Our Energy Future

Fossil fuels helped build our economy. But now we know the harm they cause:

• Increasing costs
• Climate crisis: extreme storms, floods, fires, global warming

We must cut fossil fuels, through:

• Efficiency
• Renewable energy

Best ways to expand renewables in CT: DG, by “prosumers”

• Shared / Community Solar (and other renewables)
• Virtual Net Metering (VNM)
• Commercial Scale Solar
• Residential Solar

This presentation:

• Status of these strategies and challenges today
• What we can all do to move them forward now

Status: Residential

5000 10000 15000 20000 25000 30000

About 30,000 CT homes have gone solar

Peoples Action for Clean Energy (PACE) is meeting with towns to plan for 100%

After years of missed opportunities …

… while other states reaped the benefits of the green economy ….

The Good:

• Utilities must get more

power from renewables (RPS)

• Shared Solar Program
• Virtual Net Metering
• Commercial Solar

Incentives Extended

• Green Bank and

Efficiency Protections

The Bad:

• Limited eligibility,

caps, delay

• Still capped
• Retail rate net

metering program for rooftop solar replaced with restrictive tariff

The work ahead:

• DEEP and PURA -- proceedings on PA 18-50
• Legislature -- get fair pricing for rooftop and

commercial solar and expand shared solar

• Local -- ID shared solar sites and show demand

... 2018 saw steps forward (and backward).

2018 Progress: Shared Solar

FINALLY, CT has joined other states to start allowing everyone – especially low and moderate-income customers -- access to renewable power. BUT: lots to be worked out.

Source: PA 18-50. Section 7

Good:

• 25 mw/year for 6 years =

150mw

• Major set-asides for low-

income and low/mod income:

• 10%+ of every project

for LI customers

• Additional 10%for LI,

MI, or LI groups

• Businesses, the state,

towns, are all eligible (no more than 50% of a project can be for commercial customer)

Bad:

• Need and demand is much

more than 150mw

• “Use or lose” annual

allotment

• Other eligible customers

must demonstrate they are “unable” to do rooftop solar

• Lots to be ironed out in

DEEP and PURA proceedings over next year

• Rates unclear
• Start date January 2020

Unknown:

• Rates could be based
• n lowest bid, or cost-

plus, or combination; could be more than 1 rate

• Pilot was complicated,

risky for developers; program needs to be simpler, more doable

• What does “unable”

mean?

• Etc. etc.

We can all help move Shared Solar forward by

participating in DEEP and PURA proceedings to help develop good program rules!

Getting Ready for Shared Solar:

4 local steps we can take

1. ID sites 2. ID subscribers

• 1. Sites

Brownfields Big buildings Along highways Parking garages

250+ closed landfills in CT

• 3. Talk with developers
• 4. Prepare proposals for early 2020

Getting Ready for Shared Solar:

4 local steps we can take

• 2. Subscribers
• 800,000 potential
• Must be in the same utility service

area as the source (Eversource or UI) “Communities of interest:”

• Neighborhood residents
• Tenant or condo assn. members
• Faith group members
• Subsidized housing residents
• Chamber of Commerce members
• ______________________
• ______________________

Variety of structures:

• Non-profit
• 3rd party developer
• Co-op
• NOT: utility-owned

Getting Ready for Shared Solar:

4 local steps we can take

• 3. Talk with Developers

90+ solar companies in CT Three developers selected for Pilot:

Community Solar Access

2018 Action: Larger Solar Installs

(businesses, government, farms)

Sources: PA 18-50; CT Green Bank Comprehensive Plan, revised July 2018. Note: the market is for a range of energy efficiency services as well as renewable generation. TAM = technical potential; SAM = economic potential

A mix of opportunities and limits …

• One year of LREC and ZREC funding streams
• Capped at 50mw/year for 6 years (300 mw) total (Virtual Net Metering, commercial, government, farm)
• Annual “use or lose”
• Start date January 2020
• “Procurement” through auctions, lowest bidder, lots of uncertainties – rates, utility control
• DEEP and PURA proceedings over next year

… that ignores the potential:

Large Solar -- Virtual Net Metering (VNM)

VNM = shared solar for towns, farms and the state

2018 Action: Rollback of Residential Solar Compensation

Sources: PA 18-50; CT Green Bank Comprehensive Plan, revised July 2018, p.40-42

What Changed?

• Simple net metering (monthly

accounting, annual true-up) ends after 300 mw reached

• New solar rates one of 2 schemes:
• “Buy-All / Sell All” or
• Daily or hourly or instantaneous

power tracking

• New rates:
• Unknown, untested
• Could make it harder to load

shift, integrate storage

• Make rooftop solar less

economic

• Throw growing solar industry into

chaos

Why is this bad for CT?

• Imperils enormous potential in residential

rooftop solar

• To date:
• 30,000 solar homes
• 215 mw
• 1-2% of state’s consumption
• Potential (CT Green Bank):
• 500,000+ homes (could be

650,000+ as costs go down)

• 3,890 mw
• 22% of state’s consumption
• $12 billion investment
• 70-100,000 job years

LEGISLATIVE CORRECTION NEEDED IN 2019

• 81% - reducing pollution from power plants is a worthwhile goal.
• 76% - increasing renewable energy is a worthwhile goal.
• 70% - expect electricity to become cleaner over time.
• 53% - willing to install solar panels on their own roof or participate in a community

solar garden or array if they could recover their investment in five years.

• 48% - willing to pay $5 more per month for energy that comes from renewable

sources.

• 18% - believe that their utility company cares about lowering costs for consumers.

Consumer Reports

2018 CT Elections

“If newly elected lawmakers are looking for a bi-partisan issue that can make a big impact in their communities, they need to look no further than community solar… the community solar market can sustainably scale to 50-80 times its current size by 2030

• r to 57-84 GW. … 9 million new solar customers, including 4 million low-to-

moderate income customers … $120 billion in capital investment in new local energy infrastructure …. a win-win-win for customers, the grid, and the environment.”

• - Coalition for Community Solar Access (CCSA), 11/8/18 (bold added)

New Governor: Energy and Technology Committee:

• New leaders, new members

House and Senate:

• More favorable

“I will streamline our state’s community solar permitting process and virtual net metering rules to sped construction of medium-to-large solar installations over brownfields, parking lots and warehouses..”

“Combined Public Benefit Charge” 1.3 cents/kwh:

• System Benefits Charge
• 6/10 of a cent /kwh
• Conservation Charge -

3/10 of a cent/kwh

• Conservation

Adjustment Mechanism – 3/10 of a cent/kwh

• Renewable Energy

Charge - 1/10th of a cent per kwh (26 cents in this example)

But we don’t all benefit

from the Residential Solar Incentive Program

Hartford and East Hartford pay more, get less.

New Haven pays more, gets less.

Meriden, Middletown pay more, get less.

Our Goal:

Full statewide shared renewables – so EVERYONE has access to clean energy

How will we get there?

• 1. Spread the word!

I want solar, please!

• Tell friends and family about new
• pportunities
• Letters to the editor, to Legislators
• Ask legislators where they stand
• Invite us to speak to your group
• Engage town groups and leaders about

sites and subscribers “We are the leaders we’ve been waiting for.”

How will we get there?

• 2. Town resolutions: call on legislators to support

shared solar, VNM, fair pricing for solar

CFE can help:

 Model resolutions  Organizing tips  Local contacts

“When people lead, the leaders will follow.”

How will we get there?

• 3. Sign up. Get informed. Stay in touch.
