Saving energy makes good business sense
WFGE Gliwice
Many companies think of energy as a fixed overhead but saving
energy is actually one of the easiest ways to reduce costs and
improve your reputation.
•
Save money
- Simply by switching machines off after use, or turning the
heating down in warm weather, you can make real savings on your energy bill. And just
reducing it by 20% could add the same amount to your profits as a 5% increase in
sales.
•
Enhance your reputation - Increasing numbers of consumers and
business customers will now only buy from, or invest in, companies with
environmentally friendly policies and production methods. By demonstrating a
commitment to reducing carbon emissions, you will increase your appeal in the market
and attract a wider customer base.
•
Stay ahead of government regulation - With climate change so high
on the political agenda, we are likely to see more initiatives like the Climate Change
Levy and the Emissions Trading Scheme, as well as tighter building regulations. Being
prepared for these changes now will save you time and money when they are
introduced. Plus, if you start saving energy straight away, you will immediately reduce
the levy on your energy bill.

What should be done to prepare energy contract :
 Grid Contract
Separate electricity & grid contract
 Prepare electrical meters according to
network distributor requirements
 Define maximum Capacity / annual volume :
……. MW ; ……...MWh
 Load Management Forecast available:
yes, daily hourly forecast for next day
 Prepare load profile for supply period available
yes
 Guarantee reliable commodity supply
 Obtain most favorable pricing structure
 Achieve acceptance of payment terms while limiting supplier credit requirements
 No credit/bank guarantee from company
 Reduce Take or Pay conditions as much as possible
 Confirm financial viability of selected supplier

Energy saving in pumps systems
WFGE Gliwice
 Reduction Strategy
 Adjustment of capacity to minimum
process necessity
 Replace of flow regulations using
throttling valves with more efficient
regulations with frequency
converters
 Application of energy efficiency
electrical drives
 Replace old oversized pumps with
modern adjusted to necessary
capacity

 Installation of frequency converters for cooling water pumps in 3 circuits: Primary,
Chillers, Body Shop & common master controller for all system improves efficiency of
heat transfer system
 Total saving - E saving > 2 000 MWh = 100 000 Eu - without investment cost (70 000 Eu)
 PBT < 1 year

Lighting Business Case
WFGE Gliwice
Reduction Strategy
 How it Works - shorter time delay
period for lamp warm-up to ensure
stable operation of the lights,
before switching to a lower energy
saving voltage.
•Implementation of LEC (Light Energy
Controller) in fluorescent and metal halogen
lighting circuits benefits:
 Reduction of energy consumption 18 – 23 %
 Extension of fluorescent lamps live – twice
 Reduction of maintenance cost

Modification of HVAC control system
WFGE Gliwice
Modification of HVAC re circulation system :
– Re circulation flap are operated to ensure:
• Set up room temperature – 18 C in production and 20 C in office area
• Not to freeze the HVAC system
• Max fresh supply air
– Heating system work only when room temperature is lower then allowed level
– Recovery of warm air heat energy under roof

D - Optimize your power demand
WFGE Gliwice
• Sign grid contract with possibility to change
ordered power
• Control your power demand ( 15 min. )
• Optimize power demand if possible
• Change ordered power when required

PFC
cos fi
- Check your power factor correction system
WFGE Gliwice
• The power factor of an AC electric power system is defined as
the ratio of the real power flowing to the load to the apparent
power , and is a number between 0 and 1
• If the power ratio PFC > 0,4 , you pay penalty
• If supplying system is overcompensated , you pay penalty
• Check your bill
• If you pay for PF - check your reactive power corrective
system

What is worth remembering
WFGE Gliwice
• Poland is not an island – there are international energy players,
market convergence, energy price starts to follow-up oil price,
• Further increase of correlation between Polish and European
energy price changes
• Low energy price is a history – IPPC regulation, CO2 emission
trading, color energy duties, old energy infrastructure, necessity to
build new nuclear/”0” CO2 emission power station, refurbishment
of distribution network,
• Active players can find interesting product
• Energy management lead to energy consumption decrease
• URE –authority control household energy tariff (40% of energy
market) and distribution tariff

How strong are relations between energy sector & industry
WFGE Gliwice
Energy producer , traders,
distributors, ecological
organization has a strong
political lobby
The industry consumers
organization lobby should
become stronger
