Keeping The Lights On

It’s not very often that Energy Matters gets a mention in the “mainstream media” but last week Roger and I got a mention in UK satirical magazine Private Eye (no 1437). In his column, “Keeping the Lights On”, Old Sparky had commentary on the Swansea Bay tidal lagoon and says this:

“But painstaking tidal analysis by respected energy industry analysts Euan Mearns and Roger Andrews shows there is no practical combination of lagoons that could even out the bursts of electricity from this airily conjured “fleet”.”

Green Mythology: Tidal Base-load Power in the UK

Scientists working at The University of Liverpool and the NERC Proudman Oceanic Laboratory have developed elegant computer simulations of electricity generation from tidal barrage and tidal flow power stations deployed in the Severn Estuary and the East Irish Sea. The models show that no combination of tidal system from this area can produce continuous and uniform base-load generation. Despite this, these workers conclude that it can. Adding pumped storage hydro provides an economical and practical way to smooth out daily fluctuations but cuts peak output by over 50%. Large-scale deployment of tidal stations will modify coastlines that deploying renewable energy is supposed to prevent. Continue reading

Swansea Bay Tidal Lagoon and Baseload Tidal Generation in the UK

Charles Hendry, former energy secretary, published his long awaited report on the Swansea Bay tidal lagoon power station last week coming down in favour of the project. Hendry’s report is comprehensive but has one key omission. It does not ask if tidal lagoons can provide renewable base-load power in the UK as is often claimed. I set out in a positive frame of mind to show that it could, but failed miserably in that attempt. Facts defeated me.

UK tidal lagoons will produce more intermittent electricity than any other form of renewable generation providing four spikes separated by four periods of zero production each day. It is often claimed that the predictability of tides is a virtue. This also means we can predict with certainty that this energy source will be a disaster for the public as well as the environment.
