CleanCo – little ripples make big waves

Many would have noticed that CleanCo received their electricity retailer authorisation from the AER recently, signifying a key step to providing retail electricity services to customers. For those not familiar, under the National Electricity Retail Law, a retailer authorisation is needed prior to engaging in the retail sale of energy. Now, Cleanco can sell electricity […]

Distribution networks unDER the pump

Rooftop solar has grown rapidly over the last decade with numbers indicating that almost 10 GW has been installed across the NEM and AEMO’s projections indicate that there is still plenty more to come (~4 GW over the next decade). Effects of behind-the-meter (BTM) solar on market outcomes are well documented (including by us); so […]

You’re gonna need a bigger boat: NW VIC in the waves of change

The situation in north-west Victoria has been at the center of many discussions over the last fortnight, particularly in light of the West Murray Technical Forum held by AEMO. Back in September 2019, issues with system strength saw five solar farms have their output curtailed by up to 50%. At the time, voltage fluctuations were […]

It’s gettin’ hot in here: SA VoLL – a prelude to summer?

Summer is well and truly here with mercury readings this week showing warm temperatures across the NEM. South Australia in particular has seen maximum temperatures hovering around 40°C for the week. In this Chart of the Week, we take a look at NEM outcomes this week where moderately high demand, forecast Lack of Reserve (LOR) […]

Prices in the NEM: Is variability the new black?

The price escalation in the NEM in recent years has been well documented. Closure of ‘low-cost’ coal generation (particularly Hazelwood) has seen average prices in the NEM increase significantly as the overall supply/ demand balance tightens. Some of this tightness has been alleviated by the significant development of variable renewable energy, however, with this comes […]

The more things change, the more they stay the same…

In this week’s chart of the week we focus in on the comparatively small but important Frequency Control Ancillary Services (FCAS) markets in the NEM. FCAS in terms of total dollars is miniscule in comparison to the total energy bill. While the proportion may appear small, its function is key to maintaining a secure operating […]

Price-taker to price-setter: The emerging story of wind in SA?

It is old news that the NEM is undergoing transformational changes in its generation mix. These changes to the fuel mix are having significant commercial impacts in price outcomes observed in the market. In the last few months, we have seen an unprecedented number of negative price intervals across the National Electricity Market (NEM). Of […]

Marginal loss factors: are we going average or what?

Marginal loss factors (MLFs) have emerged as a hot‑button topic in the National Electricity Market (NEM) after being a relatively unexciting feature of the market. Previously, in the period 2000-2015, MLFs were reasonably predictable and variations year-on-year were minor. This reflected the stability of the generation sector with much of the supply provided by large […]
