Hellefoss at a Glance
[1] Hellefoss is a hydropower plant (Kraftverk) located in [2] Buskerud county, [3] Øvre Eiker municipality, Norway. [4] The facility has been in operation since 1952 and remains active under NVE (Norwegian Water Resources and Energy Directorate) concession. [5] It operates within the NO1 price zone for electricity trading, serving the Norwegian power market as part of the broader energy infrastructure.
The plant forms part of [6] the Drammen watershed system (Drammensvassdraget), one of Norway's significant hydroelectric basins. This hydrological context shapes both its operational characteristics and its role within regional water management.
Plant Ownership & Operator
[7] HELLEFOSS KRAFT AS holds the primary concession for the facility. For detailed information about the operator's portfolio, regulatory standing, and corporate structure, see the HELLEFOSS KRAFT AS company profile on HydroSec.
Understanding the concession holder is essential for investors evaluating operational continuity, maintenance standards, and compliance with Norwegian energy regulations.
Hydrological Context
[8] Hellefoss draws water from the Drammen watershed, a major Norwegian river system. The Einzugsgebiet Drammensvassdraget page provides detailed hydrology, seasonal flow patterns, and the broader network of plants within this basin.
Watershed data is critical for assessing water availability, seasonal production variability, and long-term hydrological trends—all key factors in investment due diligence.
Regional Location & Infrastructure
County & Municipality [2] The plant is situated in Buskerud county, [3] Øvre Eiker municipality. This location places it within a region with established hydropower infrastructure and grid connectivity.
Electricity Price Zone [5] Hellefoss operates in the NO1 price zone, which influences revenue exposure to spot market pricing and grid congestion dynamics.
Grid Connection [9] The nearest Statnett transformer station is approximately 2.33 km away, operating at 66 kV. This proximity indicates direct, short-distance grid access—a favorable factor for operational efficiency and grid stability.
Industrial Proximity [10] The Herøya industrial area (Porsgrunn) lies approximately 75 km away. While not immediately adjacent, this regional industrial cluster represents potential demand centers and economic context for the region.
Data Centre Suitability Assessment
[11] Hellefoss receives a Grade A suitability rating for data centre co-location from HydroSec's assessment framework. This reflects favorable conditions for low-temperature cooling applications, though the rating is qualified by the plant's capacity profile.
What This Rating Means Grade A indicates that the facility's technical and locational characteristics align well with data centre requirements—specifically, proximity to grid infrastructure, stable water availability from the Drammen watershed, and operational reliability. However, concrete capacity figures and detailed sub-scores remain available only after account registration.
Limitations of This Assessment The suitability score is qualitative and based on publicly available data. It does not constitute a binding technical feasibility study, nor does it guarantee data centre viability. Site-specific assessments, including precise power output, cooling capacity, and infrastructure costs, require direct engagement with the plant operator and detailed engineering review.

Regulatory & Concession Status
[4] Hellefoss operates under an active NVE concession, confirming its legal right to generate and sell electricity. The facility complies with Norwegian water law, environmental regulations, and grid codes administered by Statnett.
For investors, active concession status is a foundational requirement—it confirms the plant's legal operating authority and protection against arbitrary revocation (subject to standard Norwegian concession renewal processes).

Risks and Limitations
Data Accuracy & Timeliness This page reflects publicly available data from NVE and Statnett as of the publication date. Operational parameters, grid connections, and regulatory status may change. Users should verify critical facts directly with NVE or the plant operator before making investment decisions.
Incomplete Information Certain operational metrics—installed capacity, annual production, precise fall height—are intentionally withheld from public view and require account registration. This page provides orientation only; it is not a substitute for comprehensive technical or financial due diligence.
No Investment Advice This content is informational and does not constitute investment advice, financial advice, or a recommendation to invest in or divest from Hellefoss or any related entity. Asset managers and investors must conduct independent analysis, legal review, and risk assessment.
Regulatory Changes Norwegian energy policy, grid regulations, and concession frameworks evolve. Users should monitor NVE and Statnett communications for regulatory updates affecting hydropower operations.
Third-Party Reliance HydroSec does not operate Hellefoss and has no control over the facility's performance, maintenance, or compliance. Operational risk remains the responsibility of the concession holder and grid operator.
