How long is the ‘Golden time of day’ for batteries?
A key part of the business case for grid-scale standalone batteries is the arbitrage opportunity between low daytime wholesale prices (when renewable energy generation from solar is plentiful) and high evening prices (when the sun goes down and household demand ramps up quickly). The share of battery revenue coming from...
Spread your wings and arbitrage away as Q2 sees ‘the spread’ increase
The focus of batteries is constantly adjusting to reflect ‘where the money is at’. Various quarters have trends, and others have events that swing momentum. With FCAS enablement in Q2 this year dropping to some of the lowest values since 2016, shifting the solar curve, or rather arbitrage, became the...
Proposed changes to PFR and the impact on battery operations
On 3 August, at the request of the Australian Energy Market Operator (AEMO), the Australian Energy Market Commission (AEMC) initiated a rule change request proposing to “clarify the mandatory primary frequency response (PFR) obligations of scheduled bidirectional plant (i.e. batteries with a capacity of 5MW and greater)”. One of the...
The Australia-Asia power line proposed by Sun Cable will connect a 17-20GW capacity solar plant to Darwin with an 800km High Voltage Direct Current (HVDC) transmission line, which then connects to Singapore via a 4,500km HVDC transmission subsea cable (Australia-Asia-powerlink). Expected to be operational by 2027, the $35 billion project has...
The Step Change scenario in the 2022 Integrated System Plan (ISP) is targeting 83% renewable energy generation in the NEM by 2030-31.

When project developers evaluate the potential profits for a new battery project in the NEM, one key variable being considered is the maximum allowable cycling rate of the battery. Cycling at higher rates can enable more arbitrage profits to be earned, but every MWh of energy that passes through the...
How does thermal storage stack up compared to batteries?
Along with the retirement of coal/gas power plants in the NEM, long-duration energy storage systems (LDESS), often exceeding 8 hours of storage, are becoming more crucial in transitioning to a more sustainable and renewable energy future. LDESS technologies, such as battery storage systems (BESS), thermal energy storage systems (TESS), compressed...
VNI West selected path; an incentive for delaying coal retirements?
On 29 May 2023, AEMO published a conclusions report on the VNI West Project. According to the report, option 5A (a variant of AEMO’s preferred option in a previous consultation paper) is preferred for VNI West. In option 5A, the transmission line crosses the Murray River north of Kerang (Wamba...
NSW’s transition to a new era: What will replace Eraring?
After 52 years of operation, the NSW Liddell power station officially shut down last 28 April. With Liddell’s closure, NSW’s transition to a green energy future is in full swing. First announced in 2015, NSW had seven years to ensure there is enough replacement capacity once Liddell is retired. Since...
Recently in the news, there has been some concern that the closure of the Liddell power station in NSW will be a repeat of what we witnessed in 2017 with the closure of Hazelwood. Hazelwood’s closure led to higher prices, particularly over summer peak demand periods1. This is a poor...
Exploring the impact of storage assets on QEJP sensitivities
Battery storage has great potential to generate high revenues during large market shifts, especially in Queensland (as shown in our previous analysis in Cotw #158). The Queensland government’s recently announced Energy and Jobs Plan (QEJP) would be another big shift as it aims to reduce the state’s reliance on generation...
Patriots ‘Dynasty’ off to a rough start, as New England suffers loss to the MLFs…
For many, the first of April is marked in calendars as a day for jokes and silly nuisances. For the few, specifically the energy industry, we have it pencilled in for the release of the upcoming year’s Marginal Loss Factors (MLFs). Over the last half-decade, movements in MLFs have received...
For the first time in the history of the Western Australian Wholesale Electricity Market (WEM), the balancing price reached the maximum price limit of $1,018/MWh between 5:30pm and 7:30pm on Tuesday, 29 November 2022. This came one month after the state-owned Muja C Unit 5 coal power station was closed....
Crying over spilled solar – how much can a battery help?
A standalone battery earns its revenue not only from the arbitrage opportunity between day and night prices but also from participation in FCAS markets. This remains true when the battery is paired with a solar farm but can be complicated by constraints or trade-offs between FCAS participation and solar export....
Australia’s hydrogen success is tied to energy market policies
