Tverrelva at a Glance
Tverrelva is a Kraftverk-class hydropower plant located in Senja municipality, Troms county, in northern Norway. [1] Registered with the Norwegian Water Resources and Energy Directorate (NVE) under plant ID 850, [2] the facility has been in continuous operation since 31 December 1984. [3] It forms part of the Rossfjordvassdraget watershed system, [4] which supplies the hydrological foundation for power generation in this region.
The plant feeds into the NO4 price zone of Norway's electricity market, [5] positioning it within the broader Statnett transmission infrastructure that connects northern Norwegian generation to the national grid.
Ownership and Operator
Tverrelva is operated by **TROMS KRAFT PRODUKSJON AS**, [6] the primary concession holder responsible for the facility's management and compliance with Norwegian energy regulations. Understanding the operator's track record, maintenance standards, and strategic direction is essential for asset managers evaluating long-term performance and investment risk.
Hydrological Context
The plant draws water from the Rossfjordvassdraget catchment area, [7] a watershed system that determines seasonal water availability, inflow patterns, and production variability. Investors should review detailed hydrological data—including long-term precipitation records, runoff statistics, and climate-adjusted projections—to model expected energy output under different scenarios. Such data becomes available upon registration on the HydroSec platform.
Regional Location and Grid Integration
Fylke (County): Troms [8] Kommune (Municipality): Senja [9] Elspot Price Zone: NO4 [10]
Tverrelva's proximity to grid infrastructure is a key operational parameter. The nearest Statnett transformer station operates at 132 kV and is located approximately 6.24 km away, [11] providing the connection point for power evacuation to the national transmission network. The Finnfjord industrial area (Skaland) lies roughly 6 km distant, [12] offering potential for future industrial offtake agreements or power-purchase partnerships.
Data Centre Suitability Assessment
HydroSec rates Tverrelva's suitability for data-centre hosting at Grade A, [13] indicating strong potential for colocation infrastructure development. This assessment reflects the plant's operational stability, grid connectivity, and thermal characteristics. However, the specific megawatt capacity and detailed sub-scores remain restricted to registered users; login to access full technical specifications.
What Becomes Available After Registration
The following detailed parameters are published exclusively to registered asset managers and institutional investors:
- Installed capacity (MaksYtelse) and historical production profiles
- Average annual production (MidProd) and seasonal variation
- Gross head (BruttoFallhoyde) and efficiency metrics
- Detailed hydrological analysis including runoff curves and drought scenarios
- Site infrastructure maps showing grid connections, access roads, and cooling-water availability
- Sub-scores for data-centre suitability across power density, cooling, and latency dimensions
Concession Status and Regulatory Framework
The plant's concession status with NVE is currently unrecorded in the public registry. [14] Investors should verify current regulatory standing and any pending license renewals or modifications directly with the Norwegian authorities or through HydroSec's registered-user portal.
Risks and Limitations
Hydrological Variability: Hydropower output depends entirely on precipitation and runoff in the Rossfjordvassdraget system. Climate change, drought cycles, and extreme weather events introduce production volatility that cannot be eliminated through operational management alone.
Grid Congestion: The 132 kV connection to Statnett may face seasonal congestion during peak generation periods, potentially limiting revenue realization or requiring curtailment.
Regulatory Risk: Norwegian energy policy, carbon pricing, and grid tariff structures are subject to change. Concession renewals and environmental compliance requirements may impose additional costs or operational constraints.
Data Limitations: This public profile presents only summary information. Critical investment decisions require access to full technical specifications, historical production data, and detailed hydrological modeling—all available to registered users only.
No Guarantee of Returns: Past operational performance does not guarantee future output or financial returns. All investment decisions should be supported by independent technical due diligence and professional financial advice.
