What is this handout about?
Dearreader,
The machinery is the driving force behind
the economy of any country. As Ukraine is
no exclusion, the development of machin-
eryenterprisesisofsuperiorpriorityforthe
economicgrowthofournation.
However, do you know exactly how much
energy is needed to process 1 kg of metal
and other materials to manufacture
engineeringproducts?Howmuchmoneyis
spent on the energy needed to produce a
certain part? Are you aware which produc-
tion areas, relevant energy-saving poten-
tials are waiting to be discovered, and how
cost-reducing energy saving measures
with rapid returns can protect the environ-
mentandyourwallet?
This short outline provides insight into the
energyconsumption,energycosts,energy-
saving potential, specific energy-saving
measures and the greenhouse gas impact
ofmachine-buildingindustriesinUkraine.It
reports the results of a series of energy
audits, provided by the Deutsche
Gesellschaft für International Zusam-
menarbeit (GIZ) GmbH and demonstrates
the impact of GIZ projects currently being
implemented within the energy efficiency
andclimatesectorinUkraine.
Therefore, the content of this short report
willbeofinteresttoCEOs,companyowners,
managers and investors in the Ukrainian
machine-building industry. Relevant to all
stakeholders, this outline is not targeted at
energy efficiency experts only; hence, the
use of technical jargon has been
minimized, and complex technical issues

Economics is the principal driver for
industry and, subsequently, the largest
incentive for increasing energy efficiency is
to lower total operating costs. Fortunately,
there are numerous opportunities for
increasing efficiency in small- to
medium-sized companies. Studies have
shown that up to 35% of energy
consumption within the entire Ukrainian
industry could be reduced in the near term
throughcost-effectiveefficiencymeasures.
The Federal Ministry for Economic
Cooperation and Development of
Germany (BMZ) pledged its support for
the Ministry for Development of
Economy, Trade and Agriculture of
Ukraine (MDETA) and has since imple-

mented a range of measures to bolster
means for improving energy efficiency.
One of them is the project Advisory
Services for Energy Efficiency in
Companies that GIZ has been
implementing since 2017, on behalf of the
German Government.
The project provides direct technical
support to Ukrainian industries, which
includes conducting energy audits and
developing pilot projects, which are
specifically tailored to the needs of
local industries. The results of these
energy audits enable Ukrainian
industries to develop technically and
economically sound energy efficiency
investment measures.
SinceOctober2018,ateamofnationaland
international certified energy auditors has
assessed the level of energy efficiency of
65 industries according to ISO standard
50002, Part 2. This audit phase was
completed in July 2019, with a focus on
industrial sectors such as bakeries, dairy
production, and non-metallic building
materials. As a result, 20 companies were
selected to be audited for investment
gradeaccordingtoISO50002type3,which
was concluded in March 2020.
were audited according to

The current outline is a byproduct of
these activities, taking advantage of
assessing 18 industrial machinery
plants, and identifying their energy use
patterns to determine promising
energy-saving measures. The outline
reveals typical consumption profiles as
a first approximation, which contributes
to a better understanding of energy
efficiency in the Ukrainian industrial
sectors. In turn, this also provides
greater comparability amongst sectors.
Subsequently, this document has the
potential to stimulate and encourage
decision-makers to put energy
efficiency into practice.

What is an energy
audit according
ISO 50002?
What is an investment-grade audit?
Owners or managers of industrial parks
and factories are not always aware of
the possibilities for energy efficiency
improvements. Conducting an energy
audit is the first step to investigate the
opportunities for energy savings, priori-
tizing projects, tracking progress, and
making system adjustments after
investments.
ISO 50002 specifies the process require-
ments for carrying out a comprehen-
sive energy audit. It is applicable to all
types of establishments and organiza-
tions, and all forms of energy and
energy use. This standard also specifies
the principles of carrying out energy
audits, requirements for the common
processes during energy audits.
An investment-grade audit is the most
detailed energy audit. It analyzes the
financial aspects of energy savings and
the return on investment from potential
changes or upgrades. A building opera-
tor typically uses the investment-grade
audit as a budgeting tool when planning
facility upgrades.

Machineryisoneoftheleadingindustries:its
share in the Ukrainian industry structure is
about7.3%.Overthepasttenyears,itsshare
peaked in 2012, when it amounted to 10.32%,
and reached its low point in 2016 (6.1%)1
.
Ukrainehasenormousopportunitiesforthe
development of agricultural machinery and
the provision of food and processing
companies with modern equipment.
2011–2017 witnessed an increase in the
production of electrical equipment, motor
vehicles,electronicandopticalproducts.
At the same time, the dynamics in terms of
the main types of products indicate the
irregularity of contracts and instability of
production. The industry also encounters
challengesassociatedwiththedeterioration
offixedassets.
Challenging economic environment and its impact on
energy efficiency
The low level of energy efficiency of the
equipment and suboptimal use of produc-
tion capacities significantly reduce the
profitabilityofproduction.
As a result, the number of large and medi-
um-sized machine-building enterprises in
Ukraineisdeclining.
Thus,from2010to2018,thenumberoflarge
enterprisesdecreasedby52%(from52to25
companies), and medium-sized - by 20%
(from 921 to 757). Instead, the number of
small enterprises increased by 4.7% (from
5,765to5,941)1
.
Improvingthecompetitivenessinthisindus-
try requires the energy modernization of
Ukrainian enterprises: the introduction of
new technologies and the implementation
ofenergyefficiencymeasures.

Carbon dioxide (CO2
) is a colorless gas formed during the combustion of any
material containing carbon and important greenhouse gas.
Carbon dioxide equivalent CO2
eq is a measure used to compare the emis-
sions from various greenhouse gases based upon their global warming
potential.
For example, the global warming potential for methane over 100 years is 21.
This means that emissions of one metric ton of methane equivalent to emis-
sions of 21 metric tons of carbon dioxide.
What sources of energy are used and in which quantity?
The 18 assessed industries consumed
between 0.4 and 62.7 GWh of energy in
2018. The inclusion of both large
industries and smaller Ukrainian
machine-building plants in the audit-
ing process accounts for the striking
difference between the smallest and
largest value.
The enterprises can be split into two
groups by their energy consumption
levels, the one consuming from 0.4 to 9.6
GWh a year, and two enterprises that
were consuming 29.7 and 62.7 GWh/year
respectively. The annual average repre-
sented by the last bar to the right (see
Figure1onthenextpage)makes3.8GWh
and has been calculated without taking
into account the two enterprises with
considerable consumption levels.

The next pie chart reveals the share of
the main energy sources - electricity,
natural gas, wood, and coal in 2018.
Figure 2 shows that the machine-building
industry is highly dependent on electricity
(50.4 %) with natural gas trailing well
behind (19.9%). This is due to a consider-
able reduction of its consumption in the
productionprocesses,e.g.,forquenching,
melting, or drying of varnish and paint

Figure 3. Energy consumption in 2018
shares among production processes,
infrastructure, and losses
Energy losses occur throughout
the energy supply and distribution
system. Energy is lost in power
generation and steam systems,
both off-site at the utility and
on-site within the plant boundary,
due to equipment inefficiency and
mechanical and thermal limita-
tions. Energy is lost in distribution
and transmission systems carry-
ing energy to the plant and within
the plant boundaries. Losses also
occur in energy conversion sys-
tems (e.g. heat exchangers, pro-
cess heaters, pumps, motors)
where efficiencies are thermally
or mechanically limited by materi-
als of construction and equipment
design.
Figure 3 indicates how much energy is
consumed by a typical machine-build-
ing plant for production, heating and
hot water supply purposes.
As expected, 85.5% of the energy is
consumed by the production processes
with the heating and hot water supply
systems using about 8.2%, and the
remaining 6.3% are lost.

What are energy-efficiency measures and where
is the largest savings potential?
Energy Efficiency Measures (EEMs)
are energy-using appliance, equip-
ment, control system, or practice
whose implementation results in
reduced energy use while main-
taining a comparable or higher
level of service. EEMs decrease the
amount of energy needed to pro-
vide the same level of comfort or
utility (e.g. a heating or cooling
system that provides the same
comfort with less fuel or electricity;
a boiler of comparable size and
features that uses less gas).
To manage the diversity of potential EEMs, we classified them into the following subgroups of consumers:

approximately 1°C (likely between
0.8°C and 1.2°C) above pre-indus-
trial levels in 2017, increasing at
0.2°C (likely between 0.1°C and
0.3°C) per decade (high confi-
dence).1
Global warming has brought
about possibly irreversible
alterations to Earth's geologi-
cal, biological and ecological
systems. These changes have
led to the emergence of large-
scale environmental hazards
to human health, such as
extreme weather, ozone deple-
tion, increased danger of wild-
land fires, loss of biodiversity,
stresses to food-producing
systems, and the global spread
of infectious diseases. In addi-
tion, climate changes are
estimated to cause over
150,000 deaths annually.2

How can your industry contribute to mitigating climate change?
The implementation of energy
efficiency measures will strengthen
your competitiveness as it reduces
your operational costs. In the same
breath, it addresses another, all over-
laying and pressing challenge: Climate
change.
The rise in global average tem-
perature is attributed to an increase in
greenhouse gas emissions. There is a
link between global temperatures,
greenhouse gas concentrations –
especially CO2
– and its emission due
to the use of fossil energy sources in
industries.

25. In a typical machinery plant, the imple-
mentation of up to two energy-saving
measures, with each investment cost-
ing below 60,000 UAH would contribute
to 5.2 % of the energy savings. Up to
two measures with investment costing
from 60,000 UAH to 300,000 UAH each
would bring a potential saving of 6.5 %
while up to four measures with invest-
ment cost of more than 300,000 UAH
each could save 88.3 % of the energy
consumed.

28. Examples of EnPIs are energy
consumption per time, energy con-
sumption per unit of production, and
multi-variable models.
The values presented in Figure 13
should be understood as a rough
reference, not directly comparable due
to the different product range, product
mix, and production processes of each
industry. But they can serve as stimu-
lus for companies` managers to
develop their own specific set of EnPIs.
How much energy is used to process metal?
28
To address this question, we will
have to introduce a few terms that
might be new to you.
According to the ISO 50001 standard,
“energy performance is the measur-
able result related to energy efficien-
cy, energy use, and energy consump-
tion.” The energy management sys-
tem performance can be measured
using Key Performance Indicators
(EnPIs). “Energy performance indica-
tor is a quantitative value or measure
of energy performance, as defined by
theorganization.”Itisimportanttoset
appropriate EnPIs for monitoring and
measuring the energy performance
because they show how well the
system is functioning.

In 2018, the specific energy consumption of the four machine-building plants in kWh
per 1,000 UAH-worth products sold ranged from 37 to 337 kWh/1,000 UAH. For seven
other enterprises, the specific energy consumption indicator was identified in kWh
per 1 kg products sold and had the value range between 2.1 to 41.8. It was not possible
to determine energy efficiency indicators for the seven machine-building enterprises
in absence of a clear-cut structure of energy costs and production.

- The total annual energy consump-
tionofthe18assessedmachine-build-
ing plants in 2018 ranged from 0.4 to
62.7 GWh with the average value of 3.8
GWh.
- The machine-building
industry highly depends on
electricity as its energy
source, which makes for 50.4
% of the consumption with
natural gas trailing consider-
ablybehindwith19.9%.Wood
and coal account for 29.7 %.
- The respective electricity
consumers are: technological metal

(80.5 % of the energy costs) on
electricity, 1.41 million UAH (9.5 %)
on natural gas, 1.18 million UAH (8
%) on wood and 0.3 million UAH (2
% energy costs) on coal .
- Relevant consumer groups for

heat distribution (458), lighting (181),
electricity generation and supply
(123), production processes (94) and
compressed air system (93). The
electric drives occupy the last place
(48).
