Sjona at a Glance
Sjona (NVE ID 367) is a hydropower plant located in Rana municipality, Nordland county, in northern Norway. Operated under active concession by HELGELAND KRAFT VANNKRAFT AS, the facility has been in operation since December 1973 and remains a key asset in the regional power generation portfolio [1][2][3].
The plant draws water from the Holmelva watershed, a hydrological system that supplies consistent seasonal flow patterns typical of Nordland's climate and topography [4]. As a Kraftverk-type installation, Sjona represents the conventional run-of-river or reservoir-based generation model that characterizes Norwegian hydropower infrastructure [2].
Ownership & Concession Status
Sjona operates under the primary concession held by HELGELAND KRAFT VANNKRAFT AS (org. no. 917424896). This entity holds the legal right to generate and dispatch power from the facility under Norwegian water law and NVE (Norges Vassdragsog Energidirektorat) oversight [3].
The plant's concession status is active as registered with NVE, meaning it remains in full operational compliance and is authorized to generate and sell electricity into the Norwegian grid [3].

Hydrological Context
Sjona draws its water supply from the Holmelva watershed system [4]. This catchment area is characterized by typical Nordland precipitation patterns, with seasonal variations that influence annual energy production cycles. Understanding the hydrological regime is essential for long-term asset valuation and grid stability planning.

Regional & Grid Integration
County (Fylke): Nordland Municipality (Kommune): Rana Electricity Price Zone: NO4 [5]
Sjona operates within the NO4 price zone, which covers northern Norway and is integrated into the Nordic power exchange (Nord Pool) and the broader European grid. This zoning determines the plant's market exposure and revenue dynamics.
Grid Connection: The nearest Statnett transformer station is approximately 17.09 km away, operating at 132 kV [6]. This distance and voltage class define the plant's transmission costs and grid stability contribution.
Industrial Proximity: The Mo i Rana Industrial Park is located approximately 27 km from the facility, representing a potential anchor load for power offtake agreements and industrial partnerships [7].
Data Center Suitability Assessment
HydroSec rates Sjona with an A-grade data center suitability score, indicating strong potential for colocation and high-performance computing applications [8].
This rating reflects:
- Reliable power supply: Active concession, stable operational history since 1973
- Proximity to grid infrastructure: 17 km to 132 kV transformer station
- Regional industrial ecosystem: Proximity to Mo i Rana industrial zone supports demand aggregation
- Capacity profile: Suitable for facilities requiring up to ~10 MW of dedicated power [8]
Important: The A-grade assessment is qualitative. Precise megawatt capacity, historical production data, and detailed technical specifications are available only to registered users after login.

Risks and Limitations
Data Availability: This public summary contains verified facts from NVE and HydroSec databases. Detailed technical and financial data require authentication and are subject to Norwegian data protection and energy sector regulations.
Hydrological Variability: Hydropower output is inherently dependent on precipitation and runoff, which vary seasonally and annually. Historical production does not guarantee future performance. Climate change may alter long-term hydrological patterns.
Regulatory Risk: Concessions are subject to Norwegian water law, environmental regulations, and periodic review by NVE. Changes in concession terms, environmental mandates, or grid policy may affect operational parameters and revenue.
Grid & Market Risk: Power prices in the NO4 zone are determined by Nord Pool and European market dynamics. Transmission constraints, grid congestion, or changes in renewable energy policy may affect dispatch and pricing.
Infrastructure Risk: The plant's age (commissioned 1973) means ongoing maintenance and potential capital expenditure for equipment renewal. Transformer station distance (17 km) may create transmission losses and grid stability considerations.
No Guarantee of Returns: This document provides factual asset information only. It does not constitute investment advice, tax guidance, or a guarantee of financial returns. Investors must conduct independent due diligence and consult qualified advisors before making investment decisions.
