The thermal power plant generator turbine uses Diesel and Ethanol, the switch between these two fuels is quite complex and the process must be followed carefully. The challenge was to use pipes that have low head losses and are compatible with both fuels. Due to Ethanol’s potential to generate charge, it requires the highest possible level of safety.
The site is quite narrow (narrow plot stretching lengthwise) and the different contractors: civil construction, piping, turbine installers, and similar needed to work as quickly as possible to avoid blocking the site and slowing the build schedule. Réunion Island is also prone to hurricane and tropical heavy rains, meaning the sumps needed to be completely liquid tight.
