Deliver more feasibility studies per engineer.
Indian clients are asking for more than a single-line solar proposal: open access versus captive, storage sizing, diesel displacement, green hydrogen pre-feasibility, cooling in the same study. Sympheny lets your team answer with rigorous, client-ready scenario comparisons in hours rather than weeks, so you take on more mandates without adding senior headcount.

Detailed Sankey energy flow. Every carrier, technology and storage element traced from supply to demand.
Trusted by consulting engineering teams worldwide
Used by engineering consultancies across Europe on feasibility, district energy and campus planning mandates. Delivered in India with model support and training from ORMAE, Bengaluru.
How Sympheny helps
Go beyond single-carrier studies
If you've worked in HOMER or Excel, you know the ceiling: electricity microgrids, one study at a time. Sympheny models power, cooling, heat, hydrogen and storage in one optimisation, so sector coupling shows up in the result instead of falling between two separate reports.
More scenarios, defensible recommendations
The MILP engine evaluates 50,000+ technology and capacity combinations per run, then puts every scenario on the same cost and CO₂ axes. Sensitivity runs on tariffs, demand and fuel prices are part of the workflow, which is what keeps a recommendation standing when the client pushes back.
Outputs the client's CFO can read
Sankey flows, Pareto charts and dashboards come straight from the model, in the browser, ready for a review call. Your engineers spend their hours on judgement, and your firm bills for analysis instead of chart formatting.
What changes for consulting and EPC teams
| Process | Before Sympheny | With Sympheny |
|---|---|---|
| Study setup | Each mandate starts from a fresh spreadsheet or a single-carrier HOMER model rebuilt by a senior engineer | Structured inputs and reusable workflows. Every study starts from a working baseline, with ORMAE on hand for model support |
| Scenario breadth | Two or three options per study, because each variant is manual rework | Pareto comparison across cost, CO₂ and technical constraints, with sensitivity runs included |
| Client delivery | Results translated by hand into slides before every review | Client-ready Sankey, Pareto and dashboard outputs from the same model that ran the optimisation |
| Winning the next mandate | Capability is hard to demonstrate beyond references and CVs | Show a live scenario comparison in the pitch. Buyers can challenge the numbers, which is exactly what builds trust |
The sensitivity analysis is what makes a recommendation stick when the client pushes back.
“Sympheny supports our strategic energy planning in an ideal way. The flexibility is extremely convincing and the sensitivity analysis provides security in finding solutions.”

Proven on European consulting projects. Delivered in India with ORMAE.
Sympheny has not run an Indian reference project yet, and we won't pretend otherwise. What we can show is how consulting teams in Europe use the same workflow on live feasibility work, with local model support from ORMAE in Bengaluru.
Green hydrogen production and sector coupling
Technical proof: Green hydrogen and sector-coupling variants optimised
Business outcome: 60% CO2 reduction and up to 26% lower life-cycle costs identified.
Strategic energy concept for the Insel-Holligen district
Technical proof: 30+ price and demand scenarios tested
Business outcome: Infrastructure investment stress-tested before commitment.
Residential energy concept for a new housing quarter
Technical proof: 16 buildings, 3 supply variants on the same Pareto front
Business outcome: Groundwater heat pumps win once cost, CO2 and autarky are weighed together.
