In 2011, ENMAX Energy launched its Generate Choice, a program which offers Albertans home-based renewable energy choices such as solar power and wind generation (ENMAX 2011:7). Response to the program has been poor: by August 2011, only 3,100 people even expressed interest in having a solar photo-voltaic (PV) system installed, and of those, only 172 agreed to have one installed. In June 2012, Brian Keating, one of Calgary’s best known naturalists and an official spokesperson for Generate Choice, became the 100th Calgary homeowner to join in the program. "Through a lease program, the panels generate a portion of a home’s energy needs. A set of six panels is a 1.3 kilowatt-hour photovoltaic system that will produce between 1,000 and 1,400 kWh per year. The average home in Calgary uses 625 kWh per month," says Colin Dumais, technology specialist with ENMAX". ENMAX is a wholly owned subsidiary of The City of Calgary. Over the last 11 years, ENMAX has returned approximately $600 million to The City of Calgary. In 2011, over $550 million was invested back into Calgary’s electricity infrastructure to maintain reliability and support future growth. Revenues increased from $2.4 billion in 2010 to $3.1 billion in 2011. In 2011, the company generated net earnings of $184.6 million and paid a dividend in the amount of $56 million to its Shareholder, The City of Calgary (ENMAX 2019:8). ENMAX has been named one of Alberta’s Top 50 employers by Mediacorp. In 2011, the CEO of ENMAX, Gary Holden, resigned after controversial handling of travel expenses that violated the company's ethical guidelines.
