Lower energy costs
Battery energy storage reduces dependence on peak-hour prices and enables smarter management of electricity consumption – cutting costs today and unlocking additional revenue streams as your energy strategy matures.
Energy storage solutions for business and investment
We guide businesses and investors from idea to commissioning – consulting on, planning and delivering BESS projects that reduce electricity costs, provide energy resilience and generate long-term returns.
BESS solutions in the Baltics from A to Z
From feasibility analysis to permits, equipment supply and operating – we help businesses and investors build future-proof energy storage systems.
Energy resilience
BESS solutions strengthen power supply stability, reduce operational risks and give you more control over energy demand and grid loads.
More efficient use of solar energy
Batteries store the surplus energy produced by your solar power plant so you can use it when its value is highest.
Long-term returns in a growing market
Battery storage parks and business storage solutions are becoming strategic income-generating assets, delivering long-term returns in the growing Baltic energy market.
About Us
BESS partners in the Baltic region
In BESS projects, what you see at first glance is only the tip of the iceberg. The nuances of regulatory compliance, risk management and financing are complex and demand experience.
We help you walk this entire path with confidence. With years of experience in renewable energy, REEI today advises on and guides energy storage projects from idea to successful delivery across the Baltic region.

Process
From potential to long-term value – together
Needs and feasibility analysis
We assess your electricity consumption, peak periods and storage needs so we can propose the optimal solution.
Solution proposal
We prepare an individual proposal with the most suitable system, investment size and payback forecast.
Design, documentation and equipment supply
We obtain grid operator (ESO) conditions, prepare the technical design, handle permits and approvals, and take care of sourcing and delivering the required equipment.
Installation and commissioning
We install the system, run tests, hand it over to the grid, put it into operation and provide remote monitoring.
Investment opportunity presentation
We introduce you to the Baltic BESS market and REEI’s projects open for investment, and discuss opportunities to develop a new project.
Project selection and due diligence
We shortlist the most promising opportunities, assess technical, financial, legal and regulatory aspects, and prepare a preliminary budget.
Financial modelling and risk management
We prepare IRR, NPV, payback, revenue stream and project risk modelling, and help secure any missing financing through banks, support schemes or other funding sources.
Development and optimization coordination
We guide the project through permitting, grid connection, procurement of quality equipment, installation and operation, targeting stable long-term returns.
