In addition, as previously contemplated, the IESO plans to introduce a new midstream lighting incentive program in Q4 2023. When this program is launched, most lighting measures, including under both custom and prescriptive streams, will be removed from the Retrofit program. So please note that incentives for custom lighting projects will only be available in the Retrofit program for a limited time.
Applicants will now be able to submit Retrofit applications for custom measures and will no longer be limited by the list of prescriptive measures available in the program. This will enable the program to incent more energy-efficiency measures in non-standard projects that are more reflective of actual operating conditions, and to capture more savings.
An increased incentive rate will be available of $1,200/kW or $0.13/kWh, whichever is greater. The rate for both lighting and non-lighting projects will be the same, while incentives continue to be capped at 50 percent.
In addition, the incentive threshold for custom projects to require a measurement and verification (M&V) plan will be $80,000.
The basis for the incentive for networked lighting controls (NLCs) is changing from square feet of controlled space to estimated kilowatt-hours saved. This change will align the incentive more closely with the way NLC rates are typically calculated in other jurisdictions and to more accurately capture the savings realized. The new incentive rate will be $0.35/kWh, which is an increase in the incentive for most projects.
The incentive cap limit of $1 million per application is being removed for the program. Incentives will continue to be capped at 50% of project costs. This is being removed to enable more larger projects that can deliver significant savings to be incented through the program.
Typically, more electricity is consumed in the greenhouse sector for lighting than for all other electrical end uses (irrigation and circulation pumps, space heating and cooling, etc.) combined.
A new program stream, Retrofit for Greenhouses, is being introduced. In this stream, participants will find common measures used by this sector. In addition to the existing suite of horticultural lighting incentives, a new incentive for advanced lighting controls for greenhouses will be available. This new measure is intended to expand the market opportunity. The incentive level for advanced lighting controls for greenhouses is set at $0.35/kWh.
