Kaldåga at a Glance
Kaldåga is a Kraftverk (hydropower plant) located in Vefsn municipality, Nordland county, Norway [1][2][3]. The facility has been in continuous operation since November 1958 [4], making it a mature asset within the Norwegian hydropower infrastructure. It is registered with the Norwegian Water Resources and Energy Directorate (NVE) under ID 195 [1].
The plant operates within the Drevja watershed system, a key hydrological unit in the region [5]. Its electricity output is dispatched to the NO4 price zone, which covers parts of Nordland and reflects regional market dynamics [6].
Ownership & Operator Context
Kaldåga is owned and operated by **HELGELAND KRAFT VANNKRAFT AS**, the primary concession holder [7]. This entity holds the legal right to generate and distribute power from the facility under Norwegian hydropower concession law. Understanding the operator's portfolio and track record is essential for investors evaluating asset stability and operational competence.

Hydrological & Geographic Context
Kaldåga draws water from the Drevja catchment area, a significant watershed in Nordland [5]. The plant's position within this hydrological system determines its water availability, seasonal flow patterns, and long-term production potential. Investors should review detailed hydrological data—including precipitation patterns, runoff characteristics, and historical inflow variability—to assess production stability.
The facility is situated in Vefsn municipality within Nordland county [2][3], a region with substantial hydropower infrastructure and industrial demand. The nearest major industrial cluster is Mosjøen (approximately 25 km away), home to significant aluminium smelting operations [8], which influences local electricity demand and pricing dynamics.
Grid Connection & Infrastructure
Kaldåga connects to the transmission network via an unnamed Statnett transformer station approximately 0.1 km away, operating at 66 kV [9]. This proximity to grid infrastructure ensures reliable evacuation of generated power. The short distance to the connection point minimizes transmission losses and operational complexity.
The plant's strategic location relative to industrial demand centers and grid infrastructure supports consistent market access for its output.
Data Center Suitability Assessment
Kaldåga receives a HydroSec Data Center Suitability Grade: A [10], indicating strong potential for supporting data center operations. This grade reflects the facility's capacity profile (estimated maximum output approximately 3 MW) [10], operational reliability, and grid connectivity.
A Grade A rating suggests the plant could reliably support mission-critical computing infrastructure requiring stable, renewable power. However, detailed technical specifications—including precise capacity, minimum guaranteed output, and seasonal variability—are available only to registered users on the HydroSec platform.
Regulatory Status & Concession
Kaldåga holds an active concession status with the NVE [11], confirming its legal right to operate and generate hydropower. The facility operates under Norwegian hydropower regulations, which govern environmental compliance, water management, and grid integration requirements.
Investors should verify current concession terms, renewal dates, and any environmental or operational conditions that may affect long-term viability.
What Becomes Available After Registration
The HydroSec platform provides additional proprietary data and analysis for registered users:
- Precise installed capacity and maximum output (MW)
- Historical and projected annual production (MWh)
- Gross head and hydrological characteristics
- Detailed location mapping and infrastructure proximity analysis
- Sub-scores for data center suitability (power stability, cooling water availability, grid redundancy)
- Comparative benchmarking against similar plants in the region
- Hydrological trend analysis and climate-adjusted production forecasts
These insights enable institutional investors and asset managers to conduct rigorous due diligence before commitment.
Risks and Limitations
Hydrological Variability: Hydropower output depends on precipitation and runoff, which fluctuate seasonally and annually. Historical production data and long-term hydrological modeling are essential to assess revenue stability.
Regulatory & Concession Risk: Changes to Norwegian hydropower regulations, environmental requirements, or concession terms could affect operational costs or revenue. Investors must review current concession documents and monitor regulatory developments.
Market Price Risk: Power prices in the NO4 zone reflect regional supply-demand dynamics and broader Nordic electricity markets. Revenue exposure to wholesale prices requires hedging strategies or long-term power purchase agreements.
Grid & Infrastructure Risk: Dependence on Statnett transmission infrastructure means that grid outages or maintenance could temporarily interrupt power evacuation, though the short distance to the connection point mitigates this risk.
Data Limitations: This public profile provides overview information only. Detailed technical, financial, and hydrological data require registration and access to the full HydroSec database. Investment decisions should not be based on this summary alone.
No Guarantee of Returns: This profile does not constitute investment advice, tax guidance, or a guarantee of financial performance. Prospective investors must conduct independent technical, legal, and financial due diligence before committing capital.
