“Climate Protection in Kosovo through Energy Efficient

Water and Wastewater

Services”

- The EnMS an Open Platform and Methodology for Monitoring,

Analysing, Recommending Solutions and interventions for the Water

Utilities

- The Analyses and Recommendation at three Operational Water Units in

the RWUs/WOUs in the Republic of Kosovo

Water for Humans Sector

Climate Protection in Kosovo through Energy Efficient Water and Wastewater Services14.11.2016

Technically Analyzing the Energy of the Water using the methods of:

- Energy Efficiency

- Energy Optimization

- Energy Audit

- GHG

- Cost Benefit Analyzes

Concepts and the benefits

Way the water energy must be analyze using 5 concepts those

primarily are related with direct operation ?

What is the content of each concept operation ?

What is new in the EnMS proposed ?

What is/means predominantly “Energy”

in the

Water Systems

14.11.2016

Energy refers to the Basic Electric Energy

Unit equal to one kilowatt of power supplied

from an electric circuit for one hour.

Measured in kilowatt-hours (kWh).

Climate Protection in Kosovo through Energy Efficient Water and Wastewater Services14.11.2016

Efficiency of the Energy in the water sector is the ideal part of energy

the water is “receiving and losing” by moving from the source to the

reservoirs using the energy of the pumps for pushing it.

This means simply the analyze of the used energy in a part of the system

Pumps – Transmission main – Reservoirs

There are three key sub strategies that are easily implementable and can

be consistently applied using automation.

1- Operating individual pump or combinations of pumps as efficiently as possible

2- Shifting pumping to periods of lower cost

3- Avoiding or minimizing electric utility demand charges

To fully understand the potential benefits and energy savings of the strategies 2 & 3 it is necessary to have an

understanding of electric utility rate schedules and billing.

Seite 5

Implemented by

Energy Optimization

14.11.2016

- Optimizing Water Energy means to save water and save the Potential

Energy that the water has when reaching the water reservoirs.

Electrical Energy is changed in Mechanical Energy by producing Kinetic

Energy that is changed in Potential Energy.

This means the Electrical Energy is transformed several times and the

ENERGY is transferred to the water

- Simply the Energy Optimization concept of the water is related with the

hydraulic systems, Water Reservoirs - End Users and this concept

includes different “standard programs” into the operation of the

water services.


Seite 6

Implemented by

Energy Audit

14.11.2016

- It is a continuous process that must be introduced at the WUs,

deals with frequent controls and continuous monitoring of

devices by insuring optimal operational technical parameters,

maximum efficiency and minimum operational costs of

machineries.

- The Energy Audit as well deals with administrative and

managerial processes related energy usage and potentials for

saving.

Energy Saving & GHG reduction, indirect benefits

14.11.2016

- The Kosovo Energy Efficiency Action Plan (KEEAP) for 2010-2018 targets to reduce the

total energy consumption by 9%,

- Or a reduction of CO2 emissions by 91.89 ktoe. (Kilo Ton Oil Equivalent)

Actually the production of 1 kWh Electrical Energy the emission is 1.295 Kg CO2equivalent

- This will contribute to reduce the PM2.5- (an indicator that shows the air pollution with dangerous impact in the population health)

- Kosovo is on the top of top 10 countries in Europe who are operating Coal Power Plants for

producing Electrical Energy.

- The PM2.5 emission is a cancerogen element in air. The value of PM2.5 is 4.851 from

Kosovo 1 and comparing with Macedonia the second in ranking as polluter with PM2.5

with value 2.682, Kosovo is producing almost double.

- The EU is on track to reduce GHG emissions by 20 % compared to 1990 by 2020

- In this study the calculation of the CO2 e are made possible using ECAM software.

- 10 Estern European Countris, by producing Electrical Energy with Coal, are impacting

according to the calcullation the Western Europian caountries with 8.5 Billion Euros /year in

the health sector.

EnMs in daily practice

14.11.2016

In near future, systematic practice in the Water Utilities must be an

atomized EnMS model in form of utilizing:

- A skeletonized hydraulic model,

- A direct/ real-time SCADA connection

- A data/variables, PIs and KPI system as well the financial comparative/

virtual benefit and

- Advanced algorithms to schedule automatic, system-wide operation of

pumps, pipes, reservoirs and valves with the goal of

1- Meeting system demand, and

2- Minimizing total cost without rupturing system constraints.

Pumps with low efficiency in water supply systems

- A detailed technical cross chek using components of EnMS on sites,

pumpos with low efficiency are evident in water supply systems.

Water distribution systems with very high water losses and low

efficiency

- The Total Losses are very high.

- It is evident that the highest % of losses are technical losses at the

network distribution due to: (Next Slide)

Conclusions of the Presentation

Präsentationstitel hier eintragen14.11.2016

- The EnMS is a valid key platofrm for analyzing in all aspects the Water for

Humans Systems.

- The EnMS by being a open Platform accepts other concepts into it

- It is a must to introduce that in the daily operations and train the staff of

the Water Utilities in order to understand the importance and specializing

teams in each program and module.

- It is imperative demand creation of qualified actions chain in the daily

operations based on the EU standards.

- The management must base the analyzes of the operation and progress

on the EnMS in order to reach the objectives set up in the Business Plans

and improve the owerall water services.

- SHUKALB & SHUKOS are the bodies with capacities for training and

qualifying staff who will be ready for fulfilling the tasks at the WUs

- SHUKALB & SHUKOS must be in position for WUs CERTIFICATION
