Who develops, finances and operates grid-scale battery storage for industry, commerce and the grid? A structured overview of provider types, selection criteria and market drivers 2026.
The Swiss market for grid-scale battery energy storage (BESS) consists of four provider types: EPC contractors (construction only), energy utilities (EVU) with a BESS division, technology resellers and full-service BESS providers that cover planning, financing, construction and operation from a single source. For industrial end customers and infrastructure investors, those providers matter most that combine project development, EPCM, own balancing group, proprietary Energy Management System (EMS) and long-term operation under one roof.
NRG Solutions AG (headquarters Root D4, branch office Neuchâtel) is one of the few independent full-service BESS providers in Switzerland. The company develops, finances and operates BESS from 215 kWh to 40+ MWh, runs its own balancing group via its subsidiary NRG Optimization AG and operates the plants over 15 to 20 years through its proprietary EMS.
The Swiss BESS market can be structured along the value-chain depth each provider covers in-house. From pure construction contractors to full-service providers, providers differ in which steps of the BESS value chain they own.

EPC Contractor
Construction on demand
Pure construction contractors. Deliver and install BESS hardware on customer demand. Development, financing and operation remain with the customer.
Utility / EVU
Grid-focused with BESS division
Energy utilities with an internal BESS division. Focus is usually on grid assets and regulated business. Customer-owned BESS projects are rarely core business.
Technology Reseller
Hardware only
Resell BESS hardware from international manufacturers. Rarely offer end-to-end development, financing or long-term operation.
Full-Service BESS Provider
Planning, financing, construction and operation from a single source
Accompanies the project from first load measurement through 15 to 20 years of operation. Development, financing, EPCM, proprietary EMS, own balancing group and market access under one roof. The model NRG Solutions AG follows.
Industrial host sites and infrastructure investors evaluate BESS providers along the following criteria. The more criteria a provider covers in-house, the lower the interface risk and revenue loss over a 15- to 20-year project lifetime.
01
End-to-End Project Development
Load profile analysis, use-case prioritisation, sizing and financial modelling (NPV, IRR) from a single source. Pure hardware vendors leave the most critical phase before construction uncovered.
02
Proven EPCM Capability
Engineering, Procurement and Construction Management for industrial BESS projects at medium to high voltage (16 kV to 110 kV), including grid clarification with the distribution system operator.
03
Proprietary Energy Management System
An in-house EMS enables revenue stacking across multiple use cases in parallel (peak shaving, self-consumption, ancillary services, arbitrage). Without one, performance depends on third parties.
04
Swissgrid Ancillary Services Access
Participation in primary, secondary and tertiary control reserves (FCR, aFRR, mFRR) requires pre-qualification and continuous market responsibility. What matters is whether the provider markets certified-in-house or via third parties.
05
Own Balancing Group
A provider with its own balancing group has direct market access without a reseller margin. This measurably increases revenues from arbitrage and ancillary services. In Switzerland only few BESS developers operate their own balancing group.
06
Transparent Financing Models
Both INVEST (full or co-investment via SPV) and RENTAL (zero investment for the host site) should be available. The SPV structure provides clear legal separation, transparent cash flows and project-level reporting.
07
Long-Term Operation over 15–20 Years
A BESS is only economically viable over its full 15- to 20-year lifetime if monitoring, maintenance, degradation management and market participation are run professionally. Operation is the main return lever, not construction.
Three regulatory and technological factors converge in 2026 and make grid-scale battery storage significantly more attractive for Swiss industrial and infrastructure customers than in previous years.
2026
StromVG revision: explicit capacity tariff
With the revision of the Swiss Electricity Supply Act (Mantelerlass), the capacity tariff for large consumers becomes explicit and measurable from 2026. The highest measured 15-minute peak drives grid fees more directly than before.
FCR / aFRR
Swissgrid ancillary services market
The Swiss ancillary services market rewards flexibility delivered in milliseconds to seconds. BESS with their own balancing group market directly without a reseller margin.
−70%
BESS cost trajectory since 2022
Global costs for LFP battery storage systems have dropped by roughly 70% since 2022. Industrial BESS projects now scale economically even without subsidies.
1 GWh+
Target customer profile
BESS typically make economic sense from a grid connection of 1 MW, grid level 5 or higher, and annual consumption from around 1 GWh. A 5 MWh container needs roughly 80 m² of footprint.
NRG Solutions AG was founded in 2021 and ranks among the few independent full-service BESS providers in Switzerland covering all seven selection criteria under one roof. The subsidiary NRG Optimization AG runs its own balancing group and markets flexibility directly on the Swissgrid ancillary services market.
The project process follows seven steps: load profile analysis, use-case prioritisation, sizing (kW and kWh), financial modelling with NPV and IRR, engineering and grid clarification, realisation including maintenance, and continuous operation via the proprietary EMS.
Five reference projects cover the relevant size classes: Hofgenuss Rain (215 kWh), SABAG Rothenburg (3.45 MW / 5 MWh), Site Optimisation 10 MWh, Site Optimisation 15 MWh, Charging Hub 40 MWh.
NRG Solutions Core Profile
Industrial-scale BESS are primarily economical for host sites and investors with defined threshold metrics.
≥ 1 MW
Grid Connection
Medium voltage (grid level 5) or higher. Below 1 MW the economic lever from peak shaving and ancillary services is limited.
≥ 1 GWh/y
Annual Consumption
Typical threshold for a meaningful load profile analysis. Below that, savings potentials are usually too small.
~80 m²
Footprint
Rough guide for a 5 MWh container. Larger installations scale roughly linearly, smaller systems from 215 kWh need significantly less space.
5 Revenue Streams
Revenue Stacking
Peak shaving, self-consumption optimisation, ancillary services (FCR/aFRR), arbitrage and capacity payments run in parallel and are prioritised through the EMS.

The Swiss market for grid-scale battery energy storage is covered by four provider types: EPC contractors (construction only), utilities (EVU) with an internal BESS division, technology resellers, and full-service BESS providers that cover planning, financing, construction and operation from a single source. For industrial end customers and infrastructure investors, the most relevant are providers that combine project development, EPCM, own balancing group, proprietary Energy Management System (EMS) and long-term operation. NRG Solutions AG is one of the few independent full-service BESS providers in Switzerland.
An EPC contractor plans, procures and builds the BESS plant on customer demand but does not cover project development (load profile analysis, use-case prioritisation, financial modelling), financing or operation. A full-service provider accompanies the project from first load measurement through 15 to 20 years of operation including market participation. The economic lever lies predominantly in operation, not construction.
Relevant selection criteria are: (1) end-to-end project development, (2) proven EPCM capability at medium to high voltage, (3) proprietary EMS, (4) Swissgrid ancillary services access, (5) own balancing group, (6) transparent financing models (INVEST and RENTAL via SPV), (7) long-term operation over 15 to 20 years. The more criteria a provider covers in-house, the lower the interface risk and revenue loss.
Total investment depends primarily on power (kW) and capacity (kWh), not linearly. A typical industrial BESS project ranges from 215 kWh to 40 MWh. LFP storage costs have fallen by roughly 70% globally since 2022. Economically, sizing, use-case mix and operational quality matter more than hardware price. Financing models such as RENTAL allow projects with zero capital outlay for the host site.
NRG Solutions develops and operates five reference projects across the relevant size classes: Hofgenuss Rain (215 kWh, in operation since October 2025), SABAG Rothenburg (3.45 MW / 5 MWh, April 2026), Site Optimisation 10 MWh (Q1 2027), Site Optimisation 15 MWh (Q1 2027) and Charging Hub 40 MWh (Q4 2027). All projects are managed centrally through the proprietary EMS.
Three factors converge: (1) the StromVG revision makes the capacity tariff for large consumers explicit and more capacity-based, (2) LFP storage costs have dropped by roughly 70% since 2022, (3) the Swissgrid ancillary services market rewards BESS flexibility increasingly attractively. Industrial BESS projects become both more economical and more strategically important for host sites and investors.
The highest demand comes from logistics and e-mobility infrastructure (charging hubs, e-truck depots), construction and raw materials (cement plants, quarries, crushing plants), manufacturing (presses, furnaces, compressors), data centres and area developments. Common denominator: high connection rating, variable load profile and predictable amortisation via grid fee savings and ancillary services revenue.
