BESS applications
BESS solutions to reduce costs and strengthen
Each system is sized according to the load profile, operating constraints and the services it must provide throughout its life cycle.
Peak shaving01 / Industry
01
Peak shaving
+Reduces demand peaks through automatic BESS discharge, lowering charges associated with capacity and maximum demand.
02
Load shifting
+Stores energy during lower-cost periods and uses it during hours with greater economic value.
03
Energy backup
+Maintains critical loads and processes during outages or supply variations, with islanded operation when the architecture allows it.
04
Capacity expansion
+Provides additional power to add new loads, expand production and defer electrical infrastructure investments.

Financial structures
The right technology with the
OPSLAG can structure the project around investment objectives, cash flow, tax benefits and operating horizon.
01 · Ownership
Direct purchase
The client adds the equipment to its assets and receives all savings generated by the project.
- System ownership and control from acquisition
- Higher cumulative economic return over the asset’s useful life
- Access to applicable tax and depreciation benefits
02 · Flexibility
Operating lease
BESS implementation with no down payment or initial cash outlay. Lease payments are structured below the estimated energy savings, allowing the project to pay for itself with the savings it generates.
- No initial investment
- Positive net cash flow from the start of operations
- Preserves the client’s liquidity and financial capacity
03 · Financing
Finance lease
Financed acquisition of the system through a down payment and periodic payments. Financing is structured so that each payment remains below the savings generated while the client adds the asset and can take advantage of applicable tax benefits.
- The system is paid for through the savings it generates
- Asset ownership at the end of the contractual term
- Potential to apply depreciation and tax benefits associated with the investment
