Am interested to know which countries are the most advanced in DR? I thought the US was well up there, but if they are also curtailing wind farms, what's going on?

I wonder what the system marginal price (SMP) was during the curtailment. Of course it was very low. If demand response (DR) was in use in Ireland at that time then a market would have been created as the price plummeted. Those 'cheap' uses for electricity such as heating municipal swimming pools are typically fossil fuel replacement applications. If you have found the right curtailment period in the charts they approx 600 MW hours of energy was lost. A quick calculation says that about 100 tons of carbon dioxide could have been displaced by using that energy. And the wind farms that were curtailed lost €40,000 in revenue for this one event. We are at 9% renewables right now. Imaging how much curtailment there will be when we get to 33%. Just a thought. I wonder what the system marginal price (SMP) was during the curtailment.

We must therefor introduce some flexibility into our demand. All that is necessary to do this is to enable the wholesale system marginal price market translate into the retail market. This is a very tractable IT problem. However traditional TSOs do not understand the problem let alone the solution.
