My Lords, I wish to speak to Amendment 1. The noble Lord, Lord Howell, disposed of the previous version of this amendment most effectively in an eloquent speech in Committee, yet the Liberal Democrats persist in asking for an unequivocal value-for-money assessment of any project to build a new nuclear power station. It is not clear on what basis such an assessment should be made.
They may be inspired by the expectation that an assessment conducted according to commercial accountancy would cast doubt on the economic benefits of building new nuclear power stations. It has been pointed out to them that such a valuation would entail the commercial cost of capital funds, which are available from the financial sector only at an exorbitant rate of interest. It is precisely for the purpose of overcoming this impediment that the financial device of a regulated asset base, which is what this Bill advocates, has been devised.
Commercial accountancy—if that is what the Liberal Democrats have in mind—would be a most inappropriate means of assessing the value of investment in social and economic infrastructure that would provide us with a carbon-free source of electricity for the long term. Not only will this electricity be making a vital contribution to our climate change agenda but it will
serve to sustain our industries in the absence of fossil fuels. Surely the Liberal Democrats should support such objectives.
The Liberal Democrats have been enjoined to tell us how they envisage that we might satisfy these objectives in the absence of the secure and reliable supply of electricity that would be provided by nuclear power stations. They have failed to do so. They have failed to tell us how the problems of the insecurity and intermittence of the supply of electricity could be addressed if it were dependent on the wind, the sun and imports from abroad. We must assume, in the absence of any declaration from them, that this is what they envisage. The truth is that they have failed to address the logistics of the energy supply in a meaningful way.
The value of renewable sources of power must be assessed not only on the costs of what they are able to produce but on the costs of what they fail to produce. At times when this power is not available, other sources must be found. In the absence of a baseload of electricity, they are liable to become exorbitantly expensive when there is a dearth in power. Wind and solar power will not satisfy the demand for a greatly increased supply of electricity, which must arise if our industries and our transport are to relinquish fossil fuels. The renewable sources of power would serve to satisfy the demands only of a wholly deindustrialised and socially immiserated version of the United Kingdom.
