Linked Energie-Atlas

Bavarian per-Gemeinde energy data as content-negotiated Linked Data — one resource per municipality, keyed by its AGS (Amtlicher Gemeindeschlüssel), accreting metrics from several Energie-Atlas Bayern layers. The PV-Potenzial auf Dachflächen layer is just the first — biomass and more follow (see Coverage).

Coverage

Served now

Rooftop-PV & solar-thermal potential, ground-mounted (Freiflächen) PV potential, biomass (biogas potential, installed biomass electricity, share), the renewable share of electricity consumption, and the renewable generation mix by carrier — all merged onto one area/{ags} resource per Gemeinde (below).

Harvested from the Energie-Atlas, conversion pending

Wood/KUP biomass potentials, Wärmenetze, and the heat-demand layer (a targeted harvest away). Same source, each merged in as it is mapped to RDF.

Join, don't duplicate

Per-installation layers (individual PV/KWK/biomass/geothermal plants) overlap linked-mastr — reach them by the shared AGS, not here.

The compelling figure is the Ausbaulücke — how little of the available rooftop potential is built out yet (Ausbaugrad = installed / potential).

What each resource carries

A vocab:AreaPotential thing per Gemeinde, accreting the metrics of each merged layer:

vocab:pvPotentialCapacityMWp / vocab:pvPotentialYieldMWh

Installable rooftop-PV capacity (MWp) and expected annual yield (MWh/a) — installierbare Leistung / Jahresertrag.

vocab:installedCapacityMWp / vocab:installationCount

Already-installed PV capacity (MWp) and number of systems — installierte Leistung / Anzahl Anlagen.

vocab:remainingPotentialMWp / vocab:developmentDegreePct

Unrealised headroom (MWp) and build-out degree (%) — verbleibendes Potenzial / Ausbaugrad, the Ausbaulücke.

vocab:solarThermalPotentialMWh

Solar-thermal (hot-water) potential, MWh/a — Solarthermie-Potenzial.

vocab:shareResidentialPct / sharePublicPct / shareCommercePct / shareIndustryPct / shareUnheatedPct / shareOtherPct

Share of the potential by building use, incl. Gewerbe/Handel & Industrie — Gebäudenutzung.

vocab:heritageSharePct

Share on heritage-protected buildings (%) — Anteil denkmalgeschützt.

vocab:biogasPotentialElectricKWhPerYear / vocab:biogasPotentialMethaneM3PerYear

Technical biogas potential — electric (kWh/a) and methane (m³ CH₄/a) — Biogaspotenzial.

vocab:biomassInstalledCapacityMW / vocab:biomassElectricityProductionMWh / vocab:biomassInstallationCount

Installed biomass-electricity capacity (MW, EEG), 2024 production (MWh), and plant count — Strom aus Biomasse.

vocab:biomassElectricitySharePct

Share of biomass in local electricity consumption (%) — Anteil Biomasse am Stromverbrauch.

vocab:renewableElectricitySharePct / vocab:electricityConsumptionMWhPerYear

Renewable share of local electricity consumption (%) and total consumption (MWh/a) — Anteil EE am Stromverbrauch.

vocab:population / vocab:areaKm2

Gemeinde population and area (km²) — denominators for per-capita / density figures.

vocab:groundPvPotentialCapacityMWp / vocab:groundPvPotentialYieldMWh / vocab:groundPvInstalledCapacityMWp

Ground-mounted (Freiflächen) PV: available potential (MWp / MWh) and installed (MWp) — Freiflächen-PV-Potenzial.

vocab:groundPvPotential200mStripMWp / vocab:groundPvPotential500mStripMWp / vocab:groundPvPotentialDisadvantagedAreasMWp / vocab:groundPvPotentialOtherAreasMWp

The Freiflächen potential split by eligible zone — 200 m BauGB strip, 500 m EEG strip, benachteiligte Gebiete, sonstige Flächen.

vocab:eeSharePvPct / vocab:eeShareWindPct / vocab:eeShareHydroPct / vocab:eeShareBiomassPct / vocab:eeShareGeothermalPct

Renewable generation mix — share of EE electricity by carrier (%) — EE-Strom nach Energieträger.

vocab:eeProductionPvMWh / …WindMWh / …HydroMWh / …BiomassMWh / …GeothermalMWh / vocab:eeProductionTotalMWh

Renewable electricity produced by carrier and in total (MWh/a, 2024).

skos:notation

The AGS, as a join-able literal — match it to linked-mastr / linked-lau on the same key.

geo:hasGeometry / geo:asWKT

Representative point of the Gemeinde (WGS84).
