When your panel is near capacity, a smart EV Energy Management System lets you charge without a costly upgrade. We install DCC-9, DCC-12, and Black Box EVEMS devices, along with ChargePoint, Grizzl-E, and JuiceBox load sharing, using current transformer monitoring to shed the EV load only when the household peaks. Every install is compliant with OESC Rule 8-106. The idea is simple. Your service has a maximum, but your house almost never draws it. Peak demand happens for an hour or two around dinner when the oven, the dryer, and the air conditioner overlap. An EVEMS watches the main conductors through CT clamps, and when the total approaches the limit it pauses the charger. Once demand falls, charging resumes. That behaviour is why the code allows the EV load to be treated as non-coincident rather than counted at full value in the service calculation. It is not a workaround. It is a documented, inspected, code-recognized method that saves a lot of GTA homeowners several thousand dollars. ## When does EVEMS beat a panel upgrade? For a large share of the 100A homes across Scarborough, East York, Mississauga, and the older Toronto core, EVEMS is genuinely the right answer. A DCC-9 at $500 to $800 CAD installed alongside your charger does what a $2,500 to $4,500 CAD panel upgrade would have done, for the specific problem of adding one EV. It is the wrong answer in three situations. If your service is already strained without the car, adding shedding logic to a service that is short on capacity year-round just moves the problem. If you are planning electric heat, a heat pump, a pool, or a hot tub, the electrical panel upgrade [/electrical-panel-upgrade/ →](/electrical-panel-upgrade/) you defer today gets bought next year anyway. And if your panel has capacity but simply no free breaker spaces, a dedicated subpanel [/subpanel-installation/ →](/subpanel-installation/) at $1,500 to $2,800 CAD is the cleaner fix. We run the OESC Section 8 load calculation before quoting, so the recommendation comes from your numbers rather than from what is convenient to sell. ### Common problems we solve - **“You need a $4,000 panel upgrade.”** Often untrue for a single Level 2 charger on a 100A service. - **Nuisance shedding.** A controller sized or configured wrong sheds constantly. We test under real household load. - **Full panel, plenty of capacity.** That is a subpanel problem, and we say so rather than selling a controller. - **Two EVs on one service.** Native load sharing plus an EVEMS above it handles both cars cleanly. - **Inspector questions.** The Rule 8-106 calculation goes on the permit so the ESA inspection is straightforward. ## What does the install involve? The controller mounts beside your panel. CT clamps go around the main service conductors so the device sees total household draw, and the EV charger circuit is routed through the controller so it can interrupt the charger without touching anything else in the house. Then we test it properly. We load the house deliberately, watch the controller drop the charger at the threshold, and confirm it restores charging when demand falls. A datasheet says it should work. A clamp meter says it does. Where your charger supports native load sharing, we may not need a separate controller at all. ChargePoint Home Flex, Grizzl-E, JuiceBox, and Tesla Wall Connectors [/tesla-wall-connector-installation/ →](/tesla-wall-connector-installation/) can divide current between units directly, which is often the cheapest path for a two-charger household. The ESA permit is filed, the inspection is booked, and the Certificate of Acceptance comes to you. That documentation matters twice: once for your insurer, and again for your Home Renovation Savings rebate claim [/ontario-ev-rebate-filing/ →](/ontario-ev-rebate-filing/) , which we file on your behalf. ## What does it cost across the GTA? An EVEMS device installed alongside your Level 2 charger runs $500 to $1,200 CAD. A standalone retrofit on an existing charger runs $700 to $1,500 CAD because the circuit has to be reworked. Native charger load sharing, where your equipment supports it, is $300 to $700 CAD to configure and commission. Against a $2,500 to $4,500 CAD panel upgrade, the arithmetic usually speaks for itself. But the honest version is that it depends entirely on your load calculation, and we would rather quote you the upgrade you actually need than the device you would rather hear about. Transparent Pricing ## How much does load management cost in Toronto? $500 to $1,200 CAD (CAD, add-on to a charger install). You get a fixed written quote with the ESA permit fee itemized before any work begins. ### DCC-9 Add-On $500 to $800 - DCC-9 demand charge controller - CT clamp monitoring on the main - OESC Rule 8-106 compliant - Installed with your charger Get Your Free Quote [/contact/ →](/contact/) Most Common ### DCC-12 or Black Box $800 to $1,200 - Higher-capacity EVEMS device - Suits larger continuous loads - Full load calculation documented - ESA permit and inspection Get Your Free Quote [/contact/ →](/contact/) ### Charger-Native Load Sharing $300 to $700 - ChargePoint, Grizzl-E, or JuiceBox sharing - Configured across multiple units - No separate controller needed - Commissioned and tested Get Your Free Quote [/contact/ →](/contact/) Pricing is for the device and its installation as an add-on to a Level 2 charger install.

That is the whole reason customers send us their neighbours. ### Rule 8-106 compliance documented EVEMS is explicitly permitted under the Ontario Electrical Safety Code. We document the calculation so the inspector agrees. ### Shed behaviour actually tested We load the house and confirm the controller drops the charger when it should, rather than assuming the datasheet is right. ### Right device for the load DCC-9, DCC-12, Black Box, or native charger load sharing. The load calculation picks it, not what we have on the van. ### Works with your charger brand ChargePoint Home Flex, Grizzl-E, JuiceBox, and Tesla units all integrate, either natively or through the controller. ### Upgrade path preserved If you add a heat pump or a second EV later, the wiring we leave supports moving to a full upgrade without rework. Process ## How does load management work? Four clear steps, with the ESA permit and inspection built into every one of them. 01 ### Capacity Conversation Tell us your service size and what else is electric in the house. We flag on the call whether EVEMS is likely to work for you. 02 ### Load Calculation An OESC Section 8 calculation confirms how much headroom you have and which device class suits the load. 03 ### Device Install The controller is mounted, CT clamps fitted on the main conductors, and the EV circuit routed through the device. 04 ### Test and Document We test the shed behaviour under real load, book the ESA inspection, and hand over the Certificate of Acceptance.

They installed a DCC-9 load management device instead and I charge overnight with no issues. Saved me thousands." Priya S. Mississauga > "100A panel, no room. They installed a DCC-9 and the charger has worked every night since. Half the price of the upgrade another company quoted." Nadia H. Agincourt, Scarborough > "Older home, tight panel. Load management device instead of a full upgrade, which saved us a lot." Alan W. Mill Pond, Richmond Hill FAQ ## Load Management questions, answered How much does a load management system cost in Toronto? As an add-on to a charger install, an EVEMS device runs $500 to $1,200 CAD depending on the device class. A standalone retrofit on an existing charger runs $700 to $1,500 CAD. Compare that against $2,500 to $4,500 CAD for a 100A to 200A panel upgrade and the appeal is obvious. What is an EVEMS and how does it work? An EV Energy Management System monitors your total household draw through current transformer clamps on the main service conductors. When the house approaches its service limit, the controller pauses or throttles the EV charger, then restores it once demand drops. Your car simply charges a little later in the evening, and the service is never overloaded. Is load management allowed by the Ontario Electrical Safety Code? Yes. OESC Rule 8-106 explicitly permits an approved energy management system to be used so that the EV load does not have to be counted at full value in the service calculation. That is the code basis every compliant EVEMS install in Ontario relies on, and we document it on the permit. Will my car charge slower with load management? Not usually, and not in a way that matters. Shedding only happens when the household is near its service limit, which for most homes is during dinner, not at 2am. Overnight charging is essentially unaffected, especially on an Ultra-Low Overnight rate where you would be charging then anyway. Which EVEMS devices do you install? DCC-9 and DCC-12 demand charge controllers, Black Box EV devices, and SimpleSwitch style controllers, plus native load sharing built into ChargePoint Home Flex, Grizzl-E, JuiceBox, and Tesla Wall Connectors. The load calculation determines which class of device suits your service. Can EVEMS replace a panel upgrade in every case? No, and we will tell you when it cannot. If your service is genuinely undersized for how you live, with electric heat, a pool, or a second EV coming, an upgrade is the right answer. EVEMS solves a capacity headroom problem. It does not solve a fundamentally undersized service. Does load management work with two EVs? Yes. Two chargers can share the available current through native load sharing, and an EVEMS controller sits above that to protect the main service. Households with two Teslas or a Tesla plus a J1772 vehicle are a common setup for us. Do I still need an ESA permit for a load management install? Yes. The EVEMS device and the EV circuit are both permitted work. We file the permit, book the inspection, and hand over the Certificate of Acceptance, which is also what makes the Home Renovation Savings rebate claim valid.
