ISO 50001 Management System Standard for Energy

In February 2008, the ISO approved the establishment of a new

project committee (ISO/PC 242 –Energy Management) to develop

the new ISO Management System Standard for Energy. The purpose

of the standard is to :

?assist organizations in making better use of their existing energy

consuming assets

?facilitate benchmarking, measuring, documenting, and reporting on

energy efficiency related data

?facilitate communication on the management of energy resources

?promote energy management best practices and reinforce good

energy management behaviors

?provide a framework for promoting energy efficiency throughout the

supply chain.

?Facilitate energy management improvements in the context of GHG

emission reduction projects.

It is expected that the new standard will be compatible with key

management standards like ISO 9001 for quality management and

ISO 14001 for environmental management (e.g. it will be based on

Plan-Do-Check-Act approach). According to estimations the standard

could influence up to 60 % of the world’s energy use. ISO 50001 is

planned to be published by the Q3 2011.

New technology helping at every step

Reducing losses along the energy chain

80% of energy is lost

New technology can

reduce losses by 20-30%

Energy Efficiency

§Attempts to reduce system losses are driven by environmental

factors.

§Transmission and distribution systems tend to lose about10

percent of the electricity they transport.

§Approximately40 percent of those losses occur in the distribution

system.

§Losses of more than30 percent are estimated for developing

countries

§Technical losses are rarely above20 percent. Technologies such

as high-quality transformers and reactive power compensation

can reduce them to5 to 7 percent.

§It is not only utilities that are keen to reduce losses. Electrical

energy savings have a direct impact on the bottom line of

industrial plants, commercial businesses and households.

§This drives the demand for energy efficient electrical equipment

like motors, drives and consumer appliances.

What and how we response

§energy efficiency is all about customer solutions

§It begins with understanding customer needs and what

keeps them awake at night

§utility customers are focusing more and more on the

energy efficiency of their entire value chain

§New technologies enable more power to travel over

existing networks and reduce power losses

§The next step is being able to tailor responses to these

pressures across our entire portfolio

Drivers creating these opportunities

§Mature markets simply must be energy efficient to compete

in a global marketplace

§Emerging markets face energy demand

§concerns of climate change, energy efficiency is the most

immediate, inexpensive and practical way to reduce

environmental impact

how do we win

§more about learning to work together as an organization to

define, develop, communicate and execute customer

solutions for energy efficiency

§building a network of energy efficiency leadership with the

regions and divisions to share our local knowledge and

success stories.

§to supply innovative and flexible payback solutions as well

as technologies

§help customers understand the current and upcoming

regulatory landscape

§leverage these with unique solution sets that match the

breadth of our global footprint and the depth of our industry

expertise

Electric energy losses

§Most of the energy loss occurring on the distribution

system is the ohmic loss resulting from the electric current

flowing through conductors.

§Reactive power compensation devices are designed to

reduce or eliminate the unproductive component of the

current, reducing current magnitude and thus energy

losses.

§The voltage profile on the feeders, depending on the types

and mixture of loads in the system, can also affect the

current distribution, although indirectly and to a smaller

extent, thus affecting power loss.

Contribute to energy saving in power supply

§Using higher efficiency equipment, such as high efficiency

transformer, motor and VSD products.

§Condition maintenance management, guaranty equipment running at healthy status, improve performance.

§Operation optimization, guaranty unit running at high performance

load, to help improve convert rate and reduce emission.

§Load optimization, improve supply electricity quality and reduce

electricity loss.

Direct way for energy saving in power supply

§Using higher efficiency equipment, high

efficiency transformer and motor

§Using VSD tech, reduce throttle loss. VFD

§HV, MV, LV help system running at safety

and reliability

§Instruments, control system monitoring

process, and running in best situation by

advanced control strategy

High-efficiency Amorphous metal transformers

§

Energy savings and increased efficiency

§

No-load losses 40 -70% less than with e-steel

§

Efficiency increase by 0,5% to 1%,depending on rating

§

Lower Total Ownership Cost (TOC)

§

Continuous, guaranteed energy savings

from the moment of installation

§

Low loss transformers have generally

higher weight and have larger outside dimensions

§

With new transformers, the higher material cost will be compensated by reduced running costs from lower losses.Beyond a certain time, the lower losses will give a net financial saving from reduced energy costs

Ways to Reduce Po

Ways to Reduce Pk

Use better grade of core material

Use copper rather than aluminum

Use thinner core steel laminations

Use a conductor with a larger area

Use more turns in the coil Use fewer turns in the coil

Use a core with larger leg area

High-efficiency motors

§About two-thirds of electricity consumed

by industry is used to run electric motors

§Cost of buying a motor is ca. 3% of its

lifetime cost: energy consumption is ca.

94% (and rest is maintenance)

§An 11-kW motor (2% more efficient than

a competitor’s equivalent) can save 33.6

MWh, corresponding to 1.1 metric tons

of CO2, in one year of operation*

§A single pulp and paper factory can

have 2,000 motors running continuously

*operating 8,000 hours a year

High-efficiency motors

§Motor systems –a commission regulation regarding Eco-Design Directive (2005) requirements for electric motors has been adopted.The motors are already in compliance with the regulation, they are even before schedule.

ErP directive (Energy-related Products)

Timetable for the EU MEPS

IE class defined in the IEC/EN 60034-30 and IEC/TS 60034-31

Low voltage motors and EU MEPS

§Well prepared to meet the demands of the new efficiency classes

§Offers the largest range of low voltage motors available

§Has long advocated the need for efficiency in motors, and high

efficiency products (EFF1 in the former European classification

scheme) have formed the core of its portfolio for many years

§Has full range of IE2 and IE3 motors already today, available from

stock

§Has already today motors to meet IE4 super premium efficiency

requirements, output from 75 to 355 kW

Variable-speed drives

§

A drive can reduce energy consumption by as much as 50% for motors running pumps, fans or conveyors

§

Alternative is often to let motor run at full speed and “throttle” output (which is like controlling a car’s speed by braking while other foot is still on accelerator)§Less than 10% of motors worldwide are equipped with a variable-speed drive §

Installed base of drives saved about 140 million tons of CO 2emissions in 2008

tool for the design and testing of power

system developed.

§The NEPLAN Optimal Power Flow

module is extremely powerful for

power system design, planning and

operation. It solves power system load

flow, optimize system operating

conditions and automatically adjust

control variable settings.

§The optimized system will reduce the

installation and/or operating cost,

improve system overall performance

(e.g. minimize system real power and

reactive power losses) and increases

its reliability and security.

Reduce power loss by filtering harmonics

§The presence of harmonics in a power

system can give rise to a variety of

problems including equipment

overheating due to power losses,

reduced power factors, deteriorating

performance of electrical equipment and

other types of serve damage.

§The NEPLAN Harmonics Analysis

module provides the best tool to

accurately model various power system

components and devices to include their

frequency dependency, nonlinearity and

other characteristics under the presence

of harmonic sources.
