What is ISO 15118?

ISO 15118 defines the “vehicle-to-grid” communication interface. As the first and only standard to integrate electric vehicles into the power grid, ISO 15118 makes it possible to identify and authenticate a vehicle, coordinate the charging process, handle the billing, and support additional services such as remote diagnostics, navigation system updates and entertainment.

What is Vehicle-Grid Integration (VGI)?

Vehicle-grid integration encompasses the ways EVs can manage charging or support two-way interaction between vehicles and the grid. Managed charging refers to the technical capability to modulate the electric charging of the vehicle through delay, throttling to draw more or less electricity, or switching load on or off. Two-way interaction refers to the controlled absorption and discharge of power between the grid and a vehicle battery, or a building and a vehicle battery.

VGI is enabled through technology and products that provide reliable vehicle charging services to EV owners. These products potentially additional revenue opportunities while reducing risks and creating cost savings opportunities for grid operators. VGI tools might include technologies like inverters, controls or chargers, or programs and products, such as time of use tariffs or bundled charging packages.

Charge Ready Program - SCE

Charge Ready Program – SCE region

To attain California’s zero emission vision, SoCal Edison (SCE) has announced their Charge Ready Program.

Four business types qualify for the program;

  • workplace,
  • multi-unit dwellings
  • destination centers and
  • Fleet operators.

How to be elegible;

  • Vehicles must be parked for at least 4 hours,
  • Deployment of a minimum of 10 charging stations per site
    • 5 for disadvantaged communities*.
  • You may select either a Level 1 or Level 2 charging station from an approved vendor.
  • You must own and operate the qualified charging station for at least 10 years and allow collection of the usage data on any Level 2 charging station.

What does it imply;

  • Your new charging station will be installed on a new, dedicated circuit with its own panel, meter and service separate from your current system.
  • The cost of the electric infrastructure and the installation of your new charging station are covered by the Charge Ready Program.
  • There is also a rebate on the EV charging stations.
  • Approved customers in:
    • disadvantaged communities will receive a rebate of 100%,
    • Multi-unit customers will receive 50%
    • Other customers will receive 25% of the base cost.

Power your drive program SDG&E

Power Your Drive – SDG&E

Power Your Drive is an exciting new pilot program that authorizes SDG&E® to install 3,500 electric vehicle charging stations across its service area

Four business types qualify for the program;

  • Apartments
  • Condos
  • Businesses
  • Fleet owners and
  • Disadvantaged communities.

How to be elegible;

  • Due to the limited number of sites and high demand for participation, sites will be prioritized by those that meet the following qualifications;
    • Apartments & condos need to dedicate a minimum of 5 parking spaces for EV charging stations
    • Business owners and fleets need to dedicate a minimum of 10 parking spaces for EV charging stations.
  • There are six easy steps to qualify.
    1. First sign Up on the SDG&E Interest List then SDG&E will schedule a 20-minute call to tell you more about Power Your Drive.
    2. You then submit your application.
    3. SDG&E will do a site site assesment,
    4. Assess your project and confirms the charging station location.
    5. The site host then selects a qualified EV chargers vendor
    6. SDG&E designs your site, installs the chargers and provides EV driver sign-up instructions.

What does it imply;

  • The chargers will be owned, operated and maintained by SDG&E at no cost to the site host and includes, all operational and maintenance costs, driver support and billing.
  • All charging equipment will be served from a separate SDG&E service and metered separately from the site host’s electric service and account.

Plug-In Electric Vehicle Sub-metering Pilot

Plug-In Electric Vehicle Sub-metering Pilot.

Residential and commercial Plug-In Electric Vehicle (PEV) customers of Pacific Gas & Electric (PG&E), Southern California Edison (SCE), and San Diego Gas & Electric (SDG&E), including Net Energy Metering customers, are eligible to participate in the Plug-In Electric Vehicle Sub Metering Pilot.

For residential and commercial customers to separately measure the electricity used to charge their electric vehicles (EV) through third-party or customer-owned submeters.

Who qualifies:

  • a customer must install an eligible submeter, which will only measure the electricity used to charge their electric vehicles.
  • The Submetering Phase 2 Pilot duration is 15.5 months starting January 16, 2017 and ending on April 30, 2018. The customer enrollment period is the first 3.5 months of the Pilot or until the maximum of 500 submeters is reached per Utility region.
  • Once enrolled in the Pilot, you’ll be eligible to participate for up to 12 consecutive billing cycles; however, you may choose to un-enroll at any time.

How to be eligible:

  • Select and engage a Submeter Meter Data Management Agent (MDMA) approved by the California Public Utilities Commission (CPUC).
  • Complete the Customer Enrollment Agreement with the help of your Submeter MDMA.
  • Have your Submeter MDMA submit the agreement to PG&E on your behalf.
  • PG&E will review and approve your enrollment if you meet all the Pilot requirements.
  • The list of available Submeter MDMAs will be provided when approved by the Energy Division of the CPUC.

What does this imply:

  • The pilot intends to improve customer choice and value by using energy meters specifically for PEV charging to help drivers save on fuel costs and avoid upgrading their electrical infrastructure.
  • This will allow customers of the utilities to have their electric vehicle charges billed at a different rate than their residences or businesses.
  • Encouraging night-time charging helps ensure that there is sufficient electrical grid capacity to meet the needs of all customers while minimizing cost and environmental impact.


Participants will be chosen on a first-come, first-served basis. Customers on a Net Energy Metering rate are eligible but will be limited to 100 of the participating submeters.

EV can raise your home or work bill to higher Tier 3 or 4 utilities rates, the sub metering program is designed to prevent that from happening.
