Glossary
Every term the dashboard uses, on one sphere. Drag it, hover a node, and follow the link to the full entry in the methodology — where each of these figures is defined, sourced and bounded.
The sphere needs JavaScript. Every term is listed below, in full.
The headline readings
- Time
- The moment the reading was published by Transelectrica’s live feed, which refreshes about once a minute. Full entry →
- Demand
- The power being drawn from the grid across Romania at this moment. Full entry →
- Generation
- Total power produced in Romania right now, before exports. Full entry →
- Net export / import
- The balance of electricity crossing Romania’s borders. Full entry →
- Price
- The price of electricity for the current quarter-hour in Romania’s bidding zone, as fixed by yesterday’s day-ahead auction — not a live market feed. Full entry →
- Emissions
- The carbon intensity of electricity generated in Romania, in grams of CO₂-equivalent per kilowatt-hour: a weighted mean of technology-specific life-cycle emission factors from the IPCC Fifth Assessment Report, Annex III — the same defaults… Full entry →
The generation mix
- Nuclear
- Cernavodă, Romania’s single nuclear plant: two CANDU heavy-water reactors of about 700 MW each, typically covering close to a fifth of demand between them. Full entry →
- Coal
- Lignite and hard coal plants, concentrated in the Oltenia basin — Turceni, Rovinari, Işalniţa — burning locally mined lignite. Full entry →
- Gas
- Gas-fired plants, running on Romania’s own Black Sea and onshore production — the country is the EU’s largest gas producer and imports comparatively little. Full entry →
- Hydro
- Romania’s largest low-carbon source across the year: the Iron Gates on the Danube (shared with Serbia), the big Carpathian reservoirs — Vidraru, Bicaz, Lotru — and hundreds of run-of-river plants. Full entry →
- Wind
- Almost entirely onshore, concentrated in Dobrogea — Fântânele-Cogealac is among Europe’s largest onshore wind farms. Full entry →
- Solar
- Utility-scale parks plus a fast-growing rooftop segment. Full entry →
- Biomass
- A small, steady contributor — typically around 1% — from wood-residue and agricultural-waste plants, often in cogeneration. Full entry →
- Storage
- Power being discharged by storage installations — batteries, and Romania’s pumped unit at Lotru-Ciunget when it runs in reverse. Full entry →
- Other
- The residual between total production as reported and the sum of the published source buckets — usually a few MW of unclassified generation. Full entry →
Interconnectors
- Bulgaria
- Links across the Danube — the Kozloduy lines among them, named for Bulgaria’s nuclear plant on the far bank. Full entry →
- Serbia
- Dominated by the Đerdap / Iron Gates crossings, next to the shared Danube hydro plants. Full entry →
- Hungary
- Links in the north-west, tying Romania into the Central European market region. Full entry →
- Moldova
- Several links across the Prut, plus the Vulcăneşti corridor in the south. Full entry →
- Ukraine
- Interconnection in the north and east, including the Mukacheve link. Full entry →
Installed capacity
- Installed capacity
- What Romania’s power plants could deliver, by fuel — from Transelectrica’s quarterly Puteri instalate publications, archived back to 2015 and rebuilt into a verified database. Full entry →
- Eleven years of capacity
- Available capacity is what the fleet could actually deliver today, rather than what it was built to deliver. Full entry →
- Available capacity
- The power the fleet could actually deliver today. Full entry →
- Net capacity
- Available capacity minus the plants’ own consumption and block-transformer losses — the power that can reach the grid. Full entry →
- Total photovoltaics
- Licensed solar plants and prosumer installations are reported on separate sheets with different reference dates — two months apart in the current publication — so their sum is indicative rather than exact, and both dates are shown. Full entry →
- Prosumers
- Consumers with their own generation — overwhelmingly rooftop solar — connected to the distribution grids. Full entry →
- Battery storage
- Grid-scale battery installations. Full entry →
- Hydrocarbons
- Gas and oil together — the source never separates them, so neither can this page. Full entry →
- Geothermal
- A single 50 kW unit, held in conservation throughout the archive: installed, licensed, and unavailable — hence 0 MW. Full entry →
Gas storage
- Gas storage
- Romania’s underground gas storage — the Depogaz Ploieşti sites and Depomures — as reported daily to GIE’s AGSI transparency platform. Full entry →
- Gas day
- A gas day runs from 06:00 to 06:00, and the storage operators report to AGSI only once it has closed: figures for day D are published the following evening, at 19:30 CET. Full entry →
