The future of Britain's electricity networks - Energy and Climate Change Contents


Memorandum submitted by the British Wind Energy Association (BWEA)

  BWEA, the trade association for the UK's wind, wave and tidal stream industries, welcomes this opportunity to comment on the future of the UK's electricity networks. BWEA's 460 members will be in the forefront of delivering the renewable power necessary if the UK is to meet its commitments under the new Renewable Energy Directive, and also the carbon dioxide emission targets as set out in the recent Carbon Budget.

  The electricity system of the 21st century will be considerably different from that of the 20th century. Previously, system controllers dispatched generators to meet demands that were regarded as generally uncontrollable. In the future, we will have a mix of dispatchable and undispatchable plant, which must be managed to meet demands which will be partially controllable. This new management paradigm must be supported by a grid infrastructure which is extended to areas of high renewable resource that the current network does not reach. These will be the challenges for network owners and managers in the coming decades.

A vision for the networks

  The vision for the long-term future of the UK's power networks depends on the vision for the long-term generation mix. The outlook for 2020 is becoming clearer, but given the long lifetimes of transmission assets, there will need to be clarity about the vision to 2030 and beyond. This is to allow for the necessary strategic planning of the grid itself, and so that the various supply chains for the generation plant and the grid equipment can invest with reasonable certainty of return. The investments required for manufacture and installation of offshore wind turbines will be easier to justify for a market that extends for 20 years; similarly for cable manufacture. If the UK gets this vision and its implementation right, then we can capture a significant portion of the value for UK plc, including opportunities to export products and services to Europe and the rest of the world, as the globe moves to a low-carbon economy.

  BWEA strongly welcomes the publication of the Electricity Networks Strategy Group's report Our Electricity Transmission Network: A Vision For 2020, and Ofgem's consequent approval for investment in the pre-planning work required to deliver on the vision. We remain concerned, however, about the mechanisms to deliver this infrastructure. Whilst BWEA is engaging with and welcomes the Ofgem process to set a new incentive framework that allows Transmission Owners to invest ahead of user commitment, in return for a higher return, there does not appear to be an actor with which the "buck stops", and who will ensure that delivery happens. Until there is clear leadership here, BWEA will continue to be concerned about delivery of the vision.

The regulatory framework

  The Transmission Access Review (TAR) and the consequent work to implement its conclusions are very welcome from BWEA's point of view. The new framework allowing investment ahead of user commitment is vital here. We are still, however, some way from the implementation of the TAR principle that projects should be able to obtain a firm connection date within a time frame reasonably consistent with their development timescale. Along with our colleagues across the renewable energy industry, BWEA has long been a strong supporter of the "Connect and Manage" concept of transmission access. We understand Ofgem's concerns about the rise in constraint costs that will result from such a system, but believe that the regulator's fears about these costs are exaggerated. This was most clearly brought out in the impact assessment of CUSC Amendment Proposal 148 (CAP148), where alternative analysis commissioned by BWEA showed net costs of £23m, compared to the Ofgem analysis of £917m.

  In this context, BWEA is deeply concerned about the recent activity by Ofgem in instigating urgent modifications to the CUSC due to concerns about constraint costs. This sudden raising of the stakes around an issue which has been on the table for some time is causing some consternation, as well as straining the resources of our sector to respond to a cascade of consultations in a short period on issues of fundamental importance.

Technical, commercial and regulatory barriers

  We have discussed some of the regulatory barriers above. Also of key importance is the consenting process for the new infrastructure required. Repetition of the experience with the Beauly-Denny line in Scotland will ensure that targets are missed. The passage of the Planning Act is welcome in this regard, and we look forward to the Infrastructure Planning Commission making a difference here. The National Planning Statement that will govern the IPC's decisions in this area will be important here.

  Regulation and charging for the grid need to reflect the different characteristics of renewable generation, and the consequent differences in their use of the network. The Security and Quality of Supply Standards (SQSS) are designed around dispatchable thermal plant, and need to be reformed: BWEA is engaging with the Review of SQSS that is currently under way.

  In order to deliver the network capacity required, strong and consistent signals need to be sent to the supply chain. One key example is offshore, where approximately 7,500km of HVDC cable will be required by 2020 to link up all the offshore wind projects planned: current global production capacity of this cable is around 1,000km/yr. Combined with other offshore wind programmes such as Germany's, there will need to be a massive scaling up of production. If the right signals are sent to the cable companies, the resulting factories could be sited in the UK, with benefits in terms of jobs and possible exports.

  Skills will be important to delivery of the new network capacity: BWEA is working with EU Skills on plans for a National Skills Academy for Power, which should help in this regard.

The offshore transmission regime

  BWEA supports the regime as currently being drafted for transitional projects; subject to the modification and further clarity in the current consultation. The system should be appropriate for the "radial" connections to shore that the Round 1 and Round 2 offshore wind projects need.

  However, industry is unified on the need for a more strategic approach to the offshore transmission network. The business environment surrounding the proposed regime has changed with the current financial crisis, increased competition in the global supply chain and the interpretation of EU requirements effectively preventing generators from owning their own transmission assets. These factors have increased the uncertainty around the ability of planned regime to deliver transmission infrastructure on a scale and timing needed to meet 2020 targets.

  Therefore, we recommend that DECC and Ofgem establishes, at the earliest opportunity, a route map setting out how the competitive tendering process will apply to non-transitional and Round 3 projects in order to deliver the required investment to meet the UK targets.

  Industry believes that for each of the nine proposed Round 3 zones there should be one OFTO appointed. This would mean that one competitively appointed company would be responsible for connecting a number of projects in the same geographical area. This would allow a more coordinated approach so that investment can be made in early stages that will facilitate the efficient connection of later stages. In addition, this approach should ensure compatibility with future European interconnection.

"Supergrid"

  Installation of much larger interconnection capacity with mainland Europe and its "meshing" to form a "supergrid" will bring key benefits. Most important will be the ability to absorb much larger amounts of variable renewable generation in the wider network that will be created. This is especially the case if the large hydro capacity of Norway is used as a storage buffer. There is a key need to sort out the regulatory issues involved in this expansion of interconnection, and UK Government should actively engage in this process. At present there is a sense that DECC is taking an attitude that this is a European project that is happening "out there" in Brussels and elsewhere. If there is to be timely progress on this project, the UK must be an active partner. Without clarity on the regulatory issues, then the cables cannot be laid, so this is the necessary first step.

Embedded and distributed generation

  The large amounts of generation that will connect to the distribution network throw up challenges to the management of these grids. There must be more active management of generation and demand in the lower voltage grids, perhaps with "Distribution System Operators" (DSO5) on the TSO model. This issue is being addressed in the RPI-X@20 Review that Ofgem is conducting. However, this is explicitly excluding any impact on the current Distribution Price Control Review; measures to enhance the distribution networks' ability to manage distributed generation will need to be implemented in the 2010-15 period that the DPCR covers.

Cost of upgrading networks

  The ENSG report referred to above gives a figure of £4.7bn to provide the necessary onshore grid. It should be borne in mind that the choice is not between spending £4.7bn or nothing; there is a need to invest in a network coming to the end of its design life. The choice is between this investment to create a grid fit for the 21st century or investment to recreate the 20th century grid. This money will come from private investment, recouped through Transmission Network Use of System (TNU0S) charges. Government funding will not be required, though actions to bolster the finance sector for these investments would be welcome (see below).

  The amounts required sound large, but are only a small proportion of customers' bills. The expenditure is required to allow us to meet carbon and security of supply objectives. It is also required to allow maximum deployment of renewables and thus gain the most value for money from the Renewables Obligation.

Funding investment

  The low-risk, low-return assets that regulated transmission investments give should be very appealing in the current economic climate; institutional investors and private capital generally is interested in this sector. There may be a role for the European Investment Bank or similar institutions: there have been proposals for a state "green" investment bank, funded by "green bonds", with infrastructure such as networks a key target. BWEA would welcome such moves.

Innovation

  Most innovation in this area needs to happen in the distribution sector—the "smart grids" which many have discussed. The poor take-up of the Innovation Funding Incentive (IFI) and Registered Power Zone (RPZ) programmes is therefore disappointing. We would welcome action to encourage the DNOs to take up and expand the funding available to such projects.

  At the transmission level, there needs to be more flexibility in grid codes to allow innovation. This should come via the SQSS review referred to above. The Code Governance Review that Ofgem is leading also needs to look at this issue.

  More investment in innovation is necessary if we are to maximise the amount of renewables on our grids. The culture of "sweating assets" and cutting down on unnecessary expenditure that has prevailed since privatisation has resulted in low spending on innovation generally. This needs to change. However, there is a confusing plethora of funding bodies in this area, with remits that either overlap or leave gaps. Government needs to rationalise this area and direct more funds to energy innovation generally.
