Summary

Norway requires licences for hydropower and watercourse regulation projects under the Water Resources Act and/or Watercourse Regulation Act, with NVE coordinating and processing applications for power plants, dams, and major installations. Licensing involves consultation and assessment and can include strict environmental conditions. Non-compliance risks stop orders, remediation, and licence amendments or revocation. The framework is fully in force and remains a focal point for balancing renewables expansion with biodiversity and protected-watercourse concerns.

Details

Jurisdictions
  • Norway
Exemptions

This framework is legally binding.

Obligations apply to:

Developers and licensees for hydropower, dams, transfers, and major energy installations.

Authorities, notably NVE, which coordinates and processes relevant applications.

Exceptions:

Some very small installations can fall under municipal handling or different approval pathways, depending on thresholds and protected-watercourse status.

What’s Required

Hydropower and major watercourse interventions require licensing under Norway’s water and energy laws. NVE processes licence applications for power plants, dams, watercourse installations, and major power lines that require permission under the Energy Act and/or Water Course Act framework.

Key requirements include:

  • Obtain a licence for hydropower projects that meet thresholds under relevant acts (Water Resources Act and/or Watercourse Regulation Act), including associated environmental conditions.

  • Follow defined licensing procedures (consultation, assessment, and decision-making) involving NVE and, depending on project size/type, higher authorities.

  • Licences may be revised, amended, revoked, or refused in line with the legal framework and authority powers, including revision matters.

Important Deadlines

  • Project-specific: licensing timelines are governed by application completeness, EIA/consultation steps, and authority processing time.

  • Small-scale hydropower: procedural handling differs based on project category; definitions for small-scale (for example, <10 MW criteria referenced in sector descriptions) influence the process route.

Current Status

Fully in force. Hydropower licensing remains central to balancing renewables, flood and landslide protection, biodiversity, and local acceptance, with policy debates continuing around protected rivers.

Penalties for Non-Compliance

  • The primary consequence is administrative: orders to stop, rectify, or bring the project back into compliance with licence conditions, including potential licence changes or revocation in serious cases.

Examples of Known Violations

  • Typical violations include construction without a required licence, material deviation from approved designs, or non-compliance with environmental licence conditions, leading to enforcement actions and potential project suspension.
