Solar Export Tariffs in GB

  Introduction Our previous post compared the value that residential PV solar owners in Australia can get from the various Feed in Tariff (FiT) schemes in different states. We found that the relative economics of wholesale market prices and FiT schemes varied...

Solar Feed in Tariffs in Australia: Who’s Getting a Raw Deal?

  Introduction In recent years solar feed-in-tariffs (FiTs) in Australia have been falling steadily to reflect both changes to the underlying wholesale markets, but also in acknowledgement by governments that solar no longer needs juicy FiT incentives to fly....

Modelling community batteries

Here's a quick video building on our recent blog post on community battery network tariffs. I've taken one of the trial tariffs and added in the perspective of how the battery might reduce network cost at the local distribution level.

Is London a better investment for solar than Sydney?

Following my trip to the UK earlier this month I was struck by a couple of things related to solar PV investment. One was the weather; London turned on the sunshine big time. The other was the current trend in the UK energy market to dumb down price signals to energy...

DER Orchestration in the WEM

Western Australia is a global hotspot for high-penetration of distributed generation in the electricity system, and the Government proactively defined a roadmap for DER integration and orchestration in early 2020. In line with the roadmap, Government has recently...

What does seasonal variation mean for the NEM?

Is the NEM a winter or a summer peaking market? Australian summers are hot, so summer, right? Right? Well, it’s not quite so simple. Let’s look at each of the five regions in the NEM, explored in the glorious Neapolitan palette of the Grand Budapest Hotel. 1. These...

Five kinds of solar curtailment

Western Australia has recently joined South Australia in implementing a 'Distributed Generation Management' scheme, whereby some roof-top solar systems can be remotely turned off by the electricity system operator. Not surprisingly, that has raised eyebrows in the...

Modelling Dynamic Operating Envelopes with Gridcognition

Distribution limits Australia is leading the world on the deployment of distributed generation and South Australia is the poster child for this; we had events last year where almost all of SA's electrical load was met by roof-top solar. But there is a limit to how...

When turning off your solar system can make you money

Nudged along by Anthony Seipolt's post on AGL Australia offering a new retail tariff incentivising residential customers to turn off their solar systems in return for some cash (importantly, more cash than they'd otherwise get from their feed in tariff), here's a very...

A world first? Probably.

A world first? Probably.

Only a few years ago debate was running hot over whether even relatively low levels of renewable energy in the world's electricity grids was achievable, and back then "renewables" typically meant large utility-scale assets. Back then few people would have seen this...

EV Charging: Friend or Foe?

  Electric Vehicles are going to be a very big deal for energy systems right around the world. Even at their simplest they are pretty serious energy assets, with a relatively small EV like a Nissan Leaf still having a battery several times larger than a typical...

FCAS: The value stream everyone’s talking about

In recent times contingency FCAS has become a very lucrative revenue stream for participants in the NEM able to offer services into the various contingency markets. In particular, owners of battery storage systems have trousered some serious coin, often exceeding...

Western Australia lets the tires down on rooftop solar

Western Australia lets the tires down on rooftop solar

  Yesterday, WA’s government announced a change to the regulated feed-in-tariff that’s offered to residential owners of solar PV. From November 2020, rather than receiving a flat 7c/kWh for excess solar exported to the grid, the new scheme will incorporate a...

Solar PV isn’t just about yield

Inspired by the lively discussion that resulted from Gavin Mooney's recent post on what direction to point roof-top solar systems, we crunched a few numbers to help inform the conversation. The analysis looks at a single commercial load shape (I picked an office...
