ASD Goal: 20% Reduction by 2020
• District spends ~$15M/yr on Natural Gas ($5M) &
Electricity ($10M)
– 20% Reduction = $3M/yr savings
– $3M a year x 15 year (term of loan) = $45M
– $45M invested over 3 years
– Potential savings based on:
◦ High efficiency condensing boilers (20%)
◦ LED lighting (25%)
◦ Retro-Commissioning (10%)
◦ Combined Heat & Power
◦ Solar

Pitfalls• Pursuit of Alternative Energy Financing
– Lengthy process vs initial project ROI development
• ~60-90 days develop/present Business Case
• ~60 days for School Board & Assembly approval
– Explored financing through RFP/ESCO/AHFC only to find out Municipal Charter requires voter approval
– MOA Master Lease only requires Assembly approval
• Interest rate & terms impact ROI
• Nationally recognized ESCO required
– Understanding the loan

Pitfalls
• Learning Curve on Co-Op AKDOT&PF ESCO
– Lengthy process to understand/justify ESCO and seek administration/board approval
– Fist hybrid RFP unsuccessful; needed to revise RFP and re-solicit, but contract expired

Pitfalls• Pursuit of Alternative Energy Opportunities
– Lengthy process to understand playing field
– Combined Heat & Power
• Must seek interconnection agreement first!
– Solar
• Public owner challenge to share in 30% tax credit
– Understanding ownership vs Power Purchase Agreement
