The new technology of wind generators will reduce the cost of energy by 10-15%: what is its essence

The technology from the CGEN company makes it possible to divide the generator into modules, which simplifies repairs and reduces costs for maintenance.

CGEN Engineering has developed modular generator technology that its founders say can reduce the cost of energy for marine renewables by 10–15%. About this writes Renewable Energy Magazine.

CGEN's modular generator system is reportedly stackable, making it easy to transport to onshore and offshore wind, wave and tidal installations. Each module can be added, replaced or moved individually. This means that energy companies can avoid long downtimes and modernize their system without major repairs.

“If a fault occurs, it can be bypassed until the module is replaced, rather than requiring a major overhaul or replacement of a complex generator system. This minimizes downtime and increases revenue from power generation,” — explained CGEN Managing Director Joseph Burchell.

The system was invented by Professor Marcus Muller from the University of Edinburgh's School of Engineering and developed by Joseph Burchell together with mechanical engineer Mike Galbraith. The team demonstrated the technology at scales ranging from 10 kilowatts (kW) to one megawatt (MW).

By comparing the data, the developers found that their technology could increase the life of turbines by 30-40% and reduce operation and maintenance costs by 50-70%, compared to conventional wind turbines. As a result, the cost of energy received can be reduced by 10–15%.

According to Joseph Burchell, the company offers modular parts manufacturing, eliminating supply bottlenecks and offering engineering expertise to support large-scale deployment. He emphasized that the technology directly addresses critical gaps in the UK's offshore supply chain.

“By replacing parts rather than scrapping the whole block, we support the circular economy, bringing us closer to achieving UK net zero,” &mdash ; noted the head of CGEN.

To develop and test its technologies, the company collaborates with various companies, including a startup from the University of Edinburgh, Mocean Energy, which uses CGEN technology in its BlueX wave energy converter.
