Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process.
Recent laws may not yet be included in the ILCS database, but they are found on this site as
Public
Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the
Guide.
Because the statute database is maintained primarily for legislative drafting purposes,
statutory changes are sometimes included in the statute database before they take effect.
If the source note at the end of a Section of the statutes includes a Public Act that has
not yet taken effect, the version of the law that is currently in effect may have already
been removed from the database and you should refer to that Public Act to see the changes
made to the current law.
(220 ILCS 5/16-135) Sec. 16-135. Energy Storage Program. (a) The Illinois General Assembly hereby finds and declares that: (1) Energy storage systems provide opportunities |
|
(A) reduce costs to ratepayers directly or
|
| indirectly by avoiding or deferring the need for investment in new generation and for upgrades to systems for the transmission and distribution of electricity;
|
|
(B) reduce the use of fossil fuels for meeting
|
| demand during peak load periods;
|
|
(C) provide ancillary services such as
|
| frequency response, load following, and voltage support;
|
|
(D) assist electric utilities with integrating
|
| sources of renewable energy into the grid for the transmission and distribution of electricity, and with maintaining grid stability;
|
|
(E) support diversification of energy resources;
(F) enhance the resilience and reliability of
|
|
(G) reduce greenhouse gas emissions and other
|
| air pollutants resulting from power generation, thereby minimizing public health impacts that result from power generation.
|
|
(2) There are significant barriers to obtaining the
|
| benefits of energy storage systems, including inadequate valuation of the services that energy storage can provide to the grid and the public.
|
|
(3) It is in the public interest to:
(A) develop a robust competitive market for
|
| existing and new providers of energy storage systems in order to leverage Illinois' position as a leader in advanced energy and to capture the potential for economic development;
|
|
(B) implement targets and programs to achieve
|
| deployment of energy storage systems; and
|
|
(C) modernize distributed energy resource
|
| programs and interconnection standards to lower costs and efficiently deploy energy storage systems in order to increase economic development and job creation within the state's clean energy economy.
|
|
(b) In this Section:
"Energy storage peak standard" means a percentage of annual retail electricity sales during peak hours that an electric utility must derive from electricity discharged from eligible energy storage systems.
"Deployment" means the installation of energy storage systems through a variety of mechanisms, including utility procurement, customer installation, or other processes.
"Electric utility" has the same meaning as provided in Section 16-102 of this Act.
"Energy storage system" means a technology that is capable of absorbing zero-carbon energy, storing it for a period of time, and redelivering that energy after it has been stored in order to provide direct or indirect benefits to the broader electricity system. The term includes, but is not limited to, electrochemical, thermal, and electromechanical technologies.
"Nonwires alternatives solicitation" means a utility solicitation for third-party-owned or utility-owned distributed energy resources that uses nontraditional solutions to defer or replace planned investment on the distribution or transmission system.
"Total peak demand" means the highest hourly electricity demand for an electric utility in a given year, measured in megawatts, from all of the electric utility's customers of distribution service.
(c) The Commission, in consultation with the Illinois Power Agency, shall initiate a proceeding to examine specific programs, mechanisms, and policies that could support the deployment of energy storage systems. The Illinois Commerce Commission shall engage a broad group of Illinois stakeholders, including electric utilities, the energy storage industry, the renewable energy industry, and others to inform the proceeding. The proceeding must, at minimum:
(1) develop a framework to identify and measure the
|
| potential costs, benefits, that deployment of energy storage could produce, as well as barriers to realizing such benefits, including, but not limited to:
|
|
(A) avoided cost and deferred investments in
|
| generation, transmission, and distribution facilities;
|
|
(B) reduced ancillary services costs;
(C) reduced transmission and distribution
|
|
(D) lower peak power costs and reduced capacity
|
|
(E) reduced costs for emergency power supplies
|
|
(F) reduced curtailment of renewable energy
|
|
(G) reduced greenhouse gas emissions and other
|
|
(H) increased grid hosting capacity of
|
| renewable energy generators that produce energy on an intermittent basis;
|
|
(I) increased reliability and resilience of the
|
|
(J) reduced line losses;
(K) increased resource diversification;
(L) increased economic development;
(2) analyze and estimate:
(A) the impact on the system's ability to
|
| integrate renewable resources;
|
|
(B) the benefits of addition of storage at
|
| specific locations, such as at existing peaking units or locations on the grid close to large load centers;
|
|
(C) the impact on grid reliability and power
|
|
(D) the effect on retail electric rates and
|
| supply rates over the useful life of a given energy storage system; and
|
|
(3) evaluate and identify cost-effective policies
|
| and programs to support the deployment of energy storage systems, including, but not limited to:
|
|
(A) incentive programs;
(B) energy storage peak standards;
(C) nonwires alternative solicitation;
(D) peak demand reduction programs for
|
| behind-the-meter storage for all customer classes;
|
|
(E) value of distributed energy resources
|
|
(F) tax incentives;
(G) time-varying rates;
(H) updating of interconnection processes and
|
|
(I) procurement by the Illinois Power Agency of
|
| energy storage resources.
|
|
(d) The Commission shall, no later than May 31, 2022, submit to the General Assembly and the Governor any recommendations for additional legislative, regulatory, or executive actions based on the findings of the proceeding.
(e) At the conclusion of the proceeding required under subsection (c), the Commission shall consider and recommend to the Governor and General Assembly energy storage deployment targets, if any, for each electric utility that serves more than 200,000 customers to be achieved by December 31, 2032, including recommended interim targets.
(f) In setting recommendations for energy storage deployment targets, the Commission shall:
(1) take into account the costs and benefits of
|
| procuring energy storage according to the framework developed in the proceeding under subsection (c);
|
|
(2) consider establishing specific subcategories of
|
| deployment of systems by point of interconnection or application.
