According to the "System Security Transition Plan 2025" released by the Australian Energy Market Operator (AEMO), the Australian National Electricity Market (NEM) is facing fundamental changes as solar photovoltaic (PV) power and battery energy storage systems (BESS) drive Australia's transition to a low-emission energy system.   AEMO CEO Daniel Westerman stated that this plan is "the most comprehensive plan to meet NEM system security requirements and consumer needs" at a time when Australia's energy system is rapidly changing due to the retirement of coal-fired power plants and the replacement by renewable energy, energy storage, and gas turbines.   The report indicates that rooftop PV capacity will increase from 25.1 GW in 2026 to 42.5 GW in 2036, while non-dispatchable PV capacity between 100 kW and 30 MW will increase from 1.9 GW to 4.8 GW during the same period.   This growth reflects the rapid adoption of distributed energy resources (DERs) by Australian households and businesses, driven by factors including policy incentives, declining technology costs, and consumer demand for energy independence.   Westerman emphasized that Australian consumers continue to invest in rooftop solar at a "world-leading pace," and are now adding residential battery storage systems and electric vehicles (EVs) to their energy systems.   However, the increasing adoption of solar photovoltaic (PV) presents challenges to grid management, particularly due to the volatility of solar power generation during peak hours and its rapid decline in the evening.   The Necessity of Grid-Based Inverters With the increasing adoption of renewable energy, battery storage systems equipped with grid-based inverters have become a key component for maintaining system stability.   AEMO states that NEM currently operates 10 grid-based battery storage sites with a total installed capacity of 1070 MW, while its development pipeline includes 94 projects, comprising 78 stand-alone battery systems and 16 hybrid systems.   Grid-based technologies provide essential system services, including synthetic inertia, system strength, and frequency control capabilities traditionally provided by synchronous generators.   AEMO's analysis highlights the importance of grid-based inverters in stabilizing the grid, although current technologies contribute less to fault current than synchronous generators.   This limitation underscores the necessity for continuous technological advancements to fully replace traditional power generation capacity.   As coal-fired power plants retire, the transition to high renewable energy penetration presents challenges in maintaining system strength and inertia. AEMO has identified eight key transition points related to coal-fired power plant retirement, requiring targeted investments in system strength solutions.   The 1680MW Gladstone coal-fired power plant, scheduled for decommissioning in 2029, exemplifies th...

The average price of a solar power purchase agreement (PPA) in Europe in the third quarter of 2025 fell to €34.25/MWh (US$40.05).   This is according to the latest report from analyst LevelTen Energy, and reflects a decline of 3% between the second and third quarters of this year. Average European solar PPA prices have now fallen 19.4% compared with the third quarter of 2024.   Average solar PPA prices remain lower than those for other technologies—the average wind PPA price sat at €52.75/MWh in the third quarter, a 1.4% quarter-on-quarter increase, while blended PPA prices fell 1$% to €35.55—and fell at a faster rate over the last 12 months than either wind or hybrid deals.   LevelTen concludes that “the increase in solar price cannibalisation” in several European countries is decreasing the perceived value of standalone solar assets, while making investors more likely to support projects co-located with battery energy storage systems (BESS).   Andrés Acosta, director of innovation in Europe at LevelTen, told as much last quarter, when the same trend emerged. In its third quarter report, the company notes that there has been a “surge” in hybrid PPA deals in Europe, combining both solar and wind with BESS, suggesting that investors are more interested in the presence of storage components, rather than the type of renewable electricity generation, when making investment decisions.   Iberian blackout and data centre demands drive changes The report also highlights considerable regional and national variety across the European solar PPA space, with the average cost of a solar PPA signed in the third quarter ranging from €120.00/MWh in Ireland to €33.46/MWh in Portugal.   The average price of a solar PPA signed in Portugal fell -€2.16/MWh between the second and third quarters of this year—equivalent to a 6.1% decline—surpassing Spain, which had the cheapest solar PPAs in Europe last quarter.   Both countries have seen among the greatest percentage changes in average solar PPA price over the last 12 months. Between the third quarter of 2024 and the third quarter of 2025, the average solar PPA price signed in Spain fell 14.1%, while the average price in Portugal fell 16.3%, the third- and fourth-highest rates of decline across Europe, respectively. This reflects growing uncertainty in both markets following the blackout that rocked both countries’ grids in April this year, for which over-voltage has been pinpointed as the primary cause.   The graph above shows average solar PPA prices and quarter-on-quarter changes for 11 European countries. The LevelTen report notes that, while several countries have seen quarter-on-quarter and even year-on-year price declines, the growth of data centres in a number of European countries has helped drive up demand and prices for clean power.   The report points to Ireland, which has t...

The facility will occupy 803 hectares of a 1,475-hectare site, approximately 7km east of Rappville, which has a strong history as a timber and beef town.   In March 2025, Ark Energy signed a supply agreement with Seoul-headquartered Hanwha Energy for the BESS technology. The company confirmed it will use lithium iron phosphate (LFP) technology for the BESS.   The company also executed an Early Contractor Involvement agreement with Elecnor Australia in September 2025 to undertake preliminary engineering and design work. The scope includes site studies, detailed engineering design for the solar PV power plant, and balance of plant design for the battery system, with completion expected by Q2 2026.   The project’s 730,000 bifacial solar modules will feature single-axis tracking technology to maximise energy generation throughout the day. The co-located battery system will provide grid services across the National Electricity Market (NEM), including frequency regulation and peak demand management.   Ark Energy received the planning approval last week (16 October) following inclusion of the project in the Federal government’s inaugural Renewable Energy Priority List in March 2025. The Priority List aims to streamline regulatory approvals for significant renewable energy developments and included over 6GW of energy storage.   This article first appeared on Energy-Storage.news as the item ‘Ark Energy bags state approval for 3.1GWh Richmond Valley solar-plus-storage site in Australia’.   GPG advances 290MW Fraser Coast solar-plus-storage project in Queensland In other news, Global Power Generati...
