Phasing-out the Low Fixed Charge Tariff regulations

What are low fixed charges?

Video Transcript

[A man is looking at a computer screen and comparing 2 electricity plans – one plan is a low-use plan for households that don’t use much power, that other is a standard-use plan for high electricity use.]

[Narrator:] “When you sign up with an electricity company, you can choose from either a standard-use or a low-use plan – depending on how much electricity you think you’ll use.”

[The scene changes to a suburban street and scans past a row of houses that are connected to power lines.]

[Narrator:] “Regardless of what plan you’re on, you’ll pay a daily fixed charge that covers part of the costs of being connected to the electricity grid. You then pay for the power you actually use on top of that.”

[The next scene shows a man and a woman inside a home – they represent a household that pays low fixed charges because they don’t use much electricity.]

[Narrator:] “If you’re on a low-use plan, the amount you pay for the daily fixed charge is limited by the low fixed charge regulations. This can be a big discount towards the actual cost of providing and maintaining power to your home.”

[More people are added to the scene to show an intergenerational household. This represents a household that pays standard fixed charges because they use a lot of electricity.]

[Narrator] “But if you’re on a standard-use plan, your daily fixed charge could be quite a bit more. You may be contributing more than your fair share.”

[The scene changes again to show a scroll of paper appears on the screen that says ‘2004 regulations’.]

[Narrator:] “The regulations introduced in 2004, required power companies to offer households the option of a low-use plan, where the fixed charge was no more than 30 cents a day.”

[The next scene is a single house at night time with the lights on. Some lights turn off to show the household is trying to use less power to save money.]

[Narrator:] “It was created to help reduce bills for households with low electricity use and also encourage people to use less power.”

[The next scene shows 3 plinths with people standing on top, representing 3 different households. The first plinth shows a man and a woman. They are a low-use household that pays the low fixed charge, but a higher rate for the electricity they use. They are wearing winter clothes because they are trying to save money by using less electricity and aren’t heating their home. Their plinth goes down to show they are disadvantaged by the regulations.]

[The second plinth in this scene shows a small family who represent a household that uses an average amount of power. Their plinth stays the same height because the low fixed charge regulations do not greatly change their power bills or negatively affect their health. The last plinth shows a wealthy couple who represent a low-use household. They can afford to live in an energy-efficient house, which means they pay the cheaper low fixed charge. Their plinth rises because they are advantaged.]

[Narrator:] “While it did help some, it unintentionally harmed others.”

[The next scene goes to the home of the couple on the first plinth. They look sad and are wearing winter jackets inside.]

[Narrator:] "Many households can’t afford to reduce their power use by improving the energy efficiency of their home or installing solar panels. Instead, they limit their power use by under‑heating their homes. This can lead to cold, damp homes and more health problems.”

[As the narrator says this, the scene zooms in on the heater dial, which turns off because they can’t afford the costs of running it. There are tissues and medicine on the table as the couple get sick from living in a cold home.]

[The scene changes to the wealthy couple who are outside their home that is being built. They are having double glazed windows and new insulation installed so their home will be energy efficient and not require much power to heat.]

[Narrator:] “Households that have double-glazing and proper insulation, and can afford energy-efficient appliances or solar panels, don’t need as much electricity to heat their homes. These households don’t use as much power and can benefit from the low fixed charges.”

[The scene changes again to show a large, intergenerational family outside their home. They have an electric car and there are antenna on the roof to indicate they use a lot of electricity.]

[The next house over is run-down and looks cold and draughty. Inside there are 3 students who look cold and miserable. There are trying to heat their home with inefficient bar heaters.]

[Narrator:] “Households on the standard-use plan use more power. This could be because they are a large family, have lots of appliances like electric vehicles or have a cold and draughty house that’s hard to heat.”

[The final scene shows 5 plinths at different heights, with the figures of each household on top. The plinths are at different heights to show different levels of advantage or disadvantage caused by the low fixed charge regulations.]

[Narrator:] "The way we use electricity has changed since the regulations were introduced in 2004. Data from 2021 found about 68% of households were able to go on a low-use plan. This is making power bills more expensive for those on standard plans, which includes some households that can least afford it.”

[Narrator:] “The low fixed charge regulations are unfair to some households, which is why the government is phasing them out.”

[As she says this the plinths then move to the same height to show removing the regulations creates a more even playing field for all households.]

Low-use plans and standard-use plans

Households on low-use electricity plans pay a discounted fixed charge, which was capped under the Low Fixed Charge Tariff regulations, and will remain capped throughout the 5-year phase-out. This is on top of paying variable charges relating to the actual amount of electricity they use. Households on low-use plans pay higher charges relating to electricity used than other households on standard-use plans.

The low-use plan has been a good deal for households that use less than 8,000kWh of power a year (or 9,000kWh a year for the lower South Island). As shown in the graph below, under the regulations, households that used more electricity than this have been better off being on a standard-use plan. Their fixed charge was higher, but the rate they pay for actual electricity used was lower. This will remain the case throughout the phase-out.

Households will pay more than they need to if they are on the wrong plan.

Line graph of comparison between annual bills of standard-use plans and low-use plans

Text description of graph

The graph has 2 lines rising upwards from the lower left-hand corner. The blue line represents the amount people on a standard-use plan pay for power across different levels of annual power use, while the orange line represents the amount people pay on a low-use plan. The graph shows that households on low-use plans pay less than households on standard-use plans if they use less than 8,000kWh of power a year. While households on standard-use plans pay less than households on low-use plans if they use more than 8,000kWh of power a year. The 2 lines intersect at 8,000kWh, which means households using this much power would pay the same amount, regardless of whether they’re on a low-use plan or a standard-use plan. For households in the lower South Island, the 2 lines would intersect at 9,000kWh.

Households may use a low amount of electricity if they:

have a small, or very energy-efficient house,
have a low number of occupants,
use another type of fuel, such as gas,
use another energy resource, such as solar power,
deliberately use little electricity, for example under-heating their home, or
are a holiday home* or otherwise not regularly occupied.

*Low-use plans are designed for primary residences only. Holiday homes should be excluded from these pricing plans.

Households may use a higher amount of electricity if they:

have a large house,
have a higher number of occupants,
have a draughty, poorly insulated home that is hard to heat, or
use many electronic appliances or inefficient appliances.

Problems with the Low Fixed Charge Tariff regulations

The Low Fixed Charge Tariff regulations were introduced in 2004 to provide electricity plans with a discounted fixed charge that aimed to reduce power bills for low-use, low-income households. However, as the regulations were poorly targeted, they only help some low-use households and have pushed others into greater energy hardship, including many low-income families with high electricity use, for example larger families. The Low Fixed Charge Tariff regulations also have had unintended effects on households’ electricity use, created barriers for industry to undertake distribution pricing reform and increased complexity and confusion for consumers.

Phasing-out the Low Fixed Charge Tariff regulations was a recommendation to government by the independent Electricity Price Review. The Review recommended the regulations be phased-out over 5 years to help moderate the impact of the increasing fixed charges on most low-use households.

Low fixed charges:

create an unfair playing field

Households pay for the amount of power they use, and it’s fair that households that use a lot of electricity have higher bills than those who use less. But high-use households shouldn’t also have to pay more for the fixed cost of delivering power to their homes. These costs to electricity retailers and distributors are the same, regardless of whether power is going to a low-use household or a high-use household.

The average electricity use of New Zealand households has significantly reduced since the regulations were introduced in 2004. Data from 2021 showed 68% of all households were low users and could take advantage of the discounted low fixed charge. This left an increasingly smaller proportion of households paying the standard fixed charge, and facing even higher power bills to make up for the under-recovery of fixed charges from households paying the discounted low fixed charge.

are poorly targeted

The regulations were designed to help low-income households with low power use. But electricity use is a poor indicator of socio-economic status, so there are many wealthier households benefitting from the low fixed charges, and whose network costs are being subsidised by others, including some low-income households.

Households paying the standard fixed charge, with higher power use, are sometimes those that can least afford it. And the Low Fixed Charge Tariff regulations are making it even harder for these households to pay their power bills.

create a barrier to better distribution pricing

Electricity use in New Zealand is expected to grow as we increasingly rely on electricity in our day-to-day lives, for example through increased uptake of electric forms of heating, e-bikes and electric vehicles. This increased electrification will have significant implications for the electricity sector and will require a shift in when we use electricity and how we may pay for it at different times.

The Low Fixed Charge Tariff regulations are a well-recognised barrier to distribution pricing reform. By removing the regulations, the electricity industry will more easily be able to manage the increased load on the network through new distribution pricing structures, such as Time of Use pricing. This will allow the industry to avoid costly network upgrades that would otherwise see costs passed onto consumers. All households are likely to benefit from new distribution pricing in the long term.

can encourage households to under-heat their homes

create confusion

The regulations make it harder for households to ensure they’re not paying more by being on the wrong plan. Data from 2021 showed that an estimated 120,000 households signed up for a low-use plan where they pay a low fixed daily charge, despite being high users of electricity. These households would have had lower power bills if they were on a standard-use plan. Of these, about 45,000 households were estimated to have paid more than $200 extra a year because of being on the wrong plan. This was despite obligations on retailers to contact households at least once a year to promote the appropriate plan for the amount of power they use.

discourage uptake of electric vehicles and other electric, more sustainable technologies

Households on low-use plans pay a higher rate for the actual amount of electricity used. This higher rate can discourage people from investing in electric vehicles and other electric appliances, like heat pumps, which would see their power use, and their power bills, increase. Instead, low-use plans incentivise households to choose non-electric options such as petrol cars and gas burners that are worse for the environment.

favour households that can afford to be energy efficient and install solar panels

Households that can afford to be more energy efficient—through double glazing, energy-efficient appliances and solar panels—save on their power bills by using less electricity. They’re getting another discount if these energy-savings mean they can go on a low-use plan and pay the low fixed charge.

Some lower-income households are being unfairly penalised for not being able to afford energy-saving measures to reduce their electricity use.

are impeding environmental efforts

The way we think about electricity use and its impact on the environment has changed significantly since the regulations were designed. In 2004, it was assumed that conserving electricity resulted in environmental benefits.

But it’s now well understood that New Zealand’s largely renewable electricity system will play an important role in helping reduce our carbon emissions and meet our climate change goals. The government and many in the private sector are working hard to replace fossil-fuelled technologies with electric alternatives.

With this in mind, New Zealanders should be encouraged to use more electricity, not less, if it means switching to more eco-friendly electric technologies such as heat pumps and EVs.

Phasing-out the regulations

In September 2021, the Government agreed to phase-out the regulations.

Minister of Energy and Resources announces phase-out of low fixed charge tariff regulations(external link) — Beehive website

The regulations set the maximum amount allowed for the fixed charge on electricity plans for low users. During each year of the 5-year phase-out, the maximum amount for the daily fixed charge will increase by 30 cents. The increase, which started on 1 April 2022, is being applied gradually over 5 years to minimise the impact to households who were previously paying a discounted fixed charge.

This decision was strongly supported by electricity retailers and distribution companies who advocated for removing the regulations. Their view is that the regulations limit their ability to introduce pricing reforms to reflect the costs they face.

Removing the regulations will help power companies introduce pricing plans, like Time of Use pricing, where households get cheaper rates if they can shift their power use away from peak periods. This has the potential to save households money while also reducing the need for expensive network upgrades that could see further costs passed onto households’ bills.

Removing the regulations does not change power companies’ ability to continue to offer plans with low fixed charges. The regulations only set the maximum amount that can be charged. Power companies may choose to set lower rates for their fixed charges for low-use households.

The Government has been clear in its expectation that power companies would not increase their profits as a result of phasing out the regulations. This is due to how the regulations were designed. The regulations were designed to limit the amount of revenue power companies could recover from fixed charges for low-user households. The shortfall in revenue recovered from low-use households was paid for by standard-user households, who faced higher fixed charges. The impact of this regulatory change means that, while low-use households may pay slightly more and standard-use households may pay slightly less, power companies will ultimately recover the same amount of revenue overall.

However, it is important to be aware that other factors will also impact household power bills such as: increasing wholesale electricity prices, changes in how transmission charges are calculated, general inflation, and the need for increased investment in electricity network infrastructure.

Maximum low fixed charge (excluding GST)
Prior to 1 April 2022	$0.30 a day
1 April, 2022	$0.60 a day
1 April, 2023	$0.90 a day
1 April, 2024	$1.20 a day
1 April, 2025	$1.50 a day
1 April, 2026	$1.80 a day
1 April, 2027	Regulations removed. Power companies are no longer required to offer customers a low fixed charge.

Text explanation of table

From 1 April 2022, the maximum low fixed charge will increase by 30 cents each year until 1 April 2027. This means the maximum low fixed charge increased from 30 cents a day to 60 cents per day on 1 April 2022. It will then increase to 90 cents per day on 1 April 2023, $1.20 per day on 1 April 2024, $1.50 per day on 1 April 2025 and $1.80 per day on 1 April 2026. On 1 April 2027, the regulations will be removed and power companies will no longer be required to offer customers a low fixed charge.

Time of Using pricing

Time of Use pricing more accurately reflects the time-varying nature of electricity costs than traditional tariffs that charge households a flat price regardless of when electricity is used. These pricing plans work by using smart meters that provide accurate measurements of how much electricity is being used at different times of the day. These price signals are designed to encourage households to shift their non-essential electricity use to times when there is lower demand on the network, providing opportunities to save on their power bill. Shifting non-essential electricity use to times when demand is low can reduce the installed network capacity required to meet high peak demand, helping reduce the need for expensive network upgrades.

An illustrative example of what may be expected for a household on a low-use plan that uses an average amount of power is shown below.

Prior to the phase-out, the low fixed charge paid by this household makes up a small proportion of its total power bill. If this household remains on the same pricing plan during the phase-out, and its power company chooses to increase the fixed charges in line with the maximum allowed each year, then this household could expect to pay more in fixed charges but less for the actual power used. In this example, a household on a low-use plan using the average amount of power may expect to pay slightly less overall.

Text description of diagram

The diagram shows 2 bars. The first bar represents a power bill of a household on a low-use plan that uses the average amount of power, prior to the phase-out beginning in April 2022. The second bar represents the same household on a new pricing plan in 2027 when the low fixed charge has increased. The bars are divided in 2 to show the proportion of the bill that is the fixed charge, and the proportion that is the cost for power used.

In the first bar, the fixed charge represents a very small proportion of their power bill, with the majority of the bill representing the costs for power used. The second bar pays slightly less in 2027, but the fixed charge is now a larger proportion of the power bill, although the majority of the bill still represents costs for actual power used.

Analysis of the impact on households

There is some uncertainty over how power companies will choose to structure their pricing plans during the phase-out, and therefore what the impact on households will be.

Overall about 60% of all households—about 970,000 households—are expected to have lower power bills during the phase-out as the lower rate for electricity used has a greater impact on their overall power bill. These households are likely to be those on standard-use plans and those on low-use plans using more than 6,500kWh a year.

Reviewing changes to power companies’ pricing

Considering the uncertainty over how industry will choose to structure their pricing plans during the phase-out and the impact it may have, MBIE will conduct a mid-point review of the phase-out. The review, expected to be carried out in late-2023, will study the impacts of the phase-out on households and if any additional support measures may be required.

In May 2023, the Electricity Retailers’ Association New Zealand (ERANZ) published a report that suggests the phase-out is meeting its objectives. Key findings from this analysis show:

Variable charges for households, on average, are 2.6 cents/kWh (excl. GST) lower from 1 April 2023 than they otherwise would have been.
Average power bills for households with higher electricity use, which include many low-income households, are $78/year lower than they otherwise would have been, while average bills for lower-use households have increased by $39/year.
There is greater pricing innovation across retail plans, with an increase in the number of electricity plans on offer with a Time-of-Use component.

This analysis also found that phasing out the Low Fixed Charge Tariff regulations is not resulting in increased revenue for power companies. The data suggests while the fixed charges on low-use plans are increasing, this is being offset by decreasing costs for the power a household uses (the variable charge).

Long-term benefits

In addition, all households are expected to benefit from the regulations being removed in the long term. The revenue collected from fixed charges goes towards maintaining the national grid – the lines that deliver electricity to households. New Zealand’s electricity use is expected to grow in the future. This could result in the industry having to undertake expensive upgrades so the lines network can cope with the extra demand; and these extra costs could be passed on to consumers.

However by removing the Low Fixed Charge Tariff regulations, power companies will more easily be able to manage the extra load by introducing new pricing plans that encourage households to spread their electricity use across different times of the day. (See Time of Use pricing above). This will help power companies to avoid expensive upgrades that could see the costs passed on to consumers. Households also get more options of pricing plans where they can control their electricity use to take advantage of cheaper off-peak electricity prices.

Support for households during the phase-out

Removing the Low Fixed Charge Tariff regulations is essential for creating a fairer, more equitable electricity pricing system. However the households that have been benefitting from the regulations may gradually face higher fixed charges and their power bills may go up during the phase-out period.

A power credit scheme has been developed to support low-use households who are struggling to pay their power bills during the phase-out.
