Business Case for Energy Management

Retail Example: €100,000 p/a

•  If you make 5% energy savings (~€5,000), where does that 5% / €5,000 go?

•  How many retail items would you need to sell to make €5,000 in profit? - Could be worth an extra week of trade?

Are you paying too much for Energy …..?

Energy Supply Energy Usage

Pay less per

unit of energy

Reduce energy

consumed

AIM

To achieve organisation objectives at minimum energy

cost

Understanding your Energy Bills


•  Power: kilowatt (kW)

•  Energy: kilowatt hour (kWh)

•  1 kilowatt = 1,000 watts

1 L 2.68 kg

10.161 kWh =


•  A 100W light bulb = 100W

•  Ten 100W light bulbs = 1000W or 1kW

•  kW multiplied by hours = Units of energy (kWh)

•  1kW x 8670hrs = 8670kWh p/a

•  @ 16c/kWh = €1400 p/a


•  Simple

•  Cheap

•  Awareness

Historical Electricity Tariffs

•  General Purpose

•  General Purpose NightSaver

•  Low Voltage Maximum Demand

•  Medium Voltage Maximum Demand

•  High Voltage Maximum Demand

If night use <10%

If night use >10%

If MIC > 50kVA

If MIC > 450kVA

Alternative Electricity Tariffs

•  Bundled

•  Unbundled

•  STOD

•  Gas Tracker

•  Variable

•  Fixed

•  Managed

•  Etc.

•  Excess Capacity Charge

Excess MIC Penalties

•  MIC -

– HEAVILY PENALISED for the excess – ONCE for 15 minutes in a month. – Measured in kVA

Example of Excess MIC Penalties

•  This is an EXTREME example !!!

Excess MIC ? What should you do ?

•  If possible reduce peak demand

•  If not - seek an Increase in MIC from ESB Networks –  Possible capital cost –  Payback varies –  Increase in capacity charge –  TALK to ESB Networks, NOT your supplier !

What if my MIC is too High ?

•  MICs too high will attract additional ‘ Fixed ‘ Charges !

•  You could be paying for capacity you will never use ..

•  Capacity Charge & PSO levy is based on your MIC level

Excess Wattless /Low Power Factor

•  Have you Low Power Factor Surcharge on your Bill ?

What should you do ?

•  What should you do to eliminate these penalties ?

•  Ask your Electrician 3 Questions: –  Do we have a Power Factor Correction installed? –  If we have one, is it working? –  If it is working , is it big enough?

•  Ask yourself one final question : Is it on a regular Checklist ?
