Nedrefoss at a Glance
Nedrefoss is a hydropower plant located in [Harstad, Troms][1], a municipality in northern Norway. The facility has been operational since September 2004 and is classified as a Kraftverk (conventional hydropower station)[2]. It operates within the NO4 price zone of the Nordic electricity market[3], serving as part of Norway's distributed renewable energy infrastructure.
The plant is situated within the Dalelva watershed system[4], which defines its hydrological context and water supply characteristics. This integration into a larger river basin is essential for understanding seasonal production patterns and long-term yield potential.
Ownership & Operator
Nedrefoss is held under concession by **NORDKRAFT MAGASIN AS**[5], the principal rights holder responsible for operation and maintenance. Understanding the operator's track record, technical capabilities, and strategic focus is crucial for asset managers evaluating the facility's reliability and future performance.
For detailed information about the operator's portfolio, financial standing, and other concessions, visit the NORDKRAFT MAGASIN AS owner profile.
Hydrological Context
The plant draws water from the **Dalelva watershed**[6], which supplies the facility with seasonal runoff and precipitation-driven flows. The Dalelva system is a key hydrological unit in the region, and its characteristics—including average annual precipitation, snowmelt patterns, and catchment area—directly influence Nedrefoss's production profile.
Investors should review the Dalelva river profile to understand:
- Long-term hydrological trends
- Seasonal flow variability
- Competing water rights and environmental constraints
- Historical production data for comparable periods
Regional & Grid Integration
Location: Harstad, Troms[7] Price Zone: NO4[8] Nearest Statnett Transformer Station: KVITNES (~4.8 km)[9] Nearest Industrial Area: Finnfjord (Skaland) (~94 km)[10]
The NO4 price zone covers much of northern Norway and reflects regional supply-demand dynamics. Proximity to KVITNES transformer station indicates grid integration infrastructure; however, detailed voltage specifications and transmission constraints are available upon registration.
The distance to the nearest significant industrial cluster (Finnfjord) suggests limited immediate opportunities for direct power purchase agreements with large industrial consumers, though regional and national grid sales remain the primary revenue channel.
Data Centre Suitability Assessment
HydroSec Suitability Score: A (Tier 0 – Maximum Data Centre Capacity ~1 MW)[11]
This rating reflects the facility's technical and locational fit for powering small-scale, high-efficiency data centre operations. A score of A indicates:
- Reliable power supply: Operational since 2004 with active concession status[12]
- Grid connectivity: Direct access to Statnett infrastructure via KVITNES station
- Modest capacity envelope: Suitable for Tier 0 data centre deployments (up to ~1 MW)
- Northern location: Advantageous for cooling-intensive computing workloads
The assessment is qualitative and based on infrastructure proximity, operational history, and regional grid characteristics. Precise capacity figures, sub-scores for cooling, latency, and redundancy, and detailed site surveys are available to registered users.
What's Locked Until Registration
HydroSec provides tiered access to plant data. The following details are restricted to registered users:
- Installed capacity (MaksYtelse) and historical production figures
- Gross head (BruttoFallhoyde) and turbine specifications
- Average annual production (MidProd) and seasonal variability
- Detailed hydrological data for the Dalelva system
- Site infrastructure maps and transmission line routing
- Sub-scores for data centre suitability (cooling, latency, redundancy)
- Financial and tax scenario modeling
Registration unlocks these details and enables comparative analysis across Norway's hydropower portfolio.

Risks and Limitations
Regulatory & Concession Risk: Nedrefoss operates under an active NVE concession[13]. Changes to Norwegian energy policy, water rights legislation, or environmental mandates could affect operational terms or profitability.
Hydrological Variability: Production is dependent on Dalelva watershed precipitation and runoff. Drought periods, climate shifts, or upstream water diversions may reduce output below historical averages.
Grid & Market Risk: Electricity prices in the NO4 zone are subject to Nordic market dynamics, currency fluctuations (NOK/EUR), and transmission congestion. No guaranteed returns or floor prices are offered.
Data Limitations: This overview is based on publicly available NVE records and HydroSec's Tier 0 assessment. Precise capacity, production, and financial metrics require registration and are subject to operator disclosure policies.
