Pre-Installation Evaluation of Industrial Projects

Objectives
Primary Discuss methods, advantages, and
disadvantages of very early impact evaluator involvement in a large industrial process program
Also share Procedure Case studies of pre-retrofit activity
What is Pre-Installation Impact Evaluation?
Core activity: Project engineering review before savings claims are finalized Pre-installation savings calculation review Baseline characterization Pre-installation metering
Also/possibly: Early free ridership assessment Early post-retrofit review & metering Training PA and their technical advisors
Why Do It?
Benefits for evaluators Evaluator inspection in pre-retrofit
state Input regarding administrator M&V
plan• Opportunity for independent direct M&V
Baseline perspective at time of decision-making
Evaluator-administrator convergence/training
Bottom Line: Increased engineering rigor less variability, greater confidence
in results
Why Do It?
Benefits for program administrators Evaluator-administrator convergence/training Adjustment to savings estimates prior to
incentive calculation Increased depth of engagement with
facilitators Less disturbance to customers
Bottom line: Better realization rates Fewer surprises
Why Not Do It?
Added cost for evaluators and administrators Planning $2k to $10k per project evaluator cost; less but some
admin• Modest ex post savings later
Sunk evaluation costs on projects that don’t matriculate Monthly meetings
Risks added calendar time to processing Short notice rush analysis required Baseline can require research. Admin waits?
Added bureaucracy before closing the deal
How It Works
ID candidate projects
Evaluator review
Evaluator & administrator meet on analysis, baseline, and proposed pre-
installation metering.Pre-install site visit. Possible
metering
Existing facility
New facility
Evaluation review memo
Evaluator & administrator
meet
Post-install site visit
Tracking
How It Works – Screening
Establish screening criteria in advance Example: All over 5 GWh/yr or 10,000 MMBtu/yr All over intermediate size range and
process, complex baseline, capacity expansion, controls, etc
Sample others in intermediate range
Evaluator or administrator can ID projects
How It Works - Variations
Are early evaluator findings advisory or definitive to program?
Is free ridership assessed? Is result shared? Is it considered when setting incentives?
Formality of communication Who does the M&V?
Case Studies
Paper includes four case studiesGood Working together on M&V approach Evaluator influencing administrator on
baseline characterization, and vice versa
Bad Lost sunk costs No consensus on baseline Timing challenges
Summary Pre-Installation Impact Evaluation
Advantages:
Better evaluation engineering & statistical quality
Better realization rates
Fewer bad surprises at end of evaluation
Costs:
More labor
Calendar concerns
