SDG&E is requesting offers for the following resources:

  1. Energy Efficiency (EE)

  3. Renewables
  4. Combined Heat and Power (CHP)
  5. Energy Storage

The below diagram provides a high level overview of SDG&E’s procurement authorization for this RFO. 

High Level Overview of SDG&E's procurement authorization

As shown in the above diagram (from D.14-03-004, p. 98), SDG&E is authorized to procure up to 800MW of energy storage, up to 775MW of preferred resources (not including energy storage) or up to 600 MW from ‘any source’, such as conventional resources or some combination thereof totaling up to 800 MW. 

SDG&E has separately filed an application for Commission approval of a 600 MW bilateral contract with a conventional resource, the Carlsbad Energy Center (A.14-07-009). 

If approved, 600 MW of SDG&E’s need will be filled by this contract and SDG&E will be authorized to procure a minimum of 200 MW of preferred resources, including at least 25 MW of energy storage.  In this event, bidders will be notified that 600 MW of the need eligible under this RFO has been filled.

SDG&E is soliciting third party-owned, contracted resources for all of the product types listed above with the exception of energy storage.  For the energy storage product type, SDG&E is soliciting both third party owned, contracted resources and energy storage systems to be owned by SDG&E (more information on Utility owned storage can be found in the Energy Storage RFO document). 

SDG&E’s solicitation process is designed and intended to evaluate the different resource types (and ownership structures, in the case of energy storage) on an equivalent basis.  SDG&E will consider loading order ranking of the resource types as a qualitative factor.  

Limit on Number of Offers / Bids

Each Respondent is limited to six bids.  Bids may include multiple locations, hybrid technologies, or phased development as long as the package is priced as a single bid.   Variations in critical project details, like commercial operation date, contract term, energy deliveries, capacity, interconnection point, or operational constraints, must be submitted as separate bids.  For example, a project consisting of multiple 5 MW storage systems sited across San Diego to be installed in phases over the course of 2 years for one all inclusive price would be considered one bid.  However, a project consisting of one solar facility located at a specific substation with six different possible commercial operation dates would be considered 6 different bids. 

If the respondent has questions or concerns regarding bid limits, please contact SDG&E at:  [email protected]

Participation from Diverse Business Enterprises

SDG&E encourages Diverse Business Enterprises (“DBEs”), “Women-Owned Businesses” or “Minority-Owned Businesses” or “Disabled Veteran Business Enterprises” as defined in G.O. 156[1], to participate in this All Source RFO. 

Furthermore, SDG&E encourages developers to utilize DBEs during various stages of project development and construction. As a part of G.O. 156, SDG&E will require developers to identify and verify their DBE contractor/subcontractor spending if any.
