Battery Storage for Swiss Industry, Logistics & Sites 🇨🇭

NRG Solutions works from 1 MW of grid connection capacity. Suitable sites are industrial locations, commercial estates, energy supply companies and operators of larger infrastructures with a grid connection at grid level 5 (medium voltage) and annual energy consumption above 1 GWh. Typical applications include self-consumption optimization, where PV surplus is stored and time-shifted for later use, and peak shaving, which can reduce demand charges by 20 to 50 percent. Additional use cases include grid relief, security of supply with millisecond response times, and marketing flexibility through ancillary services (SDL) for Swissgrid. Based on project data from ten NRG Solutions BESS projects in Switzerland with a combined capacity exceeding 150 MWh, combining multiple use cases significantly improves the business case. For example, the SABAG Rothenburg project with 3.45 MW and 5 MWh is designed for both peak shaving and SDL market participation on the Swissgrid market.

A BESS is economically viable when load profiles, grid connection conditions, tariffs, and operating strategy are carefully coordinated. The decisive factor is not just battery size, but the combination of technical design, intelligent energy management through a capable EMS, and integration with relevant markets such as the Swissgrid SDL market. NRG Solutions evaluates every project rigorously using DCF analysis, sensitivity analyses, NPV, and IRR rather than generic ROI promises. NRG Solutions works from 1 MW of grid connection capacity; the most economically attractive sites are at grid level 5 (medium voltage), with annual energy consumption above 1 GWh and pronounced load peaks in the demand profile. Modern lithium-ion batteries achieve over 6,000 cycles and a lifespan exceeding 15 years, which further strengthens long-term viability. The complete evaluation process from load profile analysis to finished financial modeling typically takes just a few weeks and is non-binding for the customer.

The energy management system is the core of every BESS, controlling the battery storage in real time using intelligent algorithms. It optimizes energy flows at the site by deciding when to store, discharge, or market energy based on load forecasts, current tariffs, and market prices. The NRG Solutions EMS enables simultaneous use of multiple use cases such as peak shaving, self-consumption optimization, and ancillary services (SDL) for Swissgrid. Unlike static control systems, the EMS adapts dynamically to changing conditions and maximizes total revenue across the entire battery lifespan of over 15 years and 6,000 cycles. Through the NRG Solutions own balance group, SDL revenues are marketed directly on the Swissgrid market. The system also provides transparent reporting and 24/7 monitoring, ensuring performance is traceable at all times. Response time is in the millisecond range, which is particularly critical for primary control reserve and frequency regulation applications.

Yes, modern battery storage systems can serve multiple use cases in parallel, and this is precisely where a key economic advantage over single-application systems lies. This requires clean prioritization of applications and a powerful energy management system (EMS) that accounts for technical, economic, and regulatory conditions in real time. For example, a BESS can perform peak shaving during the day, reducing demand charges by 20 to 50 percent, while simultaneously providing balancing energy on the Swissgrid SDL markets and generating attractive additional revenue. During low-load periods, the storage can be used for self-consumption optimization or energy arbitrage. The NRG Solutions proprietary EMS manages this prioritization fully automatically, with marketing through the balance group NRG Optimization AG is building up, ensuring the battery with its 6,000-plus cycles and 15-year lifespan is utilized optimally and revenues are maximized across all streams.

A BESS project with NRG Solutions follows seven clearly defined steps and typically takes 9 to 18 months from initial analysis to commissioning. In the pre- and feasibility study we analyze consumption (15-minute interval data), generation, tariffs and the available grid connection capacity, size the storage system and assess its economic viability with NPV and IRR. This leads to a project concept with a project-specific offer that aligns storage, grid connection and infrastructure. We then agree on the investment model: you invest yourself, or we take on the financing under contracting. As part of EPCM we handle detailed planning, permits, procurement and project management and steer construction and installation with our implementation partners. After functional tests, commissioning and documented handover, we support technical operation with monitoring, maintenance and service. NRG Optimization AG manages the commercial operation of the storage system and continuously coordinates self-consumption, peak shaving, arbitrage and ancillary services.

NRG Solutions pursues a fully integrated approach that fundamentally differs from other providers in the Swiss market. From initial load profile analysis and BESS hardware through financing to ongoing operations and active market participation, we take responsibility for the entire system from a single source. Central to our differentiation are our proprietary energy management system (EMS) and our own balance group, which enable direct SDL participation on the Swissgrid market without intermediaries. This eliminates complex interfaces between multiple service providers, reducing risk and significantly increasing predictability. With four systems in operation and six under implementation (together over 150 MWh), we continuously refine our operating strategies. NRG Solutions also offers flexible financing models, including full-service without any customer capital investment, and evaluates every project transparently with NPV and IRR rather than generic ROI promises.

The size depends on the load profile, target applications and grid connection, not on a fixed rule of thumb. NRG Solutions works from 1 MW of grid connection capacity; the systems are modular and scalable up to large-scale storage above 40 MWh. What matters is sizing power (kW) and capacity (kWh) based on 15-minute load data: for peak shaving the available power for peak capping is decisive, for self-consumption optimisation the capacity to store PV surplus. The reference projects range from 215 kWh (Hofgenuss Rain, in operation) to 60 MWh (under implementation).
