Energy Planning Without Barriers
From Regional Vision to National Action
OpenARC is the first unified global energy optimisation platform — production-ready infrastructure for market and network analysis, now extended to 122 countries across CAREC, the EU and Africa.
One platform, end to end
From an immersive global atlas to bankable cost-benefit, long-term expansion, physical network studies, and a local-first AI assistant — every step built on one auditable, reproducible foundation.
Mission Control — Immersive Energy Atlas
A 3D world view of the global power system. Every plant, every transmission line, every cross-border flow — visible, queryable, and linked back to the model.
- 41,625 power plants and 580,000+ HV lines
- 120 countries with sub-national grids
- Animated cross-border flow arcs
- Open-Meteo / ERA5 weather integration
“From a boardroom narrative to a ground-truth network, in two clicks.”
Build your layer of market intelligence
Add your own analytical layers on top of real data — directly on the live atlas.
Track progress in real time
Watch optimisation runs and results update live as the model solves.
Let OpenARC guide you through key market intelligence
A guided walkthrough that surfaces the insights that matter most across the energy atlas.
Data Marketplace — Country-Owned, Version-Controlled
Each country owns its own data templates. Every change is logged, diffable, and reversible. Sovereignty is built in, not bolted on.
- 7-sheet country template (generators, storage, transmission, demand, VRE…)
- Visual side-by-side compare highlights changed cells
- Full audit log per template
- Reversible to any prior version
“Inputs you own. Changes you can prove. Versions you can revert.”
Cost-Benefit Assessment
Bankable project economics computed from the same dispatch model. TYNDP-aligned PINT / TOOT methodology, five indicators, hourly welfare attribution.
- PINT & TOOT — auto-pairs scenarios and runs both
- B1 Socioeconomic Welfare (SEW)
- B2 CO₂ societal premium (SCC €20–100/t)
- B3 Renewable integration (GWh)
“Every benefit traced back to the dispatch hour that produced it.”
Long-Term Capacity Expansion
Co-optimise new build across generators, storage, and transmission under budget caps and renewable targets. The same LP engine; longer horizon, more decision variables.
- Solar PV, wind onshore/offshore, thermal, BESS 4h–24h, new lines
- Total budget cap and renewable energy target levers
- Optimal MW per candidate and plant-by-plant build plan
- One click from scenario to operational run
“From scenario to investment programme in a single workflow.”
Validating the Physical Grid
From economic dispatch to the physics of the network. OpenARC rebuilds a power-flow network from the model's own dispatch, proves it reproduces those flows, then runs a full grid-study stack.
- DC load flow, I²R losses by country, AC voltage profiles
- N-1 contingency security (LODF watch-list)
- PTDF sensitivity + flow decomposition, dNTC at a border
- Rotor-angle stability and short-circuit studies
“The same network the market dispatched, now stress-tested as physical hardware.”
AI Assistant — Conversational Analytics, Local-First
Ask the platform in plain English. 15 analytical tools wired into a streaming chat. Runs on a local model — no data leaves your premises.
Ask in plain English
“Loadshed in South Africa, scenario 17?” · “Compare scenarios 12 and 18.” · “List Germany data templates.”
15 analytical tools
Query loadshed, prices, emissions and interconnector flows; compare runs; create and run scenarios — all from chat.
Local LLM, streaming UX
Served on-premise with Server-Sent Events for live tokens and visible tool-call traces. No cloud dependency.
Every step logged
Full conversation history, per-message tool invocations, a reproducible result trail, and role-based access.
“A research analyst on call, 24/7, inside your firewall.”
What the Platform Answers Today
Concrete policy and investment questions answered in seconds to minutes. Every question becomes a scenario with full results.
What is the least-cost generation mix for the CAREC region?
What is the economic value of upgrading the Kazakhstan–China interconnector by 500 MW?
How does a 5 GW solar expansion in Uzbekistan change marginal prices across the region?
What happens to supply security in Afghanistan if Pakistan's demand doubles?
How does a carbon price of €50/tCO₂ shift the mix from coal to gas and renewables?
How does an N-1 contingency on a key cross-border line reshape regional flows?
