Mår at a Glance
Mår is a [Kraftverk][1] (hydropower plant) located in Tinn municipality, Telemark county, Norway. Registered with the Norwegian Water Resources and Energy Directorate (NVE) under ID 288, this facility has been operational since 1948 and remains an active asset within Norway's hydropower infrastructure [2][3].
The plant operates within the Skiensvassdraget water system [4], one of Norway's significant hydrological basins. Its strategic position in the NO2 electricity price zone [5] places it within a region of established industrial and energy activity.
Ownership & Operator
Mår is operated by [STATKRAFT ENERGI AS][6], the primary concessionaire holding rights to the facility [7]. Statkraft Energi AS is a major actor in Norway's hydropower sector, managing a diversified portfolio of generation assets across multiple regions and water systems.

Hydrological Context
The plant draws water from the [Skiensvassdraget][8] catchment area [9], a water system that spans multiple municipalities and represents a critical resource for hydropower generation in the region. Understanding the hydrological characteristics of this basin—including seasonal precipitation patterns, runoff variability, and storage capacity—is essential for assessing long-term generation potential.
Detailed hydrological data, including catchment area size, mean annual inflow, and seasonal distribution, is available through the [Skiensvassdraget profile][8] and the NVE's public hydropower database.
Regional Location & Infrastructure
County (Fylke): Telemark [10] Municipality (Kommune): Tinn [11] Electricity Price Zone: NO2 [12]
Mår's location in Telemark places it within a region with established hydropower infrastructure and industrial heritage. The facility's proximity to the nearest Statnett transformer station (Mår, approximately 0.26 km away) [13] indicates efficient grid connection. The nearest major industrial zone, Herøya in Porsgrunn, is approximately 102 km away [14], reflecting the plant's position in a rural hydropower-focused area rather than an industrial cluster.
Data Centre Suitability Assessment
HydroSec's data centre suitability rating for Mår is Grade A [15], indicating strong potential for colocation infrastructure. This assessment is based on qualitative factors including grid stability, proximity to transmission infrastructure, and regional cooling conditions. The Grade A designation suggests the site could theoretically support data centre capacity in the range of approximately 36 MW [16], though this figure is indicative and subject to detailed site engineering.

Operational Status & Regulatory Framework
Mår holds an active concession from the NVE [17], confirming its legal right to operate and generate electricity. The facility's continuous operation since 1948 [18] demonstrates long-term viability and regulatory compliance within Norway's hydropower licensing regime.
All hydropower plants in Norway operate under concessions granted by the NVE, which set conditions for water use, environmental protection, and grid connection. These concessions are subject to periodic review and may include requirements for modernisation, environmental measures, or capacity adjustments.

Risks and Limitations
Hydrological Variability: Hydropower generation is inherently dependent on precipitation and runoff patterns, which vary seasonally and year-to-year. Historical production data does not guarantee future output.
Regulatory Risk: Concessions may be modified, suspended, or revoked by the NVE in response to environmental concerns, grid requirements, or changes in energy policy. Investors should monitor regulatory developments affecting hydropower in Norway.
Market Risk: Electricity prices in the NO2 zone fluctuate based on supply, demand, and interconnection with other European markets. Revenue projections should account for price volatility.
Infrastructure Risk: Grid congestion, transformer limitations, or maintenance requirements at Statnett facilities could affect generation or revenue.
Data Limitations: This profile is based on publicly available NVE data and HydroSec's proprietary assessment framework. Specific operational metrics, financial performance, and detailed site conditions require direct engagement with the operator or registered access to HydroSec's full database.
No Guarantee of Returns: Nothing in this profile constitutes investment advice, a guarantee of returns, or a recommendation to invest. Past performance and regulatory status do not ensure future profitability. Conduct independent due diligence and consult qualified advisors before making investment decisions.
