Alterra Power has completed all road construction, turbine foundations and collector lines for the 204MW Shannon wind farm in Texas.
The company said most of the 119 turbines have been fully erected.
Commissioning is underway to allow connection to the grid, and the project is now delivering limited test power.
Alterra expects commercial operations to commence in December 2015.
The announcement came in the company’s quarterly results for the period ending 30 September.
Consolidated EBITDA decreased by 17% to $17m and net interest EBITDA decreased by 17% to $14.8m, primarily due to the Canadian dollar weakening 19% versus the comparative quarter.
Consolidated revenue decreased by 25% to $12.2m and net interest revenue decreased by 22% to $22.3m primarily due to currency fluctuations, lower aluminum prices and reduced quarterly generation.
Work at the company’s 62MW Jimmie Creek hydro plant is progressing. Intake and tailrace construction is nearly complete, penstock installation is 95% complete, and the rubber dam has been fully commissioned.
Removal of the lower diversion is complete, and the facility is expected to commence generation in the summer of 2016.
Alterra chief executive officer John Carson said: “We’re excited to be in the home stretch of construction for the Shannon and Jimmie Creek hydro projects, with both projects poised to be delivered on-time and on-budget.
“Separately, our teams are working toward our next growth phase, with new project development and acquisition efforts across all clean power technologies.”
