Thermal Program
Commercial/Multi-family updates
       Purpose of this webinar

    •Provide information on the recently launched
    Commercial/Multi-family CSI-Thermal Program
    •Supplement workshop for participants that have
    already attended the CSI-Thermal Workshop
    •Will not cover single-family residential program
    information
    •Will not be a substitute for the CSI-Thermal
    Workshop

    CSI THERMAL PROGRAM
    ELIGIBILITY REQUIREMENTS




3
Customer Class

 • Customer Class and Incentive Rate determined by
   Utility Rate Schedule
     • Residential Rate = Single-family residential
     • Commercial Rate = Commercial/Multi-family
     • Master Meter Rate = Commercial/Multi-family




 4
Customer Eligibility
    Host Customer: The utility customer of record
    at the location where the SWH system will be
    located.
      • Natural Gas Water Heating Customers of PG&E,
        SDG&E, SCG

      • Electric Water Heating Customers of PG&E,
        SDG&E, SCE
      *Propane Water Heating Customers are not
          eligible for a CSI-Thermal incentive
5
End Use Eligibility: Multi-family/Commercial

Multi-family/commercial applications, SWH applications must
directly consume the solar heated potable water, as opposed to
using the solar heated water as a medium to carry heat for some
other end use. In multi-family/commercial applications, DHW and
commercial end uses are eligible.

•Combination Systems: Applicants must provide documentation
proving DHW energy savings for combination systems. Incentives
will only apply to the DHW portion of the load.

         Site Definition

For multi-family/commercial projects, site is defined as:
• The Host Customer’s premises, consisting of all the real property and apparatus
    employed in a single enterprise on an integral parcel of land undivided, excepting in
    the case of industrial, agricultural, oil field, resort enterprises, and public or quasi-
    public institutions divided by a dedicated street, highway or other public
    thoroughfare or railway.

•    Automobile parking lots constituting a part of and adjacent to a single enterprise may
     be separated by an alley from the remainder of the premises served.

•    Separate business enterprises or homes on a single parcel of land undivided by a
     highway, public road, and thoroughfare or railroad would be considered for purposes
     of CSI-Thermal Program as separate sites.

Note: The total incentives for multiple systems on one multi-family/commercial site
   cannot exceed the incentive cap per customer class ($500,00 for Natural Gas,
   $250,000 for Electric).

        tank(s) and a back-up water heater, required equipment consists of a BTU meter, i.e.,
        a flow meter on the cold water supply line, an appropriately located temperature
        sensor pair, and a calculator.

      • One Tank Systems: For one-tank systems in which the storage tank is heated by both
        thermal solar and an auxiliary heat source, required equipment consists of a BTU
        meter, i.e., a flow meter on the cold water supply line, an appropriately placed
        temperature sensor pair, and a meter that measures the gas or electric contribution
        from the back-up water heater or boiler.

Equipment Accuracy Standard: Metering equipment must have a maximum
   permissible error +/- 2% for the flow meter throughout the meter’s specified
   flow range and +/- 0.25 °F for the temperature sensors.

Equipment Location: Metering equipment must be installed on the potable water
   side of the SWH system.
 19
 Metering: CPM
     Customer Performance Monitoring (CPM)

     • Required for systems >30kWth

     • Contractor is responsible for maintenance of meter and
       communication system

     • CPM providers will provide SWH system performance,
       monitoring, and reporting services to the System Owner
        • The information provided allows the System Owner to maintain
          and evaluate system performance.


20
   Metering Equipment: CPM
Customer Performance Monitoring (30 kWth<system ≤ 250 kWth)

• Required Equipment: Required equipment consists of a BTU meter, i.e., a flow
  meter, a temperature sensor pair, and a calculator.

  permissible error +/- 2% for the flow meter at full flow and +/- 0.25° F for the
  temperature sensors.

• Equipment Location: Metering equipment may be installed either on the
  collector loop or potable water side of the SWH system.

• Communication Requirements: For a period of five years from start of
  operation, System Owner must have the means to determine if the system is
  operating. At a minimum, the CPM equipment must provide the quantity of
  solar energy delivered to the System Owner.

     PROCESS




28
Commercial/Multi-family ≤ 250kWth

      Lump Sum Payment
      • One-time payment

      • Based on estimated therm of kWh savings
        provided by the OG-100 Calculator

      • Paid after project is completed, approved,
        and inspected (if applicable)
 29
Commercial/Multi-family > 250kWth

 70/30 True-Up Payment
 • Payment made in two parts:

      1) Commercial/Multi-family calculator estimates therm or
         kWh savings. PA pays 70 percent of that incentive after
         Incentive Claim and Inspection (if applicable) are approved

      2) System is then metered/monitored for 12 consecutive
         months. PA pays the true-up incentive amount by
         subtracting the initial 70 percent incentive payment from
         the final metered incentive amount.

      *Program will pay no more than 110% of estimated incentive
 30
       70/30 True-up Example
 Actual energy savings less than expected
 • Estimated energy savings is 12,000 therms per year which equates to a
   $153,840 incentive ($12.82 x 12,000)

 • PA pays 70 percent of this amount, or $107,688 ($153,840x.70), once the
   project is completed, approved, and inspected (if applicable)

 • Customer’s energy savings is then measured for twelve months and is
   found to be 10,500 therms

 • Based on the actual metered energy delivered from the SWH system, the
   total incentive amount is $134,610 (10,500 therms x $12.82 per therm)

 • PA then pays the true-up incentive payment of $26,922 ($134,610 -
   $107,688 upfront lump sum incentive)

        System Sizing: MF/Commercial
 •   Multi-family (MF)/Commercial Projects – Annual average GPD is estimated based on
     the Maximum GPD Guideline Table (Appendix D).
 •   SWH systems for the building types listed in Maximum GPD Guideline Table must be
     sized using the GPD value in this table for the appropriate building type. The GPD
     values in the table are maximum values. Systems may be sized using a lesser GPD
     assumption.
 •   Building types not listed in the Maximum GPD Guideline Table must do one of the
     following:
       Meter actual hot water consumption using an in-line water flow meter with accumulator for a
        minimum of 60 calendar days and adjust for seasonal variability. Hot water consumption calculation
        must be stamped by a P.E.
       Meter natural gas or electric consumption at the water heater for a minimum of 60 days and adjust for
        seasonal variability. Water heater gas or electric meter consumption calculation must be stamped by a
        P.E.

 •   Fluid collector square footage cannot exceed 1.25 times the GPD, or 1.85 times for
     air collectors.
 •   Systems with two or more tanks must have a minimum of one gallon of storage per
     square foot of collector. One-tank systems must have a minimum of 1.25 gallons of
50   storage per square foot of collector.
       System Sizing: MF/Commercial
