How Measurement and Verification Activities Supports Energy Management: Case Studies Geneviève Gauthier, National Director - Consulting Energy Summit 2018, Vaughan, Ontario May 30, 2018 1
AGENDA Today’s Challenge: M&V at a Glance Demonstrating that only data and humans Case Studies can maximize the benefits of energy management Questions practices. 2
M&V AT A GLANCE 3
WHAT IS M&V? Monitoring Monitoring: › Observe or track progress is not over a certain period. M&V Measurement and Verification: › Process of quantifying through measurements energy and cost savings and verifying that expected performance is met. 4
M&V AND ENERGY MANAGEMENT 5
CASE STUDY COMBINING THE EXPERTISE OF M&V EXPERTS WITH OPERATIONAL STAFF 6
INITIAL SITUATION › Steam is produced by fuel oil and biomass › Project: - Implement an Energy Management System (ISO 50001) - Save $750,000 per year › Carried a pilot project (workshop) to evaluate the potential of implementing an EMS: focus on biomass boiler Fuel Oil Consumption Annual Daily Total production facility 5,000,000 litres 13,700 litres Biomass boiler 500,000 litres 1,370 litres 7
KPIs - BIOMASS STEAM BOILER Fuel Oil Consumption Annual Daily Including scheduled maintenance shutdown 500,000 litres 1,370 litres Excluding scheduled maintenance shutdown 219,000 litres 600 litres Wood chips Oil Steam KPI = 1,370 litres / day KPI = 600 litres / day 8
WORKSHOP WITH STAFF February 28th Daily Consumption = 542 litres Wood chips Oil Steam KPI = 600 litres / day 24 Hours 9
WORKSHOP RESULTS › Reduce the cleaning time › Expected savings of $52,000 per year › Investment (pilot workshop): $15,000 › Payback is less than 4 months Fuel Oil Consumption Annual Daily Days in operation only 219,000 litres 600 litres Optimal operation 100,500 litres 275 litres Savings Potential 118,500 litres 325 litres 10
CASE STUDY IDENTIFY O&M OPPORTUNITIES WITH SIMPLE M&V TECHNIQUES 11
INITIAL SITUATION O&M measures, resulting from the M&V Expert deployment of an energy management contract, has led to substantial energy savings. Engineers Hired to: The program has to be - Estimate what could sustained be the expected energy cost increase if the CEO Why pay to maintain energy (and not decrease) the management program stops energy cost ? 12
INITIAL ANALYSIS BY THE CEO 10 000 8 000 x 1000 lb steam 6 000 4 000 2014 2015 2 000 - April May June July August September October November December January February Mars 13
M&V EXPERT - ENERGY MODEL › Energy consumption was modelled for the last year of the energy management initiative › 95% confidence interval was desired. › During a 5-month period, only one month was statistically significantly higher than the base year 14
CUSUM – SEE THE LIGHT! › Disruptive event in April. › In 4 months, 2,750,000 lbs of steam has been wasted = $55,000. 15
CONCLUSION › M&V does not have to be expensive or rely on high-tech measuring equipment and software › Simple techniques can sometimes lead to surprising results. M&V experts can shed lights on energy performance, even without fully understanding the process 16
