• 50+ community solar facilities and growing

• In conversations with over 160 utilities

Focused solely on community-owned solar

• Built the nation’s first and largest community-owned solar facilities

• More community solar built than all other vendors combined (60%+ of all systems)

• Worldwide recognition for having the best program available

Partners in local communities to provide utility and consumer value

• Worked with utilities from small rural cooperatives to nationwide IOUs

• Fully funded, built and administered by CEC

• Provide significant investment in the community and long-term local savings

Clean Energy Collective | Community Solar


• Solar is broadly supported and desired by the public

• Community solar is the only solution that reaches the vast majority unable to do rooftop solar

• Programs can come from policy or business – legislators and utilities are increasingly pursuing

• NREL/DOE study shows $16B potential market by 2020

Community Solar | Wave of the Future

The National Renewable Energy Laboratory (NREL) recently published the SunShot-funded report “Shared Solar: Current Landscape, Market Potential, and the Impact of Federal Securities Regulation.” The report finds that a significant percentage of households and businesses are unable to host photovoltaic (PV) solar systems because they rent their spaces or have a lack of suitable owned roof space. For this customer base, community solar opportunities give them the best chance to invest in solar energy.

The report also finds that community solar could lead to cumulative U.S. PV deployment growth of 5.5 to 11.0 gigawatts between 2015 and 2020 and represent $8.2 to $16.3 billion of cumulative investment. In fact, according to the report, by the year 2020 community solar could account for up to half of the overall distributed solar market in the United States.

The White House recently launched the National Community Solar Partnership because it is the most cost effective way to deploy solar and it can be made readily available to low to moderate income communities.

What is Community Solar? | Overview

Community Solar

Creating Universal Access to Clean Energy

Your panels

Your neighbor’s panels


If a customer has an electric bill, they can participate in

community solar!

Community solar | Who can participate?


A centralized solar array on a single plot of land A centralized array

Creates local jobs and positive PR for the utility and local communities

What is Community Solar? | Overview

Array is interconnected to the utility’s grid at a choice location

Customers subscribe to a portion of the array

Subscribers own the solar panels and are credited for the energy value

Utility owns the energy and all associated benefits

The system is maintained and warrantied by CEC with no added costs, the utility can bask in the

benefits

Interconnected

Subscribers are credited for the power from their portion of the array

Utility oversees the entire process

Professionally maintained and warrantied

Creates positive PR and local jobs


Cost This is the most

important piece

Costs must line up with

utility needs and provide

benefits to customers

Must build the solar

facility at best cost

Community Solar | Three Core Components


Starting a Community Solar Program | Questions to consider

Reasons for starting a community solar program

• An affordable option for going solar

• Fill a void in the marketplace

• Allows utility to offer a solar option to their customers

• Provide the most stable, long term commitment to

renewable energy available to South Carolina citizens

What makes a community solar program succeed

• Structure that is fair to customer and utility

• Appropriate cost saving and proper payback to

customer

• Create strong customer demand

• Most successful programs offer ownership to customers

What makes a community solar program fail

• Structure that is unfair to either customer or utility

• Low cost saving and unreasonable payback to customer

• Does not focus on creating customer demand

• Programs that do not create a sense of pride

(ownership)

What do most people want

• Most people invest in community solar to save money.

• Let’s consider various Community Solar Options


Green Power Purchase Model • Participants pay for solar energy, no financial savings

• Average longevity of participation is 1.5 – 2 years

• Not widely seen as a true community solar product

“Blocks” of power for purchase • Customers buy “blocks” of power that offer a some type financial benefit

• May not reflect true panel production

• Often done through a PPA directly with customers which carries legal & administrative concerns

Lease Model (or “Shared Solar”) • Customers pay a monthly lease payment for rights to “share” a portion of an array

• There is sometimes a one-time upfront payment for your “share” of the array

• Receive credit on utility bill but usually minimal payback for participants

Ownership • Provides 7x – 8x more benefit to the customer

• Best solution for providing maximum long-term commitment to renewable energy

• People want to own their solution, not just buy power

Community Solar | Various Models


Savings for the Customers

• This makes the program successful

• 5.5% year 1 payback (minimum)

• Less than 15 years total payback

• 74% of people go solar to save money

Success for the Utility

• Minimal costs

• Control over the program

• Automated bill crediting software

• No liability & limited risk

Aligns with other Solar Solutions

• True ownership opportunity

• Benefits exceed other forms of solar

Customers engage in community solar to save money

• Programs that don’t embrace this will not achieve wide scale success

Starting a Community Solar Program | Path to Success

A Smart Solution

Energy Storage is a Smart Investment Choice

We have the opportunity to address

a myriad of grid challenges

by embedding energy storage as a critical part

of our power infrastructure.


Energy Storage Addresses Grid Challenges

Battery-based energy storage provides peaking power in a way that is distinct from traditional thermal assets.

Adding batteries:

Improves usage of existing assets Improves efficiency of existing resources

Reduces system-wide emissions

Supports integration of more renewables Instantaneous response to balance supply/demand

Improves grid reliability and security of supply Digital response adds precision

Locate generation near load

Energy Storage costs less and does more.


Additional Benefits from Energy Storage

Emission free with no water usage

Rapid deployment

No minimum generation

Always on

High reliability + availability

Can perform multiple jobs, highly utilized asset


The market’s view
