ORC turbines are usually paired with 4-pole generators equipped with gearboxes for these applications. Desiring a more compact and efficient system, the OEM asked Nidec to engineer a 2-pole generator that would not require a gearbox. Nidec responded by designing a 2-pole synchronous generator to match turbine performance. The generator couples directly to the turbine to offer a more robust and efficient solution than the traditional configuration, resulting in lower life cycle costs, a smaller footprint, less maintenance and greater plant reliability.
The plant today produces 5 MWe of electricity per year with annual savings of approximately 20,000 tons of greenhouse gases. Since its completion, Nidec has partnered with the OEM to create a complete line of ORC turbine generators for plants supplied to the Turkish market.
