Capstone secures order for two waste-to-energy projects

Capstone Green Energy Corporation ( (Capstone) announced that IBT Connecting Energies GmbH ( has secured orders for two waste-to-energy projects in the Sardinia region of Italy. Three C65 microturbines will be deployed at two wastewater treatment facilities operated by Acciona Agua SA in Alghero and Cagliari, Italy. The microturbine systems are expected to be commissioned in December 2022.
Once commissioned, the microturbines will cleanly and effectively operate on the biogas, or “green waste”, produced on-site from municipal solid waste. In addition, the new cogeneration plants will incorporate a customized heat recovery module (HRM), advanced gas treatment, compressors, and SCADA control panels. Together, the configuration will allow plant operators to harness the waste fuel for on-site power production.
The microturbines will be utilized in a combined heat and power (CHP) application and produce electricity and hot water for the customer’s wastewater treatment facilities.
Wastewater treatment plants are excellent candidates for microturbine-based CHP. These installations can bring fast payback from utility power and natural gas savings by utilizing waste methane. In addition, excess renewable electricity could be offered for sale to the electric utility.
