Why Solar? RFP Process Overview

2008 – AMS roof plumbed for solar as part of the renovation project

2011 – Avon Energy Plan identifies solar as a viable renewable option to go green, reduce operating costs, and achieve goals.

Summer/Fall 2013 – Town/BOE staff and ACEC met with CCM to discuss Solar RFP

Fall 2013 – Murtha Cullina engaged to manage RFP process January 31, 2014 – 9 proposals received / reviewed by Murtha February/March 2014 – Town/BOE interview three firms;

SolarCity selected as preferred vendor April 2014 – seek approvals from elected boards to proceed

What is a PPA?

Power Purchase Agreements (PPA) are long-term contracts to buy electricity at a predetermined rate

Developer absorbs the costs of proposal, design, construction, operation, and maintenance of the system

Customer typically realizes energy cost savings over the length of the contract

Customer stays attached to the electric grid for the balance of their power needs

Key PPA Terms

15 year PPA to match expected life of roofs and roof warranties

Suitability of roofs is certified by a third party structural engineer (at SolarCity’s expense)

Zero maintenance costs Performance risk stays with developer Multiple buy out options

– Option to have systems removed by SolarCity at no cost at end of 15 year PPA terms

– Option to purchase systems from SolarCity at fair market value to capture residual value in out years

What is a PPA? (cont.)

Avon’s Comprehensive Energy Management Plan provides the following explanation of Power Purchase Agreements as vehicles to achieve energy savings:

“While not a capital project funding mechanism, per se, power purchase agreements (“PPAs”) are being increasingly used by public and private entities to secure renewable energy, and most typically solar generated electricity, though PPAs are also executed for wind and landfill gas projects.

The Town would execute a PPA with a private company that would purchase, install, own, maintain and operate a renewable energy project at a Town facility. The Town would agree to purchase the power produced by the project at an agreed upon price over some number.”

Why use a PPA?

Zero upfront costs Hedge against future electricity costs No operations & maintenance costs No performance risk No increase in insurance Typically immediate energy cost savings Third party monitors and maintains the system

Benefits

Cost avoidance– Estimated at $350,000+ over 15 years – Approximately $23,000 / year– Projects at AHS, AMS, and DPW

Meet Energy Goals– 15% more efficient by 2015 (on a square foot basis)– 20% Carbon Footprint reduction by 2020– Integrate real technology (solar) into curriculum

Energy Diversification– Geothermal system at AFPL– Conversion from oil to natural gas across Town/BOE sites– Energy efficiency upgrades– Behavior modification

Recommendation

SolarCity– Largest solar installer in the United States– +$4.0 billion in available project financing– Significant Connecticut municipal experience– Proposed installation at AMS, AHS (new roof sections) and

DPW– Competitive ZREC bid ($85) and PPA price (7.4 to 10.2

cents per kwh over the life of the PPA)

Cost Avoidance

AHS– Total savings estimated at $171,622 or $11,441/year– Year 1 production = 362,700 kwh

AMS– Total savings estimated at $129,191 or $$8,613/year– Year 1 production = 200,200 kwh

DPW– Total savings estimated at $51,782 or $3,452/year– Year 1 production = 98,982 kwh
