The case for energy efficiencyFast and cheap: technology is already available

“Improving energy efficiency worldwide is the fastest, the most sustainable and the cheapest way to reduce

greenhouse gas emissions and enhance energy security.”(Final statement of G-8 summit, Germany, June 2007)

“Increasing energy efficiency, much of which can be achieved through low-cost options, offers the greatest potential for reducing CO2 emissions over the period to 2050. It should be the highest priority in the short term.”

(International Energy Agency's Energy Technology Perspectives, July 2010)

Reducing losses along the energy chainABB technology helping at every step


Energy efficiency in utilitiesPower generation, transmission and distribution

Power plants consume 5% of the electricity they generate

This can be cut by 10 to 30% by optimizing operations and auxiliary systems using sophisticated control systems and energy-efficient equipment

In transmission and distribution, ABB technologies enable more power to travel over existing networks and reduce power losses


Grosskraftwerk Mannheim, Germany

1,675 MW coal-fired power plant

MV drives, dry-type transformer to control boiler feed pumps

Emissions cut by 10,200 tons/year, revenues increased by $800,000/year

Case studiesPower generation, transmission and distribution

Power Grid Co. of BangladeshFACTS technologies installed in 8 substations, reducing electrical losses by 34 MW

Investment <15% of similar capacity fossil-fuel power plant

Payback time 18 months


Energy efficiency in industryOther industries accounts for 33% of global energy use

Modern control solutions, automation products and electrical equipment run plants productively and efficiently

Key technologies include controls, enterprise software, instrumentation, low-voltage products, drives, motors, robots and turbochargers

ABB’s energy consultants are experts at identifying energy waste


Case studiesIndustry

Saves 5,300 MWh and $260,000/year

Six months investment payback time

ArcelorMittal steel mill, France ABB identified 53 energy-saving opportunities

Savings potential of about $13.9 million/year, including:

Gas savings - $8.3 million

electricity savings - $6 million


Energy efficiency in transportationABB helps ship and rail operators reduce consumption

Azipod ship propulsion system brings savings of 5 to 15%, while turbochargers boost diesel engine output four-fold

In rail, ABB technologies transfer power efficiently from grids to railways, while on board components and complete traction packages increase efficiency


Deutsche Bahn, GermanyNew traction converter developed for first fleet of InterCityExpress trains in just 13 months

Energy consumption cut by at least 12%

Operating and maintenance costs reduced

Case studiesTransportation

Sinorail Bohai Train Ferry Co., ChinaThree new ferries fitted with Azipod power and propulsion solutions

Fuel consumption reduced by ca. 20% vs conventional arrangements

Saving approximately $2.2 million/year


Energy efficiency in buildingsBuildings account for 40% of energy consumed

ABB building control systems adjust temperature, lighting and energy consumption of electric appliances

ABB is also a leading producer of low-voltage, energy efficient devices for building applications

High-efficiency ABB motors and drives cut energy consumption of pumps and fans in heating, ventilation and air-conditioning (HVAC) systems


Case studiesBuildings

State Library of Victoria, AustraliaDrives help control indoor climate

Saving of 1,800 megawatt-hours (MWh) and $160,000 per year

Payback time of 13 months

Museo d’Arte Moderna in Rovereto, Italy

ABB i-bus KNX technology installed

28% energy savings with advanced lighting control systems

Saves 450,000 kilowatt-hours (kWh) per year and cut costs by $112,000/year


Energy efficiency backgroundWhy concentrate on motor driven systems

In the industrial sites, over 65% of the electricity is spent to run motors

Motor installed base by end users are generally old and obsolete(= inefficient)

Machines, Motors and Drives are the technologies with the highest potential energy savings against the

lower investment impact (relatively limited and distributed in time)

smaller impact on the existing plant

easier installation procedures

lower payback times (6 ÷ 18 months compared to 4 ÷ 5 years for cogeneration and 12 years for photovoltaic panels)

Energy appraisals for motor driven systems are relatively simple


Energy efficiency backgroundHow to reduce motor electrical consumption

The electricity demand of motor-drive systems can be reduced by:

Using high-efficiency motors

Proper sizing of the motor to the load requirements

Using variable speed drives to match the speed and torque to the load requirements

Replacing inefficient throttling devices and wasteful mechanical transmissions

Optimizing systems, including the motor-driven equipment, distribution and end-use equipment to deliver the required energy service more efficiently

Proper maintenance and repair

Maintaining acceptable levels of power quality


Energy appraisalTailored to the end user

Energy appraisals as a new offering to our customers

To reduce energy costs, a company should evaluate its energy usage

An energy appraisal is a systematic examination of applications

It includes monitoring of energy consumed before and after the change to ABB high efficiency motors and drives

ABB offers energy appraisals that rapidly determine where and how much energy can be saved
