Øyreselva — Geographical and Hydrological Context
The Øyreselva river basin represents a defined hydrological catchment area in Norway with significant hydropower infrastructure. As a key water resource, the Øyreselva drainage basin supports multiple power generation facilities that contribute to Norway's renewable energy portfolio [1].
The basin's hydrological characteristics and geographic positioning make it an important area for understanding regional water resource management and energy production. The catchment area encompasses specific geographical boundaries that define water flow patterns and hydropower potential within the region [1].
Hydropower Utilization in the Øyreselva Basin
The Øyreselva catchment currently hosts 2 hydropower plants [2] that operate within this defined drainage area. These facilities represent the active hydropower infrastructure managed across the basin's hydrological system.
The plants operating in this region are:
- **Jukla** — a key facility within the basin
- **Markjelkevatn** — another significant installation
These installations collectively form the hydropower generation capacity of the Øyreselva basin. Each facility operates under specific concession frameworks established by Norwegian energy authorities.
Regional Distribution and Administrative Context
The Øyreselva hydropower infrastructure is concentrated within 1 county (fylke) [3], reflecting the basin's geographic scope and administrative organization within Norway's regional structure.
This regional concentration simplifies operational oversight and regulatory compliance, as all facilities fall under a single county jurisdiction. This administrative alignment is typical for well-defined river basins where hydropower development has followed natural hydrological boundaries.
Ownership and Operator Structure
The hydropower assets in the Øyreselva basin are operated by 1 primary concession holder [4]. This unified operator structure means that all 2 plants within the catchment area are managed under a single ownership or concession framework.
A single operator managing multiple facilities within a basin can offer operational efficiencies, coordinated maintenance scheduling, and integrated water management across the hydrological system. This consolidation is common in Norwegian hydropower, where large operators manage portfolios of complementary assets.
Data Access and Further Analysis
Detailed technical specifications, production data, and financial metrics for individual plants are available to registered users on the HydroSec platform. Our database integrates real-time information from the Norwegian Water Resources and Energy Directorate (NVE) and provides institutional-grade analytics for asset managers, family offices, and institutional investors.

Risks and Limitations
Data Currency: The hydropower asset data presented reflects information current at the time of database update. Ownership structures, concession holders, and operational status may change. Users should verify critical information directly with the NVE or relevant operators for time-sensitive investment decisions.
Hydrological Variability: Hydropower production in Norwegian basins is subject to significant seasonal and annual precipitation variation. Historical production does not guarantee future output. Water availability, inflow patterns, and climate factors directly affect asset performance.
Regulatory Changes: Norwegian energy policy, grid regulations, and concession frameworks are subject to modification. Changes in environmental regulations, water management priorities, or energy market structures may impact asset valuation and operational economics.
Incomplete Information: Not all technical or financial details are publicly available. Some operational data, maintenance records, and forward-looking metrics require direct contact with operators or access to restricted databases.
No Investment Advice: This page provides factual information about hydropower infrastructure only. It does not constitute investment advice, financial recommendation, or valuation guidance. Investors must conduct independent due diligence and consult qualified advisors before making investment decisions.
