At this moment, Spain has about 150 MW of thermo electric plants
connected to the grid; some 750 MW are under construction and some 14 GW
of these types of plants have requested license and have established the
required bonds by the Spanish government. There are basically three
types of plants:

Senior Electrical Engineer questions political risk of Czisch type supergrid
Bernard is a senior electrical engineer and has sat on many generation industry committees. He writes:
“I unfortunately missed the House of Commons presentation. I think we all agree the we could overcome technical problems at a price. However how do we overcome the political risk ? In the coal, nuclear, oil and gas areas this is dealt with by storage and multi sourcing. I don’t know how we factor in the cost of occupying a country while alternative supplies are built – even if it were possible. Any comments”

Regarding political risk.
All turbines can be in EU not in dodgy foreign countries.
First of all, lets be clear, the Czisch concept / proposition is not built solely on the assumption that supplies coming from Egypt, Kazakhstan and so on as many people in this group seem to wrongly assume. The key point is that a supergrid be built linking up the EU states including Iceland and Norway. This has enormous technical and economic benefits for all power generation (but not the companies owning them – it introduces a free market which I am in full support of, but they are not), and will make the whole thing more efficient, by allowing plants to run smoothly, and lead to the obsolescing of numerous inefficient existing stations which will no longer be needed and a massive reduction in expensive spinning reserve and hot standby (- this is the key reason why there is no support form the big players – it will strand many of their assets and make it unnecessary to build a lot of the new coal plant they want to, irrespective of any renewables. Just as building the UK supergrid in 1930 made a lot of UK power stations redundant, and forced a lot of those local monopolies out of business.) However putting a lot of wind farms in far flung places is the cheapest way of getting power – but that is only one option!. If we don’t do it, and put all the turbines within EU proper, it costs a bit more, but not a lot. (Mark Barrett has already shown this

National Grid's views on 36% wind in UK power generation mix
Dear all, Regarding the concerns expressed in this dialogue (on the claverton mailing list – ed) regarding the intermittency of wind and the risk to the transmission network of having a large percentage of wind generation on the network. The National Grid has in the last year established what it calls its “Gone […]
From Electrical Review – Arc Flash danger
Blown Fuse – Why are we happy to work in the minefield?
WEB EXCLUSIVE Before embarking on this month’s rant, let me state I am not in favour of the nanny state. I object to traffic calming measures, other than around schools and hospitals; I find it facile that ofcom demands that TV shows can only depict car thieves if they’re shown driving off wearing their seatbelts; and I don’t think playground conkers is a blood sport!
However, while to the best of my knowledge there have been few, if any, conker related fatalities I have been drawn to a statistic that is frankly alarming. About ten people a day in the UK suffer severe injuries, or worse, as a result of electrical crossovers – I still prefer the term arc flash. This figure is appalling, but may not even be accurate since that estimate is drawn only from victims reporting to major burns units. How many more minor injuries and near misses go unreported is anybody’s guess.
Talk by Dr Gregor Czisch at the 5th Claverton Energy Conference, House of Commons June 19th 2009
Dr. Czisch gave a very interesting presentation the contents of which is summarised here, Rather than publish a paper on this set, Gregor has given us these links to his site where the varous papers can be studied.
The most relevant one for English speakers is probably this one:
“Low Cost but Totally Renewable Electricity Supply”
Active Power Article – Flywheel energy storage
Summary – this article offers compelling reasons for using a flywheel in combination with a diesel generator for UPS. Essentially batteries are the weakest point of any generator, and the flywheel eliminates the need for them, by storing enough energy to start the generator, and to provide no break power whilst the generator is starting. This article is written by and features Active Power who manufacture these systems.
As compared to other energy storage technologies (i.e., flow battery, compressed air, hydrogen, lithium ion battery, etc.), flywheel technology is a very mature, field proven technology. It’s worth noting Active Power was the first to commercialize a mechanical flywheel energy storage system and soon after patented the integration of UPS electronics with flywheel energy storage. Flywheel operation is very well understood and Active Power alone has more than 2,100 flywheels deployed in the field to date with more than 55 million hours of runtime. Flywheels present the most power dense energy storage technology when used as a bridging device between an outage and on to a generator.
Why Do We Need The Supergrid, What Is Its Scope And What Will It Achieve?
Claverton House of Commons Presentation, 19th June 2009 Note – The Claverton Energy Groupcomprises about 300 independent energy experts who discuss energy issues. Not all members support the Supergrid concept, however a significant proportion, if not most, do. Dr Czisch presented at a recent Claverton Conference held at the Headquarters of Wessex Water in Bath […]
