Compare Power Companies: 5 Things To Consider

To get the best power deals, you need to shop around. And while price is a go-to measure of value, it’s not all there is to consider. So if you’re looking to compare power companies, Canstar runs through the five things you should consider.

When you compare power companies, it’s important to consider more than just price. Instead, it’s best to consider the whole package offered by a provider.

For while cost is hugely important, you also need great customer service and support when needed. You might also prefer a power company that focuses on renewable energy, or one that provides additional benefits, such as rewards points.

To help you make the right choice for your personal needs and preferences, Canstar Blue offers the following guide on what to think about when you compare power companies.

Electricity Perks

1. Price

When we compare power companies, price is the thing that comes to mind first. And it’s understandable. No one wants to overpay. But, unless there’s a drastic difference in price, then you may be better off comparing power companies on what other benefits they offer.

Sometimes paying a bit more is worth it if you know you’ll receive great customer service. Also, consider what else you get for your money. Maybe one retailer is offering extra incentives, such as signing on gifts, cash credits, or a daily free hour of power.

It’s also worth looking at the full suite of off-peak and peak rates offered by power providers. Some electricity retailers charge slightly higher prices for their peak power, but give considerable discounts on their off-peak night, daytime and weekend rates.

So when choosing a power company, make sure you know the times when your household consumes the most power. This will help you make a more informed comparison of per kWh prices.

2. Customer Service

Most power companies try to position themselves as champions of great customer service. And some rightly so.

But while you might think customer service is less important than price, think about the last time you had to call your provider and how that call went. If a company offers no-frills prices, this could be reflected in its level of customer service.

And, nowadays, customer service is about more than not being left on hold on the telephone for half an hour. For example, does your energy provider have a social media page where it can be reached? Does it respond to emails? And how easy is it to contact the company through its website or app?

Furthermore, is your power company proactive? Do they let you know about upcoming deals, new plans, or if you’re on the right plan for your power usage?

To see how your power company compares on customer service, check out our Star Ratings. Every year we canvass hundreds of Kiwi electricity consumers and ask them to rate their power companies for customer service, value for money and overall satisfaction.

3. Helpful tools

As the energy industry becomes more innovative, some retailers are focusing their efforts on tools to help people make better decisions about their energy usage. These tools include apps that report energy usage in close to real-time, guides on the running costs of appliances, and even platforms that give customers the chance to compare providers’ prices.

Being able to pay bills, check past usage or project future usage, update your details, and more, all from your phone is a huge benefit.

4. Suitability

The best deal isn’t simply the one that’s best on paper. It’s the one that best suits you and your power needs.

For example, if you’re price conscious or on a budget, a simple, no-nonsense plan may be best – one that cuts the extras and just gives you fixed low rates that provide bill certainty.

Or, if you’re a night owl or charge an electric car overnight, perhaps you’d be better off with a plan with discounted late-night rates, even if that means higher rates during the day.

5. Renewable Energy

We’ve left this one until last because, although important, it’s a little complex.

The largest share of New Zealand’s energy comes from clean, green, hydropower. It accounts for well over half of all the electricity produced in the country.

Throw geothermal, wind and even a little solar into the mix and around 85% of all power generated in New Zealand comes from renewable sources. So you can be pretty confident that most of the time you’re keeping the lights on and your new EV charged with clean energy.

But while NZ has a good renewable energy profile, around 15% of power still comes from fossil fuels. And, unfortunately, you don’t get much say in whether the power you use is 100% renewable or not.

New Zealand has five electricity gentailers (companies that both generate and sell electricity):

  • Contact
  • Genesis
  • Mercury
  • Meridian
  • Trustpower

The electricity generated by these companies is distributed collectively on the national grid. This means all power generated is mixed together, regardless of whether it came from hydro or coal. Energy is then bought from the national grid (by a power company) and sold to you. So, simply signing up for a power company that only uses renewable energy isn’t really an option. Even the five companies listed above must sell their power to the national grid before then buying it back off the grid.

However, if your power provider is one of the five listed above, you can factor in how that company generates its electricity, even if the power you’re using is a blend coming from all five.

Currently, Meridian and Mercury are the only two companies generating 100% renewable energy. As for the rest, there are varying degrees of fossil fuels in the mix. Looking at each company’s sustainability practices and commitments could be a good idea.

If your power provider isn’t one of the five listed above, then it doesn’t generate any electricity. It simply buys it from the national grid and sells it to you. So while you can’t judge them on how they generate electricity, you could always look at how the company operates and its sustainability practices as a whole.
