Diesel Generator Replacement - Green Cubes Technology | Lithium-ion Power Systems Manufacturer

Diesel Generator Replacement

Emergency and backup power are integral to the reliable operation of mission-critical systems and facilities, including telecom switching centers, mobile switching centers, and data centers. Diesel Generators have traditionally been used to provide emergency backup power in conjunction with uninterruptable power supplies (UPS). Clean decarbonization and electrification efforts are leading to lithium batteries becoming a viable alternative to diesel generators.

Lithium batteries are the critical pillar in a fossil fuel-free economy and their uses in electric vehicles and stationary energy storage have grown exponentially in recent years, due to technological advances and significant price declines. This is making Lithium backup batteries a potential replacement for Diesel Generators too.

Together with solar photovoltaic (PV) and wind, modular energy solutions are reducing the cost of renewables and making decentralized solutions economically viable, complementing other renewable grid connections. Lithium batteries have become an integrated part of decentralized, often mini or micro, off-grid renewable energy systems, replacing diesel power generators in many remote areas.

Unlike Diesel Generators, when batteries are not used for backup, they can double up as battery energy storage systems (BESS) that help address the imbalances of the grid, generally coming from excess or deficits between the production of electricity and consumption in real time. BESS are typically comprised of an energy storage rack, power conversion and power generation such as diesel or gas generators.

Alternatively, Lithium Ion batteries can be paired with Diesel Generators and allow the generators to run only for short periods each day, charging the batteries up. Then the generators are turned off, and the lithium batteries power the load for 8 or more hours. This ensure the generator is running at peak efficiency and reduces the fuel cost by 50% or more simply using an li ion UPS.

Green Cubes designs and manufacture lithium batteries to meet the exacting requirements of emergency power backup (to replace, or supplant Diesel Generators) and serve as BESS. Green Cubes Lithium Guardian Battery Units (GBUs) can also be used as potential building blocks of a BESS. Green Cubes Lithium ion Systems provide the following benefits over Diesel Generators:

  • Carbon Footprint
    Lithium Ion Batteries offer a clean environment friendly option over Diesel Generators and their harmful CO2 emissions.
  • High efficiency
    Lithium Ion batteries paired with generators improve system efficiency by over 50%
  • Less maintenance
    Lithium Ion batteries can reduce or eliminate diesel generator operating hours.
  • Higher energy density
    Lithium Ion Batteries offer the highest energy density available to store energy.
  • Lower Operating Costs
    Lithium Ion based storage provide a lower operating cost compared to increasing Diesel prices.
  • Improved Revenue Stream
    Lithium Ion Batteries can improve your revenue stream through BESS enabled services.

Customer Ratings and Reviews

Green Cubes is a great company, great engineers, great product. That’s been kind of my number one go to [lithium] battery.

President, Industrial Power Company

The thing I like about Green Cubes is that they have other lines of business outside of material handling batteries, they have been in the lithium world for a long time. I can trust they will likely stay in business

VP, Industrial Battery Company

Green Cubes [differentiates] on its capability to custom design for things like the hardware, the firmware, and inverters. They also have economies of scale because they make battery systems for things like forklifts.

VP, Powered Cart OEM

I am doing some work with them right now. We’re learning their products, and looking at demos. They have good people. They seem like they know the technology well – they say they’re a technology company. I like that they’ve been in the lithium business a long time. I can trust they will likely stay in business.

Sales Manager, Industrial Battery Company

Green Cubes Technology would be my go-to for lithium applications.

Branch Manager, OEM

I’ve told my friends at Green Cubes, I don’t plan on going anywhere. I believe in loyalty.
