The Purpose of AMR







Eliminate manual meter read
Better quality of data
Help to understand energy and water usage profile
Avoid energy and water wastage early
Making it easier for legislative compliance
Helps to justify energy efficiency and water savings
projects
Assists in bill validation and re-charges
Typical Meter Reading Installation
Manual meter reading system


Monthly or weekly meter reads
using clip board or handheld
devices
Manually enter the readings into
the energy management
software.
Automated meter reading system



Half-Hourly meter reads via a
suitable method
Meter reads transferred
automatically into a database
The energy management
software uses this database for
further analysis

The University of Leicester

The University has an extensive estate in the City of
Leicester, Oadby and Glenfield comprising of:
5
main sites
 291 buildings occupying an area of 290,455 m2
 48 hectares of grounds


Number of employees – 3,803 (2010-11)
Number of registered students – 22,784 (2010-11)
What do you know about your meters?




Gas - Do you know your MAM (Meter Asset Manager)?
 National Grid / Energy Asset / Smart Metering System /
Exoteric / Off Stream/ etc
Electricity - Do you know your MOP (Meter Operator)?
 Siemens / EDF / EON / British Gas / etc
Of course, you need to know your suppliers
Meter location is important (plant room/boiler house/ pavement/
under kitchen sink/cleaner cupboard/etc)
AMR Tender



UoL has been through
2 AMR tenders
Tender 1 (2007) –
Non-Residential
Buildings
Tender 2 (2011) –
Residential Buildings

Selection criteria
 Cost
 Software
user-friendliness
 Data collection method
 Installation experience
 Ongoing maintenance for
hardware and software
 Staffing levels

The Use of AMR - Projects
-
- Business case energy efficiency projects
-
- To prove energy saving projects
Charles Wilson Building Voltage Optimisation Project
Before :
Energy consumption – 1,415,098 kWh
Energy cost - £112K
After :
Total project cost - £51K
Savings predicted – 11%
Savings per year projected - £11,846
Payback – 4.4 years
CO2 savings – 83.6 Tonnes pa
The Use of AMR – Switch Off
-
-
- To prove behavioural change projects
- Example: Student Switch Off Project during Feb 2012
at Percy Gee (Students Union Building)
 26kwh saved over the switch
off period.
 5% saving compared to
previous Thursday (2/2/12).
The Use of AMR – User Access
- AMR access
for
environmental
coordinators
The Use of AMR – Billing & Re-charges
- Set-up
energy
contractors
within AMR
software for
re-charge
purposes
Tips to Maintain AMR System





Dedicated personnel resource depending on size of
the system
Set alarms and monitor alarms on a daily basis
It’s good practice to take 1 or 2 manual meter
reads per year to reconcile the automated reads
Site tree structure
AMR providers to provide familiar reports
Finally …. Things to bear in mind






Make sure you have valid business case for the
preferred AMR system
Ensure you choose an appropriate data collecting
system that works for your institution
Speak to your utility suppliers, MOP and MAM
Choose a user-friendly software
Small contingency pot for unknown meters
Ensure you have a maintenance contract for
hardware and software, which suits your institution
