15 Energy Efficiency Rebates PG&E offers a variety of rebates on gas and electric products for businesses: Agricultural Products Appliances and General Improvement Food Service Heating, Ventilation and Air Conditioning (HVAC) Lighting Refrigeration Boilers and Water Heating Business Computing 15

16 (Non-Residential Retrofit - NRR) Incentives for the installation of high-efficiency equipment or systems Customized rebates that are calculated based on actual reduction in energy usage Non-Residential New Construction The program offers owners and their design teams analysis and resources to aid with energy-efficient facility design (10-15% above Title 24) of new nonresidential facilities, expansions, or any added load Offers Energy-Efficiency Design Assistance at no cost 16

17 Retrocommissioning (RCx) Systematic process for identifying less-than-optimal performance in an existing facility s equipment and control systems Focuses on making necessary repairs or enhancements to existing equipment and systems to save energy and cost Can reduce energy costs by 5-15% PG&E provides incentives, engineering resources Building owners must agree to implement measures within 12 months 17

18 Demand Response Programs Programs that offer incentives for businesses who reduce their energy load during peak demand Demand Response vs. Energy Efficiency 24-hour demand profile period for an office building Demand Response Standard Energy Efficient Watts per square foot

19 Example of Demand Response Program PeakChoice TM PeakChoice allows customers to create a semi-customized program by selecting options from a list of features Reduction Amount & Commitment Level How many kw you can reduce Making a best effort to reduce vs. committing to reduce Event Notification Lead Time Minimum notice you need before you reduce energy Maximum Number of Events Number of events you will participate in Event Duration Number of hours you have to reduce for each event Event Window What time of day an event can occur Number of Consecutive Event Days Number of consecutive event-days you can participate in 19

20 30+ Years of Energy Efficiency Success 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 CO 2 into the atmosphere over the same period KWh/person 14,000 12,000 10,000 8,000 6,000 4,000 2, Courtesy Art Rosenfeld, California Energy Commission US CA Western Europe Note: are forecast data. 20

21 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 PG&E will invest 100% of the payment in independently verified greenhouse gas emission reduction projects in California 21

22 ClimateSmart 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 Dairy Methane Capture * Landfill Methane Capture ** Carbon sequestration Habitat preservation Watershed protection CA is losing 40,000 acres of forestland annually Reduce impact of methane Of 1900 dairies in CA, unless than 24 capture methane Reduce impact of methane * Pending CPUC approval. ** Requesting CPUC approval. 22

23 ClimateSmart Enrollment 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: $ per kwh Gas: $ per therm Less than $5 per month for a typical residential home Contributions are tax deductible Visit the PG&E website to enroll or for more information 23

25 BONUS: What are the three parts of PG&E s Integrated Approach?

26 Overview of the California Solar Initiative (CSI)

27 SB 1 CPUC (CA Public Utilities Commission) CEC (California Energy Commission) Retrofit Residential Retrofit Commercial Commercial New Construction Retrofit Low Income Residential New Construction 1. California Solar Initiative (CSI) Low Income Solar (LISP) 4. New Solar Homes Partnership (NSHP) 2. Multi-family 3. Single Family Program Administrators Grid Alternatives Program Administrators PG&E SCE CCSE PG&E SCE SDG&E BVES 27

28 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. 28

29 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 29

30 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 or 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 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 30

31 Energy Efficiency Requirements Energy Audit must be completed CSI Eligibility 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,

32 CSI Incentive Structure There 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 32

33 CSI Incentive Rates Incentive 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) PG&E (MW) EPBB Payments (per Watt) PBI Payments (per kwh) Step Res Non- Res Residential Commercial Gov't / Nonprofit Residential Commercial Gov't / Nonprofit n/a n/a n/a n/a n/a n/a $2.50 $2.50 $3.25 $0.39 $0.39 $ $2.20 $2.20 $2.95 $0.34 $0.34 $ $1.90 $1.90 $2.65 $0.26 $0.26 $0.37 Res Non Res $1.55 $1.55 $2.30 $0.22 $0.22 $ $1.10 $1.10 $1.85 $0.15 $0.15 $ $0.65 $0.65 $1.40 $0.09 $0.09 $ $0.35 $0.35 $1.10 $0.05 $0.05 $ $0.25 $0.25 $0.90 $0.03 $0.03 $ $0.20 $0.20 $0.70 $0.03 $0.03 $

35 Solar to Date PG&E territory represents more grid-tied solar systems than any other utility in the United States CSI Program success Approximately 18,500 Applications Received Over 12,500 Projects Completed totaling over $275 Million in incentives paid Continuous improvements made to streamline process and to make PowerClerk user friendly Reduced paperwork by more than 50% Working towards going paperless in the future 35

36 BONUS: What is the maximum and minimum system size to be eligible for a CSI incentive?

37 EPBB Calculator

38 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. 38

39 Filling Out the EPBB Calculator Required Field Measurements Standoff Height Shading Tilt True Azimuth 39

40 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 6 (SMAX) Frame (6 +3 )/2=4.5 Mounting Method Choices: 0 >0 to 1 >1 to 3 >3 to 6 >6 (SMIN) 3 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 40

41 Minimal Shading and Solar Access Obstructions 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 > (2 X B) For example, if line B is 13 feet, then line A has to be 26 feet or more A B 41

42 Minimally Shaded? YES 40 Feet 10 Feet Object Height is 10 feet above the array. Object Distance is 40 feet from the array. 2 x Height (above the modules) = 2 x 10 feet = 20 feet 2 x Height < Distance = Minimal Shading Is 20 feet < 40 feet? Is this Minimal Shading? NO SHADE IMPACT REQUIRED 42

43 Minimally Shaded? NO 15 Feet 25 Feet 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 feet 2 x Height < Distance = Minimal Shading Is 30 feet < 25 feet? Is this Minimal Shading? SHADE IMPACT REQUIRED 43

44 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 solar access values. Solar access can be measured with tools such as the Solar Pathfinder or Solmetric SunEye (available at Pacific Energy Center to loan, visit Measurements should be take at every major corner, but should not be more than 40 feet apart. 44

45 Sample Reading 45

46 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 46

47 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 Frame Ex. 30º tilt angleº 47

48 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 Declination Magnetic North on a Compass 48

49 Magnetic Declination Correction Look up magnetic declination for specific location at: ( 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 ) and add the given correction for magnetic declination of 14 to get a true azimuth of 194 On EPBB Calculator, enter the azimuth as

50 Tips for Determining Azimuth Try to stay 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. 50

51 EPBB Tool Demonstration We will show how to input a sample system EPBB Tool explanation sheet can be found online at 51

52 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 Actual monthly 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 52

53 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,

55 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 55

56 Case Study 1 One array with the same: modules and inverter(s) stand-off height shading azimuth tilt 1 Take 4 SunEye Snapshots, one at each corner of the array panels: Azimuth - South 180º Tilt - 21º from horizontal Neighbor s tree 56

57 Case Study 1: Calculate Solar Access Averages Each snapshot will generate 12 monthly Solar access values Array 1: Solar access values are averaged for points 1-4 Jan 84% Feb 89% Mar 92% Apr 93% May 94% June 95% July 97% Aug 96% Sept 94% Oct 92% Nov 91% Dec 89% 57

58 Case Study 1: Calculate Impact Because entire array has the same stand-off height, shading, azimuth, tilt and equipment, it is fine to complete only one EPBB Calculator using averaged monthly solar access values from the 4 points. Array has 28 panels 58

59 Case Study 2 Two arrays with the same module types and same inverter(s) Two arrays with different shading, azimuths and tilts panels: Take 8 SunEye Snapshots, one at each corner of each array Azimuth - East 90º Tilt - 17º from horizontal panels: Azimuth - South 180º Tilt Neighbor s tree - 21º from horizontal 59

60 Array 1: Solar access values are averaged for points 1-4 Case Study 2: Calculate Solar Access Averages Each snapshot will generate 12 monthly Solar access values Jan 89 Feb 90 Mar 92 Apr 93 May 94 June 95 July 97 Aug 96 Sept 94 Oct 92 Nov 91 Dec 89 Array 2: Solar access values are averaged for points 5-8 Jan 90 Feb 91 Mar 92 Apr 93 May 94 June 95 July 96 Aug 96 Sept 95 Oct 93 Nov 92 Dec 91 60

61 Case Study 2: Calculate Impact Because the two arrays have the different shading azimuths and tilts, two separate EPBB Calculator submittals are required - one for each array of unique orientation. Array #1 has 9 panels Array # 2 has 21 panels 61

88 CSI Field Inspection Process

89 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. 89

90 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 90

91 Module & Inverter Equipment CSI Inspection Verification Inspectors will verify the following: Installation Parameters Verified Operation - Manufacturer - Model Number - Quantity *If module nameplate is not visible, invoice is necessary to verify manufacturer and model Measure: - Tilt - Azimuth - Standoff Height - Shading of array(s) -System is operational, and output is reasonable for conditions at time of inspection 91

92 Coordination of Inspections Applicants 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 and will contact the Applicant to coordinate this with the Host Customer If Applicant prefers, the Inspector can coordinate with the Host Customer directly. 92

93 Access Issues to Modules If 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. The Inspector will require assistance from Applicant by Providing their shading analysis for EPBB Calculator Providing an invoice indicating the module manufacturer, model and quantity The Inspector will still verify if the system output from the inverter is reasonable given the conditions during the inspection 93

94 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 94

95 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 amount 2. 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 95

96 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 96

97 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 97

99 CSI Performance Metering and Monitoring

100 Performance Metering and Monitoring CPUC 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 100

101 CSI Application Requirements EPBB Projects: must include proof of exemption (if exempt, see chart below) Copy of quote from eligible provider showing total cost PBI Projects: must include a copy of an executed contract with a PMRS/PDP provider for 5 years and must show Provider name, project site, cost and all other terms CEC approved meter make, model and serial number Copy of signatures for all involved parties Please Note: All metering systems are paid for at the System Owner s expense including some form of communications (internet), performance monitoring and reporting capability. 101

102 EPBB Metering and Monitoring Set-Up PV Panels Project Site Inverter (with Integrated meter +/- 5%) Performance Monitoring and Reporting Service (PMRS) Customer NEM Utility Meter (Bidirectional) For Billing 102

103 PBI Metering and Monitoring Set-Up Project Site NEM Utility Meter (Bi-directional) PV Panels Inverter (with Integrated Meter +/- 5%) For Billing Performance Monitoring and Reporting Service (PMRS) Customer Net Generation Output Meter (NGOM +/- 2%) Performance Data Provider (PDP) For PBI Payments 103

104 Additional Requirements All PMRS/PDP providers must be listed on the CEC Website and be approved by each Program Administrator A list is available at Note: In most cases, the PMRS provider and PDP provider will be the same entity. Meter and equipment must be on approved CEC list If the following message is displayed on the EPBB calculator, the selected inverter does not have a +/-5% integrated meter and/or an output display. Therefore, an additional meter or component must be installed Meters must have a one-year warranty Performance meters can be installed by the utility or a qualified 3 rd party (PBI Only) See CSI Handbook: Appendix B, Section 11 and for more information 104

111 Generation Interconnection Services (GIS)

112 Interconnection Overview Interconnection 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- 112 NEM (non-exporting) options for the customer.

113 Total PG&E NEM Interconnections 113

114 Interconnection Application vs. CSI Application Submit CSI Application Review Incentive Paid Submit Interconnection Application Review & Approve Interconnect to grid 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. 114

115 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: to add name to acct). Reprogramming fee of $228 for Time of use (TOU) not included. Website has availability and exceptions. 115

116 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. 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. 116

117 #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). 117

118 Net Energy Metering (NEM) The utility grid is a two-way street. 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 118

119 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. 119

122 Billing and Rates

123 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 123

124 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 124

125 Sample Bill and Statement Jane Sample 123 Main St San Jose, CA

126 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 126

127 Residential Electric Rates Customers are billed on a tiered pricing structure. The 1 st 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) 127

128 Residential Rate Options Basic rate E-1 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 128

129 E-6 Time Periods 129

130 Example of Billing: E1 Customer lives in San Francisco (territory T) and has gas heating Baseline Quantity (kwh): Summer per day Winter per day 30 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 $ = $28.76 Tier 2 101%-130% of Baseline: 74.7 x $ = $9.81 Tier 3 131%-200% of Baseline: 76.3 x $ = $18.87 Tier 4 201% - 300% of Baseline: 0 x $ Tier 5 Over 300% of Baseline: 0 x $ Total = $

131 Example of Billing: E6 Same customer and usage as E1 example: monthly baseline = 249 kwh E6 Customer s Net Usage: Peak -200 Partial Peak 100 Off Peak 500 = 400 kwh Net Peak: -200 T1 Baseline: (-200/400)x249= x $ = -$36.48 T2 101%-130% of Baseline: x $ = -$11.53 T3 131%-200% of Baseline: x $ = -$16.19 Partial Peak: 100 T1 Baseline: (100/400)x249= x $ = $8.99 T2 101%-130% of Baseline: x $ = $2.99 T3 131%-200% of Baseline: x $ = $5.26 Off Peak: 500 T1 Baseline: (500/400)x249= x $ = $26.32 T2 101%-130% of Baseline: x $ = $9.37 T3 131%-200% of Baseline: x $ = $19.67 Total = $

132 Commercial Rate Options A-1 Basic rate for small commercial Best for low usage, under 50,000 kwh/year A-6 Time of Use (TOU) rate for small commercial Best if majority of usage is at night and weekends E-19 Voluntary TOU rate for large commercial with maximum demand* up to 499 kw E-19 Mandatory TOU rate for large commercial with maximum demand* between kw If demand > 1000, must be E-20 A-10 Demand rate for medium commercial Best if usage expected is over 50,000 kwh/year E-20 Mandatory TOU rate for large commercial with maximum demand* over 1000 kw demand monthly *Demand is the maximum amount of electricity drawn within a 15 min interval 132
