Driva — Geographical and Hydrological Context
The Driva river basin is a significant hydrological catchment in Norway, serving as a critical water resource for hydroelectric generation. As a defined precipitation field (nedbørsfelt), the Driva drainage area encompasses multiple municipalities and counties, making it an important focus for energy infrastructure analysis and water resource management.
The basin's hydrology and geography create the foundation for a structured hydropower portfolio. Understanding the Driva catchment requires examining both its natural characteristics and the industrial infrastructure that has been developed to harness its water resources.
Hydropower Utilization in the Driva Basin
The Driva catchment area currently hosts 5 hydroelectric power plants [0], distributed across 2 counties (fylker) [1]. This geographic spread reflects the dispersed nature of water resources and the historical development of hydropower infrastructure across the region.
The five facilities within the Driva basin represent a mix of operational scales and technologies. Each plant is independently licensed and operated, contributing to the overall energy generation capacity of the region. The plants include Vassli, Grøa, Driva, Småvoll, and Somrungen.
This portfolio demonstrates the importance of the Driva catchment to Norway's distributed hydropower network. The presence of multiple facilities within a single basin allows for integrated water management and coordinated operational strategies, though each plant operates under its own concession framework.
Ownership and Operator Constellation
The five hydroelectric plants in the Driva basin are managed by 4 different principal concessionaires [2]. This ownership structure reflects the typical Norwegian hydropower model, where water resources are allocated to multiple operators through individual concessions granted by the Norwegian Water Resources and Energy Directorate (NVE).
The presence of four distinct operators within a five-plant system indicates a competitive and diversified ownership landscape. This structure can promote operational efficiency and innovation, as each operator manages its assets independently while contributing to the broader energy supply of the region.

Risks and Limitations
Data Availability: Information presented here reflects the HydroSec database as of the current update cycle. Concession status, operator details, and plant configurations may change due to regulatory decisions, asset transfers, or operational modifications. Users should verify critical information through official NVE sources for time-sensitive decisions.
Hydrological Variability: Hydropower generation in the Driva basin is subject to precipitation patterns, seasonal water availability, and climate variability. Historical performance does not guarantee future output levels.
Regulatory Environment: Norwegian hydropower operations are subject to evolving environmental regulations, concession renewal processes, and energy market policies. Changes to these frameworks may affect plant operations and economic returns.
Incomplete Public Data: Detailed technical specifications, current capacity utilization, and financial performance metrics require authenticated access to the HydroSec platform. This overview provides structural information only.
