Power That Keeps Your Business Running

A panel upgrade replaces your breaker panel and distribution system but uses your existing service capacity from the utility. A service upgrade increases the actual power coming into your building from PSEG Long Island, which requires utility coordination and often means upgrading the service entrance, meter, and panel together. If your building has 100-amp service and you need 200 or 400 amps, that's a service upgrade. If your service capacity is adequate but your panel is outdated or you need better distribution, that's a panel upgrade. We calculate your total load to determine which you actually need. Service upgrades cost more and take longer because they involve utility coordination, but they're necessary when your building's total capacity is insufficient for your operations.

The actual installation typically takes 6-12 hours depending on panel size and complexity, but the full process from evaluation to final inspection usually spans 4-6 weeks. That includes time for load calculations, engineering if needed, permit approval from Suffolk County (typically 20-30 business days), utility coordination if you're upgrading service, and scheduling the inspection. The power shutdown during installation is usually 4-8 hours, which we schedule during your slowest period or after hours to minimize business impact. For businesses that can't afford any downtime, we can sometimes phase the work or install temporary power, though that adds complexity and cost. The permit and inspection timeline is the longest part, not the actual installation work.

Modern panels reduce energy waste through improved power distribution and lower resistance losses, typically cutting waste by 5-8% compared to older systems. That translates to real savings for businesses with high electrical demand. The bigger savings often come from what the new panel enables - you can install energy-efficient equipment that your old panel couldn't support, add smart monitoring to track usage, and eliminate the inefficiencies caused by voltage drops and overloaded circuits. Properly balanced 3-phase power distribution also reduces energy consumption in motors and HVAC systems. While the panel itself isn't a huge energy saver, it's the foundation for running a more efficient operation. Most commercial clients see the real return through reduced downtime, equipment longevity, and the ability to operate without constant electrical problems eating into productivity.

Yes, we handle all permitting through Suffolk County and coordinate required inspections as part of the service. That includes preparing the documentation, submitting applications, scheduling inspections, and making sure everything passes the first time. Suffolk County requires permits for panel upgrades and service changes, and PSEG Long Island requires inspections before energizing upgraded services. We're familiar with local requirements, code enforcement expectations, and what inspectors look for. You receive copies of all permits, inspection approvals, and completion documentation for your records. This paperwork is important for insurance coverage, future property sales, and proving code compliance if questions ever arise. Trying to do this work without proper permits creates liability issues and can void your insurance if there's ever a claim related to electrical problems.

Most commercial panel upgrades require a power shutdown of 4-8 hours for the actual installation work, not days. We schedule this during your slowest period, after hours, or on weekends to minimize impact. For businesses that absolutely cannot shut down, we can sometimes install temporary power, phase the work across multiple shorter shutdowns, or coordinate with your backup generator if you have one. The key is planning ahead - rushed jobs create problems and safety risks. We walk through your operation, understand what can't go down, and develop a plan that works. Some businesses choose to close for a day rather than deal with partial power or temporary setups. Others need us there at 6 PM on a Saturday. We accommodate what works for your operation, but there will be some shutdown time for safety reasons when we're working with your main panel.
