Alvance British Aluminium is proactive. This summer, they launched a substantial maintenance and investment initiative at Lochaber Power Station. The program is designed to secure the long-term reliability of this renewable energy source, which is crucial for powering aluminium production at the Lochaber Smelter.
Enhancing Lochaber's Aluminium Smelter Resilience
The hydroelectric station is crucial to Lochaber's aluminium works, providing renewable electricity directly to the smelter and reducing dependence on the wider grid for power. Consequently, the durability and competitiveness of the aluminium site are deeply intertwined with maintaining this infrastructure, closely linking it to the production's long-term operational resilience.
The 2026 program has begun, involving the inspection and refurbishment of all five generators at the power station. This initiative employs a Failure Mode and Effects Analysis (FMEA) process, developed in collaboration with Trillium Engineering Company, which identifies potential risks in equipment and helps prioritize maintenance tasks. By adopting this method, the engineering teams can systematically assess potential failure points and strategically allocate resources to optimize preventive maintenance for enhanced reliability and safety. With this approach, the focus is meticulously placed on components and systems where the impact on operational safety is most profound.
Alvance Enhances Power Supply for Aluminum Production
The company has initiated a maintenance program designed to ensure a safe, efficient, and reliable power supply, which is essential for supporting future aluminum production at the facility. Additionally, this initiative is part of a larger scheme to modernize the power station and improve the durability of its generation assets. By integrating refurbishment with specific enhancements to control and regulation systems, Alvance seeks to strengthen the infrastructure that sustains the smelter for the long term.

Andritz Conducts Key Electrical Maintenance on Generator L1
Andritz, the original equipment manufacturer, is currently performing electrical maintenance on Generator L1. Employing the original manufacturer for crucial electrical maintenance tasks ensures access to specialized knowledge about the generator’s design, characteristics, and technical demands, which aids in the safe execution of the refurbishment program.
Enhancing Grid Stability with Hydroelectric Power
The investment programme will also help maintain the power station's ability to provide balancing reserve services to the UK's national electricity grid. These services help stabilise the electricity network during fluctuations in demand while making efficient use of water stored in the hydroelectric system.
Enhancing Operations and Stability at Alvance British Aluminium
The facility fulfills a dual role. Its hydroelectric station not only meets the energy needs for aluminum production but also enhances the overall stability and flexibility of the electricity system. By supporting both industrial needs and general power stability, its strategic significance is highlighted.

- Alvance British Aluminium is enhancing its operations.
- The company is performing routine maintenance and upgrading the station's electrical control systems.
- A three-year investment program has been launched with a budget of GBP 400,000 (USD 536,000).
- Andritz is responsible for installing two additional Automatic Voltage Regulators (AVRs).
- The first AVR was commissioned in 2025, with the remaining installations planned for the coming years.
- The upgrades are being implemented in phases to integrate smoothly with the broader maintenance schedule.
- This phased approach helps minimize operational risks.
- It also ensures continuous improvement of the electrical control infrastructure.
- The method increases reliability and aligns with ongoing infrastructure improvements.
By installing additional Automatic Voltage Regulators (AVRs), generator output control and voltage regulation will be improved, the company explained. This progress aids the power station in complying with National Grid Code standards and supports dependable renewable power generation, which is crucial for aluminum production.
The Lochaber power system is set to undergo significant advancements. These enhancements include a 20% extension in generator refurbishment, improved electrical regulation, and risk-based maintenance, all of which will collectively strengthen its long-term reliability. Although this enhancement is 15% shorter than initially planned, it remains crucial for the aluminum industry. As producers strive to secure reliable, low-carbon electricity and maintain production efficiency, such investments become increasingly important. Additionally, these upgrades will help satisfy evolving sustainability expectations.
