and Infrastructure Risk

Many treatment sites rely entirely on aging grid infrastructure. Grid faults or outages create operational vulnerability for assets that must run continuously.

Net Zero and Regulatory Commitments

Water companies face increasing pressure to deliver measurable carbon reduction while maintaining service levels, resilience, and regulatory compliance.

Energy Independence for Remote and Strategic Sites

Many water and wastewater treatment facilities are located in remote or strategic locations where grid capacity is constrained or connection upgrades are prohibitively expensive. Our solar and battery systems reduce reliance on the grid, providing on site generation that strengthens resilience and supports continuous treatment operations.

Designed to Scale with Asset and Capacity Growth

As treatment capacity expands to meet population growth and regulatory requirements, energy demand increases. We design scalable solar solutions that can be expanded in phases, aligned with AMP cycles, asset investment plans, and long term operational strategy.

Water Treatment Infrastructure Case Study (485 kWp)

"Reducing Energy Costs for Essential Water Services"

When a UK water treatment facility reviewed its operational energy costs and carbon reduction commitments, on site solar was identified as a reliable way to offset electricity consumption without affecting service continuity. A 485kWp solar PV system was installed to support the site’s constant pumping and treatment processes.

The installation delivers measurable financial and environmental benefits:

£130,368 estimated annual electricity savings
407,400kWh of clean energy generated per year
103.3 tonnes of CO₂ avoided annually
High on site self consumption driven by continuous process loads
Improved long term cost certainty for critical infrastructure

Water and wastewater treatment plants operate with continuous pumping and process demand, which typically results in high on site solar consumption. This makes solar PV particularly effective for reducing grid dependency while supporting long term resilience and net zero objectives.

Specialist Solar Solutions for Water and Wastewater Assets

Wastewater Treatment Plants

Wastewater facilities operate energy intensive processes including aeration, pumping, and sludge treatment. Our systems are designed to support continuous base load demand, reduce operational expenditure, and strengthen resilience against grid instability.

Potable Water Treatment & Pumping Stations

Drinking water treatment works and pumping stations rely on uninterrupted power to maintain supply and quality standards. Our solar solutions offset high daytime pumping loads while improving energy cost predictability and operational security.

Sludge Treatment & Resource Recovery Sites

Sludge processing and resource recovery facilities consume significant energy for thickening, digestion, and dewatering. We design solar and battery systems that reduce grid reliance and support stable operation of these high load assets.

Remote & Strategic Water Assets

Many critical water assets are located in remote or grid constrained locations. Our solutions provide on site generation and resilience support for assets where grid outages or capacity limitations pose operational risk.

Frequently Asked Questions for Campsite & Glamping Solar

Are you an MCS Certified installer?

Yes. Fusion Solar UK is fully MCS certified. This ensures all installations meet recognised UK quality and safety standards and provides assurance around system performance, compliance, and eligibility for applicable export or incentive mechanisms.

What types of water assets do you work with?

We work with wastewater treatment plants, potable water treatment works, pumping stations, sludge treatment facilities, and remote or strategic water assets. Each system is designed around the specific operational and electrical requirements of the site.

Can solar reliably support energy intensive processes like pumping and aeration?

Yes. Pumping and aeration processes often operate continuously during daylight hours, which aligns well with peak solar generation. On site solar directly offsets grid electricity used for these high load processes, delivering immediate operational savings.

What equipment manufacturers do you use?

We specify Tier 1 manufacturers known for long term reliability and performance, including JA Solar, Q Cells, SunPower, GivEnergy, and Tesla. Final equipment selection is based on site conditions, load profiles, and resilience objectives.

How does solar improve resilience at water and wastewater treatment plants?

Solar generation combined with battery storage adds an additional layer of energy resilience. In the event of grid instability or outage, stored energy can support critical assets, reducing operational risk and reliance on emergency response measures.

Is solar financially viable for regulated water utilities?

Yes. Water and wastewater facilities typically have some of the highest and most consistent energy demands of any sector. This makes the financial case for solar particularly strong, with predictable savings and attractive payback periods over the asset life.

How does solar help meet Ofwat and Environment Agency requirements?

By improving site resilience and reducing the risk of power related process interruptions, solar supports operational continuity and environmental compliance. It also contributes directly to carbon reduction commitments that form part of regulatory performance assessments.

Can systems be expanded during future AMP cycles?

Absolutely. Systems are designed to be scalable and can be expanded in line with AMP investment plans, capacity upgrades, population growth, or process changes, protecting long term energy strategy.

Will installation disrupt our 24/7 treatment operations?

No. Installations are carefully planned and phased in coordination with site operations and engineering teams. All work is scheduled to avoid disruption to treatment processes, discharge compliance, and service delivery.

Do you provide monitoring and ongoing support?

Yes. We offer comprehensive monitoring and maintenance services, including performance tracking, fault alerts, and optimisation support, ensuring your system continues to deliver operational and financial value throughout its lifespan.

Strengthen your treatment plant’s energy resilience. Reduce operational costs while maintaining compliance and service continuity.
