Battery energy storage infrastructure for the Nordic energy transition
Eltel delivers construction, grid connection and lifecycle services for Battery Energy Storage Systems across the Nordics.
As renewable energy production grows, battery energy storage plays an increasingly important role in balancing the energy system. BESS solutions help store excess electricity and release it when demand increases, production drops or the grid needs fast flexibility.
Eltel helps turn energy storage projects into reliable infrastructure.
From site preparation to long-term performance
Battery energy storage projects require strong technical execution, power infrastructure expertise and reliable lifecycle support.
Eltel supports customers from project planning and site preparation to installation, grid connection, commissioning, monitoring and maintenance.
We work with utilities, developers, energy companies, infrastructure owners and partners who need a Nordic delivery partner with practical experience from critical power infrastructure.
What we deliver
Construction and site preparation
We prepare the physical infrastructure required for BESS projects, including civil works, foundations, cable routes and technical site readiness.
Grid connection
We handle the cabling and connection work needed to integrate battery energy storage systems safely and efficiently into the electricity grid.
Installation and commissioning
We support the installation of battery units and related technical systems, followed by testing, commissioning and operational handover.
Monitoring and maintenance
We provide lifecycle services that help secure long-term system performance, fast response and reliable operation.
Future expansion
BESS projects can often be expanded over time. Eltel supports scalable infrastructure that can grow with future capacity needs.
Upsides for investors and partners
For investors and infrastructure partners, BESS offers exposure to a fast-growing flexibility market driven by renewable energy integration, electrification and increasing pressure on the Nordic grid.
By working with Eltel, investors gain a local execution partner with hands-on experience in power infrastructure, technical coordination, documentation, compliance and long-term service. This can help reduce delivery risk, strengthen project bankability and support the transition from development pipeline to operational battery assets.
Upsides:
- Exposure to a fast-growing market
- Reduced execution risk
- A clear path from development to operation
- Local Nordic infrastructure expertise
- Scalable partnership model
The collaboration between Eltel and E&B Renewables demonstrates how a repeatable delivery model can support battery projects in a market where requirements, supply chains and grid processes are still evolving.
For investors, the upside is not only access to a growing BESS market — but a stronger route to getting projects connected, documented and safely in operation.

Why BESS matters
Battery Energy Storage Systems help create flexibility in the energy system.
They can store electricity from renewable energy sources such as solar and wind, and release it when the grid needs additional capacity. This supports grid stability, improves the use of renewable energy and strengthens the reliability of the energy system.
BESS solutions can also support participation in reserve markets where fast response and reliable capacity are essential.
