Trollheim at a Glance
Trollheim (NVE ID 454) is a hydropower plant located in Surnadal, Møre og Romsdal county, in the Surna river system. The facility has been in operation since 1968 and remains an active asset in Norway's power generation portfolio. It operates within the NO3 electricity price zone, serving the Nordic power market.
The plant is classified as a Kraftverk (conventional hydropower station) and is operated by STATKRAFT ENERGI AS, Norway's largest energy company and primary hydropower operator. The facility's commissioning date of 26 September 1968 reflects its long operational history and proven reliability in the Norwegian hydropower sector.
Ownership and Operator Context
STATKRAFT ENERGI AS holds the primary concession for Trollheim. As Norway's leading hydropower operator, Statkraft manages a substantial portfolio of facilities across the country, with particular concentration in regions like Møre og Romsdal. The company's operational mandate includes maintenance, optimization, and compliance with Norwegian energy regulations administered by the Norwegian Water Resources and Energy Directorate (NVE).
The concession status is active, confirming that the facility operates under valid regulatory authorization and meets all current licensing requirements.
Hydrological Context
Trollheim draws water from the Surna river system, which serves as its primary hydrological input. The Surna watershed (Nedbørsfelt) provides the catchment area that sustains the plant's water supply. Understanding the hydrological characteristics of this system is essential for assessing seasonal production patterns and long-term yield stability.
Detailed hydrological data—including gross head, catchment area, and mean annual inflow—is available to registered users on the HydroSec platform. These metrics directly influence production forecasts and investment return profiles.
Regional Location and Grid Integration
County: Møre og Romsdal Municipality: Surnadal Electricity Price Zone: NO3
The plant's location in NO3 positions it within a distinct price zone that reflects regional supply-demand dynamics and transmission constraints. The nearest Statnett transformer station is Trollheim itself, located approximately 0.6 km from the facility, facilitating direct grid connection. Voltage classification for this connection is not publicly disclosed.
The nearest industrial cluster is Sunndalsøra (Hydro), approximately 44 km away, which may be relevant for understanding regional industrial energy demand and infrastructure development.
Data Centre Suitability Assessment
Trollheim receives a Grade A rating for data centre hosting potential, based on HydroSec's proprietary suitability framework. This classification indicates that the facility's characteristics—including location, grid access, and operational profile—align well with the technical and logistical requirements of hyperscale data centre deployment.
A Grade A rating suggests capacity headroom suitable for data centre loads of approximately 25 MW, though this is a qualitative estimate and subject to detailed site engineering. Actual feasibility depends on:
- Grid capacity and transmission constraints at the Trollheim substation
- Cooling infrastructure requirements and water availability
- Regulatory and planning approvals from local and national authorities
- Contractual arrangements with the current operator
Detailed technical scores, site infrastructure maps, and feasibility studies are available to registered institutional investors on the HydroSec platform.

- Financial frameworks: Lease structures, power purchase agreements, and operational cost benchmarks
- Sub-scores for data centre suitability: Cooling availability, land availability, and grid stability metrics
Risks and Limitations
Hydrological Variability: Hydropower output is inherently dependent on precipitation and runoff patterns. Drought periods, climate change, and long-term precipitation trends introduce production volatility that cannot be fully predicted.
Regulatory Risk: Norwegian energy policy, grid regulations, and environmental protections are subject to change. Concession renewals, environmental mandates, and grid connection standards may affect operational economics.
Market Risk: Electricity prices in the NO3 zone fluctuate based on Nordic supply-demand dynamics, interconnection flows, and international energy markets. Revenue exposure to spot prices introduces earnings volatility.
Operational Risk: Equipment aging, maintenance requirements, and unplanned outages can reduce availability and output. The facility's 1968 commissioning date means certain components may require modernization.
Data Limitations: This page presents information derived from NVE public registers and HydroSec's data aggregation. Specific technical and financial details require direct engagement with the operator or registered access to HydroSec's institutional platform.
