Back on 8th October, I spoke at All Energy in Melbourne on this topic. Given the questions posed after the session, it seemed that it might be of value to some WattClarity readers if I narrated over the top of the presentation and included it here, for future reference.
A quick look at how ramp rates would vary (for “Unserved Consumption”) in the hypothetical “10x” high intermittency grid.
Continuing our analysis of these hypothetical future scenarios to understand the shape of “unserved energy” and hence the potential contribution of Demand Response – today I post about energy spilled in a future with high intermittent generation supply.
A sped-up animation covering spanning a September 2015 weekend in the South Australian region of the NEM, illustrating both sides of the wind farm output coin.
Some further analysis of different aspects of wind farm output in South Australia
Pondering more implications of the boom/bust pricing witnessed in the South Australian region last week…
Through the week we’ve seen new highs for wind production (NEM-wide) and also some low levels of production, as well – mirroring the political debate. The challenge has serious implications, however, and the AEMO sessions mentioned might be one way to learn more.
Windy conditions persist – and bring with them their own challenges for the AEMO in managing the security of the system
(PS wind contributes to, but there are other factors discussed in the post)
Looks like wind output, aggregated across the NEM, hit a new record in output overnight.
Continuing the theme of investigating peak metrics over summer 2014-15, today we look at peak wind output (aggregate across the NEM).
Some back-of-the-envelope calculations being a starting point to help me understand how much real contribution electric vehicles might make in feeding back into the grid when intermittent generation is absent.
Some initial analysis of the interplay between wind and solar in Australia’s National Electricity Market
What’s summer shown us so far, in terms of where peak wind output has landed (and why are we surprised).
A quick look at how aggregate wind farm output has trended, over the history of the NEM
Our popular competition returns, with some added spice as a thank-you to clients who have supported us in our 15 years of operation.
There are cycles in wind production in the NEM, and there are cycles in social media about the benefits and disbenefits of renewables.
Low prices today in South Australia and Queensland for various reasons – but summed up by a large oversupply of capacity
In parallel with the RET Review process, claims and counter claims are mounting about challenges to security of supply, moving forwards. Here are some initial thoughts…
Some analysis of carbon emissions for large generation portfolios in the NEM, and comparison with prior post about wind production levels.
Coincident with the release of the RET Review, activity in the spot market provides some reminders…
