Plan the net-zero pathway your board, regulator, and customers can stand behind.
Net-zero by 2050 means real CAPEX decisions in this planning cycle — district heating growth, grid reinforcement, sector coupling, and a generation mix that holds up under regulator and customer scrutiny. Sympheny gives utility planning teams one model to compare those pathways side by side, with cost, CO₂, and supply-security trade-offs visible from day one.

Hourly heating demand with load-duration curve — full-year resolution for a 1,000 m² residential building.
Trusted by utility and grid planning teams
Used by Swiss and European utilities to plan district heating expansion, generation strategy, and city-wide supply pathways toward 2050.
How Sympheny helps
One model for every supply pathway
Compare district heating, electrification, sector coupling, and generation mix scenarios on the same baseline — not as separate studies stitched together at the end.
CAPEX and CO₂ trade-offs visible early
Quantify the investment implications of each pathway before committing — so the board, the regulator, and the customer base see the same evidence base.
A planning asset, not a one-off study
When tariffs, demand forecasts, or policy assumptions move, re-run scenarios in the same workflow instead of restarting from a blank sheet.
What changes for utilities and grid planners
| Process | Before Sympheny | With Sympheny |
|---|---|---|
| Network and supply planning | Each district, network, and supply option lives in its own study — hard to compare, harder to defend | One structured model compares long-term supply, DH and grid scenarios side by side on the same baseline |
| Infrastructure investment case | CAPEX, OPEX and CO₂ trade-offs are difficult to quantify before the board commits | Scenario outputs make the life-cycle cost and emissions implications of each pathway visible early |
| Regulatory and market change | Tariff, demand, or policy shifts trigger weeks of manual rework | Update assumptions once and re-run scenarios in the same workflow — the planning asset evolves with the system |
| Net-zero roadmap | A static study delivered to the board and outdated by the next planning cycle | A living roadmap the team owns, re-runs, and uses to brief the regulator and customers |

City-wide energy supply strategy toward 2050
Technical proof: 3.2 M m2 energy reference area, three time horizons modelled
Business outcome: CO2-free 2035 supply confirmed at similar life-cycle cost.
Optimal expansion strategy for a district heating network
Technical proof: Five network segments included in the optimal design
Business outcome: Three of four expansion scenarios confirmed profitable.
Solar development strategy for the Port of Switzerland
Technical proof: 16 variants across four strategies optimised
Business outcome: Up to 20-25% cost reduction identified; lowest-risk path confirmed.
