Lord Offord of Garvel (Con)

My Lords, as we have heard throughout the debate on this Bill, as well as in the other debates in this House on the future of our energy, we know that renewable energy by its nature will always be unreliable. It is, by its nature, intermittent. Many of us have expressed concern that this undeniable fact will result in shortages. As has been mentioned by my noble friend Lord Murray, last year Europe in fact experienced several episodes of Dunkelflaute. On the other hand, as has been highlighted by my noble friend Lord Ashcombe, what happens to energy supply in periods of persistent sunshine and wind? Unfortunately, we find ourselves in a position in which the national grid is unable to cope with excess renewable energy supply. Grid capacity is a particular challenge for the offshore wind sector, because those sites are necessarily located far from sources of demand. Currently, the national grid pays renewable energy generators billions to reduce supply when there is more renewable electricity than the grid can manage. This problem will only be compounded by the Government’s ambition to build renewables faster than we can develop and connect them to the grid. With that in mind, we should address the fact that the timeframe for obtaining grid connections for a new energy project can reach 10 years. Not only this, but a project without a grid connection today may not come online until well after the Government’s target of grid decarbonisation by 2030. There is no doubt that the renewable energy projects that will supposedly be supported by the establishment of Great British Energy will face the same connectivity difficulties. As my noble friend Lord Ashcombe highlighted, over £1 billion was coughed up by bill payers last year to pay renewable energy generators to curtail excess supply, including £20 million in one day alone. This will only worsen under the Government’s agenda, and it will be consumers who will bear the cost via their energy bills. If renewable generation is scaled up so rapidly without the grid capacity to transmit it to the areas of high demand, those curtailment payments will only increase. We know that excessive curtailment fees are already being paid to wind farm operators who are generating more power than can be used. This is paid to get operators to switch off their wind farms and avoid overloading the grid. How ridiculous is that? We expect these curtailment costs only to rise under the new Government’s regime, and by 2030 it is possible that there will be a staggering £20 billion a year in subsidies and in maintaining back-up grid capacity. That equates to roughly £700 per household each year. I turn to the amendments in this group in the name of my noble friend Lord Murray of Blidworth, which I support in their entirety. Amendment 85E requires Great British Energy to “report annually on the impact of each investment it makes on the levels of curtailed renewable energy in the UK”. Amendment 85D requires Great British Energy to “invest in additional energy storage infrastructure to store excess renewable energy”, and thereby minimise the cost of curtailing excess supply. In tabling these amendments, my noble friend has addressed many of the issues that I have discussed. It is essential that the establishment of Great British Energy does not cost the taxpayer more than the already allocated £8.3 billion, and that it assesses the impact of its investments on the cost of wasting excess supply and prioritises the means of storing renewable energy. I hope that the Minister will agree.
