      Sec. 16-19. Amendment of rate schedule; investigations and findings by department; hearings; deferral of municipal rate increases; refunds; notice of application for rate amendment, interim rate amendment and reopening of rate proceeding. (a) No public service company may charge rates in excess of those previously 
approved by the authority or the Department of Public Utility Control except that any 
rate approved by the Public Utilities Commission or the authority shall be permitted 
until amended by the authority or the department, that rates not approved by the authority 
or the department may be charged pursuant to subsection (b) of this section, and that 
the hearing requirements with respect to adjustment clauses are as set forth in section 
16-19b. Each public service company shall file any proposed amendment of its existing 
rates with the department in such form and in accordance with such reasonable regulations as the department may prescribe. Each electric, electric distribution, gas or telephone company filing a proposed amendment shall also file with the department an 
estimate of the effects of the amendment, for various levels of consumption, on the 
household budgets of high and moderate income customers and customers having household incomes not more than one hundred fifty per cent of the federal poverty level. Each 
electric and electric distribution company shall also file such an estimate for space 
heating customers. Each water company, except a water company that provides water 
to its customers less than six consecutive months in a calendar year, filing a proposed 
amendment, shall also file with the department a plan for promoting water conservation 
by customers in such form and in accordance with a memorandum of understanding 
entered into by the department pursuant to section 4-67e. Each public service company 
shall notify each customer who would be affected by the proposed amendment, by mail, 
at least one week prior to the public hearing thereon, that an amendment has been or 
will be requested. Such notice shall also indicate (1) the Department of Public Utility 
Control telephone number for obtaining information concerning the schedule for public 
hearings on the proposed amendment and (2) whether the proposed amendment would, 
in the company's best estimate, increase any rate or charge by twenty per cent or more, 
and, if so, describe in general terms any such rate or charge and the amount of the 
proposed increase, provided no such company shall be required to provide more than 
one form of the notice to each class of its customers. In the case of a proposed amendment 
to the rates of any public service company, the department shall hold a public hearing 
thereon, except as permitted with respect to interim rate amendments by subsection (d) 
and subsection (g) of this section, and shall make such investigation of such proposed 
amendment of rates as is necessary to determine whether such rates conform to the 
principles and guidelines set forth in section 16-19e, or are unreasonably discriminatory 
or more or less than just, reasonable and adequate, or that the service furnished by 
such company is inadequate to or in excess of public necessity and convenience. The 
department, if in its opinion such action appears necessary or suitable in the public 
interest may, and, upon written petition or complaint of the state, under direction of the 
Governor, shall, make the aforesaid investigation of any such proposed amendment 
which does not involve an alteration in rates. If the department finds any proposed 
amendment of rates to not conform to the principles and guidelines set forth in section 
16-19e, or to be unreasonably discriminatory or more or less than just, reasonable and 
adequate to enable such company to provide properly for the public convenience, necessity and welfare, or the service to be inadequate or excessive, it shall determine and 
prescribe, as appropriate, an adequate service to be furnished or just and reasonable 
maximum rates and charges to be made by such company. In the case of a proposed 
amendment filed by an electric, electric distribution, gas or telephone company, the 
department shall also adjust the estimate filed under this subsection of the effects of the 
amendment on the household budgets of the company's customers, in accordance with 
the rates and charges approved by the department. The department shall issue a final 
decision on each rate filing within one hundred fifty days from the proposed effective 
date thereof, provided it may, before the end of such period and upon notifying all parties 
and intervenors to the proceedings, extend the period by thirty days.
      (b) If the department has not made its finding respecting an amendment of any rate 
within one hundred fifty days from the proposed effective date of such amendment 
thereof, or within one hundred eighty days if the department extends the period in accordance with the provisions of subsection (a) of this section, such amendment may become 
effective pending the department's finding with respect to such amendment upon the 
filing by the company with the department of assurance satisfactory to the department, 
which may include a bond with surety, of the company's ability and willingness to 
refund to its customers with interest such amounts as the company may collect from 
them in excess of the rates fixed by the department in its finding or fixed at the conclusion 
of any appeal taken as a result of a finding by the department.
      (c) Upon conclusion of its investigation of the reasonableness of any proposed increase of rates, the department shall order the company to refund to its customers with 
interest any amounts the company may have collected from them during the period that 
any amendment permitted by subsection (b) of this section was in force, which amounts 
the department may find to have been in excess of the rates fixed by the department in 
its finding or fixed at the conclusion of any appeal taken as a result of a finding by the 
department. Any such refund ordered by the department shall be paid by the company, 
under direction of the department, to its customers in such amounts as are determined 
by the department.
      (d) Nothing in this section shall be construed to prevent the department from approving an interim rate increase, if the department finds that such an interim rate increase 
is necessary to prevent substantial and material deterioration of the financial condition 
of a public service company, to prevent substantial deterioration of the adequacy and 
reliability of service to its customers or to conform to the applicable principles and 
guidelines set forth in section 16-19e, provided the department shall first hold a special 
public hearing on the need for such interim rate increase and the company, at least one 
week prior to such hearing, notifies each customer who would be affected by the interim 
rate increase that such an increase is being requested. The company shall include the 
notice in a mailing of customer bills, unless such a mailing would not provide timely 
notice, in which case the department shall authorize an alternative manner of providing 
such notice. Any such interim rate increase shall only be permitted if the public service 
company submits an assurance satisfactory to the department, which may include a bond 
with surety, of the company's ability and willingness to refund to its customers with 
interest such amounts as the company may collect from such interim rates in excess of 
the rates approved by the department in accordance with subsection (a) of this section. 
The department shall order a refund in an amount equal to the excess, if any, of the 
amount collected pursuant to the interim rates over the amount which would have been 
collected pursuant to the rates finally approved by the department in accordance with 
subsection (a) of this section or fixed at the conclusion of any appeal taken as a result 
of any finding by the department. Such refund ordered by the department shall be paid 
by the company to its customers in such amounts and by such procedure as ordered by 
the department.
      (e) If the department finds that the imposition of any increase in rates would create 
a hardship for a municipality, because such increase is not reflected in its then current 
budget, or cannot be included in the budget of its fiscal year which begins less than 
five months after the effective date of such increase, the department may defer the 
applicability of such increase with respect to services furnished to such municipality 
until the fiscal year of such municipality beginning not less than five months following 
the effective date of such increase; provided the revenues lost to the public service 
company through such deferral shall be paid to the public service company by the municipality in its first fiscal year following the period of such deferral.
      (f) Any public service company, as defined in section 16-1, filing an application 
with the Department of Public Utility Control to reopen a rate proceeding under this 
section, which application proposes to increase the company's revenues or any rate or 
charge of the company by five per cent or more, shall, not later than one week prior to 
the hearing under the reopened proceeding, notify each customer who would be affected 
thereby that such an application is being filed. Such notice shall indicate the rate increases proposed in the application. The company shall include the notice in a mailing 
of customer bills, unless such a mailing would not provide timely notice to customers 
of the reopening of the proceeding, in which case the department shall authorize an 
alternative manner of providing such notice.
      (g) The department shall hold either a special public hearing or combine an investigation with an ongoing four-year review conducted in accordance with section 16-19a 
or with a general rate hearing conducted in accordance with subsection (a) of this section 
on the need for an interim rate decrease (1) when a public service company has, for six 
consecutive months, earned a return on equity which exceeds the return authorized by 
the department by at least one percentage point, (2) if it finds that any change in municipal, state or federal tax law creates a significant increase in a company's rate of return, 
or (3) if it finds that a public service company may be collecting rates which are more than 
just, reasonable and adequate, as determined by the department, provided the department 
shall require appropriate notice of hearing to the company and its customers who would 
be affected by an interim rate decrease in such form as the department deems reasonable. 
The company shall be required to demonstrate to the satisfaction of the department that 
earning such a return on equity or collecting rates which are more than just, reasonable 
and adequate is directly beneficial to its customers. At the completion of the proceeding, 
the department may order an interim rate decrease if it finds that such return on equity 
or rates exceeds a reasonable rate of return or is more than just, reasonable and adequate 
as determined by the department. Any such interim rate decrease shall be subject to a 
customer surcharge if the interim rates collected by the company are less than the rates 
finally approved by the department or fixed at the conclusion of any appeal taken as a 
result of any finding by the department. Such surcharge shall be assessed against customers in such amounts and by such procedure as ordered by the department.
      (h) The provisions of this section shall not apply to the regulation of a telecommunications service which is a competitive service, as defined in section 16-247a, or to a 
telecommunications service to which an approved plan for an alternative form of regulation applies, pursuant to section 16-247k.
