Okay, this is a tough situation, but let's brainstorm some alternative power solutions for your trailers, considering the lack of existing electrical infrastructure. You're right; running gas generators non-stop is expensive. Here's a breakdown of potential options, from most to least likely to be practical, along with their considerations

1. Solar Power (Most Likely Viable, with Caveats)
How it Works

Solar panels convert sunlight into electricity, which is then stored in batteries for use.

Why it Might Work

Solar technology has improved significantly and can be a good solution for powering trailers with moderate electrical needs. A hybrid system with a generator for backup is viable.

Things to Consider



Sunlight Availability

Crucially, how much direct sunlight does the area receive daily? Consider shadows from the building or surrounding trees. If sunlight is limited, this may be a poor choice.

Power Needs of the Trailers

What appliances are running (refrigerators, microwaves, heaters, air conditioners, computers, lights, etc.)? This determines the size of the solar array and battery bank needed. Estimate usage carefully and be realistic. Reduce energy usage as much as possible.

Cost

Initial investment can be high, but it has long-term cost benefits over a gas generator.

Portability & Scalability

You need a system that's relatively easy to set up and move as needed. Portable solar panels with pre-wired battery systems are available. Start small and expand if needed.

Battery Storage

The battery bank is essential for running appliances at night and during cloudy days. Lithium-ion batteries are more expensive but offer longer lifespan and better performance than lead-acid.

Expert Consultation

Crucially, get a professional solar installer to assess your site, needs, and recommend a correctly sized system. They can also factor in local building codes and permitting requirements.

Hybrid Option

A "solar-plus-generator" hybrid system can be the most cost-effective. Solar covers the bulk of the power, and the generator kicks in automatically only when battery levels are low or during periods of high demand.

2. Propane Generators (Possible, but with Caveats) How it Works

Generators that run on propane, providing AC power.

Why it Might Work

Propane can sometimes be cheaper than gasoline (depending on local prices). Propane generators are generally quieter and produce fewer emissions than gasoline generators.

Things to Consider



Cost

Propane can be cheaper than gasoline, but price fluctuates.

Availability

Can you easily get propane delivered to the site?

Storage

Requires propane tanks and proper storage procedures.

Generator Sizing

Similar to gasoline, you need to size the generator to handle the total load of all appliances running simultaneously.

Safety

Propane is flammable; tanks must be stored safely and according to regulations.

Permitting

Check for local restrictions on propane storage and generator use.

3. Negotiate with the Client (The "Softest" Approach) How it Works

A direct discussion with the client regarding the unforeseen power costs.

Why it Might Work

If the contract didn't explicitly address trailer power, and the use of generators is a direct result of the site conditions they imposed, they might be willing to contribute to the cost.

Things to Consider



Contract Review

Carefully review the contract language regarding site conditions, utilities, and unforeseen circumstances.

Documentation

Document all generator fuel costs, hours of operation, and the lack of alternative power sources provided by the client.

Professional Communication

Approach the client with a clear explanation of the situation, the financial impact, and a proposed solution (e.g., a change order to cover generator costs or explore alternative power options jointly).

Legal Counsel

If the client is unwilling to negotiate, you may need to consult with an attorney to understand your contractual rights.

4. Large Battery/Inverter System (Less Likely, but Possible for Limited Needs) How it Works

A bank of batteries is charged off-site (or using a small generator infrequently) and used with an inverter to provide AC power.

Why it Might Work

Could be feasible for limited power needs like lights, phone charging, and small electronics. Eliminates generator noise and emissions on-site.

Things to Consider



Battery Capacity

Requires a substantial battery bank to provide sufficient power for even basic needs.

Inverter Size

The inverter must be large enough to handle the peak load of the appliances.

Charging

Requires a reliable way to charge the batteries.

Logistics

Transporting and managing large batteries can be cumbersome.

5. Wind Power (Generally Impractical for This Situation) How it Works

Wind turbines convert wind energy into electricity.

Why it's Unlikely



Wind Availability

Requires consistent and sufficient wind. Construction sites are often sheltered.

Turbine Size

Small turbines typically don't produce enough power for trailers.

Regulations

Zoning and permitting for wind turbines can be complex.

Set-Up

Installation and maintenance can be challenging.

Action Plan & Recommendations


Quantify Power Needs

Make a detailed inventory of all electrical devices in the trailers and their wattage. Estimate daily usage hours. This is critical for evaluating any alternative power solution.2.

Assess Sunlight

Monitor the site for a few days to determine sunlight availability. Note any shading from the building or other objects.3.

Get Solar Quotes

Contact at least three reputable solar installers for site assessments and quotes for portable or semi-permanent solar power systems. Ask about hybrid options (solar + generator backup).4.

Explore Propane

If propane is significantly cheaper than gasoline in your area, research propane generator options and fuel delivery services.5.

Document Everything

Keep meticulous records of generator fuel costs, hours of operation, and any attempts to find alternative power sources.6.

Negotiate with the Client

Present the client with the documented costs and the proposed solar or propane solutions. Emphasize that these are more cost-effective and environmentally friendly options.

Important Safety Note: Any electrical work should be performed by qualified electricians to ensure safety and compliance with local codes.* Follow all safety precautions when handling generators, fuel, and batteries.This is a challenging situation, but with careful planning and research, you can find a more cost-effective and sustainable way to power your trailers.
