Swansea Bay Tidal Lagoon.

Have not done much on this blog on energy generation for a while. Over next few weeks hope to keep my eye in on this developing policy area. It's been an interest for a year or two. Just read through some correspondence eulogising about the benefits arising from a Swansea Bay Tidal Lagoon as clearing my desk. It's only because I have absolutely no idea of Govt thinking on this project that enables me to comment at all. It's a project I've had an interest in for a couple of years and it would be accurate to describe me as an enthusiast for the project.

It's main attraction is that it could be the forerunner to several other tidal lagoons. What we have been told by the developers is that if the Swansea Bay Tidal Lagoon were to go ahead, it would be followed by others, bigger and less expensive. Tidal power has the potential to deliver flexible, predictable and clean electricity. And quite a lot of it. Former energy minister, Charles Hendry is soon to deliver a report on the potential of tidal power. And some in the sector are pointing to next week's Autumn Statement as being significant. Not so sure myself. But I do think we are moving towards an assessment of tidal power's potential.

You might think from the above that I believe the Govt should give the go-ahead to the Swansea Bay Tidal Barrage. You would be mistaken. cannot do that until I study, and take a positive view of the costings, business case and opportunity costs of the project. I feel certain there must be a cost effective way of harnessing tidal power. But we just don't yet know whether the financial case for a Tidal Lagoon in Swansea Bay is it. We can but hope it might be.

"clean electricity" - no such creature ... There has never been clean electricity and never will be. Energy transformations ALWAYS have some kind of impact on the environment. Tidal Lagoons are no different. The impact on ecology along the shoreline is REAL. Look at Cardiff Bay - the ecology of the mudflats was SEVERELY impacted. Not saying we should not obtain electricity from exploiting the potential energy that arises from tidal inflows, but please stop pretending it is 'clean electricity', because it is OBVIOUSLY not.
