Why Synergy?

Synergy is the largest electricity supplier in Western Australia. In addition to having significant power generation capacity, they also retail gas to business customers. So far they have serviced over a million people in Western Australia.

Synergy is a state-owned enterprise, meaning that the Western Australian government and the Western Australian taxpayer, are its owners. This also makes the company 100% Australian owned and operated.

Supply Area

Synergy operates along Western Australia’s South-West Interconnected System (SWIS). This network extends from Kalbarri in the north, to Kalgoorlie in the east, and down south in Albany. When you add in Perth, you’ll find Synergy retails electricity to over 50% of Western Australians.

Whether you’re a homeowner or a small business owner, you have to use Synergy for an electricity connection. They also service large industrial customers as well.

Synergy’s Dominance

Synergy currently supplies customers in WA who are in the SWIS (South West Interconnected System). The SWIS represents the zone in WA with the most population. Synergy has been granted a monopoly on selling electricity to residential and other small-scale business customers who do not consume a lot of power. The company also sells gas to large-scale customers such as industries. Large scale businesses that use over 50,000 kWh a year in power, however, can choose another electricity retailer if they want to. Small-scale users in the SWIS region, however, are termed “non-contestable customers” and can only get their power from Synergy.

The company’s government-backed monopoly may possibly end in the future, however, as the call for full competition grows louder. Opening up the SWIS region for more competition was a fundamental reform put forward by a 2016 review of the wholesale electricity market by the Economic Regulation Authority. It has been maintained that more competition will bring prices down and help customers in WA. The benefits of state-owned power generation cannot be understated in any manner. Regulation of gas prices in WA has made gas affordable and available for gas customers in remote regional locations. To do this, WA state governments have had a subsidy in place for a few years. It remains to be seen if private competition will be able to maintain the gains for those customers in regional WA in remote, hard to access quarters of the state.

As of now, however, the monopoly Synergy and other WA government-run companies have remains, as the state government seemingly drags its feet on plans for full retail competition. Energy minister Ben Wyatt justified the decision by claiming that it is still up in the air if the retail competition has delivered benefits for customers in the east coast of Australia.

Synergy was born of the West Australian energy reforms in 2006. Initially, West Australian energy was wholly controlled by the State Energy Commission, which later split into Alinta and the Western Power Corporation. The 2006 reforms divided the Western Power Corporation into four new companies, two of which were Verve Energy (a generator) and Synergy (a retailer).

Eight years later, Synergy and Verve merged into one company, also called Synergy. Synergy today has the capabilities to both generate and sell retail electricity in Western Australia. In 2015, a new round of government reviews saw Synergy given the green light to also retail gas to Western Australians, solidifying their stable position in the market.

  • Pay smaller amounts to avoid bill shock

Synergy's generation capacity is ever growing. They have power stations dotted all around the state, but the major ones are:

  • Collie Power Station
  • Kwinana Power Station
  • Cockburn Power Station
  • Pinjar Power Station

They’re also dipping their toes in the renewables field. They own and operate multiple wind farms located in Albany, Coral Bay, Esperance, Hopetown and elsewhere. Synergy recently bankrolled the setting up of a community solar project that makes use of the solar battery technology for home developed by U.S.-based Tesla Inc. The project envisions pooling the solar energy produced by the panels of over 50 homes into a battery bank. In evenings, when the sun goes down, and peak demand for electricity arises as people return home from work, houses can draw upon the battery bank to power their homes. Thus, they do not have to depend on the grid during those times of the day where peak demand also sends prices for electricity higher. As a solar home battery remains an expensive item of spending for most homes in WA, the main benefit of such a community project is that homes experience the benefits of battery storage while not having to spend too much of their money in setting up. Homeowners can instead make payments in instalments, by merely paying a dollar a day for two years.

Adapting to Solar

As the go-to provider for over a million WA customers, Synergy has long experienced strong revenue growth and profit numbers. The situation arose as there were no solid alternatives to the company in WA for most residential customers and small and medium enterprises. All of that changed in 2018 when the company reported a near 6% fall in electricity sales for the year. As a result, for the first time in 5 years, the company’s total revenue fell below the $3 billion mark. The interesting thing was that Synergy generated 10% less electricity in 2018 compared to the same period a year ago.

So why were Synergy sales falling and why did their total generation fall? There appear to be two reasons. Partly it’s due to a taxpayer-funded subsidy slowly getting eroded, which gradually ate away at Synergy’s bottom line. The primary factor, however, is the accelerated uptake in rooftop solar panels across Western Australia. As the subsidies died down, the price of electricity in WA skyrocketed, leading WA homeowners to start seriously considering solar panels. With more homes in WA turning to the panels on their rooftop to give them the electricity they require, they depend less on power from the grid. Thus, the revenue for Synergy has slowly been disrupted by the massive uptake of solar energy in homes across WA.

On top of that, a relatively new gas-fired plant owned by Synergy has had to shut down for extended periods over the past year. According to company executives, the gas plant has been unable to keep up with transitions in supply, as solar energy from WA homes floods the power grid. With over a quarter of households in WA adopting rooftop solar, and more panels coming online, the rise of solar looks unstoppable.

Synergy Chair Robert Cole has said that rooftop solar is now supplying “7% of total SWIS region demand”. Previous state governments in WA have limited large-scale renewable projects, however, the coming years promise increased renewable generation. Moreover, as electricity prices keep rising, it is expected that more homes in WA will turn to solar panels to ease the pressure on their wallet. As a result of these developments in the WA energy scene, Synergy has been ramping up efforts to transform their business.

The first step in the direction toward solar energy by Synergy is through its new solar and battery installation arm named SolarReturn. The company claims to have completed the installation of over 1000 solar systems in WA homes as of 2018, since beginning operation in 2016.
