This posting is for a proposed amendment to existing Renewable Energy Approval #5460-98BPH8 held by Dufferin Wind Power Inc. for the Dufferin Wind Power Project, located in the Township of Melancthon, Town of Shelburne and Township of Amaranth, County of Dufferin.
The turbine manufacturer, General Electric (GE), has undertaken an optimization study that will increase the power generation of the facility when wind resources are available, while maintaining or lowering current noise levels at receptors. The proposed amendment for this project is to increase the overall power generation of the facility from 91.387 megawatts alternating current, but will not exceed the approved nameplate capacity of 99.1 megawatts alternating current.
This proposed change is a software upgrade to only 31 of the 49 wind turbines. The software upgrade simply implements the latest technological advancements in wind power generation for the wind turbines – similar to upgrading software on a computer. The number and location of the approved wind turbines will not change and the facility’s output will not exceed its authorized nameplate capacity.
The noise modeling for the proposed amendment has been completed as per the minstry’s stringent Noise Guidelines. The noise modelling was based on a worst-case scenario using the maximum noise profiles for each of the turbine models. Based on the results of the submitted Acoustic Assessment Report, with the software upgrade, the facility remains in compliance with the most stringent noise limit (<40 dBA) at all existing and assumed future receptors.
Dufferin Wind Power Inc. is also proposing to install a grounding cable east of T1 to approximately 200 metres west of the Mulmur Melancthon Townline. The grounding cable is necessary to facilitate the change in turbine operation and enhance the underground electrical collector system.
The ministry requested that Dufferin Wind Power Inc. hold a public meeting to consult on the proposed software change and grounding cable addition. Public meetings were held in Shelburne, Amaranth and Melancthon in October 2017.
The purpose of this notice is to allow opportunity for the public to comment on the proposed changes, Modification Document and the Consultation Addendum Report prepared in support of this amendment application. All comments received as a result of this 30 day comment period will be considered as part of the decision-making process by the ministry.
The project consists of 49 wind turbines, two meteorological towers and a 47 kilometre 230 kilovolt (kV) transmission line connecting the wind facility to the Hydro One Networks Inc. transmission system via the Orangeville transmission station.
The facility is considered to be a Class 4 facility under Ontario Regulation 359/09 (O. Reg. 359/09) Renewable Energy Approvals under Part V.0.1 of the Environmental Protection Act. Applications for Renewable Energy Approvals are required to be submitted in accordance with O. Reg. 359/09 for consideration for approval.
