Wind Park Hollern II

Wind power plant in Lower Austria, Austria. Approximate location 48.09, 16.844.

WindLower AustriaAustriaOnshore

Wind Park Hollern II is a 37 MW wind power plant in Lower Austria, Austria. It is operated by Verbund. Based on its capacity (estimated), it can supply roughly 31k homes (estimated). It ranks #72 of 131 Austria power plants by installed capacity. Commissioned in 2014, it is around 12 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 11.3% of Austria's electricity; the national grid averages 117 gCO₂/kWh (83.6% low-carbon) (2025).

Capacity provenance

The public capacity above is the current source-record value. A 2026 tracker candidate lists 33 MW for Hollern Wind Park, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

Capacity claim grade: C_REVIEW_MANUAL - recommended action: manual_review_only - confidence: unknown. This follows a claim-based data model: value + scope + source + confidence, rather than silently overwriting records.

Data provenance

The capacity and/or fuel fields on this page include a source-backed provenance label from GEM, an official registry, Wikidata, OSM, or a cross-source match.

In context: how this plant compares

Technically it is described as Onshore. Wind turbines convert moving air into electricity; output is variable and site-dependent, and modern turbines deliver some of the lowest-cost new generation on many grids.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 48.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 24% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 64/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.

Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.

Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
