Amendment 39

Allowing Vehicle to Grid Technology

Messrs. Crighton and Keenan move that the proposed new text be amended in section 79, by striking out, in line 2666, the figure "9" and inserting in place thereof the following figure:- 10; and

in section 79 by adding the following section:-

Section 161. (a) For the purposes of this section, the following words shall, unless the context clearly requires otherwise, have the following meanings:

“Bidirectional electric vehicle”, an electric vehicle that is capable of both receiving and discharging electricity.

“Electric vehicle supply equipment” or “EVSE”, a device or system designed and used specifically to transfer electrical energy between an electric vehicle and the electric grid.

“V2G AC”, a bidirectional electric vehicle that discharges AC power from a vehicle by converting DC energy from the battery to AC power via an onboard inverter.

“V2G DC”, a bidirectional electric vehicle that discharges DC power from a vehicle which is then converted to AC power via an offboard inverter.

“V2G system interconnection”, a process by which a distribution company allows a V2G system to interconnect to the electric distribution grid for the purpose of operating in parallel with the grid.

“Vehicle-to-grid system” or “V2G system”, a combination of hardware and software in or around the EVSE and bidirectional electric vehicle that forms a distributed energy resource for the purposes of communication with and programmed flow of energy into an out-of-the-vehicle battery in support of electrical loads or systems offboard the electric vehicle, including the electric grid.

(b) Each distribution company shall offer a comprehensive process for the interconnection of a V2G system at residential buildings which shall:

(i) provide a pathway for interconnection for V2G systems supporting V2G AC and V2G DC electric vehicles;

(ii) utilize standards adopted by a nationally recognized testing laboratory certified by the United States Occupational Safety and Health Administration, including, but not limited to, the standards developed by Underwriters Laboratories, Inc., UL 1741 CRD for Grid Support Distributed Energy Resource Systems and UL 1741 SC;

(iii) be as consistent as practicable across all distribution company service territories;

(iv) not require an interconnection application or interconnection agreement for bidirectional electric vehicles and associated electric vehicle supply equipment that are not configured to operate in parallel with the grid; and

(v) utilize best practices from comprehensive V2G system interconnection processes adopted by other states and utilities, as practicable.

(c) The department shall issue guidance to the distribution companies as needed regarding the development of the V2G system interconnection process.

(d) The distribution companies shall file proposed tariff provisions or tariff revisions and any other documents necessary to implement the required V2G system interconnection process with the department.

(e) Not later than 120 days after the effective date of this act, the department of public utilities shall issue guidance to the distribution companies as needed regarding the development of the V2G system interconnection process pursuant to subsection (c) of section 161 of chapter 164 of the General Laws

(f) Not later than 180 days after the effective date of this act, distribution companies shall file with the department of public utilities proposed tariff provisions or tariff revisions and any other documents necessary to implement the V2G interconnection process, pursuant to subsection (d) of said section 161 of said chapter 164

(g) Not later than 1 year after the effective date of this act, the department of public utilities shall approve, deny or modify and approve the proposed tariff provisions or tariff revisions submitted by the distribution companies pursuant to subsection (d) of said section 161 of said chapter 164. A V2G system proposal filed pursuant to said subsection (d) shall be deemed approved if the department does not approve, deny or modify and approve such proposed tariff provisions or tariff revisions not later than 1 year after the effective date of this act.
