| The benefits of Intelligent Electricity Management include: |
|
| 1. Lower electricity use |
|
| 2. Reduced costs |
|
| 3. Reduced carbon emissions |
|
| 4. Extended operating life of equipment |
|
| 5. More efficient operation |
|
| 6. Reduced maintenance |
|
| 7. Lower capacity charges |
|
| 8. Increased energy security |
|
|
|
|
|
| What problems can IEM address? |
|
| 1. Poor power quality |
|
| (over voltage, poor power factor, harmonics, some transients, etc) |
|
| 2. Bill overpayment |
|
| (through incorrect estimation, poor metering arrangements and insufficient resources to analyse and validate bills) |
|
| 3. Lack of knowledge of onsite energy use |
|
| 4. Poor energy procurement |
|
| (through insufficient knowledge of onsite energy use) |
|
| 5. Poor energy practice and problems with onsite energy use |
|
| (through inability to benchmark and identify non-standard energy use via exception analysis and reporting) |
|
| 6. Site energy security |
|
| 7. Carbon emissions |
|
| 8. Lack of capacity |

|
|
| A typical IEM work programme |
|
| Phase 1: Initial measurement and analysis |
|
| Examination of historical data and measurement of current energy use |
|
| Phase 2: Addressing basic problems |
|
| Improving power quality (controlling incoming voltage, correcting power factor and filtering harmonics); where cost effective replace and upgrade energy intensive equipment |
|
| Phase 3: Installing temporary metering |
|
| Use a full energy audit to develop a detailed picture of on-site energy use over time |
|
| Phase 4: Automate and control |
|
| Where appropriate, install control systems (building management, motor control, lighting control) |
|
| Phase 5: Develop own generation capacity |
|
| Where cost effective, generate electricity and heat |
|
| Phase 6: Install permanent smart metering |
|
| Monitor, analyse and improve energy use over time using detailed analytics, control systems and energy management software |
