HONOLULU, June 3, 2013 /PRNewswire/ --Hawaiian Electric Industries, Inc.
(NYSE: HE) (HEI) today announced that as a result of the Maui Electric
Company, Limited (MECO) 2012 test year final rate case decision and order
(D&O) issued by the Public Utilities Commission of the State of Hawaii (PUC)
on May31,2013, it has lowered its 2013 earnings per share (EPS) guidance
from its previous range of $1.58 to $1.68 to a revised range of $1.52 to $1.62
on a GAAP basis. Excluding the refund of MECO revenues attributed to 2012,
the EPS guidance range would be $0.02 higher or $1.54 to $1.64. The
corresponding revision to the EPS guidance for Hawaiian Electric Company, Inc.
(HECO) and its subsidiaries reduces the previous range from $1.23 to $1.29 to
a revised range of $1.17 to $1.23 on a GAAP basis (or $1.19 to $1.25 excluding
the $0.02 discussed above). The revised guidance assumes $7.8 million lower
MECO annual revenues in accordance with the MECO final D&O. Of this amount
$1.5 million relates to pension and other postretirement benefits (OPEB) which
will be offset by lower pension expense (as a result of the pension tracking
mechanism). The EPS guidance assumptions previously disclosed in HEI's fourth
quarter 2012 and first quarter 2013 earnings call remain unchanged.

HECO is currently evaluating the impact of the MECO final D&O to the
previously disclosed guidance for HECO's consolidated structural gap of 80 to
110 basis points between its allowed return on average equity (ROACE) and the
ROACE it actually achieves. An update, if any, will be provided in the HEI
second quarter 2013 earnings call and webcast.

On May 31, 2013, the PUC issued a final D&O in the MECO 2012 test year
proceeding. The final D&O approved an increase in annual revenues of $5.3
million, which is $7.8 million less than the interim increase that had been in
effect since June1, 2012 (including the $3.4 million of MECO Revenue
Adjustment Mechanism (RAM) revenues approved in the "Annual Decoupling
Filings" section below, the net impact to annual revenues is $4.4 million less
than the interim increase). Reductions from the interim D&O relate primarily

(in millions)
Lower ROACE                                      $4.0
Customer Information System (CIS) expenses       0.3
Pension and OPEB expense based on 3-year average 1.5
Integrated resource planning (IRP) expenses      0.9
Study costs                                      1.1
Total adjustment                                 $7.8

According to the PUC, the reduction in the allowed ROACE from the stipulated
ROACE of 10% to the final approved ROACE of 9% is composed of 0.5% allocation
to lower interest rates and 0.5% for over curtailment of renewable energy.

The reduction in the pension and OPEB expense is due to applying a three-year
average in the calculation of pension costs for the purpose of the 2012 test
year. This is not a PUC decision to change the pension and OPEB tracking
mechanisms, although the PUC emphasizes the need to evaluate alternatives to
decrease or limit the growth in employee benefit costs.

The PUC also continues MECO's existing energy cost adjustment clause (ECAC)
and power purchase adjustment clause (PPAC) design. The PUC will consider
HECO, Hawaii Electric Light Company (HELCO), and MECO's (the Hawaiian Electric
Companies) future actions to reduce fuel costs and increase use of renewable
energy as it continues to review this matter in the future.

Since the final rate increase is lower than the interim increase currently in
effect, MECO will refund to customers approximately $8.1 million, which
includes interest accrued since June1, 2012, the date on which interim rate
increases were previously implemented.

A summary of the interim D&O in effect and final D&O is as follows:

                                  InterimD&O       FinalD&O

                                  6/1/2012          5/31/2013
                                  $13.1 million     $5.3 million
Revenue increase
                                  (3.2% increase)  (1.3% increase)
ROACE (%)                         10.00 %           9.00 %
Common equity capitalization (%)  56.86 %           56.86 %
Return on average rate base (%)   7.91 %            7.34 %
Average rate base amount          $393 million      $393 million

The PUC also directed that, within 30 days from the issuance date of the final
D&O, MECO file documentation regarding the re-setting of its target heat rate
to take into account the operation of the Auwahi wind farm, as well as make
its curtailment information readily available to the public on its website.
The PUC also directed that, within 90 days from the issuance date of the final
D&O, MECO file a System Improvement and Curtailment Reduction Plan. MECO
continues to review the D&O and is considering what further action, if any, it
may take.

On May 31, 2013, the PUC approved the revised annual decoupling filings for
tariffed rates for HECO, HELCO and MECO that will be effective from June 1,
2013 through May 31, 2014. The revised tariffed rates include: (1) the
incremental RAM adjusted revenues (the components of which are shown below),
(2) the accrued earnings sharing credits to be refunded, and (3) the amount of
the accrued Revenue Balancing Account (RBA) balance as of December31, 2012
(and associated revenue taxes) to be collected. The amounts approved as noted
below reflect the Hawaiian Electric Companies' agreements with the position of
the Consumer Advocate which are not substantially different than the amounts
filed by the Hawaiian Electric Companies in March 2013.

Accrued RBA balance (and associated revenue taxes) to be  $55.4   $4.9   $5.8

Also on May 31, 2013, as provided for in its original order issued in 2010
approving decoupling and citing three years of implementation experience for
HECO, the PUC opened an investigative docket to review whether the decoupling
mechanism is functioning as intended. The PUC affirmed its support for the
continuation of the sales decoupling (RBA) mechanism and stated its interest
in evaluating the RAM to ensure it provides the appropriate balance of risks,
costs, incentives and performance requirements, as well as administrative
efficiency and whether the current interest rate applied to the outstanding
RBA balance is reasonable.

The Hawaiian Electric Companies and the Consumer Advocate are named as parties
to this proceeding and are directed to file a statement of position no later
than twenty days from the order (i.e., by June 20, 2013).
