Battery storage for municipal utilities:

Act now. Invest safely. Strengthen returns.

Start a free quick check

Battery Energy Storage Systems (BESS) are an opportunity for municipal utilities to relieve the strain on grids, generate attractive market revenues and at the same time secure predictable cash flows.

Why large-scale battery storage systems are relevant now:

Yield and bankability

  • Attractive returns with a short amortization period
  • Fixed remuneration/tolling → low-risk and financeable

Timing and market opportunities

  • Grid fee exemption for commissioning until 2029
  • High revenue expectations in the coming years (balancing energy, day-ahead/intraday)

Holistic with Uniper

  • Feasibility study as a clear basis for decision-making ("from A to B")
  • Grid load profile optimization possible
  • Sovereignty: municipal utilities decide who builds storage facilities, where they are located and how they are operated

5 steps to your energy storage with Uniper:

1

Start: Feasibility study

Location, technology and business case check incl. scenarios and network analysis - well-founded, transparent, ready for a decision. We answer your key questions: Is storage worthwhile? Which technology is right? What does the economic viability look like?

2

Customized remuneration models

Fixed (low-risk/bankable) or risk-adjusted (return-oriented) - depending on the return/risk profile. Once the study has been completed, we will submit a specific tolling offer to you.

3

Asset construction

We take care of supplier management and coordinate the entire construction process – from selecting suitable partners to implementing professional engineering, procurement, and construction (EPC) support.

4

Operation and marketing

  • 24/7 monitoring and reporting: Real-time monitoring, revenue forecasting and compliance.
  • Cross-market marketing: Regulating energy, day-ahead, intraday—we maximize your revenues. In addition, grid-friendly operating modes (e.g., peak shaving) can be supplemented.

5

Strong partnership

  • You retain control: you are in control of site selection, supplier selection and project design.
  • We accompany you from analysis to operational optimization - transparently, in partnership and goal-oriented.
