Challenge
In 2010 amaysim had launched in the Australian mobile plan market, introducing Australia's first fixed price pre-paid mobile plans – a now universal solution to the billing complexity and bill shock that had previously been the norm for mobile phone plans.
Recognizing that complex billing and bill shock were still the norm for electricity bills, amaysim bought Click Energy in 2017, planning a similar disruption for electricity plans.
Market context
Why Australian energy plans are terrible
Taking advantage of consumer behaviour, Australian post-paid electricity retail plans are designed to actively exploit Australian consumers. I've sat in their meetings: Sales managers and product owners in this industry actively enact product design and marketing plans that would be considered indefensible in other contexts.
Complex plans cause consumer confusion and disengagement
Every standard electricity plan is composed of a daily supply charge and a power consumption charge. Because a plan that has low usage charges inevitably has high supply charges, and vice versa, comparing competing plans is mathematically challenging for most users. Accurately comparing different plans really requires expert level skills with spreadsheet or calculator - many consumers feel like it’s an impossible task.
Retailers exploit disengaged customers
Because plan complexity makes plan choice such hard work and so confusing, most electricity consumers give up on making active consumer decisions.
Retailers take cynical advantage of this. Consumers sign up on competitively priced acquisition, not realizing that over the next one or two years the retailer will schedule in multiple rate hikes, adding 10-20% to the original plan prices. The retailer will frame this as market led price hikes, even as they launch new acquisition plans at the original price points.
Because consumption varies, and bills are hard to read and understand, most consumers fail to notice these price rises and stay on their overpriced plans. While unpredictable wholesale costs require retailers to hedge against risk, this is clearly predatory behavior - energy retailers regularly post higher profit margins than comparable utilities.
The consumer perception of value is deeply corrupted
Because of the high profit that can be extracted from long term customers, retailers heavily discount acquisition plans, even pricing them below cost at times.
Because of rising energy prices, and the public conversations about them, consumers feel like electricity is overpriced, even when comparing these “cheap” acquisition prices.
Bill shock is common and traumatic
Unpredictable electricity consumption, combined with the retailers tendency to lift rates by stealth, means that surprisingly large bills are common in the industry. This experience is referred as “bill shock” and causes real and memorable hardship to the consumers who experience it.
A prime example was interviewing a test subject with significant visual impairment. He had been unable to read intentionally obscure text notifying him of a 20% price hike. He only discovered the price hike through bill-shock and the emotional damage lasted much longer than the financial hardship.
user research
Interviewing energy customers
As amaysim’s senior energy UX designer I led 2 rounds of user interviews, interviewing Australian energy consumers in NSW and Victoria. Interviews were held at a time where high energy prices had become a public and political talking point. Subjects were interviewed about:
Their experience and history as energy consumers
Their pain points
How they chose between competing energy plans
Our high level findings confirmed:
"They're all cheats": High levels of distrust and cynicism towards retailers
"These plans are so confusing!": User frustration over complex plan structures
"I was on the phone for an hour": Frequent stories of consumer frustration and distress
"I just burst into tears": The personal cost of bill-shock
Based on these finding the product team assumed that the energy market was ripe for disruption.

User persona design
User persona design
Based on user interviews I devised 3 user personas to explain different user behaviors. These user personas were defined by user behavior and world-views rather than gender, age or other demographic differences.
Persona 1: PRYCE HUNTER
“Low trust, High market participation”
About a third of recruited test subjects interviewed were “Pryce Hunters”. These users were notable because:
They were aware of the retailers’ strategy of raising prices for long term customers.
They found it easy to understand and compare energy plans (frequently using spreadsheets)
They changed plans or retailers every 9-12 months, exploiting sign-up offers
They actively enjoyed bargain hunting
Because of the time and education requirements, Pryce Hunters tended towards being younger, single and professional.
Persona 2: BILL EASY
“High trust, Low-medium market participation”
Just over half of all test subjects were “Bill Easy” users. These users were notable because:
They had relatively low awareness that retailers raised prices for long term customers
They believed that customer loyalty should be rewarded, not exploited
Low understanding of how plans work, or how to compare competing plans
They usually changed plans or retailers every 3-4 years
They felt vaguely guilty or uneasy that they weren't shopping for a better plan
Tending towards being time poor, Bill Easy was often a busy parent
Persona 3: SUE SPICIOUS
“Low trust, Low market participation”
Sue Spicious were the least common persona. While they were seen throughout the interview process they were only clearly identified during proposition testing:
Very high levels of suspicion and cynicism towards retailers (and any other corporate entity)
Very low understanding of how plans work, or how to compare competing plans
Doesn’t believe that they are capable of finding a better plan
Ironically, Sue Spicious was typically the slowest to change plans (5+ years), and thus on the worst deal
Shopping for a new plan only seems to be initiated by moving house
Persona 1: PRYCE HUNTER
“Low trust, High market participation”
About a third of recruited test subjects interviewed were “Pryce Hunters”. These users were notable because:

Wireframes expand on Product Team concepts
I built a number of wireframes that expanded on ideas generated by the product team. These higher fidelity models helped the product team mature and compare their propositions.
User testing with interactive prototypes
I then built 4 different interactive product prototypes which were tested with recruited energy consumers. These user tests were designed to collect qualitative feedback on product ideas and to sense-check their relative value propositions.
Users reported that they wanted wanted energy plans that included:
Pricing transparency: Bills that are easy to understand
Pricing transparency: Bills that are easy to understand
Predictable billing: No bill shock
Predictable billing: No bill shock
While user tests were generally positive, no final product model had yet been settled on. More importantly, propositions had not undergone market acceptance testing.
Product design is cut short by corporate timelines
Unfortunately (hidden) corporate timelines triggered an executive team decision to launch these new energy plans before appropriate UX work could be completed. Our team shifted to designing user flows and interfaces, while we waited for the product team to define what the final product design would be.
When a product definition was finally presented it looked good, however it had not been validated through user testing, and this would become evident later.

Making energy bills understandable
Test subjects stated repeatedly in user testing that they were prepared to pay a small premium for simpler, safer energy plans. This extended past the purchase experience to include billing as well. Only Pryce Hunters knew how to accurately read an energy bill, most consumers found them impenetrable.
Our design team's insight was that users did not think of their retailer when they turned on a power switch, but only when they received a bill. Receiving and paying bills was the product experience for an energy retailer.
Our design team set about redesigning the billing experience by stripping out 90% of the billing complexity, and including simplified reporting, and consumption modelling in the digital app experience.

Areas of concern
This is too good to be true: Multiple test subjects said this. Essentially: "Why is an energy retailer trying to be nice to us?" Because this feedback was "positive" we tended to dismiss this sign of customer suspicion. Later testing suggests that this was a mistake.

But what are you doing with my money?: Some users expressed concern that amaysim was holding customer's money in credit. Once again customer suspicion could nullify the benefit of bill smoothing.

By the time this content was added the originally simple plans were looking information dense and daunting to read.
Progressive rounds of simplification
An initial round of simplification used iconography and background colours to reduce word count and improve structure. There was still a lot of repetitive content to read however.

Disappointing sales figures
In the months following the new product launch sales figures were disappointing. There was a clear gap between the consistently positive feedback we had gathered in user testing and the fact that amaysim was selling more post-paid plans than pre-paid ones.
This was compounded by the fact that amaysim was not investing in advertising, or further development of the product.
Modelling the consumer comparison and purchase experience
While validating the most recent designs with remotely recruited test subjects I devised a new test to examine how users compared energy plans.

Testing product rules: Users were quizzed on their response to the product values of simplicity and pricing transparency

Test outcomes
I had assumed that the two prior steps of the test (explaining predatory industry behaviour and demonstrating the value of pre-paid plans) would be heavily prejudicial towards users choosing the amaysim pre-paid plan. Instead, 80% of test subject chose a competing post-paid plan.
The unexpected result could be explained by observed test subject behaviour
1
Simpler product design did not result in a simpler user experience: While pre-paid plans were easier to understand in isolation, it was actually more complicated to compare them against post-paid plans with conventional pricing models.

2
Users took shortcuts to evaluate value: Users were not prepared to do the complex maths to compare complicated plans, instead relying on high level anchor statements, even if they were meaningless or comparing different things. Plan B was perceived as being cheaper than Plan C, when it was actually slightly more expensive.

Users were swayed by acquisition pricing: Users chose "cheaper" prices even when they were warned that sign-up prices for post-paid plans would rise markedly later. Users distrusted the brand and industry too much to believe that pre-paid pricing wouldn't rise later too.

Sixteen months after launching it's pre-paid energy plans amaysim sold its energy arm to AGL. This process had stalled, and then terminated, product development since amaysim had stopped investing in energy 12 months before the deal was announced.
UX learnings
While the amaysim product and design team had ostensibly designed a "better" and "more user friendly" product, commercial results (though complicated by other factors) contradicted this. This was a very important lesson for me.
