Temporary PowerService

We provide generators of varying sizes to match your specific power requirements—from portable units (3-10 kW for small tools and lighting) to mid-size generators (10-50 kW for construction sites) to large tow-behind generators (50-200+ kW for commercial facilities and disaster response). Our team assesses your power needs and recommends the right generator size to ensure adequate capacity without overpaying for unnecessary power. We can also provide multiple units for very large projects or distributed power needs.

Rock Emergency assesses your power requirements by: listing all equipment and tools you need to power simultaneously, calculating total wattage/amperage requirements (including startup surge power), considering duty cycle and usage patterns, evaluating environmental factors (temperature, altitude), and adding safety margin for reliability. We provide a detailed power assessment at no charge and recommend generator sizing that ensures reliable operation without paying for excess capacity. Proper sizing prevents equipment damage from under-powering and saves money vs. over-sizing.

Cost varies based on: generator size and capacity (kW rating), rental duration (daily, weekly, monthly rates—longer terms have better rates), installation complexity (simple connection vs. full distribution panel), fuel costs (diesel or natural gas—we can handle fueling or you provide), delivery distance from our facility, and whether you need operators or just equipment. We provide customized quotes for your specific needs. As a guideline: small portable generators start around $150-300/day, mid-size construction generators run $300-800/day, and large commercial units can be $800-3,000+/day. Monthly rates provide significant savings.

Yes, generators can power HVAC systems, electric heaters, and portable climate control equipment. We also offer portable electric heaters for construction sites, drying operations, and maintaining temperature in cold weather. Important considerations: HVAC systems have high startup power (surge) requirements—we size generators accordingly, continuous runtime is needed for climate control, and fuel consumption is higher when running heating/cooling. We can design temporary power systems specifically for climate control needs during disaster recovery, construction, or when building systems are offline.

Absolutely. Safety is our top priority. All temporary power services meet OSHA safety standards, comply with National Electrical Code (NEC) requirements, follow local electrical regulations and permit requirements, and include proper grounding and overcurrent protection. Our technicians are trained in electrical safety protocols and use only well-maintained, inspected equipment. We provide load calculations to prevent overloading, install proper distribution panels when needed, and can coordinate with local authorities for permits and inspections.

Setup time depends on complexity and current demand, but we prioritize rapid deployment. Simple portable generator setups can be done within hours—we deliver, position, fuel, start, and connect. Complex installations with distribution panels and multiple circuits may take 1-2 days. Large-scale disaster response power can take 2-5 days including permitting and utility coordination. We maintain ready-to-deploy equipment and can expedite setups for emergencies. Call us with your timeline and we'll work to meet your needs.

We offer flexible fuel options. We can: deliver generators pre-fueled and ready to run, provide ongoing fueling service for long-term rentals (scheduled refueling visits), install fuel monitoring systems for large generators, or you can handle fueling yourself (we'll show you how and provide specifications). Most generators use diesel fuel (easy to source and store safely). Some applications may use natural gas or propane. We discuss fuel logistics during your power assessment and create a plan that works for your situation and budget.

All rental equipment is well-maintained and inspected before deployment, but if issues occur we provide: 24/7 technical support by phone, emergency repair service (we dispatch technicians), and replacement generators if repair isn't immediate. Our goal is zero downtime for your operation. We also offer preventive maintenance during long-term rentals to prevent breakdowns. Rental agreements include equipment support—you're never stranded without power. For critical applications, we can provide redundant backup generators for extra reliability.
