“ Case Histories of Sustainable
Green Communities”

Seeking Energy Independence
Why????
 Dependence on Foreign oil - over
50% imported.
 Billions of Dollars Going out
 Cost of Protecting Oil sources
 Health care costs going up
 Climate change – Global warming
Saudi Arabia Looks to NREL for
Solar Monitoring Expertise
by Bill Scanlon, NREL | April 22,
2013 |
Saudi Arabia is jumping
headlong into renewable energy,
with plans to install more solar
and wind power in the next 20
years than the rest of the world
has installed to date.

Future Energy Cost?
Increase in Energy Consumption Projected to be -
• 57 % by Year 2020
• 200% to 300% by Year 2050.
Electric Power cost escalation @3%/yr
Green means.. Economic
Development.. Saving money..
Save energy & natural resources.
Create healthy and productive
environment for people.
Green Benefits ???
*Control the Budget -Energy Costs
of Municipal Operations
* Save money-avoid waste
* Improve local economy
* Conserve Natural Resources…
* improve community image with
innovation and new technology
How Communities Can Go Solar in
New York State ?
How to go green with Solar?
 New York State is promoting solarpowered public buildings and lights.
 How do we achieve this?
Solar PV works better in Cold climate.
Rochester weather better than Germany who
is world leader in solar power production
Solar power in Cold Climate of
Rochester NY is Feasible
• Germany is World’s top Solar Producer with colder
climate. New Jersey is #2 in USA
* Solar panels work better under cold and wet
conditions
• Day light is sufficient to make power ,Sunshine
makes more power in summer
• Snow melts and cleans the panels after snowfall
• Cost of PV system reduced 70% in last 5 years
• NYS has best financial incentives in the Nation
• Private Capital available to finance project
Under Power Purchase Agreement
Another Banner Year for Solar
Power: Industry Breaks Records
in 2012 .. March 14, 2013
By Jennifer Runyon, Managing Editor,
RenewableEnergyWorld.com
In 2012, the U.S. solar industry
grew 76 percent over 2011,
adding 3.3 GW of new solar
capacity.
Total U.S. PV Installed Capacity
Approaching 10 GW
(Equal to Ten Nuclear Plants)

New York Rises – 2013 Plan
 NYSERDA’s Competitive Solar
Program, PON 2589, funds solar
PV systems for public buildings.
 You can achieve net-zero energy
and rely on your own power!
 In the end, everyone wins!

Steps for Implementing
Green Community Initiatives
 Involve all major departments in assessment of
current practices
 Hold joint meetings to brainstorm ideas for
conservation and savings in operating costs
 Prepare a Work Plan with various departments
involving Engineering, Environmental, Parks,
Planning, highway, Building facilities, Purchasing
etc.
 Adopt Sustainable Green Plan and inform the
residents
 Procure Federal & State grants or incentives for
Energy Conservation/ Generation
 Set up Energy Independence goals and review
achievement date.

Energy Independence Steps?
1. How much Energy we use now?
2. What can we do to reduce the demand?
3. Determine the Kwh per year needed after
Improvements.
4. Evaluate potential technologies to make Green
Power
5. Wind Turbines- 2500 to 3000 hours per Year
6. Solar PV generation – 1100 hours per Year
7. Get solar grants and implement
energy generation measures-PON 2589 due
March and September 2013
8. Make Green Kwh per year = to Demand / yr.
EXAMPLE Avon- Town & Village
Energy Use Summary
Town of Avon :
11 accounts – 377,590 kwh/ yr.
Village of Avon :
10 active accounts- 1,262,358 Kwh/ year
Total Energy use / yr.= 1,639,948 Kwh/ yr.
Average cost of power = 9.3 cents / Kwh
Demand Charge average= 3 cents per Kwh
Energy Planning Strategy
 Adopt Vision to be Net Zero
Community
 Reduce power consumption via
energy retrofits
 Produce Green energy via Solar PV
 Small Wind Turbines where practical
 Seek grants from NYS
 Promote tourism to show Green
Energy Project.
Energy Independence Via PON
2589- Bid for Large solar PV?
1. Pursue NYSERDA grant via Bid process under
PON 2589 . Total $140M available 30% to 50%
2. Seek Letter of Interest and Qualifications from
NYSERDA approved local solar system
installers?
3. Determine the annual Kwh per year production
goal needed to serve Municipal energy
requirements.
4. Establish long term power purchase agreement
terms and state in the LOI solicitation.
5. Solar PV generation – 940 hours per Year
6. Review LOI and select preferred vendor.
7. Submit bid for NYSERDA grants by
August 29, 2013
8. Install system under PPA after
NYSERDA acceptance of bid.
Here’s how the Process works
Bid submission by applicant and approval by
NYSERDA
Finance- Design and Build PV System
Solar contractor becomes power provider under
PPA lasting up to 20 years, at a rate less than
current power provider rate
After 20 yrs the solar PV system is turned over to
the community, providing a long-term, low-cost
power solution.
The community saves money for another 20 YRS
+
=
Too good to be True? How can
Developer afford to do it?
NYSERDA grants (30%) based on
Bid for 2MW max and Federal tax
incentives for green power 30%+
depreciation benefit
Receive money from the host
municipality for electrical
consumption via PPA
NYSERDA payment source
SBC/RPS tax paid by all
consumers
What are the costs?
 Zero Capital cost. The municipality
leases the project site to the contractor
for a symbolic $100./ yr.
 Under PPA municipality buys solar power
for 10- 20 years at lower cost than the
current power provider.
 When contract expires, the municipality
buys the solar PV system back for Fair
market value and gets low-cost electricity
for another 20 years!
