Sustainable Energy Cohort Washington Wastewater and Water Dorothy Atwood Olympia, Washington October 11, 2012

Homework Debrief Who is on your energy team? How often to you meet? Is it a regular meeting? What is the status of your Energy Policy? Who knows about it? What did the Spider assessment diagram reveal about your energy management efforts? How do you track energy use? What are your energy Key Performance Indicators? Which of these are you tracking: kWh/MGD, KWh/1,000 # BOD removed? What is your baseline energy period? Any challenges in establishing it Which O&M projects were most attractive to you? Have you started one?

Assessment Tool - Radial (Spider) Diagram 10 energy management system topics – E.g. Energy goals, training, audits Three questions per topic – Answers gradational from 1 to 5 Transfers results to Radial Graph Perform assessment at beginning and end of program

Creating an Effective Opportunities Register

PDCA – What does it mean? Manage Projects Plan Projects Do Projects Check Project Progress Conduct strategic review of project Manage Process Create planning process (SMS core team, etc.) Develop/Maintain support programs (e.g. training, communication, documentation) Check system (data collection/metrics, audits) Strategic review of system

Suggestio ns Contractor & Vendor Ideas Energy Audits Incentive s Use Less Energy Every Year Decrease Energy by 25% in 10 yrs Zero Net Energy in 5 yrs Energy Policy We Care About Energy Suggestions EnMS Audits Contractor & Vendor Ideas Energy Audits Incentive s EnMS Audits

Energy Opportunity Register Keep it simple Let it evolve. (Don’t do it just once!!) Review in monthly or quarterly energy team meetings Update annually – let it help inform energy improvement plan for upcoming year Link to Capital Improvement Project (CIP) process

Tour Option 1: Secondary Treatment Process (including aeration and pumping) Tour Option 2: Solids Processing Tour Option 3: Disinfection and Effluent Pumping (including U/V) Plant O&M Focus Tours

Post Tour Focus Questions 1. What are some suggestions of ways to address the energy challenges brought up in your tour? 2. What are other possible O&M measures LOTT could take to improve their energy savings and operations efficiency? 3. What are some methods/measures introduced in the tour that you hadn’t thought about? What are some methods you learned that you might consider for your operations?

Master Calendar Highlights REGULAR reoccurring events Identifies opportunities for integrating into existing regular functions Reminds Energy team of key items to review and update

Crafting an Effective Employee Engagement Program

Employee Engagement Brainstorm with a partner (not from your facility) 3 to 5 energy topics for awareness/engagement 3 to 5 engagement methods or techniques that worded Horror story of training initiative gone wrong

Benefits of a System Moves from single ad hoc energy projects to an integrated approach Provides a framework for moving towards energy independence Is proactive rather than reactive Involves everyone with energy improvements Uncovers cost saving ideas Transfers learning from project to project
