Alternative Generation Safety
Renewable Generation Safety
Any system that produces even small amounts of electricity can be potentially dangerous, creating the possibility of electrocution and fire hazards. Improperly installed systems will create serious safety hazards to property owners, their friends, family, employees and local electrical distribution company workers.
For more information on Solar Photovoltaic Systems, please review the presentation below:
The below guideline is intended to simplify and provide basic advice to home, farm and business owners who are considering the installation of distributed generation systems. Please click on the PDF below to review the guideline.
The Process Guideline below is intended to provide information regarding ESA process around the installation of Renewable Energy Systems greater than 10kW (FIT installations). The process has been developed by ESA to help avert costly delays in parallel generation projects. Please click on the PDF below to review the guideline.
New Rule 50-014 had been introduced in Canadian Electrical Code 2012 to require arc fault protection (AFP) for dc circuits on or penetrating buildings and operating at 80V dc or higher;
This requirement had been postponed in Ontario until May 2013;
ESA will extend the postponement of Rule 50-014 enforcement from May 2013 until January 1st, 2014
The postponement is providing more time for manufacturers, designers and contractors to come up with more options and products to achieve compliance, such that this new requirements will not result in restricting the market to a couple of manufactures/products.
In Ontario, in addition to cables permitted by OESC, PV cables approved to UL Standard, UL 4703 Outline of Investigation for Photovoltaic Wire is an acceptable wiring method within a PV array.
The permission for using PV cables approved to UL standards will expire on January 1, 2013. Starting January 1, 2013, all wiring used for Photovoltaic system installations are required to be approved to Canadian Standards.
There is a new Canadian standard C22.2 No 271 for Photovoltaic Cable. Cables approved to this standard (RPVU & RPV) are now available in the market.
For More Information Please Refer to :
In Ontario, in addition to DC disconnect switches approved as per Rule 2-024, DC switches approved to UL standard, UL 098B “Outline of investigation for enclosed and dead-front switches for use in photovoltaic systems” are acceptable as disconnecting means for PV and other renewable energy systems.
DC switches approved as per Rule 2-024 are required to have a specified DC wiring diagram for the switch.
Inverters used in renewable energy installations are required to be certified to appropriate Canadian standards and bear a certification mark accredited by Standards Council of Canada and recognized in Ontario, see Bulletin 2-7-*. No other marking in addition to the certification mark is required to identify that a product meets the applicable standard. Inverters that are to be interconnected with a supply authority system shall be marked as "UTILITYINTERCONNECTED" or equivalent.
Inverters marked as "UTILITY-INTERCONNECTED" or equivalent are not permitted to be field evaluated
Before your solar, wind or other renewable energy generator can be connected to the electrical system it must be inspected and approved by the Electrical Safety Authority (ESA). The OESC requires an application for Inspection to be submitted by the contractor doing the work. ESA recommends that all electrical work be done by a qualified electrical contractor/electrician. Installing an alternative generation system is beyond the ability of most do it yourself projects.
Once the installation is complete and meets the requirements of the OESC a connection authorization will be sent by the ESA to the Local Distribution Company.
FAQ’s About Electrical Inspection
1. Why do I need to have an Inspection?
2. How to apply for an electrical inspection?
3. What are the fees for electrical inspection?
4. What happens if my inspection does not pass?
Once the installation is complete and meets the requirements of the OESC a connection authorization will be sent to the Local Distribution Company.
Green Energy Act & Renewable Energy
The Green Energy Act was introduced on May 14,2009 by the Ontario Government. The historic Green Energy Act, is intended to attract new investment, create new green economy jobs and better protect the environment.
Once in force, the Green Energy and Green Economy Act (GEA), as well as complimentary policy and regulations, will provide the government with the necessary tools to ensure Ontario's place as North America's renewable energy leader, and to create a culture of conservation, assisting homeowners, government, schools and industry in embracing lower energy use.
The Feed In Tariff program is offered by the Ontario Power Authority (OPA) to offer home, farm and small business owners who are considering the installation of alternative forms of electricity generation such as solar and wind and connecting them to run parallel with the Local Distribution Company (LDC).
The Electrical Safety Authority plans to participate in many areas of the GEA and initially will play a role in the Feed-In Tariff program.
What is the Feed- In Tariff Program & Renewable Energy
Two Types of Renewable Energy Installations
A Feed-In Tariff refers to the specific prices paid to renewable energy suppliers for the electricity produced by the generating facility.
How do I participate in the Feed In Tariff Program?
There are three main steps to participating in the Feed-In Tariff program.
