30-Second Takeaway
New Zealand company CranePower has introduced the E-Gen mobile energy storage system as an alternative to traditional diesel-powered construction site generators. The system is designed to reduce fuel consumption, lower emissions, and improve power efficiency for tower cranes and other high-demand construction equipment.
CranePower Introduces E-Gen Mobile Energy Storage System
New Zealand-based start-up CranePower has officially launched its new E-Gen battery-based mobile power system for construction sites.
The company says the E-Gen has been developed as an alternative to traditional diesel generators by using battery storage to manage short periods of high power demand while reducing unnecessary fuel consumption.
CranePower claims early deployments across construction sites in New Zealand & Australia and have already reduced fuel costs by up to 85 percent. The launch reflects growing industry demand for lower-emission and more energy-efficient site power solutions.
Crane Hub Team Met CranePower at Bauma 2025
The Crane Hub Global team first connected with CranePower during Bauma 2025 in Munich and has continued following the company’s development since the event.
The New Zealand start-up attracted attention at Bauma for its innovative approach to reducing diesel dependency across crane and construction operations through mobile battery technology and intelligent energy management systems.
E-Gen Designed to Reduce Diesel Generator Dependency
According to CranePower, traditional construction site power systems are often highly inefficient because diesel generators operate continuously even during periods of low energy demand.
Battery System Handles Peak Power Demand
The E-Gen uses battery storage to manage:
Short bursts of high power demand
Peak crane operation loads
Fluctuating site power requirements
The company says the system works alongside either:
Diesel generators
Mains electricity connections
while managing energy sources automatically in real time.
Smaller Generators and Urban Connections Possible
CranePower said the E-Gen may allow sites to:
Use smaller generators
Reduce overall fuel consumption
Connect directly to three-phase urban power supplies
Avoid transformer requirements on some projects
The system is particularly targeted toward:
Tower crane operations
Urban construction sites
Temporary site power applications
Founder Highlights Construction Industry Fuel Inefficiency
Founder Elliot Peacocke said the construction industry has relied on inefficient diesel generator systems for decades.
“Construction has been running on diesel generators for decades, but it’s an incredibly inefficient system,” said Peacocke.
“You’re burning fuel all day to service short bursts of demand. In today’s market, that’s wasteful, expensive, and unpredictable.”
Peacocke previously operated a diesel generator business before launching CranePower in 2021 after identifying opportunities to improve construction site energy efficiency.
Adaptive Power Platform Manages Real-Time Energy Demand
The E-Gen system uses CranePower’s proprietary Adaptive Power Platform
to monitor and manage site energy requirements.
Intelligent Energy Management Reduces Waste
The platform controls:
Power delivery
Peak demand balancing
Battery charge management
Generator integration
According to CranePower, matching energy supply more closely to actual site demand significantly reduces wasted fuel and operating costs.
“Fuel is one of the highest uncontrolled costs on a construction site,” Peacocke explained.
“What we’ve done is remove that dependency and replace it with something far more stable and efficient.”
Compact Design Supports Site Mobility
CranePower said the units have a footprint approximately:
10 percent of a traditional containerised system
The E-Gen can also be:
Delivered using a standard pickup truck
Moved with a standard forklift
Operated in parallel groups of up to eight units
for larger construction projects.
Remote Monitoring Tracks Energy and Emissions Data
Each E-Gen unit includes integrated:
4G remote monitoring systems
allowing operators to track:
Power consumption
Battery charge levels
System temperatures
Total kilowatt-hour usage
The collected data can also be used to estimate:
Diesel savings
Emissions reductions
Site energy efficiency
CranePower said the E-Gen systems are designed for an operational lifespan of approximately 15 years.
Construction Industry Accelerates Shift Toward Low-Emission Power Solutions
The launch of the E-Gen reflects broader industry efforts to reduce:
Diesel consumption
Carbon emissions
Construction site operating costs
Battery energy storage systems are increasingly being integrated into:
Crane operations
Temporary power infrastructure
Hybrid energy systems
Urban construction projects
as contractors seek more sustainable and cost-efficient power solutions.
