One integrated energy solution.

One accountable partner.

Norwegian battery engineering meets British energy systems expertise to accelerate the transition to a cleaner, more resilient grid. 

ep Pixii takes Pixii’s advanced modular BESS and pairs it with end-to-end energy system design, EMS integration, and performance optimisation.

We handle the complexity – so you don’t have to.

End-to-end BESS solutions

ep Pixii manages the full journey of each energy solution, from early feasibility and system design through commercial structuring, engineering, construction, commissioning, and integration. By bringing all stages under one model, we provide a single point of accountability and clear ownership from start to finish.

Markets

Commercial & Industrial BESS

Integrated solutions that reduce operating costs, improve resilience, and unlock value from flexibility

EV Charging BESS

Integrate EV charging into your wider energy system without increasing costs or adding to grid constraints

Utility Scale BESS

Large-scale grid-connected systems that deliver flexibility, stack revenue streams, and support grid stability as renewable capacity grows

Technology for long-term system performance

At ep Pixii, we know that not all technologies are created equal – we carefully select hardware and software based on how they perform within an integrated energy system over time.

Every platform and component is chosen for resilience, security, scalability, and long-term value to ensure our solutions remain adaptable as markets, regulation, and site requirements evolve.

Our principles

Modular construction

Pre-engineered modular design delivers safety and reliability through standardisation. Modules can be added, upgraded, or serviced individually, minimising downtime and maximising flexibility across use cases. Post testing and validation, we quickly deploy improvements across a fleet with predictable costs and outcomes.

Scalable by design

Modular BESS architecture allows us to scale from 10kW/10kWh to 10MW/50MWh, adding power and storage incrementally as business or market needs change. Design flexibility allows pilot projects to grow into full commercial systems and enables solutions tailored to different use cases.

Reliable performance

With over 99% uptime, hot-swappable components, and built-in redundancy, Pixii systems ensure continuous operation. Noise levels and self-consumption are kept below 1% using an advanced thermal management and hybrid cooling system. The 48V architecture and galvanic isolation support safer installation and servicing, while standardised designs streamline permitting, installation, and maintenance, improving overall fleet availability.

Cybersecure & Future-ready

Strong encryption, access control, and GDPR compliance are integrated into every system, in line with international cybersecurity standards. European design and software management underpin physical assets, with independent operation and rigorous testing in place to address digital threats.

Energy resilience

ep group has partnered with Norway’s Pixii AS to meet growing demand for scalable, high-performance battery energy storage solutions (BESS) in the UK market. By combining our deep local expertise with Pixii’s advanced battery and power-conversion technology, ep Pixii is working to accelerate the deployment of cleaner, more resilient energy systems across the UK.
