Utility-Scale Battery Energy Storage

Powering a more flexible energy system

As renewable generation grows, the electricity system needs greater flexibility to balance supply and demand. Utility-scale battery energy storage provides the infrastructure needed to store electricity when it is available and release it when it is most valuable.

Optimaux develops and delivers battery energy storage projects designed to support the evolving UK energy system while creating long-term value for landowners, investors and the grid.

Store energy. Strengthen the grid. Create value.

Battery storage can respond rapidly to changes in electricity supply and demand, helping to manage intermittency from renewable generation and supporting a more resilient and flexible grid.

Our projects can participate across multiple revenue opportunities, including:

• Energy arbitrage
• Balancing and ancillary services
• Capacity Market opportunities
• Grid flexibility services
• Renewable energy integration
• Network constraint management

From development to operation

We take projects through the key stages of development, bringing together land, grid capacity, planning, technical design, funding and delivery.

Our approach covers:

Site Identification
We identify strategically located sites with the potential to support large-scale energy storage.

Grid Connection
We assess available grid capacity and develop connection strategies appropriate to the project.

Planning & Development
We manage planning, environmental, technical and development requirements to move projects towards construction.

Technical Design
We work with experienced technology and engineering partners to develop robust battery storage solutions.

Investment & Funding
We structure projects to attract institutional capital, infrastructure investors and strategic funding partners.

Construction & Operation
We work with specialist delivery partners to bring projects into operation and optimise their long-term performance.

Built for the future of energy

The UK energy system is changing rapidly. As more solar and wind generation connects to the grid, flexible energy storage will become increasingly important.

Our objective is to develop strategically located battery projects that help unlock renewable generation, support grid stability and provide dependable infrastructure for the UK’s future energy needs.

Investing in the UK’s energy infrastructure

We work with:

Landowners
Unlock the potential of strategically located land through long-term energy infrastructure opportunities.

Investors
Access opportunities within the UK’s growing battery energy storage market.

Energy Developers
Partner with us to develop, finance and deliver high-quality storage projects.

Grid & Infrastructure Partners
Collaborate on projects that support a more flexible and resilient electricity network.

Our approach

We focus on projects where location, grid connection, planning and commercial fundamentals come together.

Rather than developing projects at scale for the sake of it, we focus on creating investable assets with strong fundamentals and a clear route to delivery.
