Revenue model
- Energy Storage System Development and Sale: Lehto develops, constructs, and sells battery energy storage systems. Projects are executed through dedicated project companies (SPVs) offering transparent investment structures. Revenue generated from capacity fees, system sales, and grid services.
- Energy Storage System Leasing: Flexible leasing model for battery capacity and complete energy storage systems. Lehto pays property owners for hosting the storage system and covers equipment costs, providing risk-free returns for landowners.
- Grid Reserve and Frequency Regulation Services: Revenue from providing frequency and power regulation reserves to transmission system operators (TSO) like Fingrid. Energy storage systems participate in ancillary service markets for grid stability.
- Property Energy Storage Solutions: Turnkey battery solutions for properties including installation, integration with building electrical systems, optional solar and EV charging. Properties save on energy costs by storing low-cost market electricity for peak usage periods.

Six partnerships are on record, tiered core and minor.
- HPF Kalajoki OycoreLehto Group acquired rights, contracts, and permits for a major battery storage project in Kalajoki through a business purchase agreement. HPF Kalajoki Oy transferred the project package enabling up to 30 MW battery storage implementation with potential for future capacity expansion.
- Desay BatterycoreCollaboration on 200 MWh grid-scale frequency regulation project. Desay Battery showcased their full portfolio including lithium-ion cells (100 Ah, 314 Ah, 587 Ah), sodium-ion cells, and solid-liquid state batteries at Smarter E Europe 2026. Lehto is working with Desay for battery supply and technology for Finnish energy storage projects.
- HANZA Mechanics Oulainen OyminorLehto sold its factory building and land lease right in Oulainen to HANZA Mechanics Oulainen Oy for EUR 4.7 million. Sale aimed to improve Lehto's financial position and support electricity storage business development. Majority of proceeds used to repay secured debts as part of restructuring plan.
- FingridcoreFinland's transmission system operator (TSO). Pielavesi battery park serves Fingrid's grid for balancing and frequency regulation. Energy storage systems help maintain grid stability and ensure operational reliability as renewable energy share grows.
- Savon VoimaminorRegional network operator in Savon Voima's network area where Pielavesi battery park is located. Network had sufficient capacity for efficient project implementation.
- Sunborn GroupminorHotel ship project currently under negotiation. Lehto plans to install battery systems for property owners to store cheap electricity from the exchange for use during peak pricing.

Lehto Group competitors and assessment
Company assessmentDirect peers
- Stem Inc: Stem (now part of Constellation) combines AI-driven energy-storage optimization with behind-the-meter and front-of-meter BESS assets for C&I customers and grid services — directly comparable to Lehto's AI-controlled BESS for both properties (<1 MW) and grid/markets (1–10 MW).
- Fluence Energy: Fluence is a global pure-play BESS IPP and software platform offering turnkey storage systems and the Fluence Mosaic OS optimizer for grid-services and wholesale trading — directly comparable to Lehto's AI-driven, 1–10 MW turnkey BESS targeting FCR/aFRR and arbitrage markets.
- Merus Power: Merus Power is a Finnish power-quality and BESS specialist headquartered in Tampere, supplying containerized BESS and energy-storage controls for grid-services and industrial customers — directly comparable as a domestic Finnish BESS developer/IPP targeting the same Fingrid ancillary markets.
- Alpiq: Alpiq is a Swiss energy company and active BESS IPP with a growing portfolio of grid-scale storage assets across Europe, including projects for ancillary services — directly comparable as a vertically integrated BESS developer/IPP with similar revenue stacking on European power markets.
- Cactos Energy: Cactos is a Finnish BESS-as-a-service startup deploying property and SME-scale batteries that trade in Finland's electricity markets — directly comparable to Lehto's property-side "<1 MW" leasing/product offering in the same Finnish market.
Broad incumbents
- Wärtsilä: Wärtsilä is a large Helsinki-listed energy-technology major with utility-scale BESS, grid services, and energy-storage optimization software, serving European TSOs and developers. Comparable as a broad incumbent in the same Finnish storage ecosystem where Lehto operates.
- Tesla Energy (Megapack): Tesla Energy supplies Megapack containerized BESS and the Autobidder trading platform to utilities and developers globally for ancillary services and arbitrage. Comparable as a broad incumbent in the utility-scale BESS IPP/turnkey category Lehto competes in.
- Rolls-Royce (Power Systems / mtu): Rolls-Royce Power Systems (mtu) supplies utility-scale containerized BESS (mtu EnergyPack) and integrates them with grid services, microgrids, and renewable assets. Comparable as a broad incumbent offering turnkey BESS in the same project-scale range (multi-MW) Lehto targets.
Regional players
- Statkraft: Statkraft is a Norwegian state-owned renewable IPP and the largest generator in the Nordics, increasingly developing BESS in Finland, Sweden, and Norway for grid balancing and trading. Comparable as a regional peer operating utility-scale BESS for Finnish and Nordic TSO markets, though from a Nordic rather than purely Finnish base.
Emerging players
- BrightLoop: BrightLoop is a Finnish energy-tech startup focused on behind-the-meter and front-of-meter energy storage, EV charging, and grid services for industrial and commercial customers — comparable as a Finnish emerging player in the same property-scale BESS segment Lehto serves.
