Øvre Leirfoss – Plant Overview
Øvre Leirfoss is a Kraftverk-class hydropower plant located in Trondheim, Trøndelag, Norway. Operated as part of the Nidelvvassdraget watershed system, this facility represents a key component of regional hydroelectric infrastructure in the Trøndelag region.
The plant commenced operations on 31 December 2013 and holds an active concession status with Norway's energy regulator (NVE). It is classified under NVE plant ID 516 and operates within the NO3 electricity price zone, which covers Trøndelag and parts of central Norway.
Ownership & Operator Context
Øvre Leirfoss is owned and operated by **STATKRAFT ENERGI AS**, Norway's largest energy company and a leading hydropower developer. Statkraft holds the primary concession for this facility and manages its day-to-day operations and maintenance.
As the main concessionaire, Statkraft Energi AS is responsible for ensuring compliance with Norwegian energy regulations, environmental standards, and grid connection requirements set by Statnett (the national transmission system operator).
Hydrological Context
This plant draws water from the Nidelvvassdraget watershed, one of Trøndelag's significant river systems. The Nidelvvassdraget system encompasses multiple tributaries and catchment areas that feed hydropower generation across the region. Understanding the hydrological characteristics of this watershed is essential for assessing seasonal production patterns and long-term water availability.

Regional Location & Grid Integration
Fylke (County): Trøndelag Kommune (Municipality): Trondheim Electricity Price Zone: NO3
Øvre Leirfoss operates within the NO3 price zone, which reflects regional electricity market conditions and grid constraints in central Norway. The plant is connected to the national transmission network via a nearby Statnett transformer station (66 kV), located approximately 0.06 km from the facility, ensuring efficient power evacuation to the broader grid.
The nearest significant industrial area is Verdal Industripark, approximately 70 km away, which provides context for regional industrial energy demand and potential offtake opportunities.
Data Center Suitability Assessment
Øvre Leirfoss receives a Grade A rating for data center hosting suitability within HydroSec's assessment framework. This classification reflects favorable characteristics for small-scale, mission-critical infrastructure applications.
Grade A indicates suitability for facilities with maximum power requirements of approximately 1 MW. This rating is based on:
- Grid proximity: Direct connection to 66 kV transmission infrastructure
- Operational stability: Active concession status and established operational track record since 2013
- Watershed reliability: Integration within the Nidelvvassdraget system
Data center operators and infrastructure investors should note that this suitability grade applies to Tier 0 assessments (public data). More detailed sub-scores, including power quality metrics, redundancy options, and site-specific infrastructure constraints, are available upon registration.
What You'll Access After Registration
HydroSec's registered users gain access to detailed operational and financial data currently restricted from public view:
- Installed capacity (MaksYtelse) – Maximum power output in MW
- Average annual production (MidProd) – Historical generation figures in GWh
- Gross head (BruttoFallhoyde) – Vertical drop in meters, essential for efficiency modeling
- Detailed hydrological profiles – Seasonal flow patterns and water availability forecasts
- Site infrastructure mapping – Precise coordinates, access routes, and grid connection specifications
- Sub-scores for data center suitability – Tier 1 and Tier 2 assessments with power quality, cooling, and redundancy analysis
These data points are essential for institutional investors, asset managers, and infrastructure developers conducting due diligence on hydropower-backed infrastructure projects.
Regulatory & Operational Status
- NVE Concession Status: Active
- Concessionaire: Statkraft Energi AS
- Commissioning Date: 31 December 2013
- Plant Classification: Kraftverk (hydropower plant)
- System Integration: Nidelvvassdraget watershed
The plant operates under Norwegian energy law and is subject to ongoing regulatory oversight by the Norwegian Water Resources and Energy Directorate (NVE). Concession holders are required to maintain operational standards, environmental compliance, and grid reliability obligations.
Risks and Limitations
Hydrological Risk: Hydropower generation is inherently dependent on precipitation and water inflow patterns. Drought periods or climate-driven changes in watershed hydrology can affect annual production volumes. The Nidelvvassdraget system's water availability is subject to seasonal and multi-year variability.
Regulatory Risk: Changes to Norwegian energy policy, grid connection requirements, or environmental regulations could affect operational parameters or concession terms. The NVE retains authority to modify or revoke concessions under specified circumstances.
Market Risk: Electricity prices in the NO3 zone fluctuate based on regional supply-demand dynamics, interconnection flows, and broader European energy markets. Revenue from hydropower generation is not guaranteed and depends on market conditions at the time of production.
Infrastructure Risk: Grid connection reliability depends on Statnett's transmission infrastructure. Outages or maintenance on the 66 kV connection could temporarily interrupt power evacuation.
Data Limitations: This public profile contains summary information only. Detailed operational metrics, financial performance, and site-specific infrastructure data are restricted to registered users. Investment decisions should not be based solely on public-tier information.
