Høyanger K5A – Overview
Høyanger K5A is a hydropower plant (Kraftverk) located in Høyanger municipality, Vestland county, Norway. [1] The facility has been in operation since 29 June 1965 [2] and is managed by STATKRAFT ENERGI AS, the principal concession holder. [3] The plant operates within the NO3 electricity price zone, which covers parts of central and western Norway. [4]
This facility represents a significant component of Norway's distributed hydropower infrastructure, contributing to the country's renewable energy portfolio in the western region.
Ownership & Concession Status
STATKRAFT ENERGI AS holds the primary concession for Høyanger K5A. [3] The facility maintains an active operational status according to the Norwegian Water Resources and Energy Directorate (NVE). [5] As a Statkraft-operated asset, the plant is part of one of Norway's largest energy producers, with extensive experience in hydropower generation and grid integration.
The concession framework ensures regulatory oversight and compliance with Norwegian energy law and environmental standards.
Hydrological Context
Høyanger K5A draws water from the Øyrelva watershed, a key hydrological system in the region. [6] The plant's integration into this catchment area determines its seasonal water availability and generation profile, which are critical factors for long-term performance assessment.
Detailed hydrological data, including precipitation patterns, runoff characteristics, and historical inflow volumes, are available upon registration in the HydroSec platform.
Regional Location & Grid Connection
Municipality: Høyanger County (Fylke): Vestland Price Zone: NO3 [4]
The facility benefits from proximity to critical grid infrastructure. The nearest Statnett transformer station is located approximately 0.3 km away at 66 kV voltage level, [7] ensuring efficient power evacuation. Additionally, the Høyanger industrial zone (operated by Hydro) is located in immediate proximity, [8] reflecting the region's established industrial energy demand.
Data Center Suitability Assessment
HydroSec's technical evaluation assigns Høyanger K5A a Grade A data center suitability rating, indicating strong potential for colocation applications. [9] This assessment reflects the facility's operational stability, grid connectivity, and thermal characteristics suitable for high-performance computing infrastructure.
The maximum estimated data center capacity is approximately 19 MW, [9] though precise technical specifications and detailed site infrastructure assessments are restricted to registered users.
What You'll Access After Registration
The HydroSec platform provides comprehensive, proprietary data on Høyanger K5A available exclusively to registered members:
- Detailed capacity metrics (maximum output, average production, gross head)
- Advanced hydrological analysis (inflow forecasts, seasonal patterns, historical performance)
- Site infrastructure mapping (transformer specifications, grid connection details, cooling water availability)
- Sub-component suitability scores for data center deployment
- Comparative benchmarking against similar facilities in the Øyrelva system and Vestland region
Risks and Limitations
Data Completeness: While HydroSec aggregates official NVE registry data, certain operational details (real-time generation, maintenance schedules, future concession modifications) are not publicly available and require direct contact with the operator.
Hydrological Variability: Hydropower generation is inherently dependent on precipitation and snowmelt patterns. Historical performance does not guarantee future output. Climate variations, drought periods, and extreme weather events can materially affect generation profiles.
Regulatory Risk: Changes to Norwegian energy policy, grid tariffs, environmental regulations, or concession terms could impact operational economics. The facility operates under a concession framework subject to periodic review and modification.
Grid Constraints: While the facility has good grid connectivity, transmission congestion or grid stability requirements may occasionally limit power evacuation, affecting revenue potential.
Technology & Infrastructure: Aging infrastructure (the plant has been operational since 1965) may require capital investment for maintenance, modernization, or environmental compliance. Specific capex requirements are nicht öffentlich publiziert.
Data Center Assumptions: The Grade A suitability rating is based on technical parameters; actual deployment feasibility depends on site-specific conditions, operator agreements, and cooling infrastructure that require on-site verification.
