We all know the benefits of accessing clean, renewable solar energy for construction sites, including lower running costs, lower emissions and quieter operations. But we also know the drawbacks, too. Solar powered generators are all very well when the sun is shining, but for 24-hour operations, winter working and sites with fluctuating energy demands, you need a more reliable, dependable energy system.

This is where battery energy storage systems, or BESS solutions, really come into their own. As part of your renewable energy plans, BESS solutions can be used to create battery powered generators with all the versatility, reliability and savings you need, while still allowing you to play your part in protecting the environment.

What is a Battery Energy Storage System (BESS)?

A BESS is an advanced battery system designed to store electrical energy when sources such as solar powered generators, are working, and then release it later when these sources are not available. Battery powered generators like this can also be used to deal with peaks of demand that exceed the power from your solar cells or other generation methods.

Think Hire offers a range of battery powered generators to match different demands, from the SiteGrid X100, providing 102kWh at 100kVA, to the SiteGrid X500, which delivers 564kWh of energy at 500kVA. Each one is carefully managed by our AI-assisted Think Energy Panorama, giving you complete control from distribution to diagnostics, 24 hours a day.

How BESS Battery Powered Generators Work: From Peak Shaving to Hybrid Power

There are a number of benefits to installing a BESS solution as part of your site energy system, including:

• Peak shaving – smoothing demand peaks and troughs through smart energy management

• Load shifting – allowing periods of high consumption outside of periods of high generation 

• Reduced costs – maximising your fuel-free solar energy production and reducing dependence on diesel-fuelled back-up generators

• Always on – storing solar power during generation for use 24/7, smoothing out fluctuations in solar energy generation

• Hybrid energy friendly – storing energy generated from multiple sources, including solar and diesel generators

• Resilience – providing dependable back-up energy storage in the event of an emergency or power outage

BESS vs. Diesel Generators: A Head-to-Head Comparison

Like many construction sites, you probably still get most of your energy from traditional generators, so why should you change to battery powered generators? Here are some of the benefits of BESS battery powered generators vs diesel generators for your construction site power:

Battery powered generators

• Low fuel costs

• Silent operation

• No emissions

• 24/7 power

• Few moving parts

• Solar power is constant

Diesel generators

• High fuel costs

• Very noisy

• Multiple greenhouse gases

• Only when running

• Multiple engine parts

• Fuel prices fluctuate

Choosing the Right BESS Solution for Your Construction Project

Here at Think Hire, we can work with you to design the optimum battery powered generator system for your site. Our energy experts will pair the latest solar technology with clean-burning back-up generators and reliable BESS solutions to deliver cost-effective, environmentally friendly power that matches demand even at peak times.

You can choose from four different BESS solutions as part of your battery powered generator, all available for sale or hire, and you can scale them up for larger sites by combining multiple units.
