As the local electricity distribution company, St. Thomas Energy Services has a customer base of approximately 18,000 customers.  In order to realize growth opportunities and to become more involved in the growing Renewable Energy Sector, a holding company was formed that purchased a number of private businesses that serve energy markets.

The initiative is called Partners in Power and leverages the knowledge of various companies to position themselves to assist in the construction and maintenance of renewable energy projects throughout the country.  The three companies are:

  • Tiltran – Located nearby in Tillsonburg, this company focuses on high-voltage electrical engineering, construction and maintenance of renewable energy installations.  They are currently involved in over 100 projects in Ontario, including a 10 MW wind farm in Chatham-Kent (installation and project management of the operation’s electrical collector systems), and Canada’s largest wind turbine installation at Wolfe Island.
  • Lizco Sales – Also located in Tillsonburg, this company provides power equipment, with an emphasis on transformers.  They have the largest privately-owned new transformer inventory in Canada.
  • Tal Trees Construction – Located in Belleville this organization specializes in site engineering and construction and maintenance of high voltage sub-stations, transformers and overhead lines.

The partnership focuses on three different roles in renewable energy projects:

1.  Project development and maintenance of renewable energy installations

2.  Contractor of specific elements for renewable energy projects

3.  Ownership of their own renewable energy installations

St. Thomas Energy Services is unique in Ontario as they take an active role in investment attraction and business development for the sector.  The Partners in Power partnership therefore highlights not only the benefits of working with the City-owned local distribution on new project development, but also the progressive public-private entrepreneurial nature of the community, with an obvious focus on the Renewable Energy Sector.

This group of companies is currently involved in many of the major renewable projects across the province.
