2. Onga M&V activities for 12L – General approach

• General approach– Cut once, measure twice, and compare

• Measurement– Option A: Retrofit isolation (key parameter measurement)

– Option B: Retrofit isolation (all parameter measurement)

– Option C: Whole facility

– Option D: Calibrated Simulation

• Verification– Operational verification: confirm the ECM functionality

– Savings verification: confirm whether expected savings achieved

3. Case study – Background (1)


Items Details

Sectors Industrial plant

Technology VSD application on fan systems

Quantity 3 fans: 2 operational and 1 backup

Targeted savings 7 539 MWh

Expected tax rebate R 7 162 050

Funding scheme Performance contracting (ESCo & Client)

Table 1. Project background

Challenges: • Data availability for baseline modelling• Data driven model: energy - production• First principle model:

• Installation type• Density at fan inlet• Desired airflow• Pressure required to move the set airflow rate

Table 2. Project milestones

FAQs: • Project registration: who is responsible for this?• Average project life cycle – registration to certificate?

Is it possible to shorten the process?

3. Case study – Scoping site visit


Figure 1. Fan to upgrade Figure 2. Existing metering system for Fan#2

Site visit: 04/02/2015

• FAQs:• Accessibility • Safety – SANAS requirements

3. Case study – M&V plan


• Project boundary– Furnace & the fan system

• M&V Option– Retrofit isolation: key parameter measurement

• Uncertainties– No sampling uncertainty since all fans are measured

– Handle measurement uncertainty

– Minimize modelling uncertainty

• Challenges– Selectin of the optimal M&V option

– M&V cost vs. uncertainty handling

3. Case study – Metering plan


Table 3. Metering configuration for baseline

Table 4. Metering configuration for PA

3. Case study – Calibration certificate


FAQs:

• Applicability of historical baseline data?• Who provide the calibration service?• Cost of calibration?• When to calibrate?• Time required?• Validity period of calibration?• Does the calibrate happen in lab or in-situ?• Does all type of meters need calibration?

3. Case study – Data for baseline

• Collected data for baseline:– Fan energy usage: 01/10/2014 – 31/01/2015

– Fan operation schedule: 01/02/2014 – 31/01/2015 (12 months)

– Plant production data: 01/10/2014 – 31/01/2015

• Baseline period– Immediate 12 months before project implementation

– 01/02/2014 – 31/01/2015 (12 months)

• Calculation of baseline– Baseline energy profile: monthly energy usage in kWh

• FAQs– Review & revision process
