• Energy efficiency programs have helped keep per capita electricity consumption in California flat since 1976

• PG&E’s programs alone have avoided the release of over 135 million tons of CO2 into the atmosphere over the same period

30+ Years of Energy Efficiency Success

Note: 2005 – 2008 are forecast data.

22

ClimateSmart• The energy you use emits

greenhouse gases, such as carbon dioxide (CO2), into the atmosphere.

• ClimateSmart is a voluntary program that enables customers to reduce their impact on climate change.

• Customers can pay a separate amount on their monthly energy bill to make your home energy use "climate neutral.“

• PG&E will invest 100% of the payment in independently verified greenhouse gas emission reduction projects in California

23

How it Works• These projects absorb or reduce over time an equal amount of CO2 from

the atmosphere, balancing out the climate impact of your energy use.– Conserving and restoring forests– Capturing methane gas from dairy farms and landfills– Many more proposed

Example of Projects:

Forestry

• Carbon sequestration• Habitat preservation• Watershed protection• CA is losing 40,000

acres of forestland annually

Dairy Methane Capture *

• Reduce impact of methane• Of 1900 dairies in CA,

unless than 24 capture methane

Landfill Methane Capture **

• Reduce impact of methane

* Pending CPUC approval.** Requesting CPUC approval.

24

ClimateSmartEnrollment is easy and voluntary; customers can

choose to enroll their electric or gas or both accounts

Cost/Rates• Based on actual usage (how many kWh and/or therms are used)• Electric: $0.00254 per kWh• Gas: $0.06528 per therm• Less than $5 per month for a typical residential home• Contributions are tax deductible

What is CSI?• The California Solar Initiative provides a financial

incentive for the installation of solar on a home or business.

• CSI incentives vary by incentive type, customer segment and system size.

• Incentive amounts gradually reduce over time.

• First funding is reserved, then once installation is complete, the incentive payment is made.

30

CSI Eligibility• Project site must be in service area receiving retail electric service

from Pacific Gas & Electric (PG&E), Southern California Edison (SCE) or San Diego Gas & Electric (administered by CCSE)*• CSI incentive rate determined by customer’s utility rate schedule

• Retrofit Residential Projects (Single Family & Multifamily homes)**• Retrofit and New Construction Non-Residential Projects

(Commercial, Industrial, Agricultural and Government)• Must use new and eligible equipment approved on CEC list

• Note: Effective July 1, 2009 there is a new list for eligible PV modules based on testing standards

• New panels can be added to an existing inverter, if that inverter was previously rebated through the CSI (or program under SB1).

• Minimum System Size of 1 kW• Maximum System Size of 5 MW

• Incentives will be capped to the First MW*Municipal electric utility customers, please check with your provider for any solar incentives or CSI updates. ** New construction residential projects are eligible under the New Solar Homes Partnership Program

31

CSI Eligibility• Installation contractors must have valid A, B, C-10 or C-46

license and be listed with the California Energy Commission, unless it is a self-installation• Can be verified by contacting the California State License Board at

www.cslb.ca.gov or 1-800-321-2752.

• System production must serve onsite electric load• For system 5kW or greater: Estimated production from EPBB

calculator must be < previous 12 month usage history (kWh)• If system cannot be justified by historical usage, one of the

following documentation must be provided:1. Square Footage (only system size of 5-9.9 kW), will be used to

calculate allowable size (2 watts x square feet = maximum CEC-AC system size)

2. Comprehensive list of new and/or old appliances/equipment, wattage and expected usage or hours of operation

3. Other: engineering calculations, Title 24 (no older than 3 years), or building simulation reports such as eQuest, EnergyPro, etc

32

CSI Eligibility• Energy Efficiency Requirements

• Energy Audit must be completed• All Customers must sign a Disclosure Agreement*

• Acknowledgement that usage history/building information, energy efficiency measures and recommendations have been provided.

• Benchmarking (only for Non-Res over 100,000 sq/ft, EPBB only)*• Comparison of energy consumption of a similar building to determine a

rating/performance score• If customer’s rating is less than 75, retrocommissioning must be completed.

• Customers required to sign Commitment Agreement• Commits customer to perform retrocommissioning and complete

improvements identified in assessment• Improvements must be completed before a project is paid

• Non-Residential New Construction must be 15% above current Title 24 Standards*

*Effective July 1, 2009

33

CSI Incentive StructureThere are two types of Incentives:

Expected Performance-Based Buydown (EPBB)• EPBB is a one time, up-front payment based on an

estimate of the system's future performance

Or…

Performance-Based Incentives (PBI)*• PBI are monthly payments for 5 years based on actual

performance of the system as measured by a separate performance meter

*Any system larger than 50 kW are required to select for the PBI Incentive**Effective January 1, 2010 any system larger than 30kW are required to

select the PBI Incentive

34

CSI Incentive RatesIncentive structure:• 10 step program with a predetermined number of MegaWatts dedicated to each

Step Level • Rebates automatically decline based upon reservations approval• Higher rebates for non-taxable entities (Government/Non Profit)

38

EPBB Calculator

39

EPBB Calculator• Online tool that estimates the expected production of

the system and is used to determine the CSI incentive amount

• Takes into consideration equipment, location, orientation, tilt, shading effects and standoff height

• Measures the proposed system against an optimal system

• Derates the proposed system by a certain percentage (0-100%), referred to as the Design Factor, for any factors affecting the expected performance.

40

Filling Out the EPBB Calculator

• Required Field Measurements

• Standoff Height

• Shading

• Tilt

• True Azimuth

41

Standoff Height• Standoff Height - perpendicular distance from roof to the

bottom of the module frame• If not parallel to roof, use average height as shown below

Frame

6”

3”

(6”+3”)/2=4.5”

>0” to 1”

>1” to 3”

>3” to 6”

>6”

Please note: If the Mounting Method is not selected on the EPBB Calculator, it will automatically default to greater than 6” which can result in an incorrect design factor

42

Minimal Shading and Solar AccessObstructions such as trees, chimneys or nearby buildings can cast shadows on PV systems, which can reduce the system’s sun access thereby reducing the amount of electricity the system will generate.

You must indicate on the EPBB Calculator whether there is shading that will have an impact or not.

Option 1: Minimal Shading

• Minimal Shading-requires at least a 2:1 distance to height ratio of any object within the orientation of sun to the panels.

A

B

A > (2 X B)For example, if line B is 13 feet, then

line A has to be 26 feet or more

Object Height is 15 feet above the array.Object Distance is 25 feet from the array.2 x Height (above the modules) = 2 x 15 feet = 30 feet2 x Height < Distance = Minimal ShadingIs 30 feet < 25 feet? Is this Minimal Shading?

SHADE IMPACT REQUIRED

15 FeetNO

45

If Not Minimal Shading…Option 2: Not Minimal Shading, Enter Solar Access Values

• If a system does not satisfy the minimal shading requirement, a shading analysis needs to be performed to generate monthly solaraccess values.

• Solar access can be measured with tools such as the Solar Pathfinder or Solmetric SunEye (available at Pacific Energy Center to loan, visit www.pge.com/myhome/edusafety/workshopstraining/pec/toolbox/tll/)

• Measurements should be take at every major corner, but should not be more than 40 feet apart.

46

Sample Reading

47

Shade Impact Comparison: EPBB vs PBI

PBI• Incentive based on actual kWh generation• Since entire year’s system availability affects kWh

generation, all shade including winter shade affects incentive

EPBB• Only summer months (May-October) solar access

affects incentive• Winter shade has no impact on incentive

48

Tilt

• Tilt - Angle at which the modules are mounted relative to 0º(flat horizontal surface)

• Modules that are installed on a flat roof will have a 0º tilt

tilt angleº

Frame

Ex. 30º

49

What is True Azimuth?True Azimuth – the angle, usually measured in degrees(°), between a reference point (True

North Point 0°) and the direction of interest (direction panels are facing)

• The magnetic azimuth is measured using a compass, which does not represent the true north point because of the Earth’s magnetic fields

• Therefore, the magnetic azimuth must be corrected by adding (in Western U.S.) the magnetic declination of a specific location to give true azimuth

Magnetic DeclinationMagnetic North on a

Compass

50

Magnetic Declination Correction• Look up magnetic declination for specific location at:

(http://www.ngdc.noaa.gov/geomagmodels/Declination.jsp)• Enter in zip code, and it will calculate the magnetic declination for that

location.

For example:

If you are in San Francisco and your compass shows you a reading of 180°,

you would look up the zip code (e.g. 94105) and add the given correction for

magnetic declination of 14° to get a true azimuth of 194°

On EPBB Calculator, enter the azimuth as 194°

51

Tips for Determining Azimuth• Try to stay 10-15 ft away from metal, motors,

rooftop package units or magnets

• Store compasses away from cell phones and magnets

• Do not place compass directly on module or racking in case there are any magnetic fields present

• Check reading against tools like GoogleEarth. There is no azimuth function, but it can be used to provide sanity check for azimuth.

52

EPBB Tool Demonstration

www.csi-epbb.com

We will show how to input a sample system

EPBB Tool explanation sheet can be found online at www.pge.com/solareducation

53

Using the EPBB Calculator:Incentive Amounts

EPBB Incentive = EPBB Incentive Rate x CSI rating

• CSI rating = CEC-AC Rating x Design Factor

PBI Incentive = PBI Incentive Rate X Actualmonthly kWh output*

• EPBB calculator will give estimate of the incentive for PBI by calculating estimated annual output (annual kWh) x the incentive rate x 5 years

* As reported monthly by a separate performance meter

54

Field Verification• Field measurements should be verified pre and post

installation for accuracy• If changes have been made after installation is complete,

a new EPBB calculator must be submitted• The following measurements must also be verified in

the field post installation by the contractor*• Primary Method

• Solar Irradiance• Temperature• Inverter Output

• Compare to Field Verification Output Table (next page)• Secondary Method (trained/certified professionals only)

• Polarity of all source circuits is correct• Open circuit voltages of source circuits have been tested

and measured to be within 2% of each other• Short circuit currents have been tested and measured to be

within 5% of each other*Effective for Reservation Request Applications first received on or after July 1, 2009

Multiple EPBB Calculators• Multiple EPBB Calculators are needed when there

are multiple arrays that differ in one or more of the following:• Stand-off Height

• Shading

• Tilt

• True Azimuth

• Panel manufacturer and/or model

• Inverter manufacturer and/or model

CSI Field Inspection Process

91

CSI Field Verification Inspections

Purpose• To verify that the project is installed as represented in

the Incentive Claim Form, is operational, is interconnected and meets the eligibility criteria of the CSI Program.

92

Selection of CSI Projects for Site Inspections

Projects <50 kW:

• First two Incentive Claim Forms submitted by a contractor will be inspected

• After two successful inspections, projects will be randomly chosen for inspection

• Random means approximately 1 in 7 applications per applicant

Projects >50 kW:

• Program administrator’s discretion

93

CSI Inspection Verification

Inspectors will verify the following:Module & Inverter Equipment

- Manufacturer

- Model Number

- Quantity

*If module nameplate is not visible, invoice is necessary to verify manufacturer and model

Installation Parameters Verified

Measure:

- Tilt

- Azimuth

- Standoff Height

- Shading of array(s)

Operation

- System is operational, and output is reasonable for conditions at time of inspection

94

Coordination of InspectionsApplicants are not required to attend inspections, though they are highly encouraged to do so, especially…

• For first time Applicants

• For projects with significant shading

Inspector will require physical access to the equipment

• Inspectors prefer that the Applicant coordinates with the Host Customer to allow access

• If Applicant prefers, the Inspector will coordinate with the Host Customer.

95

Access Issues to ModulesIf issues exist that prohibit access, such as

• Weather conditions that may render it unsafe to mount roof

• Roof that are too steep or have other structural issues, etc.

We will require assistance from Applicant by

• Providing Inspector shading analysis for EPBB Calculator

• Providing Inspector invoice indicating the module manufacturer, model and quantity

Inspector will still verify if the system output from the inverter is reasonable given the conditions during the inspection

96

Inspection Results• Inspector will verify measurements are within the following tolerances:

• Tilt +/- 3º

• Azimuth +/- 5º

• Shading +/- 5%

• If inspection results fall within tolerances• Inspector will accept EPBB calculator as submitted with the Incentive

Claim Form and send report to PG&E• PG&E will pay incentive as requested in the Incentive Claim Form

• If inspection results fall outside of tolerances• Inspector will communicate discrepancies to Applicant onsite, if present

during inspection• Inspector will run a new EPBB calculator to get a revised CSI rating and

incentive amount• Inspector will send it along with the report to PG&E for further evaluation

97

Inspection Results Cont’d• PG&E will compare recalculated incentive to submitted

incentive amount in Incentive Claim Form/EPBB Calc.• If incentive amount discrepancy is within 5%

• PG&E will pay revised incentive amount based on new EPBB Calculator from inspection

• If incentive amount discrepancy is 5% or more• PG&E will issue a failure

• If a failure is issued, the following two options will be communicated to the Applicant and Host Customer and a decision must be made within 30 days:

1. Applicant can accept new recalculated incentive amount2. Applicant can dispute the accuracy of results/measurements

• If installed equipment is different (manuf/model or quantity) than that submitted in the ICF/EPBB Calc, new EPBB calculator will be run if it effects CSI rating/incentive

98

Failed Inspections

• Low volume Installer (< 200 systems per year Statewide)• 1 failure = warning• 2 failures = 100% inspection for Applicant’s projects• 3 failures = Disqualification for 1 year from CSI Program

• High volume Installer (> 200 systems per year Statewide)• 4 failures = 100% inspection• 5 failures = Disqualification for 1 year

• All failures removed after good standing for 1 year of last failure

99

How to Prevent Failed Inspections

• Make sure Incentive Claim Form and EPBB Calculator accurately reflect “as-built” system

• If any changes occur, send updated EPBB Calculator to

Program Administrator before the inspection occurs

• Revised EPBB Calculators will not be accepted by Inspectors

on-site

• Attend the inspection to familiarize yourself with the inspection

process and program requirements

CSI Performance Meteringand Monitoring

102

Performance Metering and MonitoringCPUC requires all projects to have Performance Monitoring and

Reporting Services (PMRS), unless exemption criteria are met

EPBB and PBI Projects• Performance Meter: is a meter separate from and in addition to the

utility’s revenue meter (can be inverter integrated) and records system performance at an accuracy of +/-5%.

• Performance Monitoring and Reporting Service (PMRS): is a service that a customer can purchase to track the performance of their system through the performance meter or a NGOM.

PBI Only• Net Generation Output Meter (NGOM): is a meter separate from and

in addition to the utility’s revenue meter and records performance (output) data at accuracy of +/-2%.

• Performance Data Provider (PDP): the entity that collects performance data from the NGOM and provides it to PG&E. This is used for calculating monthly PBI payments and can also be used to provide customer performance data.• Data for PBI payments is collected once a month

• Overview– A definition: All solar technologies other than flat-plate

non-concentrating modules• In other words: Anything other than conventional PV

– As of October 1, 2008, other solar electric technologies could apply for CSI incentive

– Reflects CPUC intent that all solar technologies (not just PV) should qualify for incentives

– All “Other Solar Electric” incentives are PBI– As with PV, products must be certified for CSI eligibility

• Only one product certified to-date (SolFocus)

Generation Interconnection Services (GIS)

115

Interconnection OverviewInterconnection is the physical connection of the solar system to the utility grid.

GIS Role• Coordinates interconnection activities, including:

• engineering reviews, • metering • access issues• special facilities• execute contracts and administer

• Assures that safety protocols are adhered to for the protection of the utility workers and the generator is installed as designed and operating according to Rule 21.

• Issues Permission to Operate (PTO).

• Provides for two types of solar interconnections (Rule 21): NEM (exporting) and non-NEM (non-exporting) options for the customer.

116

Total PG&E NEM Interconnections

117

Interconnection Application vs. CSI Application

• Interconnection Application is a separate, but parallel process to CSI/SGIP Application.

• Equipment submitted with the CSI application and the Interconnection Application must match.

• Permanent Service must be established (No Temporary).• GIS Field Inspection and Interconnection Agreement must be

complete and PTO granted before paid for CSI Incentive.

118

GIS Application Common Issues

• Final building permit (BP) does not match application or is missing.

• Single Line Diagram (SLD) has no equipment information: make, model, rating, or… how many PV modules are connected to each inverter.

• Name on application does not match name on PG&E Blue Bill account. (Call:1-877-743-4112 to add name to acct).

• Reprogramming fee of $228 for Time of use (TOU) not included. Website has availability and exceptions.

119

Other Common Issues• System Upgrades: New Application is necessary showing all

generation on site.

• Fax coversheet with Reference/Application number is not included when faxing docs (building permits) to GIS.

• Access to the self contained meter or the A/C Disconnect is not provided prior to the PG&E Final Inspection.

• Customer/Vendor requesting “courtesy calls” upon PG&E receipt of final City/County Building Inspection.

• Appointments for installation of a PG&E lockbox to gain access not discussed with customer by the vendor.

120

#1 Issue

• Disconnect Access: Customer’s bi-directional meter must be installed in a safe, 24/7 PG&E-accessible location, unobstructed by locked gates or pets. Meter access must be maintained at all times for reading/system maintenance. Any animals owned by the customer, including pet dogs, should not have access to these areas to avoid hindering PG&E service personnel from completing their work.

• PG&E Rule 21(D.1.e) requires PG&E to have a visible, lockable, accessible A/C disconnect device for each generator. It is not required if the customer has a self contained meter that can be utilized as the A/C disconnect for the generator. (98% of PG&E meters are self contained).

121

Net Energy Metering (NEM)

Electricity can be “exported” to the grid by the customer.PG&E can provide any extra electricity or back-up power the customer may need.

• Eliminates the need for batteries

• Reduces cost and maintenance.

• Ensures a constant supply of electricity.X

The utility grid is a two-way street.

122

Net Energy Metering (NEM)

• The intent of the NEM program is that the generation is primarily to offset part or all of the customer’s own electrical requirements.

• The electric grid acts as a "battery" for the customer and their meter measures the net usage ("spins backwards" when the customer is exporting electricity to the grid).

• In California, systems up to 1 MW can participate in the program; other states typically have a lower size limit.

Billing and Rates

126

How NEM Billing Works• Meter runs forwards/backwards and only records “net

energy”

• PG&E will not pay cash or issue a check for exporting to the grid

• Customer receives a monthly charge or credit based on electric rate schedule

• Charges/credits carry over each month for 12 months, referred to as “True-Up Period”

127

NEM Billing continued

• True-Up Period starts on date of interconnection and ends each anniversary

• At end of 12 month period, customer will receive True-Up bill, reconciling all the accumulated charges and credits

• Customer will still receive a monthly bill for minimum charge and if applicable, for gas

• Customer also receive a separate monthly NEM statement detailing reads and charges/credits to be owed at the end of the True-Up Period

128

Sample Bill and Statement

NEM Not for Everyone

• Not every customer will benefit from participating in NEM

• Reasons:• Will never export• Demand charges are not eliminated• 12 month billing cycle may be difficult for

accounting or budgets• Should be evaluated on a case by case basis

130

Residential Electric Rates• Customers are billed on a tiered pricing structure.

• The 1st Tier represents the essential amount of electricity called “baseline”

• Baseline amount is set by legislature and is based on:• Geographic location (Territory)• Season (Winter/Summer)• Permanent Heating Source (Gas/Electric)

131

Residential Rate Options

E-1• Basic rate • Price does not vary by

season or time of day• Best for customer who

are home during the day or cannot shift usage outside 1-7pm

E6• Time of Use (TOU) rate• Price varies by time of

day• 3 time periods:

– Peak– Partial-Peak – Off-Peak

• “Solar Friendly”

132

E-6 Time Periods

133

Example of Billing: E1Customer lives in San Francisco (territory T) and has gas heating

Baseline Quantity (kwh): Summer - 8.3 per day Winter - 9.8 per day30 days in billing cycle = 30 x 8.3 = 249 kwh = monthly baseline

E1

Customer’s net usage is 400 kWh Net

Tier 1 (Baseline): 249 x $0.11550 = $28.76

Tier 2 101%-130% of Baseline: 74.7 x $0.13131 = $9.81

Tier 3 131%-200% of Baseline: 76.3 x $0.24725 = $18.87

Tier 4 201% - 300% of Baseline: 0 x $0.35443

Tier 5 Over 300% of Baseline: 0 x $0.41059

Total = $57.44

134

Example of Billing: E6Same customer and usage as E1 example: monthly baseline = 249 kwh
