Current through Register 2024 Notice Reg. No. 38, September 20, 2024
(a) Marginal Cost-Based Rates. This standard
requires that each Large IOU develop marginal cost-based rates structured
according to the requirements of this article and that the Large IOU submit
such rates to its rate-approving body for approval.
(1) Total marginal cost shall be calculated
as the sum of the marginal energy cost, the marginal capacity cost (generation,
transmission, and distribution), and any other appropriate time and location
dependent marginal costs, including the locational marginal cost of associated
greenhouse gas emissions, on a time interval of no more than one hour. Energy
cost computations shall reflect locational marginal cost pricing as determined
by the associated balancing authority, such as the California Independent
System Operator, the Balancing Authority of Northern California, or other
balancing authority. Marginal capacity cost computations shall reflect the
variations in the probability and value of system reliability of each component
(generation, transmission, and distribution).
(2) Within twenty-one (21) months of April 1,
2023, each Large IOU shall apply to its rate-approving body for approval of at
least one marginal cost-based rate, in accordance with 1623(a)(1), for each
customer class.
(3) Large IOUs
shall provide the Commission with informational copies of tariff applications
when they are submitted to their rate-approving bodies.
(b) Publication of Machine-Readable
Electricity Rates. No later than three (3) months after April 1, 2023, each
Large IOU shall upload its existing time-dependent rates applicable to its
customers to the Commission's Market Informed Demand Automation Server (MIDAS)
database. Each Large IOU shall upload all time-dependent rates, including those
approved after April 1, 2023, to MIDAS prior to the effective date of the
time-dependent rates each time a time-dependent rate is approved by the
rate-approving body and each time a time-dependent rate changes.
The time-dependent rates uploaded to the MIDAS database
shall include all applicable time-dependent cost components, including, but not
limited to, generation, distribution, and transmission. The Commission
maintains public access to the MIDAS-database through an Application
Programming Interface (API) that, provided a Rate Identification Number (RIN),
returns information sufficient to enable automated response to marginal grid
signals including price, emergency events, and greenhouse gas
emissions.
(c) Support
Customer Ability to Link Devices to Electricity Rates.
(1) Third-party Access. The Large IOUs, Large
POUs and Large CCAs shall develop a single statewide standard tool for
authorized rate data access by third parties that is compatible with each of
those entities' systems. The tool shall:
(A)
Provide the RIN(s) applicable to the customer's premise(s) to third parties
authorized and selected by the customer;
(B) Provide any RINs, to which the customer
is eligible to be switched, to third parties authorized and selected by the
customer;
(C) Provide estimated
average or annual bill amount(s) based on the customer's current rate and any
other eligible rate(s) if the Large IOU, Large POU or Large CCA has an existing
rate calculation tool and the customer is eligible for multiple
rates;
(D) Enable the authorized
third party to, upon the direction and consent of the customer, modify the
customer's applicable rate to be reflected in the next billing cycle according
to the Large IOU's, Large POU's or Large CCA's standard procedures;
(E) Incorporate reasonable and applicable
cybersecurity measures;
(F)
Minimize enrollment barriers; and
(G) Be accessible in a digital,
machine-readable format according to best practices and
standards.
(2) The Large
IOUs, Large POUs and Large CCAs shall submit the single statewide standard tool
developed pursuant to Section
1623(c)(1) to the
Commission for approval at a Business Meeting.
(A) The tool must be submitted within
eighteen (18) months of April 1, 2023.
(B) The Executive Director may extend this
deadline upon a showing of good cause.
(C) The Large IOUs, Large POUs and Large CCAs
shall describe a single set of terms and conditions they intend to require of
third parties using the single statewide standard tool.
(3) Upon Commission approval the Large IOUs,
Large POUs and Large CCAs shall implement and maintain the tool developed in
Section 1623(c)(1).
(4) Customer Access. No later than one (1)
year after April 1, 2023, each Large IOU, Large POU and Large CCA shall provide
customers access to their RIN(s) on customer billing statements and online
accounts using both text and quick response (QR) or similar machine-readable
digital code.
(5) Any changes to
the single statewide standard tool, including changes to the terms and
conditions, shall be submitted to the Executive Director for approval. The
Executive Director shall submit any substantive changes to the Commission for
approval at a Business Meeting.
(d) Public Programs. Large IOUs shall
encourage mass-market automation of load management through information and
programs.
(1) No later than eighteen (18)
months after April 1, 2023, each Large IOU shall submit to the Executive
Director a list of load flexibility programs deemed cost-effective by the Large
IOU. The portfolio of identified programs shall provide any customer with at
least one option for automating response to MIDAS signals indicating marginal
cost-based rates, marginal prices, hourly or sub-hourly marginal greenhouse gas
emissions, or other Commission-approved marginal signal(s) that enable
automated end-use response.
(2)
Within forty-five (45) months of April 1, 2023, each Large IOU shall offer to
each of its electricity customers voluntary participation in a marginal
cost-based rate developed according to Section
1623(a) if such
rate is approved by the Large IOU's rate-approving body, or a cost-effective
program identified according to Section
1623(d)(1) if
such rate is not yet approved by the Large IOU's rate-approving body.
(3) Each Large IOU shall conduct a public
information program to inform and educate the affected customers why marginal
cost-based rates and automation are needed, how they will be used, and how
these rates can save the customer money.
