Mahalo for your interest in KIUC's pending rate case. On December 28, 2022, KIUC filed a request for a revenue increase with the Hawaii Public Utilities Commission (PUC). On November 27, 2023, the PUC issued an interim decision and order allowing KIUC to increase rates pending a final decision. The interim increase became effective as of January 11, 2024. More information on that decision can be found on this page under FAQ's, News and Updates and PUC Filing Documents.
It's important to us that our members have comprehensive and current information. Please check back here for updates.
KIUC is proposing rates that are designed to collect sufficient revenue for operations while avoiding excessive rate impacts to members. We also seek to simplify bill structure and predictability, and make reasonable progress toward aligning revenue collection with cost causation as assessed in our allocated cost-of-service study.
The last base rate increase was granted in 2010. Since that time, there have been cumulative inflation impacts of 37%, while KIUC sales have increased less than 5%. A rate adjustment is necessary for KIUC to maintain financial stability and meet lender requirements.
A base rate is a fixed kilowatt hour (kWh) charge for electricity consumed that is independent of other variables, such as the current price of oil.
KIUC is seeking approval for an increase of 9.4% in revenues across rate classes. Rate classes are being treated equally in KIUC's proposal. In other words, the residential, small power, large power, and other classes of members will each generate an additional 9.4% in revenue annually under KIUC's proposal. The only rate class that has been assigned a greater than 9.4% increase is street lighting.
Changes are also being proposed to other items on a member's bill, such as the monthly customer charge and demand charges (where applicable). Also, Large Power customers (Schedules L and P) will now be combined into one rate class.
More information on how the proposal would impact your bill can be found on Exhibit DK-504 of the rate case filing.
That claim is FALSE. KIUC has asked the PUC for a 9.4% increase in revenues across rate classes. The increase is being spread equally among residential and commercial rate classes. In other words, the revenue collected from each of these rate classes would increase by 9.4% if KIUC's proposal is adopted by the Hawaii Public Utilities Commission.
This does not mean that every member of KIUC could expect a 9.4% increase in their monthly bills. There are many factors that contribute to how much your bill is impacted. For residential members, the increase will range from 10.8% for members using 250 kWh per month, to 8.9% for members using 1000 kWh per month. Our average member uses 500 kWh per month, for which the increase is projected to be 9.4% per month.
More information on projected increases by rate class and energy usage can be found here.
KIUC has requested and received a base rate increase only once since starting operations in 2002. That base rate increase was approved by the Hawaii Public Utilities Commission in 2010. This will be the second base rate increase request in KIUC’s 20-year history.
Spread over the 12 years since the last base rate increase, the proposed increase calculates to less than 1% per year.
The base rate as established in the 2010 rate case is $0.34743 per kWh for members in the residential class.
KIUC's base rate remains the same from month to month. When posting its monthly kWh charge for electricity, KIUC includes an Energy Rate Adjustment Clause – or ERAC – which is the amount KIUC is allowed to adjust rates monthly, primarily based on the current cost of oil. When the cost of oil is low, the ERAC may result in a decrease of the base rate for that month. When the cost of oil is high, the ERAC may result in an increase in the base rate for that month.
KIUC’s rates have stabilized significantly over the past ten years, thanks in great measure to replacing fossil fuel with renewable energy purchased under long-term, fixed price power purchase agreements. KIUC estimates that increasing use of renewables has saved KIUC members more than $56 million since 2010. The first chart below illustrates how rates have stabilized as the percentage of renewables have increased. The second chart estimates the amount of savings achieved each year by displacing diesel with renewable generation.
That depends on the current cost of oil. However, over the past ten years, renewables have been less expensive than oil most of the time.
As an illustration of this, with 70% of KIUC’s generation coming from renewables in 2021, the impact of the recent oil price spike was minimal for members. While electricity rates on Kauai rose between 5% and 10% in 2021 and 2022, the rest of the state has experienced increases from 30 to 50%. This is because KIUC's renewable generation is based on long-term power purchase agreements at fixed prices. This buffers KIUC and its members from spikes in oil prices.
KIUC estimates that renewable generation has saved members more than $50 million dollars when compared to energy that would have been produced at the cost of oil.
When KIUC began operating as a cooperative in 2002, its rates were the highest in the State of Hawaii: more than 70% higher than Oahu’s rates.
As of May 2022, KIUC had closed that gap and since then has posted the lowest residential rates of any island in the State of Hawaii. This is a remarkable achievement given that Oahu has more than ten times the number of customers as Kauai. In recent months, KIUC's rates have been roughly 15% lower than Oahu's.
This has been achieved by replacing the volatility of oil pricing with fixed-price renewables.
Since the last base rate increase in 2010, the Consumer Price Index (CPI) has risen a cumulative total of around 36% in Hawaii. While KIUC has managed to keep its controllable costs below the inflation rate, electricity sales have not kept pace. There is a growing gap between expenses and revenues, given that sales have increased only 5% since 2010.
Inflation, along with escalating costs associated with endangered species compliance and more than $80 million invested in necessary improvements to the grid and IT infrastructure, have created pressure on KIUC’s balance sheet over time.
As a not-for-profit organization, KIUC must to maintain a comfortable net margin, which is the money left over from sales after subtracting expenses. In the past few years margins have decreased to the point that KIUC is in danger of no longer meeting lender requirements.
Note that the margins reported in this graph for 2020, 2021 and 2022 include Lost Gross Margins (LGM) KIUC has been allowed to accrue due to a loss in sales from COVID 19. Learn more about LGM here: https://tinyurl.com/3nbwj2td
Some of the major cost items incurred by KIUC since 2010 include:
- Capital expenditures of $88.8 million, including: IT/Cybersecurity enhancements, new substations to accommodate renewable energy facilities, transmission and distribution system replacements and upgrades, installation of LED streetlights island-wide, tree trimming and disaster recovery from Hurricane Lane in 2018 and the April 2018 flooding event.
- Habitat Conservation Plan costs totaling $64 million, including minimization measures such as line reconfiguration and installation of bird diverters, and mitigation measures such as predator control fencing and the Save our Shearwaters Program.
Since the last base rate increase, KIUC has managed to keep its controllable costs below inflation rate with the following measures:
- Reducing staffing levels from 161 full-time employees in 2009 to 134 in 2022.
- Replacing fossil fuel generation with renewables at an estimated savings of more than $56 million since 2010.
- Securing a Paycheck Protection Program loan $2.8 million, which was forgiven.
- Restructuring existing debt, which reduced debt service by approximately $2.7 million in 2020 and will save KIUC $5.5 million annually from 2021 through 2035.
New renewable projects currently in development, such as the West Kauai Energy Project, will further reduce dependence on fossil fuel and stabilize rates.
Like any business, KIUC cost of operation is impacted by inflation. The Consumer Price Index for Hawaii has risen cumulatively 35% since 2010. Although KIUC has been successful containing costs below the rate of inflation, the rise in costs over time coupled with a low sales growth rate has impacted net margins significantly. More information on KIUC’s financial condition can be found in the FAQ titled “Why a Base Rate Increase Now?”.
KIUC will be proposing an increase in base rates and other charges that will equate to a 9.4% increase in revenue for each customer class. More information on how the increase will affect you, based on your energy usage, can be found here.
Although the rate request will be filed in December 2022, residents likely won’t see an increase until late 2023. The request will follow a procedure outlined by the Hawaii Public Utilities Commission which is detailed and takes months to complete.
The process of approving new rates by the Public Utilities Commission will take months to complete. We estimate new rates will take effect no earlier than mid- or late-2023.
