High-quality ESS solutions
High-quality ESS solutions
No illusions. Just engineering.
We don’t re-label Chinese components as ‘European innovation’. We integrate the best parts and deliver real performance and value with local service.
Welcome to Aema ESS
AEMA OY (ESS division) is a Finnish energy-transition company delivering advanced power-storage and electrification solutions across Nordic&Baltic countries.
About us
We supply high end, bankable energy-storage systems from 215 kWh commercial units to multi-MWh grid-scale assets – enabling our clients to control energy costs, cut emissions, and secure reliable power.
Founded in 2011, AEMA combines engineering competence, financial structuring, and operational execution into one platform.
Our mission
AEMA’s mission is simple: deliver measurable savings, resilience, and carbon reduction through smart energy storage.
We operate with Nordic precision, proven technology, and a results-driven approach that turns the green transition into a competitive advantage for every client.
“Finnish quality multiplied by Chinese manufacturing expertise and low cost approach”
Trusted by
Our work covers four strategic domains:
ESS supply to Professionals
Turnkey ESS systems for solar and wind parks, industrial clients, and grid operators.
Mobile
power
Deployable, zero-emission AEMA-mobile units that replace diesel and bring power to any site within 48 hours.
vPPA
hedging
Virtual power-purchase tools that stabilize electricity costs and link clients directly to renewable generation.
Green
transition
End-to-end decarbonization programs integrating PV, storage, EV charging, and Guarantees of Origin.
For our
green
future
We believe the energy transition must be measurable, transparent, and real.
Every AEMA project supports our clients’ ESG and GRESB goals – cutting emissions, improving efficiency, and building long-term sustainability value.
With every installed system, we track and report:
- CO₂ reduction achieved versus fossil alternatives
- Renewable share of energy use
- Energy savings and efficiency gains
- Guarantees of Origin (GOs) and verified green-energy data
Our clients use AEMA data directly in ESG and GRESB reporting, sustainability audits, and annual disclosures.
Together we turn technology into verified environmental impact – powering industries, fleets, and communities toward net zero.
Commitment
- Cost: Reduce client energy spend and demand peaks; de-risk price volatility.
- Carbon: Replace fossil generators and increase 24/7 renewable use.
- Continuity: Improve power quality and resilience with rapid, mobile, and scalable deployments.

Up to 70 % fuel savings, zero local emissions, minimal noise, remote monitoring, and compliant with EU Green Public Procurement rules.
vPPA - virtual power purchase & hedging tool
Best fit for:
Commercial & industrial consumers (factories, retail chains, logistics hubs) seeking to stabilize energy costs.
Scope:
AEMA provides virtual PPA (vPPA) contracts that hedge electricity price volatility using aggregated renewable generation and storage portfolios.
Clients fix a strike-and-collar price (e.g. €70/MWh with €50–€95 bounds) and achieve predictable monthly energy expenses.
Features:
- Dynamic settlement vs. NordPool spot
- Integrated DSO tariff modeling
- Option to bundle Guarantees of Origin (GOs)
- Flexible terms – 12 to 36 months
- Portfolio backed by AEMA’s ESS fleet and partner solar/wind assets
