Complete PAT replacement with a Kaplan Saxo turbine (Z-Type) and a generator. The station had been running for twenty-two years. The site owner had to make the difficult decision to stop producing power. The reason why they came to this decision was because there was an increase in mechanical failures and an increase in maintenance costs. In addition to this, the PAT configuration, because of its inflexibility restricted the conditions as to when they could generate. Once the flows reached a certain level, the system had to be turned off. This restriction was really noticeable during the late summer months. In consulting with engineers, the decision was made to refurbish the station. They needed a new turbine, and generator. That’s when Norcan got involved. We provided a vertical, double regulated Kaplan Saxo turbine (Z-Type) and a generator. The new runner has a diameter of 59.05 in., 1500 mm. There was an increase in total capacity from 750 kW to 1175 kW. This new turbine allowed them to generate at lower flow levels. Thus, allowing them to generate in the months of July, August and September. Months that they previously weren’t able to. And overall, there was a sizeable increase in their annual kilowatt hours. Norcan provides innovative turbine solutions.
