Suncor Energy Products Inc. and Acciona Energia developed a 76-MW wind power generation facility in Ripley, Ontario, Canada. The project employs 38 x 2-MW Enercon E-82 wind turbines and includes two power substations.

Generated power is transmitted from the wind farm collector system to the grid through a double circuit 27-km, 69-kV transmission line.

Assessment criteria for the grid studies included:

• Contingency-based assessment, bulk power system contingencies and NPCC regional criteria
• Stability limits under increase of most critical parameter (10%)
• Pre-contingency voltage limits
• Voltage change limits
• Steady-state voltage stability

Scope of Services
Suncor and Acciona retained Hatch to manage the project and oversee implementation. The scope of work included design, procurement and specialized wind farm engineering, including modeling of the WTG in the IESO power system and specialized foundation engineering.

Hatch also provided project management and system interconnection services to the generating facility
Site safety, construction management, and engineering were handled through an integrated team approach.

Project Highlights

• The wind farm generates enough zero-emission electricity to power 24,000 homes, while offsetting 66,000 tonnes of carbon dioxide production per annum
• Fast-track implementation of innovative wind farm solutions to generate 76 MW of economical, reliable, clean power in an integrated team with Owners, suppliers and contractors. The project required just 24 months to design, construct and commission
