Talking New Energy · 248. Are wind PPAs about to become more expensive? · 14 Jul 2026 podcast

Thank you.

Thanks, Sam.

Yeah.

Hi everyone.

So suddenly, yes, my Lord Energy friends have told me that I use some unexpected words when I talk about work, and cannibalization is one of those.

So cannibalization in this context happens when we add more intermittent renewable generation to the system.

So for those not in power, traditionally we've had merit order curve, or most of us would know as a supply curve.

curve made up of all different types of fueled generation.

So your gas stations, your coal stations, and you end up with a supply curve made up of different efficiencies, different fuel types, and it's a nice smooth supply curve going up to very high levels.

Intermittent renewable generation, so bin generation for example, does not really have much in terms of short run marginal costs.

So it essentially pushes the merit order curve, the supply curve out, and the market clearing price is therefore going to be lower and lower as we add more and more intermittent renewable generation onto the system.

So what that means is that intermittent renewable generator might look at the prices today and think that's the price that I'm going to achieve.

But actually, just by having more intermittent renewable generation on the system, like wind,

That is in and of itself going to be reducing the market clearing price both for itself and for everybody else.

That's right.

Yeah, that's a great point.

Ultimately, just because this short run cost is very low doesn't mean that these power stations don't cost anything and they do actually have to make money.

So if what we're seeing is that they can't reach that money in this space, that is going to have an impact on the commercial side.

So for a developer, for example, that's looking to build a new power station, they have to be aware that just by building their

new power station, they are going to be reducing the price that they themselves can achieve in a very kind of extreme situation.
