FITs
A tariff is a traditional term that describes a utility price structure. Feed-in refers to a price that is paid to energy producers that feed their electricity into the energy grid system. A feed-in-tariff (FIT) provides three key provisions to renewable electricity generators: a guaranteed grid connection, a long term contract, and a fixed price sufficient for a reasonable return on investment. The simplicity, fairness, and stability of the FITs help maximize the benefits of Ontario’s push towards a cleaner, greener energy system.
The proposed FIT prices for solar PV projects have been set at:
| Renewable Fuel | Capacity Range | Proposed Price (¢/kWh) |
| Rooftop or Ground Mounted Solar PV | ≤10kW | 80.2 |
| Rooftop Solar PV | >10kW ≤250kW | 71.3 |
| Rooftop Solar PV | >250kW ≤500kW | 63.5 |
| Rooftop Solar PV | >500kW | 53.9 |
| Ground Mounted Solar PV | ≤10MW | 44.3 |
Under a feed-in-tariff, the power producer is paid a premium for every kilowatt-hour generated. Since the project is an investment, Rooftop Kilowatts will design and size the system to maximize the homeowner’s rate of return.
Green Energy Act
Ontario set to be a global leader in renewable energy
The Green Energy Act, 2009 (GEA) was introduced to the Ontario Legislature on February 23, 2009 and was passed into law on May 14, 2009. The vision outlined by the legislation is to make Ontario a global leader in the development of renewable energy by providing clean distributed energy and conservation, creating thousands of jobs, economic prosperity, energy security, and climate protection. The purpose of the legislation is to facilitate the development of a green economy that protects the environment while streamlining the approvals process for renewable projects, mitigates climate change, engages communities and builds a world-class green industrial sector.
One of the major goals of the legislation is to provide a simpler, more comprehensive policy that procures renewable energy development, but at a lower cost and with greater economic and social benefits, like local ownership. To achieve these policy goals the Act proposes the introduction of feed-in-tariff contracts.
