From project inputs to defensible energy scenarios in one workflow
See how engineering, utility, and public-sector teams use Sympheny to bring inputs together, optimise across thousands of options, and deliver decisions stakeholders can stand behind.

Scenario setup, optimisation, and reporting in one workflow.
A four-step workflow, from project inputs to client-ready outputs.
The same platform takes you from raw project inputs to optimised scenarios to a report you can hand to a client — without rebuilding the model in between.
Bring project inputs together
Pull demand profiles, site characteristics, tariffs, and benchmarks into a single project. Locally relevant assumptions are configured per region, so teams start from a defensible baseline instead of stitching together spreadsheets.
Build and optimise scenarios
Define the technologies and constraints that matter, then let the multi-objective optimiser search across 50,000+ technology and capacity combinations to find the architectures that meet your cost, emissions, and space targets.
Compare trade-offs
Put every optimised scenario on a Pareto Front across cost and CO₂. See the cheapest option, the lowest-carbon option, and the trade-offs in between — so the recommendation holds up to scrutiny.
Share client-ready outputs
Sankey diagrams, Pareto comparisons, technology investments, capacities and monthly energy flow all live in the same interactive dashboard. Apply filters, download the graphs and their data, and print straight from the browser. The project lives on as a digital twin of your site — re-run as inputs evolve, without rebuilding the model.
Optimise the system, not isolated components.
A heat network, PV system, storage asset, or grid connection may look optimal alone while weakening the wider energy concept. Sympheny compares integrated scenarios so teams can see system-level trade-offs before decisions are locked in.
Client-ready results, built from your inputs.
How different teams use the workflow
The same workflow flexes to the projects and decisions each team is responsible for.
Engineering firms
Move from fragmented inputs to defensible scenarios faster, and free senior engineers from manual data prep to focus on the engineering judgement clients pay for.
Explore the workflowUtilities
Plan across networks, tariffs, and long-term investment horizons with scenarios that can support infrastructure decisions and regulatory conversations.

Build city-wide energy strategies and district plans with a process that fits public-sector timelines and produces reporting outputs stakeholders trust.
Explore the workflowDevelopers & Industrial Sites
Compare site energy concepts across CAPEX, OPEX, CO₂, grid constraints, and phasing before major infrastructure decisions.
Explore the workflowThe workflow at the scale planners actually face.
Green hydrogen produced on-site at a cost comparable to diesel — life-cycle costs cut 26% versus the fossil baseline.
Read case studyThree city-wide scenarios confirmed a CO₂-free energy supply is achievable at similar life cycle costs to today's fossil-based system.
