Feed-in Tariffs for Small Renewable Generation

AB 1969: RPS Tariff/Standard Contract for Water and Wastewater Facilities

Background

California Assembly Bill 1969, signed by Governor Arnold Schwarzenegger on September 29, 2006, requires electrical corporations to purchase electricity produced by a renewable generator owned and operated by Eligible Public Water Agencies or Wastewater Agencies with a total effective generation capacity of not more than 1.5 megawatts.  On July 26, 2007, the California Public Utilities Commission (CPUC) in Decision 07-07-027 adopted tariffs and standard contracts implementing AB 1969.

Program Summary

The program creates an opportunity for public water and wastewater customers only to sell electricity to SDG&E at a pre-determined price on a first come first served basis until SDG&E’s 20.055 MW of capacity allotment is filled.

Frequently Asked Questions – Water/Wastewater (WATER) and Customer Renewable Energy (CRE) Programs

Can you describe these programs?

The Water Program was established by the California State Legislature to create an opportunity for public water and wastewater customers to sell electricity to SDG&E at a pre-determined price, on a first-come first-served basis, until SDG&E’s 20.055 MW of capacity allotment is filled.

On September 22, 2008, the California Public Utilities Commission (“CPUC”) adopted a decision extending this opportunity under the same terms and conditions to all other non-water/non-wastewater SDG&E customers, who have an eligible renewable generator.  Under this Customer Renewable Energy (CRE) Program, these non-water/non-wastewater SDG&E customers will be treated exactly the same as the public water and wastewater customers, in that they will be paid a pre-determined price, on a first-come first-served basis.  SDG&E will continue to contract with these non-water/non-wastewater customers until an additional and separate 20.055 MW cap is reached.  

Why is SDG&E offering these programs to customers?

The California legislature passed Assembly Bill (“AB”) 1969 in 2006.  AB 1969 required the development of a renewable generation tariff and standard contract applicable to water and wastewater agencies that install a renewable generator.  This opportunity was expanded to include all other SDG&E customers, who install a renewable generator with a capacity not to exceed 1.5 MWs.

Who is eligible to participate in these programs?

Any SDG&E customer that currently has or is planning on installing an eligible renewable generator may participate in these programs.  However, any customer that is participating in any other SDG&E interruptible, Self Generation Incentive Program (“SGIP”) California Solar Initiative (“CSI”) or receiving service under SDG&E’s NEM tariff may not participate in these programs.

What are the requirements to participate in these programs?

Customers must have or plan to install an eligible renewable generating facility that meets the following criteria:

  1. Has an effective capacity of not more than 1.5 MW
  2. Is located on property owned or under the control of the eligible customer
  3. Is interconnected and operates in parallel with SDG&E’s electric transmission and distribution grid
  4. Is sized to offset part or all of the electricity demand of the customer’s load
  5. Is strategically located and interconnected to the electric transmission system in a manner that optimizes the deliverability of electricity at the facility to load centers
  6. Is an eligible renewable energy resource, as defined in PU Code § 399.12
  7. Meets the requirements for a Small Power Producer Qualifying Facility (“QF”) pursuant to the regulations of the Federal Energy Regulatory Commission (“FERC”)

What needs to be done to become a QF?

Guidance on obtaining QF status can be located at the following FERC address.

What is the definition of an “eligible renewable energy resource”?

Public Utilities Code § 399.12 defines an “eligible renewable resource” as a facility that meets the definition of Section 25741 of the Public Resources Code.  Section 25741 (b)(1) states that: “the facility uses biomass, solar thermal, photovoltaic, wind, geothermal, fuel cells using renewable fuels, small hydroelectric generation of 30 megawatts or less, digester gas, municipal solid waste conversion, landfill gas, ocean wave, ocean thermal, or tidal current, and any additions or enhancements to the facility using that technology.”

What tariffs and/or other documents apply to these programs?

There are two tariffs that are applicable, each with its own power purchase agreement (“PPA”).  Schedule WATER and its corresponding PPA are applicable to public water and wastewater customers.  Schedule CRE and its corresponding PPA are applicable to all other SDG&E customers.

What are some of the key terms of the WATER and CRE Agreements (e.g. price paid, term, etc.)?

Payment price

The rate paid to customers is established by the CPUC.  The price is referred to as the Market Price Referent (“MPR”) and is updated annually by the CPUC.  Download a copy of the CPUC’s resolution adopting the current MPR values.  The actual rate is determined at the time the Generating Facility achieves commercial operation and remains in effect (i.e., does not escalate over time) for the life of the agreement.  A copy of the current MPR pricing listed in both PPAs.

Delivery Periods

For the purpose of calculating monthly payments, the amount measured will be time-differentiated according to the time period and season (“Time of Delivery Periods”) and the pricing shall be weighted by the factors set forth below.

The monthly payment shall equal the sum of the monthly TOD Period payments for all TOD Periods in the month.  Each monthly TOD Period payment shall be calculated pursuant to the following formula, where “n” is the TOD Period being calculated:

TOD PERIODn PAYMENT = A x B x C

Where:
A = Levelized MPR Price in $/kWh.
B = TOD Factor, set forth above, for the TOD Period being calculated.
C = The sum of energy measured in accordance with Option A (full buy/sell) or Option B (sale of excess) in all hours for the TOD Period being calculated in kWh.

 

Agreement terms

Customers can select a term of 10, 15 or 20 years.

Selling options

  • Option A (full buy/sell) – SDG&E will purchase every kilowatt-hour produced by the Generating Facility.  All host customer electrical load served by the Generating Facility and purchased by SDG&E will then be billed to the host customer at SDG&E’s standard tariff rates.
  • Option B (sale of excess) – Only the excess electricity produced and exported to SDG&E’s electric system will be purchased at the MPR rate. Please see tariff/standard contract for the current MPR rate.

Who owns the Renewable Energy Credits (“RECs”)?

  • Under Option A (full buy/sell), SDG&E purchases all of the generated power and owns the corresponding RECs.
  • Under Option B (sale of excess)
    1. The customer owns any RECs associated with the power the customer generates and uses on site to serve its own load
    2. SDG&E owns any RECs associated with  power in excess of the on-site load that is exported to the grid and purchased by SDG&E.

SDG&E will count any of the RECs purchased under either Option A or Option B toward fulfilling its goal under California’s Renewables Portfolio Standard.

Who pays for the costs related to interconnecting the Generating Facility to SDG&E?

The customer is responsible for requesting interconnection to SDG&E and providing the required fees and equipment additions needed to insure a safe and reliable interconnection.
