Leiråa at a Glance
Leiråa is a Kraftverk (run-of-river or storage hydropower facility) located in Brønnøy, Nordland, Norway. The plant has been in operation since 28 February 2017 and is registered with the Norwegian Water Resources and Energy Directorate (NVE) under ID 1853. It operates within the NO4 electricity price zone, which covers the northern regions of mainland Norway and is part of the broader Nordic electricity market.
Operator & Ownership
The facility is operated by HELGELAND KRAFT VANNKRAFT AS, the primary concessionaire responsible for the plant's management and compliance with Norwegian hydropower regulations. Helgeland Kraft holds the operational concession from the NVE, which remains active and in good standing.
Hydrological Context
Leiråa draws water from the Leiråa catchment area, a watershed system in Nordland that feeds the plant's generation capacity. Understanding the hydrology of this river system is critical for assessing seasonal production patterns and long-term water availability—factors that directly influence investment returns and operational reliability.
Regional Location & Infrastructure
Fylke (County): Nordland Kommune (Municipality): Brønnøy Electricity Price Zone: NO4
The plant benefits from proximity to established grid infrastructure. The nearest Statnett transformer station (132 kV) is approximately 2.77 km away, ensuring reliable power evacuation to the national transmission network. The nearest major industrial hub is Mosjøen (Alcoa facility), roughly 58 km to the south, which represents potential demand centers for flexible power supply.
Data Center Suitability Assessment
Leiråa receives a Grade A rating for data center hosting potential according to HydroSec's proprietary assessment framework. This grade reflects the plant's technical characteristics, grid connectivity, and operational stability. The facility is suitable for low-power data center applications (maximum capacity approximately 1 MW), making it attractive for edge computing, blockchain validation, or other energy-intensive digital infrastructure.
Grade A indicates:
- Reliable power supply with minimal curtailment risk
- Strong grid connection to Statnett backbone
- Stable operational history since 2017
- Suitable for Tier 0 / edge-tier data center deployment
Regulatory Status & Concession
The plant operates under an active NVE concession, meaning it has met all regulatory requirements for continued operation. The concession status is verified against the official NVE register of hydropower plants in operation.
What Becomes Available After Registration
HydroSec members gain access to detailed technical specifications and financial analysis, including:
- Installed Capacity (MW) – Maximum power output
- Average Annual Production (GWh) – Historical and projected generation
- Gross Head (m) – Vertical drop utilized by the facility
- Hydrological Data – Inflow patterns, seasonal variation, drought risk
- Infrastructure Details – Penstock specifications, turbine type, efficiency metrics
- Financial Modeling – Production forecasts, revenue scenarios, and comparative benchmarking
- Sub-Scores for Data Center Suitability – Detailed assessment across power stability, cooling, latency, and grid redundancy
Risks and Limitations
Hydrological Risk: Hydropower output depends on precipitation and snowmelt patterns. Drought periods or unusually low water years can reduce generation and revenue. Long-term climate trends may alter historical hydrology patterns.
Regulatory Risk: The NVE concession is subject to periodic review and potential modification. Changes to environmental regulations, water discharge requirements, or grid connection standards could affect operations or profitability.
Market Risk: Electricity prices in NO4 fluctuate based on Nordic supply-demand dynamics, interconnection flows, and seasonal factors. Revenue from power sales is not guaranteed and depends on market conditions.
Grid Risk: Transmission constraints, maintenance outages at nearby Statnett infrastructure, or grid stability events could temporarily reduce power evacuation capacity.
Data Center Risk: Suitability assessments are based on current technical specifications. Actual data center deployment depends on commercial negotiations, cooling infrastructure development, and customer requirements not covered in this analysis.
Information Limitations: This profile is based on publicly available NVE registry data and HydroSec's proprietary assessment. Detailed financial, operational, and hydrological data require registration and are subject to data-sharing agreements with the operator.
No Guarantee of Returns: This analysis is for informational purposes only and does not constitute investment advice, a guarantee of returns, or a recommendation to invest. Past operational performance does not guarantee future results. Investors should conduct independent due diligence and consult with legal and financial advisors before making investment decisions.
