Kestrel Power Engineering was formed to provide utilities with access to specialized expertize in the area of generator control. With decades of experience in Ontario Hydro, formerly one of North America's largest electric utilities, we bring proven expertise and solutions to your problems. As former utility engineers and technologists we understand the difficulty of dealing with complex technical problems in Companies that are increasingly distracted by financial, political and regulatory issues. Our service offerings are designed to provide you with access to the latest technical expertise while helping you understand the impact of recent regulatory developments on your day-to-day activities.

From Our Clients:

"We would like to take this opportunity to thank you for your dedication and assistance during our annual shutdown. Your help in fast tracking this project and getting it to where it is today is greatly appreciated. The hard work and long hours put into this project are reflected in its accomplishments. Never before has this mill been able to import power from the utility in any of the scenarios tested with such little impact to the power system as a whole. Your willingness and dedication in pursuing issues outside of the contracted work is also very appreciated."

"We hope you found this project as interesting and challenging as we did, we also hope your experience at our facility was an enjoyable one. In discussions with our people who were involved in the project they found it to be a great learning opportunity and appreciated your sharing of information and knowledge. We look forward to working together again in the future if the opportunity presents itself. " …Alberta Pacific Forest Industries Inc.
