A N A C T | |
RELATING TO PUBLIC UTILITIES AND CARRIERS -- ENERGY STORAGE SYSTEMS | |
ACT | |
| |
Introduced By: Senators Euer, Sosnowski, DiMario, and Zurier | |
Date Introduced: March 01, 2024 | |
Referred To: Senate Commerce | |
It is enacted by the General Assembly as follows: | |
1 | SECTION 1. Legislative findings and purpose. |
2 | The general assembly hereby finds that: |
3 | (1) An energy storage system connected to the electric power system could alleviate time |
4 | and location-based constraints on the distribution and bulk power systems, including physical, |
5 | economic, and environmental constraints, and result in lower costs to the general body of ratepayers |
6 | if located in the right place and operated at the right time. |
7 | (2) Currently, Rhode Island does not have an interconnection tariff that recognizes the |
8 | potential flexibility and dispatchability of energy storage systems. |
9 | (3) The public utilities commission should advance frameworks that would promote |
10 | advancement of grid connected energy storage systems when those systems can provide net value |
11 | to the general body of ratepayers. |
12 | (4) In order to secure a long-term, stable, and affordable supply of energy storage systems, |
13 | it is essential that Rhode Island begin procuring and deploying energy storage systems as an |
14 | alternative to costly and redundant utility distribution infrastructure. |
15 | SECTION 2. Title 39 of the General Laws entitled "PUBLIC UTILITIES AND |
16 | CARRIERS" is hereby amended by adding thereto the following chapter: |
17 | CHAPTER 33 |
18 | ENERGY STORAGE SYSTEMS ACT |
| |
1 | 39-33-1. Definitions. |
2 | As used in this chapter: |
3 | (1) "Commission" means the public utilities commission. |
4 | (2) "Energy storage system" means any technology capable of converting electrical energy |
5 | to some form of stored energy for reconversion to electrical energy at a later time. |
6 | (3) "Long-duration energy storage system" means energy storage systems that are capable |
7 | of permanently displacing fossil fuel energy systems designed to store energy or necessary for |
8 | balancing intermittent renewable energy resources. |
9 | 39-33-2. Storage tariff. |
10 | No later than September 1, 2024, the public utilities commission shall engage stakeholders |
11 | to adopt a framework for an energy storage system tariff for energy storage systems connected to |
12 | the electric distribution system. |
13 | (1) The tariff framework should, at a minimum, address the ability of energy storage |
14 | systems to charge from and discharge to the electric distribution system. |
15 | (2) The commission shall set a schedule that is designed to result in a model tariff no later |
16 | than May 1, 2025, consistent with the tariff framework. |
17 | (3) Following that date, if the commission finds that the energy storage system tariff can |
18 | be implemented without inequitable cross subsidization between customers, each electric |
19 | distribution company as defined in § 39-1-2 that has greater than one hundred thousand (100,000) |
20 | customers shall file the model tariff for review and approval by the public utilities commission in |
21 | a contested proceeding. Otherwise, the model tariff shall be included as part of the electric |
22 | distribution company’s next general rate filing. |
23 | 39-33-3. Interconnection. |
24 | (a) No later than September 1, 2024, the commission shall commence a process, which |
25 | includes stakeholder engagement, to adopt a framework for an interconnection tariff for energy |
26 | storage systems connected to the electric distribution system that recognizes the flexible operating |
27 | characteristics of energy storage systems. |
28 | (b) Following the public utilities commission’s adoption of a framework, which shall be |
29 | completed no later than May 1, 2025, each electric distribution company as defined in § 39-1-2 that |
30 | has greater than one hundred thousand (100,000) customers shall file a proposed energy storage |
31 | system interconnection tariff for review and approval in a contested proceeding. |
32 | 39-33-4. Periodic storage assessment and procurement. |
33 | (a) Not less than every three (3) years, the commission shall conduct a market survey to |
34 | assess the capabilities of storage technologies and whether those capabilities have the potential to |
| LC005005/SUB A/2 - Page 2 of 5 |
1 | meet the needs of, or provide net value to, the distribution system or the bulk power system. |
2 | (1) As part of its review, the commission shall consider time and location-based constraints |
3 | on the distribution and bulk power systems, including physical, economic, and environmental |
4 | constraints that increase costs to the general body of ratepayers. |
5 | (2) Transmission level storage, at a minimum, shall include long duration energy storage |
6 | systems and short duration energy storage systems that have peaking capabilities, but may include |
7 | other applications. |
8 | (b) upon a finding by the commission that storage may meet distribution system or bulk |
9 | power system needs, or provide net value to the general body of ratepayers, the commission shall |
10 | direct the electric distribution company with more than one hundred thousand (100,000) customers |
11 | to conduct a procurement of transmission level or distribution level storage consistent with |
12 | subsection (c) of this section. This review shall also consider whether any changes need to be made |
13 | to previously approved storage procurement methods to meet the targets and may be conducted as |
14 | part of the review of system reliability and procurement in § 39-1-27.7(b). The commission’s |
15 | findings about appropriate targets and procurement shall be consistent with its least cost |
16 | procurement standards and that the approved procurement is cost effective, less than the cost of |
17 | available supply, reliable, prudent and environmentally responsible. |
18 | (c) The electric distribution company shall issue and, subject to review and approval of the |
19 | commission, select a reasonable, open, and competitive method of soliciting proposals from third |
20 | parties for one or more services from energy storage projects connected to the transmission or |
21 | distribution system in front of the meter, including, but not limited to, long-duration energy storage |
22 | projects, that would achieve the goals in chapter 33 of title 39. |
23 | 39-33-5. Administrative expense. |
24 | The commission is authorized to hire one or more consultants to assist with each task set |
25 | forth in this chapter and may assess its actual costs to each electric distribution company as defined |
26 | in § 39-1-2 that has greater than one hundred thousand (100,000) customers in a manner to be |
27 | determined by the commission. |
28 | SECTION 3. Section 39-26.1-4 of the General Laws in Chapter 39-26.1 entitled "Long- |
29 | Term Contracting Standard for Renewable Energy" is hereby amended to read as follows: |

31 | In order to achieve the purposes of this chapter, electric distribution companies shall be |
32 | entitled to financial remuneration and incentives for long-term contracts for newly developed |
33 | renewable energy resources, which are over and above the base rate revenue requirement |
34 | established in its cost of service for distribution ratemaking. Such remuneration and incentives shall |
| LC005005/SUB A/2 - Page 3 of 5 |
1 | compensate the electric distribution company for accepting the financial obligation of the long- |
2 | term contracts. The financial remuneration and incentives described in this section shall apply only |
3 | to long-term contracts for newly developed renewable energy resources. For long-term contracts |
4 | approved pursuant to this chapter before January 1, 2022, the financial remuneration and incentives |
5 | shall be in the form of annual compensation, equal to two and three quarters percent (2.75%) of the |
6 | actual annual payments made under the contracts for those projects that are commercially |
7 | operating, unless determined otherwise by the commission at the time of approval. For long-term |
8 | contracts approved pursuant to this chapter on or after January 1, 2022, including contracts above |
9 | the minimum long-term contract capacity, the financial remuneration and incentives shall be in the |
10 | form of annual compensation up to one percent (1.0%) of the actual annual payments made under |
11 | the contracts through December 31, 2026, for those projects that are commercially operating. For |
12 | all long-term contracts approved pursuant to this chapter on or after January 1, 2027, financial |
13 | remuneration and incentives shall not be applied, unless otherwise granted by the commission. For |
14 | any calendar year in which the electric distribution company’s actual return on equity exceeds the |
