LGD Electric / Panel Upgrade vs Load Management
EV charger: panel upgrade or load management?
Two code-compliant ways to add a Level 2 charger when your panel is short on capacity, compared on cost, timing, rebates and what they mean for future upgrades.
If your panel is short on capacity for a Level 2 EV charger, there are two code-compliant routes: upgrade the electrical service (usually 100A to 200A), or install an EV energy management system (EVEMS, sometimes called a load management or power management device) that slows or pauses the charger when the rest of the house is drawing a lot of power. The right answer depends on your load calculation and on what else you plan to electrify.
Side-by-side comparison
| Load management (EVEMS) | Service upgrade to 200A | |
|---|---|---|
| Typical cost (LGD) | $3,500-$5,500 for the charger install including the load management device | $1,200-$3,500 for the charger, plus $3,500-$7,000 all-in for the upgrade |
| BC Hydro service change | Not needed | Needed; typically 4-8 weeks in LGD's experience |
| Extra rebate | Up to $200 for an eligible power management device (BC Hydro charger rebate top-ups) | None specific to the upgrade |
| TSBC permit (where TSBC issues it) | Based on job value, e.g. $335 for a $2,501-$5,000 job in 2026, $352 in 2027 | $332 for a single-family upgrade up to 200A in 2026, $349 in 2027 |
| Charging speed | Full speed most of the time; slows or pauses when the house is busy | Full speed whenever the charger circuit allows |
| Room for a heat pump, induction range or second EV later | Little or none | Yes |

Why load management is allowed
The BC Electrical Code normally counts an EV charger at 100% of its load when sizing a service. Technical Safety BC's bulletin explains two relaxations: Rule 8-106 8) lets the calculation use the utility's measured peak demand over the last 12 months or more, and Rule 8-106 11) relaxes the EV load when an EVEMS monitors the service, feeders and branch circuits and controls the charger. The relaxation does not apply if the device does not monitor the service. The EVEMS must also be approved equipment installed to the manufacturer's instructions (TSBC information bulletin on EVSE and EVEMS).
When load management is the better choice
- One EV, mostly charged overnight when the rest of the house is quiet.
- A 100A service in good condition, with no plans for a heat pump or induction range.
- You want the charger working soon, without waiting for a BC Hydro service change.
- You want to avoid the cost of a new mast, meter base and panel.
When a service upgrade is the better choice
- You are also adding a heat pump, an induction range, a hot tub or a secondary suite.
- Two EVs, or long daily drives that need a full charge every night.
- A 60A service, or a panel that should be replaced anyway, such as a Federal Pioneer Stab-Lok.
- The load calculation shows too little headroom even with load management.
How LGD decides with you
We start with the load calculation, using BC Hydro's measured peak demand where it is available, then price both routes when both are code-compliant. See EV charger installation, the 200A panel upgrade cost guide and EV charger permits in BC.
FAQ
Do I need a 200A panel upgrade for an EV charger?
Not always. If the load calculation shows too little capacity, an EV energy management system that monitors the service and controls the charger can let the charger share capacity without a service upgrade, as allowed under BC Electrical Code Rule 8-106 11).
Is an EV load management device cheaper than a panel upgrade?
Usually. LGD's typical charger install with a load management device is $3,500-$5,500, compared with $1,200-$3,500 for the charger plus $3,500-$7,000 all-in for a 200A upgrade. An eligible power management device can also earn a BC Hydro rebate of up to $200.
Will load management slow down my EV charging?
Only when the rest of the house is drawing a lot of power. The device slows or pauses the charger at those times, which matters little for most overnight charging.
Can I add a heat pump later if I use load management for my EV?
Usually not without revisiting the service. If a heat pump, induction range or second EV is on the way, a service upgrade is often the better long-term choice.
Do both options need an electrical permit?
Yes. Both need an electrical permit from your municipality or Technical Safety BC, and a service upgrade also needs BC Hydro to change the service.
