Usta Hydroelectric Power Plant – Protective Coating Technology for Power Infrastructure
Project Overview
The Usta Hydroelectric Power Plant in Norway forms part of Jotun's portfolio of protective coating reference projects.
Hydroelectric facilities present demanding coating environments, combining steel infrastructure with continuous exposure to water, moisture and variable operating conditions.
Coating Requirements
Protective coatings within hydroelectric facilities must be considered around the specific exposure experienced by individual components.
Depending on location, steelwork may encounter atmospheric moisture, direct water exposure, condensation, abrasion and mechanical wear.
The coating system therefore needs to provide an appropriate combination of adhesion, corrosion protection, durability and resistance to the relevant service environment.
Jotun Solution
Jotun's protective coating technology was utilised at the Usta facility as part of the strategy for protecting the plant's infrastructure.
The project demonstrates Jotun's established experience in applying protective coating technology to major energy and infrastructure assets.
Asset Protection & Lifecycle Maintenance
For power-generation infrastructure, coating performance needs to be considered over the lifecycle of the asset.
Unplanned deterioration can result in additional inspection, preparation and maintenance requirements, particularly where access to equipment or structural components is difficult.
A correctly specified protective coating system can therefore contribute to the wider asset-management strategy by helping control corrosion and maintain the condition of exposed steelwork.
Why Specification Matters
There is no universal coating system suitable for every area of a hydroelectric facility.
The correct approach depends on factors including:
Substrate condition
Exposure environment
Water contact
Mechanical exposure
Required service life
Application conditions
The Usta project is a useful reminder that protective coating selection should form part of the engineering and maintenance strategy rather than being treated as a purely decorative requirement.
New Guard Coatings supplies Jotun protective coating systems for demanding industrial, infrastructure and energy applications, with technical support available to help identify appropriate coating solutions.
