As the impacts of climate change intensify globally and emission reduction deadlines loom, Australia must prioritise its power supply.

The 2019–2020 Australian bushfires, which triggered widespread blackouts nationwide, underscore the urgent need for power resilience. These events highlighted the critical necessity for reliable energy sources and robust energy storage solutions for businesses and communities alike. Moreover, they emphasised the importance of integrating renewable energy sources into the national grid to ensure a resilient and sustainable power supply during disruptions.

To do so, we must embrace digital technologies in the energy sector. These advancements not only support growth and sustainability but also enhance the resilience of our energy systems. By making renewable energy more practical and efficient, digital innovations pave the way for a stable and sustainable energy future for Australia. The transition to a digitally enabled, renewable energy infrastructure is not just an option — it is essential for securing our energy needs in the face of ongoing and future challenges.

Renewable progress in Australia

The government has set ambitious targets to expand renewable energy capacity, planning to add substantial wind and solar projects. This demonstrates Australia’s significant progress in adopting renewable energy systems (RES). Australian energy provider Origin Energy has recently demonstrated its strong commitment to renewable energy infrastructure by investing AU$400 million to build a 460 MW battery energy storage system (BESS) at its Victoria peaker plant.

Adopting RES helps drive the reduction of emissions and ensures energy availability. However, renewable energy generation is variable, depending on the fluctuating intensity of the sun and wind. To address this variability, we need grid-scale energy storage. Research indicates that implementing such solutions can help develop resilient grids capable of accommodating high levels of RES.

Long-duration storage

Long-duration energy storage (LDES) remains a significant technical challenge, as storage requirements can vary from hours to months. Pumped-storage hydroelectricity is widely used but holds untapped potential in many regions. Batteries, particularly lithium-ion, are the most scalable form of grid-scale storage due to their modular deployment and availability. Other technologies, like compressed air and gravity storage, play smaller roles in current power systems. Additionally, hydrogen storage holds promise for the seasonal storage of renewable energy.

Emerging technologies, such as flow batteries, also offer potential. Flow batteries use a liquid electrolyte to store electrical charge, scalable and adaptable to the variability of wind and solar generation. According to recent studies by 2040, LDES could deploy between 1.5 and 2.5 terawatts (TW) of power capacity globally, representing a significant increase from current levels.

Microgrid support

LDES can support micro-grid designs for large energy users, such as manufacturing and heavy industry. These facilities can deploy large battery systems, like lithium-ion batteries in intelligent uninterruptible power systems (UPS), to enhance storage capacity and facilitate greater RES adoption. Microgrids offer short-term storage capacity, helping to smooth peak grid usage and address variability concerns. This is especially beneficial for rural deployments and areas where proximity to RES generation is an issue. Microgrids ensure resilience, allowing power to flow even when generation sites are offline due to atmospheric conditions or disruptions.

As Australia moves towards implementing smart national grids, microgrids play a significant role. Large energy users can be rewarded for their storage and resupply capabilities, supporting peak grid usage. These measures can be quickly implemented through economies of scale, reference designs and vendors’ pursuit of efficiency. Organisations can confidently build out capacity while supporting decarbonisation efforts, moving Australia closer to a net zero energy future.

Digital innovation in power

The digitalisation of energy, or Electricity 4.0, is crucial for smart grids, microgrid integration, RES adoption and achieving net zero goals. Digital innovation enhances visibility in energy generation and distribution, eliminating waste and driving efficiency. Technologies like metering and monitoring enable better energy usage, while smart devices, apps, analytics and software allow for more efficient deployment of smart energy. These solutions enable everyone to contribute to a renewable-powered, sustainable energy future.

Renewable energy sources will form a significant part of future energy generation, crucial for achieving a decarbonised, net zero goal. Grid-scale energy storage and its resilience are critical for integrating renewable energy sources into digitised smart grids. Large energy consumers can support this transition by leveraging digitalised energy systems, increasing transparency and underpinning the development of sustainable digital economies accessible to all.

Australia’s renewable energy future depends on the effective integration of energy storage solutions. By embracing digital innovation and scalable storage technologies, we can build resilient and sustainable energy systems that meet our future needs.

Insurance sector digs into impact of mandatory climate reporting

Insurance sector digs into impact of mandatory climate reporting

Businesses are being encouraged to prepare for the impact of mandatory climate disclosure in Australia.

Earlier this year, the federal government passed amendments to the Corporations Act 2001 (Cth) and the Australian Securities and Investments Commission Act 2001 (Cth), resulting in mandatory climate reporting for larger businesses in Australia.

The issue was examined during a recent address to members of the Underwriting Agencies Council, with particular attention paid to how the new legislation will affect the insurance sector.

Speaking at the event, Prateek Vijayvergia, Xceedance Business Leader – Key Accounts, Australia and New Zealand, said that while 75% of ASX 200 companies were committed to or already performing climate reporting, the number fell to 10.5% for broader ASX companies.

“There’s a lot more awareness and commitment and urgency that we see in the Australian market now and this is not limited only to the insurance business, but for all larger Australian businesses,” he said.

“Although this is all good, there is a gap in climate-related reporting among ASX-listed entities, and the depth and the quantification.”

Joining Vijayvergia in the discussion was Sharanjit Paddam, Principal – Climate Analytics at Finity Consulting, who said that from 31 December 2025, in addition to an Annual Report, large companies will need to submit a Sustainability Report — what Paddam referred to as “the home for ESG disclosures”.

Four pillars underpin the disclosure standards — governance, strategy, risk management, and metrics and targets. Paddam emphasised that the devil is in the detail.

“You not only have to disclose the financial impacts on your balance sheet today and your income statement today, but also in the short-, medium- and long-term future,” he said.

“They (ASIC and APRA) want hard numbers to be put in the accounts about how climate change is financially going to affect the operations of the company.”

Paddam explained: “At the heart of the disclosure is really what are the financial impacts of climate change on your company, investors, customers and shareholders; to understand that and to allocate capital and make investment decisions informed by how climate change might affect your business.”

Paddam added that companies need to consider their own impact on climate change.

“The world is changing in disclosures in a very big way over the next few years, and companies are going to have to think about not just accounting for their financial outcomes, but also their climate outcomes,” he said.

“These are mandatory standards — this is locked in, and it will be required to happen over the next few years, and it is intended that these standards will change the economy and they will drive changes throughout the way we do business.”

A particular challenge will be the reporting of Scope 3 emissions — those indirectly generated by the activities of an organisation — due to lack of data, methodology and resources.

“What’s really helping all of us is the advancement in technology so there are better ways of collecting information and data around emissions,” Vijayvergia said.

“And also, to then slice and dice that information so it can be used to make a plan around climate risk.

“It’s becoming more comprehensive and almost integral to the overall reporting that’s happening for an organisation.”

Organisations impacted by these legislative changes include those that produce accounts under the Corporations Act and meet any two of the following criteria: consolidated assets more than $25m; consolidated revenue more than $50m; or 100 or more employees.

Paddam said the new requirements would capture some of the larger underwriting agencies and brokers.

“It’s an opportunity to look at the services that you are providing and how good a partner you are for your insurance provider, or as a distributor of insurance products, to see where you could uplift your services in this respect,” he advised.

“The things we insure, the things we invest in, are all intended to change as a result of these disclosures, and getting your heads around that quicker and faster than your competition is very important.”

High fidelity, publicly available data is essential for mobilizing clean energy investment and informing renewable energy policy and deployment decisions, but access to this data is a critical barrier for many countries aiming to develop and optimize their clean energy resources. Recognizing the importance of tools that offer accessible data to inform renewable energy planning and deployment, the USAID-National Renewable Energy Laboratory (NREL) Partnership developed the Renewable Energy (RE) Data Explorer. RE Data Explorer is a publicly available geospatial analysis tool that provides free global renewable energy resource data to inform policy, investment, and deployment decisions for solar, wind, and other energy resources. 
Two of the thematic days at COP29 are focused on energy and science, technology, innovation, and digitalization. RE Data Explorer is a great example of how digital technologies can play a role in promoting clean energy and addressing the climate crisis. The tool also delivers on the commitment USAID made at COP28 to make investments that will “support technical assistance programs and partnerships to strengthen subnational climate preparedness.”
The use of USAID-NREL public data in Tanzania, available on RE Data Explorer, offers a direct example of the impact of accessible data on the implementation of renewable energy projects. Tanzania is working to accelerate the deployment of renewable energy and decarbonize its grid, aiming for 30-35 percent emissions reduction by 2030. A major challenge to pursuing this goal is the lack of reliable, long-term renewable energy resource data for project planning.
NextGen Solar, a private sector partner of USAID Power Africa, used USAID-NREL data specific to Tanzania to support the development of its renewable energy projects in the country. The company, which specializes in building and operating utility-scale solar photovoltaic (PV) power plants in sub-Saharan Africa and small island nations, utilized USAID-NREL public data to develop the world’s largest PV-hybrid solar mini grid in rural Kigoma, Tanzania. USAID-NREL public data enabled NextGen Solar to perform technical feasibility studies to forecast electricity generation in an area previously lacking reliable, affordable power. Thanks to this reliable data and analysis, NextGen Solar was able to mobilize $6 million in investment to build the plant. This 5-megawatt (MW) plant has now been in commercial operation for over 3.5 years and supplies electricity to over 65,000 homes, the region’s largest hospital, and three schools. It has also helped the Government of Tanzania save an estimated $2.2 million annually while reducing carbon emissions and demonstrating the viability of utility-scale solar power to sub-Saharan Africa.
The application of USAID-NREL public data in Ukraine is  another example of how open data can drive the mobilization of clean energy projects. Planners and developers in Ukraine are looking to incorporate more renewable energy, particularly wind and solar, as the country rebuilds its grid and searches for new means to become less dependent on foreign resources. Like Tanzania, a barrier for Ukraine was the lack of accessible, high-quality data on its wind and solar output capabilities. USAID-NREL is helping Ukraine overcome this barrier through new high-resolution solar time series data accessible on RE Data Explorer, which will help Ukraine meet the needs of stakeholders in the energy sector across the national government, academia, and private industry.
“[USAID-NREL public data] really helps with planning and understanding where the resources are—where it is most cost effective to build distributed resources that will help to decentralize the grid.”
NREL’s Ukraine program lead, Ilya Chernyakhovskiy

To better understand the broad impact of RE Data Explorer, a 2024 NREL survey gathered insights from respondents on how they applied this data in real-world scenarios. Overall, respondents reported evaluating and planning over 111,000 MWs of solar and wind projects, with a potential investment of over $6.5 billion. End-users also reported over 1,600 MWs of solar and wind energy with over $1 billion  in investment that has been approved and financed. For context, according to the Solar Energy Industries Association (SEIA), 1,600 MWs would power approximately 275,200 average U.S. homes and 111,000 MWs would power approximately 19.1 million.
One particular real-world example provided by the survey came from a respondent from climate tech startup Ureca who shared that their company pursued a .3MW solar project in Mongolia that was approved and financed. Ureca’s project “focuses on small PV systems for households in Mongolia that currently use raw coal for heating.” This initiative, called Coal-to-Solar, is now helping low-income families transition from coal to renewable energy in Ulaanbaatar, Mongolia—the coldest capital in the world—as part of a Just Energy Transition pilot aimed at reducing reliance on coal.
The outcomes of these projects also highlight how USAID and NREL are working together to implement USAID’s 2022-2030 Climate Strategy. In accordance with the plan’s strategic objective, “Targeted Direct Action: Accelerate and scale targeted climate actions,” projects informed by USAID-NREL public data in Tanzania, Ukraine, and Mongolia employed context-sensitive approaches to “support climate change mitigation and adaptation efforts in critical geographies, [and] mobilize increased finance.” Furthermore, USAID and NREL’s work focused on accessible data supported Intermediate Result 1.1 in the plan, which aims to “catalyze urgent mitigation (emissions reductions and sequestration) from energy, land use, and other key sources.” 
From accelerating Tanzania’s clean energy transition, to aiding Ukraine’s rebuilding efforts, to enabling clean energy projects across the world, USAID-NREL public data is helping users and local communities reduce greenhouse gas emissions, promote sustainable development, and pave the way for a cleaner, more resilient future.
