Existing service
The current service may already have appropriate capacity after the applicable calculation.

A 200 amp panel is only part of the power story.
Do you need 200 amp service? Maybe. A new panel, more utility capacity and load management solve different problems. See the whole service path before you pay for the wrong one.

Start with what you know
What service does your home have?
Choose the number shown on the largest main breaker that is already visible. Never remove a panel cover or touch electrical equipment.
Find the right starting point
Three questions before the quote.
Choose the guide that matches what you know today. Each one leads to the evidence a contractor will need.
01 / Identify
What service does my home have?
Use visible clues safely and know when the number needs professional verification.
Read the identification guide →02 / DistinguishPanel change or service upgrade?
See why a new panel alone may leave the available service capacity unchanged.
Compare the scopes →03 / ScopeWhat belongs in the quote?

What are you planning?
One new appliance rarely answers the capacity question by itself. Start with the project, then account for what the home already uses.

The panel is one stop in a longer journey.
Follow the connection from utility supply to a room in the house. Select each stage to see what must be verified before a service change is scoped.
Stage 01 / 04
Utility supply
Drop or lateral, transformer and metering supply.
- Who to ask
- Typically the serving utility
Equipment arrangements and ownership boundaries differ by property and utility. Have a qualified contractor and the serving utility confirm the actual path.
Quote scope checklist
Compare quotes line by line.
Two quotes for “a 200 amp upgrade” can cover very different work. Ask each contractor to state every item as included, excluded or not required.
What drives upgrade cost- 01Utility
Is utility work included, excluded or to be arranged by the owner? Who submits the utility request?
- 02Meter
Is the meter base reused, relocated or replaced?
- 03Service conductors / feeder
Are service conductors or feeders replaced, and over what route?
- 04Panel
Is the panel replaced, and is it a like-for-like or a service-capacity change?
- 05Circuits
Which new circuits are included, for which equipment?
- 06Permits + inspections
Who applies for permits and books inspections? Are fees included?
- 07Restoration
Is drywall, stucco, trenching or landscaping repair included or excluded?
- 08Closeout
What documents are handed over (permit closeout, load calculation, panel directory)?
Three possible paths
The honest answer may be retain, manage or upgrade.
Professional assessment determines which path fits the home, equipment and jurisdiction.
Load management
An approved system may control suitable loads within the capacity already available.
Service upgrade
Additional permanent capacity may fit the project and longer-term electrification plan.
Calgary electrical activity
Public evidence, with the limits left visible.
Open Calgary publishes daily electrical permit inspection data. We count permits separately from inspection events and do not claim it identifies every 200A upgrade.
See data and methodologyThe project record
A new panel should come with a clear paper trail.
Ask the contractor to show how the decision was made, which parts are changing and how the completed work will be documented.

Straight answers
Common capacity questions.
Do I need 200 amp service?+
Not automatically. Existing demand, planned loads, panel configuration, service equipment and management options determine what should be assessed.
Is 100 amp service enough for an EV charger?+
It can be. Charger output, existing demand and approved charging controls or energy management can change the answer.
Does replacing the panel increase amperage?+
Not by itself. A panel replacement and a service-capacity increase are different scopes.
Can load management avoid a service upgrade?+
Sometimes, for suitable loads, equipment and jurisdictions. It is not a universal alternative.
Do I need a permit?+
Electrical alterations commonly require the applicable permit, but the authority and exact process vary by location and scope.
