Services
Your battery, from the land to commissioning.
We find the right land, size the battery, structure the financing and build it. For industrial and commercial sites and grids in Switzerland.
One partner
Total contractor: engineering and construction, together
TC
Total contractor
We combine the engineering firm and the general contractor. We study, design and build your battery under a single contract, with an agreed price and schedule, from the land to commissioning.
ING
Engineering firm
We support you under mandate, SIA phase by SIA phase. You remain the owner and choose your contractors.
- Feasibility and land selection
- Sizing and business plan
- Permit file and tender
- Site supervision
GC
General contractor
We build the battery turnkey on the basis of an already designed project: one contract, an agreed price and deadline, up to commissioning.
- A single point of contact
- Turnkey construction
- Supplier and deadline management
- Commissioning
Both services remain available separately: engineering firm only, on a mandate SIA phase by SIA phase (you remain the project owner and choose your contractors), or general contractor only, to build a project that has already been designed.
Phase by phase
Our services along the SIA phases
Each phase has its tool. You always see where the project stands and what comes next.
SIA 1
Land Qualifier: is this land worth it?
Before any study, we screen the land: owner, zoning, plot shape, distance to housing, contamination, natural hazards, rent and distance to the electrical station. One knock-out criterion is enough to drop it. If everything is green, we meet the owner.

SIA 2
Feasibility study
For a selected plot, we check that the project holds: agreement with the owner, grid connection request to the network operator, battery layout and first cost estimate.
SIA 3
Optimal BESS Sizer: the right size and the business plan
The Sizer simulates your site in 15-minute steps with your network operator’s real tariffs and tests every battery size. You get the optimal size and the business plan: CAPEX, revenue, NPV, IRR and payback. On this basis we prepare the preliminary design, the project and the permit file.

Value stacking: one asset, two sources of value
The Sizer adds up what the battery saves the site (P1) and what it earns through third parties (P2), always compared with the same site without a battery. Only what the battery changes is counted.
P1 · Site services
Solar self-consumption, peak / off-peak arbitrage and shaving of the power peak.
Example: the monthly peak drops from 900 to 700 kW. With a power tariff of CHF 10/kW/month: 200 kW × 10 × 12 = CHF 24,000/year.
P2 · Third-party services
Capacity added beyond the site’s needs is reserved by an aggregator or trader (reserves, arbitrage). The owner receives a share of the gains.
Example: 0.5 MW reserved × CHF 120,000/MW/year × 82 % owner share = CHF 49,200/year.
Annual revenue = P1 + P2 = 24,000 + 49,200 = CHF 73,200/year
Simplified example, energy savings not included. Method: the Sizer first finds the best battery for the site (P1), freezes it, then tests each P2 increment on top. Each block has its own NPV: the battery is only enlarged for third parties if it pays off.
Preparing the study: downloads
To start a study we need the site’s data. The checklist lists everything to collect: electricity bill, grid connection, PV systems, load curves. The sample report shows what you receive at the end.

Tender and financing
We prepare the tender, compare the offers and propose the award. In parallel, we structure the financing of the battery:
EquityYou finance it and keep all the gains.
Bank loan or leasingYou spread the investment.
Third-party investorAn investor finances the battery; you share the gains.
Revenue contractAn aggregator secures part of the flexibility revenue.
SIA 51–52
Construction: reshaping the build with BIM
We reshape the construction phase with BIM: every step of the site is modelled and simulated day by day (deliveries, assembly, people on site). The shared model makes exchanges between suppliers and service providers easier. We manage suppliers, schedule and deadlines, from detailed design (SIA 51) to construction (SIA 52).
