Regional Power Explorer

An interactive web map for exploring open-access electricity-sector data — generation mix, installed capacity, power plants, grid infrastructure, cross-border trade, electricity access, tariffs, and renewable-energy resources — at world, regional, and country level.

It is a pilot: not an official product of any institution, not endorsed by one, and parts of its content were drafted with AI assistance and have not been fact-checked. The tool aggregates and harmonises data from many open sources so that planners, analysts, and decision-makers can get a quick, sourced overview of a country's power system. It can be used to help populate inputs for the Electricity Planning Model (EPM), but it is a standalone data-exploration tool and is not limited to EPM.

Scope — what it is and isn't. The Regional Power Explorer aggregates and visualises already-published open data. It is not a power-system model, it does not run simulations or forecasts of its own, and the figures it shows are indicative: coverage and accuracy vary by region. Always cross-check against national statistics before using the data for planning or official purposes. See Limitations & Disclaimer.

Data sources

All layers, their sources, versions, update frequency, coverage, and a quality indicator are documented in the in-app Data Sources page (/about). Key sources include ENTSO-E, OpenStreetMap, the WRI Global Power Plant Database, Global Energy Monitor, the Global Solar Atlas, ERA5, Our World in Data, Ember, and national statistical offices.

Data licences include: OpenStreetMap (ODbL), WRI GPPD (CC BY 4.0), Global Energy Monitor (CC BY 4.0), World Bank Official Boundaries (CC BY 4.0), and others as listed on the Data Sources page.

Tech stack

Getting started

npm install
npm run dev        # local dev server (Vite, HMR)

npm run preview    # preview the production build
npm run lint       # ESLint

How data flows

data-source/        Raw inputs and pipeline intermediates (git-ignored — kept local, large)
   │  tools/ scripts fetch, clean, and harmonise
   ▼
public/data/        Curated, web-ready data served by the app (committed)

Only the curated, web-ready output under public/data/ is committed. Heavy raw inputs and caches under data-source/ are git-ignored (see .gitignore) and produced/refreshed by the scripts in tools/.

Project structure

Limitations & Disclaimer

• Data shown is indicative and aggregated from third-party open sources; coverage and accuracy vary by country and layer. Quality indicators are provided per source on the Data Sources page. Do not use as a sole basis for investment or policy decisions.
• Estimation methods (e.g. demand projections, capacity-factor derivation, wind-speed height correction) are documented on the Data Sources / Methods page; treat estimated layers accordingly.
• Parts of the content — in particular the country briefing notes held in public/data/notes/ — were drafted with AI language models and have not been verified or peer-reviewed. They may contain wrong figures or inaccurate statements on politically sensitive matters. Each note carries a line saying so; treat them as unverified drafts, not as sources.
• The boundaries, colours, denominations, and other information shown on any map do not imply any judgment concerning the legal status of any territory or the endorsement or acceptance of such boundaries.
• The findings and data presented here are for informational purposes only. They are not an official product of any institution, carry no institutional endorsement, and must not be attributed to any organisation or its members.
