Battery of the nation + hydrogen export: Can they do both?

The Tasmanian government have announced that they will set a target to double their current renewable generation by 2040. Based on current market dynamics, this means that Tasmania will likely need consistent renewable generation of around 2.4 GW (assuming average requirements) or 3.4 GW (if scaled to peak demand). This opportunity to double renewable generation […]

Out of sight, not out of mind: DER record growth continues

The growth in behind-the-meter distributed energy resources (BTM DER) has been a key feature of the NEM over recent years. BTM solar has grown from ~1-2% of total energy supplied five years ago to ~6% this year. In fact, looking within the day, the percentage of supply being provided by rooftop solar has been as […]

SA shatters record: lets talk about the elephant in the room…

As springtime rolls around in the NEM, those with interest in the market are always keeping an eye on South Australia to see just how low operational demand will go and when (not so much if) the record will be broken. This year has not disappointed. On 11 October 2020 at 12:30, South Australia recorded […]

Need a little controversy; ‘cause it feels so empty without me?

Last week, in our chart of the week we wrote about the Federal Government’s announcement surrounding the replacement of Liddell with 1,000 MW of 24/7 dispatchable gas capacity. A week can be a long time as this figure has now fallen to 250MW – much more in line with AEMO’s suggestion in the ESOO that […]

GPG: From middle of the order to the nightwatchman?

Across multiple reports published in recent weeks, the topic of changing supply dynamics has been a key focus as more renewable energy resources continue to enter the system including both grid-scale and behind-the-meter assets. Much of the commentary has focussed on the changing operation of coal generation in the face of increased solar penetration, however, […]

Ramping: Brought into focus but always in the frame

With the release of AEMO’s Integrated System Plan (ISP) comes increased commentary on the need for power system services critical to ensuring the secure operation of the NEM. Of growing importance are services to provide voltage control and system strength, frequency control and inertia, ramping and dispatchability. In this week’s ‘Chart of the week’, we […]

Race to the bottom: Negative prices on the rise and spreading

Negative prices are becoming a more frequent occurrence in the NEM as variable renewable energy (VRE) plays a larger role in the supply mix. Negative priced offers from generators form a large part of the MW capacity offered into the market. The negative prices we see in dispatch intervals reflects the situation were there is […]

Down, down, prices are down… but is it sustainable?

Following a comparatively mild Q1, electricity prices have fallen significantly in Q2. While a drop in price is expected as we move from peak demand conditions in Q1 to the shoulder Q2, the surprising element is the level to which prices have fallen. Average quarterly prices in Q2 2020 were between $33-43/MWh – a significant […]

VNI West RIT-T: another route-to-market for battery storage?

Over the last week, we have been reading through stakeholder submissions to the Victoria to New South Wales Interconnector West (VNI West) Regulatory Investment Test for Transmission (RIT-T) Project Specification Consultation Report (PSCR). For the most part, the submissions were in support of options 7 and 6 (Figure 1). However, there was one submission that […]
