Empowering Communities: The Rise of Microgrid Solar Power Systems

In a world seeking sustainable and decentralized energy solutions, microgrid solar power systems have emerged as a beacon of hope, revolutionising the way communities generate, store, and consume electricity. A recent article published by The New York Times on August 7, 2023, titled “Microgrid Solar Power: Paving the Way for Energy Independence,” sheds light on the transformative potential of these innovative energy networks.

According to the New York Times, “Microgrid solar power systems represent a paradigm shift in how we think about energy generation and distribution. These localized systems are changing the landscape of power generation, making communities more resilient and environmentally responsible.”

The article delves into the intricate workings of microgrid solar power systems and their remarkable ability to provide localized, resilient, and environmentally-friendly energy solutions. As global concerns about climate change and the depletion of finite fossil fuels intensify, the spotlight is increasingly turning towards renewable energy sources, and microgrids are stepping into the limelight as a promising solution.

More about Microgrids

At the heart of the microgrid concept lies its capacity to generate electricity on a small scale, catering to specific community needs. Dr. Emily Rodriguez, an energy expert interviewed for the article, explains that “Microgrids empower communities by allowing them to take control of their energy production. This localized approach not only reduces transmission losses but also enhances energy security and helps mitigate the impacts of climate change.”

One of the most remarkable aspects highlighted by The New York Times article is the resilience that microgrid solar power systems offer. In an era marked by unpredictable weather events and natural disasters, these systems serve as energy lifelines, providing uninterrupted power to critical facilities such as hospitals, emergency shelters, and communication centers. The New York Times quotes Mark Johnson, CEO of a leading microgrid solutions provider, saying, “Microgrids are the future of reliable energy supply. By incorporating energy storage technologies, these systems ensure a constant power supply, even during disruptions.”

Furthermore, the article highlights the economic benefits of microgrid solar power systems for communities. As energy costs continue to fluctuate, and concerns about energy security persist, many communities are embracing the microgrid model as a means of reducing their reliance on traditional utility companies. According to the article, “Microgrids not only offer energy resilience but also stimulate local economies. Job creation in the renewable energy sector and reduced energy expenses are just some of the positive outcomes observed in communities adopting microgrids.”

The potential for microgrid solar power systems is vast, and the article underscores ongoing initiatives and projects that are already making waves across the United States. For example, the Brooklyn Microgrid is highlighted as a pioneering project that allows residents to buy and sell excess energy generated by their solar panels within the community. This innovative approach not only promotes sustainable energy practices but also empowers local residents to become active participants in the energy market.

In conclusion, the recent article by The New York Times serves as a rallying cry for the widespread adoption of microgrid solar power systems. As we navigate the challenges of the 21st century, it is imperative that we explore sustainable, adaptable, and resilient energy solutions. Microgrids, with their ability to generate clean energy at a local level, hold the key to a future powered by the sun, harnessed by communities, and safeguarded against the uncertainties of the modern world.

280kWh Redflow-based microgrid in Tasmania

Redflow CEO Simon Hackett has installed a 280kWh Redflow-based rural microgrid in Tasmania. The sheep farm will benefit greatly from the ZMB2 flow batteries – let’s take a look at the install and how it’s going to work.

The 280kWh Redflow-based rural microgrid is now live according to a press release on the Redflow website. Simon Hackett’s place, a sheep farm named the Vale, has seen install of 280kWh of  Redflow ZBM2 zinc-bromine flow batteries. We first wrote about this Redflow microgrid in 2019 – fantastic to see the Vale’s solar installation improve and upgrade along with solar panel technology.

The Vale (http://www.thevale.com.au), a working sheep farm with the largest private runway in Tasmania, is a 73-hectare property including a number of farm buildings and multiple houses.

The solar install uses a cluster of 12 x 15KVA Victron Quattro inverter/chargers and control systems that can deliver a peak energy output of 180KVA – it’s wired throughout the property to create the microgrid. The solar energy created by the ground-mounted 100kWp solar array is stored in 28 Redflow 10kWh ZBM2 zinc-bromine flow batteries, for a total storage capacity of 280 kWh. 

Hackett went on to discuss some of the specifics of his microgrid in Tasmania:

“The battery array makes extensive use of the Redflow Standby Power System (SPS) mode, allowing batteries to be fully charged during good solar weather days, and to then be ‘hibernated’ with zero self-discharge. During extended overcast periods, the SPS batteries are automatically activated to support site loads instead of using the grid. This unique strength of Redflow’s ZBM2 batteries allows the site to maximise both energy storage quantity and also energy storage efficiency.”

Hackett, who also works as Redflow’s Systems Integration Architect, said the system will completely eliminate grid electricity costs for the property. “The system also gives us energy resilience by automatically switching to off-grid mode during any grid power failures,” he said.

The 24 month trial period means that customers participating will be able to ‘virtually’ store excess power they generate during the day (it’ll be fed into the utility-scale 105kW Tesla PowerPack Battery). They can then use 8kWhs of the PowerBank’s battery storage without needing to install their own power bank. According to the press release (and it’s true!), “8kWhs is enough to power the average suburban home for over one hour during peak time.”

Energy Minister Ben Wyatt discussed the Tesla PowerBank trial in a series of interesting quotes which explain how helpful this trial could be to Mandurah residents:

“PowerBank is an ‘in front of the meter’ storage trial which allows invited local customers to store excess electricity from already installed solar PV systems to then use it during peak times.

“This is another Australian milestone for the application of utility-scale batteries for the benefit for customers, drawing on the groundbreaking work by Synergy in its Alkimos Beach energy storage trial.

“For the first time in Australia, a utility-scale battery will be integrated into an established suburb’s network, like Meadow Springs, that has a high level of existing solar PV uptake.

“At the cost of one dollar a day, customers will have access to 8kWh of battery storage to use any time after 3pm each day.

“This trial shows that the WA Government is serious about working with renewables, delivering for taxpayers and planning for our energy future.”

Victorian home owners who fit the criteria (it’s means tested) will get a 50% rebate to install battery storage. The rebate will be capped at $4838 in the first year and will slowly decrease to $3714 by 2026, factoring in the inevitability that prices will decrease and energy storage technology will improve. The Age are reporting that this policy will cost an estimated $40m, with around 10,000 Victorian households expected to take advantage of the fantastic subsidy offer. 

According to the SBS, it’s part of Labor’s wider plan to increase renewable energy use and decrease the cost of living – with the plan being to work with energy distributors and invest $10m to help ‘renewable-proof’ the state grid over the next ten years. 

“This is a game changer for Victorian families fed up with big corporations that have been price gouging and ripping consumers off,” Premier Daniel Andrews said.

“Only Labor will put solar panels, solar hot water or solar batteries on 720,000 homes – saving Victorians thousands of dollars on their electricity bills with renewable energy.”

Solar Homes Victoria Subsidy Breakdown

We’ve previously written about Labor’s half price solar for Victorians scheme- looks like there are some great plans coming to fruition for the state. 

Solar Panels – $1.2b for 50% of solar system installation costs for 650,000 homes.

Solar Hot Water – $60m for $1000 subsiddies to install solar hot water.

Solar Batteries – $40m for 50% of solar battery installation costs for ~10,000 homes.

It’ll be very interesting to see how these solar battery rebates work in Victoria and if the other states (especially the ones with a high solar panel update) follow suit. Watch this space – we’ll keep you updated!

Euroa microgrid: community solar to avoid summer blackouts.

The Euroa Environment Group is leading a $6 million grassroots project which will see 589 kW of new solar panels and up to 400 kW of energy storage installed to create a local Euroa microgrid. This will help avoid the summer blackouts which have plagued the small north-east Victoria city in recent years.

The EEG (Euroa Environment Group) is a local collective formed to help the issue of constant blackouts in the small city. They’ve now got a huge $6m project which will see the EEG partner with Mondo Power, Globird Energy, and 14 local businesses in Euroa who will install the technology, creating a microgrid in the city which means the town will have greater electricity supply reliability, and will also reduce local demand for electricity during peak times.

The Andrews Labor Government has also given a $600,000 solar grant towards the project, which is currently underway.

Shirley Saywell, president of the EEG and local business owner, has discussed the reasons they’ve taken this path:

“We believe that unfortunately we’re not getting good leadership from our Federal politicians, and I believe it’s up to grassroots organisations to drive the renewables charge,” she said.

“There’s no one simple answer to coal, and I think that’s not well understood.”

“Leadership is coming from groups like ours because we understand there is a range of solutions, and there’s not one simple solution. It’s about being clever about what’s available to us.”

 This sort of community solar is also a hot topic of discussion for Australia’s politicians:

Jaclyn Symes, Member for Northern Victoria, discussed how this could impact future decisions for other towns suffering from unreliable power supply:

“Everyone is becoming more educated around the opportunities and the options for reducing reliance on coal,” Ms Symes said.

“I expect that lots of people will be watching with interest about how this works and what savings people will see, and what types of reliability of power improvements can be generated as well.”

We’ll keep you updated with any news from this microgrid and how it helps Euroa traverse the 18/19 summer.
