AUSGRID DEMAND / CAPACITY CHARGES
Recap
- use >= 40 MWh pa
- based on highest reading over a standard half-hour interval during the previous 12 months between 2pm and 8pm
- n working weekdays
- unit of measurement – kW or kVA – depends on annual consumption
- 1 July 2018 to 30 June 2019 rates below
* including GST
Annual Consumption Tariff Cost * 40-160 MWh per annum EA302 LV 40-160 MWh 40.1023 c/kW/day 160-750 MWh per annum EA305 LV 160-750 MWh 40.1023 c/kVA/day > 750 MWh per annum EA310 LV >750 MWh 40.1023 c/kVA/day
INTERVAL DATA
Recap
- power demand at
various times throughout the day
- 15 or 30 minute
intervals
- interval / smart meters
- measure of how effectively you turn the
electricity supplied by your electricity distributor into actual productive power (i.e. light, heat, motive power)
- mandatory to maintain a power factor of at
least 0.9
POWER FACTOR
Recap
THE BENEFITS OF REGULAR MONITORING
Maintain Your NABERS Energy Rating
Daily consumption Usage patterns – weekdays & weekends Time-of-use splits Maximum demand Power factor Know when things go wrong Recognise
- pportunities for
reducing costs

The Benefits of Regular Monitoring?
PEAK CAPACITY CHARGE BASED ON
- highest reading
- ver a standard half-hour interval
- during the previous 12 months
- between 2pm and 8pm on working
weekdays
LIMIT PEAK CAPACITY / DEMAND CHARGES

LIMIT PEAK CAPACITY / DEMAND CHARGES
The Benefits of Regular Monitoring?
Poorly timed HVAC testing cost the site an extra $5,200 p.a. in demand charges

ANTICIPATE EQUIPMENT FAILURES
The Benefits of Regular Monitoring?
Power factor fluctuations caused by a sick motor
SERVICE CONTRACTOR ACCOUNTABILITY
The Benefits of Regular Monitoring?
- not uncommon for contractors to create a
new problem
- examples in next section

WHAT CAN GO WRONG?
The Benefits of Regular Monitoring?
- car park ventilation
controlled by CO monitors
- technician testing fire
equipment left fan control switch on “manual”
- fans ran 24/7 for 2 weeks
until a resident noticed
- $100 extra per day
SERVICE CONTRACTORS CREATE NEW PROBLEMS
The Benefits of Regular Monitoring?
- sump pumps left running
continuously after quarterly service
- unlikely to be noticed
between quarterly services due to location
- would have cost approx
$2K between services
SERVICE CONTRACTORS CREATE NEW PROBLEMS

Power factor correction unit left switched off after service
SERVICE CONTRACTORS CREATE NEW PROBLEMS
The Benefits of Regular Monitoring?
Never found out & it went back to “normal” after 2 weeks!
EQUIPMENT FAILURE – CO SENSOR
The Benefits of Regular Monitoring?
Additional 24-hour load
- f ~ 4kW for
a year
EQUIPMENT FAILURE
The Benefits of Regular Monitoring?
VSDs on bathroom exhaust fans
- new load
between 11:00 pm and 6:30 am (outside working hours)
- timer on stand-
alone air- conditioner in building manager’s office
- would no have
been picked up
- therwise!

MONITORING TOOLS
Maintain Your NABERS Energy Rating
- limited information other
than something’s wrong!
- can’t identify when
problem occurred
- worse if quarterly
INVOICE COMPARISONS
Monitoring Tools
- reveals if equipment is operating out of normal hours
- allows you to investigate irregularities
- allows you to check maximum demand / peak capacity
- free access to RAW interval data for past 2 years through Ausgrid or retailer

- somewhat limited information
- frequency
- could narrow down to day of problem
- cannot generate different report

IMPORTANCE OF MAINTENANCE
Operational Changes
- Poorly / not maintained equipment
uses more energy
- dirt
- heating & cooling systems
- hot water systems
- air leaks
- poor calibration
- etc
- Maintenance extends equipment life
- Develop site specific
energy efficiency maintenance specifications
- Supervise & monitor
performance of maintenance contractors
- Penalties / incentives in
contracts – carrot or stick?
