Moyhall Solar Farm built by Terregra in SA.

Indonesia’s Terregra Renewables is set to construct a second solar farm in South Australia – with the Moyhall Solar Farm to commence construction in March for an August 2019 completion date.

Terregra and the Moyhall Solar Farm

Indonesian renewable company Terregra are set to construct a second solar farm in South Australia – with the Moyhall Solar Farm set to join the previously announced Mobilong solar farm as Terregra’s second Australian solar project. 

According to their official website, Terregra Renewables are hoping to have 300MW of operating renewable power by 2023. They work on delivering off grid solar power to Indonesia’s remote arreas, and they are also create energy on a utility scale for urban/industrial areas. 

“The Moyhall Solar Farm is another addition to Terregra’s growing pipeline of solar projects,” Graham Pearson, Director of Terregra Renewables, told PV Magazine Australia.

The 5MW Moyhall Solar Farm will include 16,000 PV modules and two inverters, installed inside containers. According to PV Magazine, the $16m Terregra has invested in South Australian solar will create approximately 80 jobs during the constructions of the Moyhall Solar Farm and the Mobilong Solar Farm. These ‘smaller’ type utility-scale investments are often very interesting for investors so Terregra shouldn’t have much trouble finding interest in the solar farms. The Mobilong Solar Farm has appointed Balance Utility Solutions to carry out EPC work on the farm, according to PV Magazine

“Balance is delighted to be working with Terregra Renewables on the delivery of their first solar project in Australia,” said Rod Hayes, Managing Director of Balance Utility Solutions.

“We expect this approach of close developer and EPC early collaboration, and a focus on portfolios of smaller scale projects, to be a growing trend through the next few years as the utility scale solar market continues to mature.”

SA Minister for Energy and Mining Dan van Holst Pellekaan discussed the impact Terregra’s investment will have on the community:

“Terregra Renewables’ $7.6 million investment will increase South Australia’s energy supply, stimulate the local economy and create local jobs,” said Minister van Holst Pellekaan.

Mannum Solar Farm Greenlit | Murraylands Solar

The 5MW Mannum Solar Farm in the Murraylands will be built by Tetris Energy, and has been approved by the local government. 

Mannum Solar Farm

The Mannum Solar Farm will be 5MW in size, generated by 17,500 solar panels. It will also include a security fence and vegetation screen to ensure neighbouring property owners aren’t disturbed (sometimes we hear about glint and glare when there is solar farm opposition). The farm will be across the road from the Rivapak onion packaging facility. 

An article in the Murray Valley Standard noted that over 8000 households in the Murraylands area have solar panels installed on the roof of their properties – so it’s an amazing area which shows that South Australian solar is continuing to grow domestically and commercially.

Tetris Energy, based in Melbourne, will develop the site. They have already successfully developed 10 solar and wind power plants across Australia so they have a good pedigree – and they have also already secured a purchaser of all 5MW of the power (not named) – but this is obviously a fantastic boost for the farm and will ensure it gets built quickly. The proposal had been approved last April, but had the number of solar panels slightly reduced (in the November application) so they don’t overshadow each other. 

Murraylands Solar Farms

There are already three other solar farms in the Murraylands area:

Clean Energy Council chief executive Kane Thornton discussed solar uptake in the Murraylands in the Murray Valley Standard:

“Homes with rooftop solar installed are saving an average of about $540 per year on their electricity bills,” he said.

“Solar is a clear way for consumers to take control of their power consumption and cut costs, and it’s growing quickly by word of mouth.” Mr. Thornton continued.

SolarReserve sign MOU for Aurora Project

American company SolarReserve have signed an MoU with Heliostat SA to manufacture and assemble the components for their solar tower and molten salt storage facility at Port Augusta.

SolarReserve Commence Construction on Aurora Solar Thermal Plant

SolarReserve announced on Tuesday that they’ll work with Heliostat SA to create 12,800 96 square metre glass mirrors for their Aurora Solar Thermal Plant. 

The solar thermal plant in Port Augusta, South Australia, was announced last August and received developmental approval back in January It is slated to be a $750m project but we haven’t heard any specifics as to updated pricing, and this information is the first news on the project since January of this year. 

According to the CEO of SolarReserve, Kevin Smith, the solar thermal power plant will comprise of approximately 12,000 mirrors, each the size of a billboard (around 100sqm), arranged in a circle over 600 hectares. The mirrors will focus light and heat to the top of a 227m tall tower to generate up to 150MW. This will result in over a million square metres of surface area for the project. 

“Aurora will provide much needed capacity and firm energy delivery into the South Australian market to reduce price volatility,” Mr. Smith said at the time. He elaborated today when discussing the deal with Heliostat SA: 

“We’re excited to have formed a long-term partnership with Heliostat SA and look forward to teaming up with them to bring manufacturing of our world-class heliostats to South Australian workers,” said Mr. Smith.

“SolarReserve is committed to supporting South Australia’s goals which will attract investment, create South Australian jobs and build an exciting and growing new industry.”

According to an article on RenewEconomy the project will create around 200 full time solar jobs for the area, with 650 to be employed during the construction phase. 

This project is a bit slow and new information is thin on the ground, so great to hear that it’s moving ahead. We’ll keep you posted as soon as there’s any new information on the solar thermal plant!

Hornsdale Power Reserve saves $8.9m in 6months

Hornsdale Power Reserve – also known as the Tesla South Australia battery, the 129MWh solar/energy storage battery has saved the state $8.9m in six months, according to Renew Economy and their analysis of spot market pricing in 2018.

The cost of the Hornsdale Power Reserve hasn’t been made public, but at ~$800 per installed kWh the cost comes out to around $100m (with around $50m paid by the government), which fits the whispers we’re hearing around the traps.

The partnership between Tesla and South Australia was inked in July last year as Elon Musk and then-Premier Jay Weatherill decided on Neoen’s Hornsdale wind farm as an installation spot. The Tesla Battery was then completed on November 24, ahead of its December 1 operation deadline (Musk made a bet with Weatherill/South Australia that Tesla would install the Powerpack batteries by December 1 or the project would be free).

According to an analysis undertaken by RenewEconomy and investigated further by Clean Technica, The battery saved $5.7m in its second quarter of operation. It bought power at an average price of $79/MWh and sells it at $191/MWh (a figure somewhat distorted by a very power-hungry January – with that month removed the price goes down to $141/MWh). The estimated savings for the full 2018 are expected to be around $18m. 

It’s important to note that the battery is still trading 30MW (of its total 100MW) of capacity so there is space to expand operations should the government be so inclined.

South Australian Virtual Power Plant Launched

Tesla’s South Australian Virtual Power Plant has begun deployment, with the first 100 Powerwalls combined with a 5kW solar array rolling out across a group of South Australian households this month. This rollout is in conjunction with the Household Storage Subsidy Scheme in South Australia.

Housing SA are working with Tesla to install the distributed Powerwall tech which is going to start with a focus on public housing and will end up with arrays and Powerwalls/other batteries (read on to learn about the Household Storage Subsidy Scheme) on up to 50,000 homes. 

Another 1,000 South Australian households will have the Tesla batteries installed before July 2019, but potentially ‘in a few weeks’, according to Electrek. Lots of different figures floating around right now so we’ll update you as we hear more.

It’s actually quite similar to the 100MW / 129MWh Powerpack project in that the whole system will help stabilise the grid and provide a strong baseload of power so we don’t see the blackout issues South Australia suffered through in 2016. In this case it’s not one big project, however – many homes working together will decrease cost of electricity and ensure grid stability improves (and continues to). 

There’s also a separate scheme for other battery subsidies – underwritten by the $100 million Household Storage Subsidy Scheme. The push to help renters and low-income earners enjoy the benefits of solar has been fantastic and we’re excited to see some stats and results after the estimated 40,000 SA households receive on average $2,500 each. Please note that this particular scheme is for people who already have solar power installed and want energy storage as well and is not related to the Tesla virtual power plant.

You can watch a video Tesla released about the South Australian Virtual Power Plant – it’ll explain what the plan is and what we can expect to see next from SA and Tesla!

There’s also a video on Twitter from Nine News Adelaide where the current (Liberal) SA state government seem happy to take credit for this scheme (which was totally organised under the previous (Labor) government). Bit of an eye-roll, but then again it’s par for the course for our beloved Australian politicians.

Regardless of that, the tenant in this video had a $500+ bill for electricity every quarter, which has been reduced to $175 since having the solar system installed. So those are some fantastic numbers!
