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

ventilation can be reduced by up to 20%
Design smartly to reduce capital expenditures and operating costs
§NEPLAN is a comprehensive analysis
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.
