If you plan to upgrade 100 amp to 200 amp service, you want a safe, code-compliant result without surprises. This guide explains when a 200 amp panel makes sense, what it costs in Northern Colorado, how permits and inspections work, and how to claim HEAR/HER rebates. We also cover EV readiness, dedicated circuits, and maintenance tips. If you are in Fort Collins, Greeley, Loveland, Windsor, or Longmont, our licensed electricians can assess your panel and handle everything end to end.
Do You Really Need 200 Amp Service?
A 200 amp upgrade expands capacity for today’s electrical loads. If you are tripping breakers, noticing lights dim during appliance startups, or planning high-draw additions, you are a candidate. Common triggers include EV chargers, hot tubs, finished basements, electric ranges, heat pumps, and accessory dwelling units.
What changes with 200 amps:
- More available circuits for appliances and projects
- Better headroom for EV charging and electrification
- Fewer nuisance trips and a safer distribution of load
Local insight: Many Front Range homes built before the 1990s still run on 60 to 100 amps. Adding an EV charger and an electric range can overwhelm those panels. Our team performs a comprehensive inspection of your electrical system, including panels, wiring, outlets, switches, and fixtures, then provides a load calculation to confirm the right size.
Review callout: “Had a new electrical panel installed, very happy with the work! Fast, efficient, and on time.”
Signs Your 100 Amp Panel Is Undersized
Look for these issues before you add more devices:
- Breakers trip when the dryer and microwave run together
- Frequent dimming or flicker when the AC or well pump starts
- Warm breaker fronts or a buzzing panel cover
- Double-tapped breakers or a crowded panel with no spare spaces
- Plans for a Level 2 EV charger or hot tub without a dedicated circuit
Safety matters. The National Electrical Code requires GFCI protection in locations like garages, basements, and outdoor receptacles, and AFCI protection in most living areas. A modern 200 amp panel lets us bring your protection up to current code while expanding capacity.
Review callout: “Bryce did a great job quickly troubleshooting and fixing my electrical issue. Very friendly and professional.”
What Is Included in a 100-to-200 Amp Upgrade
A well-run upgrade is more than swapping a box. Our licensed electricians manage:
- Panel assessment and load calculation
- Permit application with your local Authority Having Jurisdiction
- Utility coordination to pull and reseal the meter
- New 200 amp panel, main breaker, and labeling
- Service conductors sized for 200 amps
- Bonding, grounding, and surge protection options
- AFCI and GFCI upgrades where required
- Dedicated circuits for EV chargers or new appliances
- Final inspection and commissioning
We handle all necessary permits and inspections to ensure your project complies with local regulations. From assessing your electrical load to final charger testing, our team prioritizes quality at every step.
Review callout: “They made the wiring look like a ballet. They even installed a handy new outlet outside because these guys follow code.”
Technical Basics in Plain English
- Service size: Upgrading to 200 amps increases the maximum current your home can safely draw at once.
- Conductors: Typical 200 amp service uses 2/0 copper or 4/0 aluminum service-entrance conductors, sized and installed per code and utility requirements.
- Grounding and bonding: We verify grounding electrodes, bonding jumpers, and water or gas pipe bonding as required.
- Breakers: We replace the main breaker and install new branch breakers as needed to meet AFCI and GFCI requirements.
- Dedicated circuits: EV chargers and many appliances require dedicated circuits for safety and performance.
In Fort Collins, Loveland, Windsor, and nearby communities, the utility or cooperative must coordinate the meter pull. Depending on your address, that may be Fort Collins Utilities, Xcel Energy, or Poudre Valley REA. We schedule the cutover so your downtime is as short as possible.
Review callout: “Fast, efficient, and on time. Helpful in explaining the process and getting the work done quickly.”
Cost Breakdown in Northern Colorado
Every home is different, but here is what drives price:
- Panel location and accessibility
- Length and type of service conductors
- Need for new service mast, meter socket, or riser
- Grounding upgrades and surge protection
- AFCI/GFCI breaker count
- Add-ons like EV charger circuits or subpanels
Typical ranges we see for a full 100-to-200 amp upgrade vary based on scope and utility requirements. The good news for Colorado homeowners is that HEAR/HER rebates may reduce your out-of-pocket cost. These rebates can be applied at the time of installation for qualifying electrical panel upgrades and wiring or circuit additions.
Review callout: “Professional, prompt, and cleaned up after themselves. We will use this service in the future.”
Rebates and Incentives: How HEAR/HER Lowers Your Price
HEAR/HER rebates are available for electrical panel upgrades and wiring or circuit additions. Approved rebates are applied upfront, reducing what you pay at installation. Qualified households can receive up to $14,000 depending on income and household size. The process is straightforward:
- Apply via the Colorado Energy Office HEAR/HER portal
- Send your approval to Origin Plumbing Heating Cooling Electrical
- We submit the rebate reservation and documentation
- The CEO pays the contractor directly after quality-control review
Program fact: The current listing shows an expiration of 2026-03-04. Program terms can change, so we verify eligibility during your estimate. Our team manages the paperwork and ensures your scope matches what the program covers.
Review callout: “Knowledgeable, confident, and they explained everything in a way that made sense.”
Timeline: How Long Does a 200 Amp Upgrade Take?
Most projects follow this sequence:
- Free assessment and written scope
- Permit submission and utility coordination
- Material staging and scheduling
- Panel cutover day with meter pull and inspection
- Final inspection and commissioning
On cutover day, power is typically off for 4 to 8 hours while we replace the panel, land conductors, label circuits, and test protection devices. We plan around your schedule and communicate clearly so there are no surprises.
Review callout: “On time and thorough from start to finish. The entire experience felt smooth and stress-free.”
EV-Ready: Pair Your Upgrade With a Dedicated Charger Circuit
A key component of any charging station installation is a dedicated circuit run from your electric panel to the EV charger location. If your home’s electric panel lacks the capacity to support an EV charger, we’ll recommend a panel upgrade to increase the amperage and improve system performance. During your 200 amp upgrade, we can:
- Add a 40 to 60 amp dedicated EV circuit
- Optimize charger placement to minimize wire runs
- Verify GFCI protection where required by code
- Commission and test the charger for proper operation
You get a cleaner install, better charging performance, and fewer return visits.
Review callout: “They follow code, worked hard in the crawlspace, and still had a good attitude. Give them a call.”
Safety and Code Compliance You Can Trust
We build safety into every step:
- AFCI and GFCI upgrades to reduce shock and fire risks
- Proper labeling so you and future techs work safer
- Surge protection to defend against Front Range lightning and utility spikes
- Panel torqueing and thermal checks
- Full warranty and ongoing support
Regular maintenance is crucial to ensure optimal performance and longevity. Our electricians offer comprehensive electrical maintenance and routine inspections to identify hazards, perform safety upgrades, and extend panel life. That includes GFCI and AFCI testing or installation, outlet and switch repairs, lighting maintenance, and code compliance checks.
Review callout: “Super customer service driven, friendly, and fixed all of our electrical with a smile.”
Commercial and Outbuilding Considerations
If you are upgrading service for a shop, barn, or commercial space, we also design power distribution and panel upgrades for commercial customers. We size feeders for equipment like compressors, welders, and lifts, and we coordinate with inspectors to meet occupancy timelines. For detached garages or ADUs, we can feed a subpanel from your new 200 amp main, keeping loads balanced and compliant.
Review callout: “Helpful in explaining the process and getting the work done quickly.”
