Planning for Energy Cost Reduction Projects

Get into the W eeds

• Understand current consumption

– Energy consumption by site – Focus on major end uses of energy – Utilize sub-metered data – Look at demand profiles and time of use

• Look at your energy expense

– Allocate expense into high level buckets

• Consumption
• Demand
• Capacity

5

Evolving Opportunities

• Fruit that has fallen

– Implement easy to make operational changes that can be implemented through existing control devices

• Setpoints
• Setbacks
• Low hanging fruit

– Projects with a relatively low cost, quick payback, that are easy to implement

• Stretch projects

– Look at holistic savings opportunities by considering non-energy impacts such as maintenance and asset availability – Put multi-year strategy in place

6

Demand Response and Peak Load Shaving

Maxim izing Existing Program s

• Prior to 2016, Giant Eagle participated in

traditional demand response programs by lowering electricity demand in supermarkets

• In 2016, Giant Eagle began to monitor

instantaneous load on PJM and engaged demand response load shed during peak times to lower our capacity tags for the following year

• Increased events required:

– Additional resources devoted to program – Increased communication to supermarkets and internally at corporate – Measurement and verification of performance

Typical Loads Event Loads

7

Retro-commissioning

Optim izing Efficiency of Existing System s

• Validate system setpoints are in line with

internal standards

• Identify and correct where equipment is

not operating properly – Broken lighting contactors – Bypassed VFDs – Inefficient compressor

• Measured and verified savings of 10%

energy reduction on major building systems

• Filled in information gaps

– Large HVAC units without VFDs

8

LED Lighting

Significant Reduction Over Tim e

• Implemented Over Five Years

– Started with backrooms and stock areas – Convivence Stores – Salesfloor, Cases and Exterior

• Energy Efficiency Win

– Reduce a major end use of energy by more than 40% – Implemented along with dimming and

• ther controls
• Auxiliary Benefits

– Lowered maintenance costs – Fewer outages – Improve aesthetic

9

Current Projects

Better I nsight and Control

• Centralized system information platform

– Pulling in major system settings and data into holistic platform – Creating insight across entire portfolio in real-time

• Advanced HVAC control

– Reactive, dynamic controls – More sophisticated control strategy

2018 2017 2018 DC2 shuttered for extended period and had compressors salvaged and taken to DC1

DC2 Now Operating with Old DC1 Compressors

2015 By end of the year all 3 compressors were swapped out

One compressor fails and we install one with a VFD

1) End of 2018/Ongoing Reduce or eliminate “Chimney Effect” on HO VAV and HW Radiant Loop system along with implementing 45 degree hot water resets 2) Spring 2019/Ongoing ‐ Remove user locked setpoints from VAV. Dead band decreased. Setpoints now broadcasted from AHU now. This also eliminated hunting and conflict between VAVs in open areas. Status: HO (Phase 1) Done DC’s Started, est. 80% done 3) May 2019 ‐ Chilled water set points raised from 42 deg to 44 deg at both DC’s

4) Spring 2019 ‐ Chilled water set point raised from 44deg to 50deg for building with data center/IT at the HO. 5) June 2019 – Match staged cooling of chillers to building demand based on schedule to eliminate whole plant running 6) Dec 2019 – Change boilers to Lead / Lag configuration. Both ran constantly previously. 7) Dec 2019 – Aggressive Scheduling of DC2 AHUs

Operational Projects Best Practices

Culture of Operational Savings

• Find Statistically Significant Energy

Drivers

• Provide validated measured savings

to finance

• Catch all for overlapping savings on

larger meters

• Can be done in Excel but AEP

Program provides access to better statistical tools

Modeling/Measurement (AEP CEI)

CUSUM Chart

25

• Too easy to get lost in the day to day
• There will always be fires to put out
• Stay on target for critical dates like peak periods

and holidays

• You won’t catch every operational savings
• Identify cascading and interconnected savings
• Go together, you will need buy in for some projects

Team Meetings/Group Emails

• Maximize areas of expertise and highlight those

doing the work as high as you can

• There are legitimate reasons projects don’t work
• Energy has a legitimate use
• Be able to pass on things to the next person

Cross Functional Collaboration
