2. Net metering measures both energy used from the grid and excess energy produced that is sent to the grid
FPL’s meter only measures the “excess energy” sent to the grid, not the total energy produced by the PV system

3. Net Metering / Interconnection Agreement
Renewable energy systems interconnected with the utility need a Net Metering Interconnection agreement even if they will not feed excess energy to the grid.
Net Metering / Interconnection Agreement
Net metering
A supplement to the retail tariffs which provides credit to a customer for all excess renewable energy they produce and send to the grid
Interconnection agreement
An agreement with the customer, allowing them to interconnect a renewable energy source to the grid through their internal wiring

4. Net Metering is for systems designed to offset on-site usage, not ones that are designed to produce energy in excess of consumption.
Net Metering
The Net Metering Rule was passed into state law on March 19, 2008, requiring investor-owned utilities to facilitate the interconnection of customer-owned renewable power generation.
The goal of net metering is to allow a customer to offset all or part of their energy usage at an individual metered service account.
As of June 30th 2012, FPL’s 1,894 net metered customers have MWs AC of renewable energy interconnected with the grid.

5. Renewable Energy Sources Eligible for Net Metering
The Florida Public Service Commission has defined eight renewable energy sources that are eligible for Net Metering.
Renewable Energy Sources Eligible for Net Metering
Biomass (landfill gas or methane)
Hydroelectric
Ocean energy ( tidal power or ocean currents)
Hydrogen power (fuel cells)
Waste heat
Geothermal energy
Wind energy
Photovoltaic (PV)

Reminder…..
FPL Quality & Safety Expo
April 20, 2007
Juno Beach Office
8:30 AM – 1:00 PM
Publix not attending. Perhaps Publix would consider having a team booth at this event next year to share a QI success story.

6. Net Metering Project Scope
Net Metering applies to all FPL retail customers.
Net Metering Project Scope
Promote small customer-owned renewable generation
Primarily intended to offset part or all of the customer’s load
Does not include retail purchase of electricity from third party
Third party cannot sell or lease based on kWh
Maximum size is 2 MW
No minimum for interconnect – 2 kW minimum for rebate
Sizes divided into Tier 1, 2, and 3
Requires standard interconnection agreement
Cannot exceed 90 percent of customer’s utility distribution service
Inverter UL listed for continuous interactive operation

7. Gross Power Rating AC kW = DC kW x 0.85
There are three separate Net Metering Interconnection Agreements - based on the systems Gross Power Rating.
Tiers
0 to 10 kW AC >10 to 100 kW AC >100 AC kW to 2 MW AC
Gross Power Rating AC kW = DC kW x 0.85

8. As of June 1st, FPL has 1,703 Tier 1 Customers.
Up to 10 kW AC, kW DC = AC x 0.85 (mostly residential and small business)
No charge for application or bidirectional meter
Standard application and interconnection agreement
Agreement cannot be amended
No insurance requirements
Disconnect switch not required
Cannot exceed 90 percent of allocated service size without CIAC
Must still pay monthly customer charge if 0 kWh
For governmental customers, we have a letter indicating customers liability is limited by Florida statutes
The interconnection requirements for Tier 1. Most installations are Tier 1 at this time.

9. As of June 1st, FPL has 184 Tier 2 Customers.
Over 10 kW AC up to 100 kW AC (Large residential, small and medium businesses)
$400 application fee
Standard application and interconnection agreement (non-negotiable)
Facilities review required
Visible disconnect switch required (addendum available for remote readily accessible switches)
Cannot exceed 90 percent of allocated service size without CIAC
Liability insurance requirement of at least $1 million
Liability limit for governmental customers
Interconnection requirements for Tier 2. We currently have 14 tier 2 installations.

10. As of June 1st, FPL has 7 Tier 3 Customers.
Over 100 kW up to 2 MW AC (Largest net meter) (Large businesses)
Application fee depends on system size
Standard application and interconnection agreement (non-negotiable)
May fast track or require a study
Visible disconnect switch required (addendum available for remote readily accessible switches)
Cannot exceed 90 percent of allocated service size without CIAC
Insurance required – at least $2 million
Liability limit for governmental customers
Interconnection requirements for tier 3.

11. Metering for Net Metering
A bi-directional meter is used to measure both regular usage and excess energy sent to the grid.
Metering for Net Metering
Meter code starts with:
BC (120/240 single phase)
or ends with N (all other bi-directional)
Bidirectional Meter (cycles three displays)
“+” or “POS” screen indicates customer’s energy usage
Measures energy FROM FPL
“-” or “NEG” screen - “excess energy” to FPL
NOTE: excess energy is the energy produced over and above what the home or business uses at that time and is fed back into the electric grid. It is NOT the total generation from the array. Total energy from array is shown on customers inverter.
Third screen for demand if needed
Excess energy remaining at the end of year is credited to bill at COG-1 rate
Dashes indicate meter register speed. Dashes move to the right using power from utility and move to the left supplying power to the utility.

12. Metering for Net Metering
Renewable energy systems should not be turned on until the letter is received from FPL that application process is complete . (except for testing and inspection)
Metering for Net Metering
Meter is installed after interconnection paperwork is complete
AMI meters are being developed for bi-directional applications
They are not being used at this time
Dashes indicate meter register speed. Dashes move to the right using power from utility and move to the left supplying power to the utility. 12

13. “BC” type meter (net metering)
The bi-directional meter replaces a standard meter in a standard meter base.
“BC” type meter (net metering)
Bidirectional Meter
Most common bidirectional meter.

14. “N” type meter (net metering)
Bi-directional meters are available for transformer rated meter installations.
“N” type meter (net metering)
Bidirectional Meter
Another type of bidirectional meter.

15. The most cost effective installation offsets on-site usage with all renewable energy produced.
Customer Billing
Customer always pays monthly customer charge for applicable rate even if zero consumption for the month
Customer “bank” credited on their bill at the end of each calendar year at “as available” rate (COG-1)
Approximate values: (varies with region)
The COG-1 rate paid 2.9 cents per kWh for 2011
The COG-1 rate paid 3 cents per kWh for 2010
The COG-1 rate paid 3.5 cents per kWh for 2009
The COG-1 rate paid cents per kWh for 2008
