Written evidence submitted by Solar Energy UK (REW0037)


Solar Energy UK welcomes the opportunity to respond to this call for evidence. The coronavirus pandemic has affected all Welsh citizens, businesses, and local authorities, including the many workers and SMEs in the solar industry. Priority must be given to addressing immediate health impacts, but it is also imperative to take strong political action to ensure the Welsh economy recovers sustainably. Calls from across society for investments in innovation, green technologies, and a clean energy transition must be swiftly translated into meaningful action to power the Welsh economic recovery. 

What opportunities are there for renewable energy to aid Wales post-COVID 19 economic recovery?

A Solar Powered Economy

The Committee on Climate Change estimates the UK as a whole will need 54GW of solar PV by 2035, to achieve the Government’s net zero targets, representing a deployment rate of roughly 3.7GW per annum through to 2050.[1] Wales has the potential to contribute more significantly to the UK effort to achieve this target. Our market intelligence estimates that Wales has 1.2GW in the planning pipeline, of this 250MW has already secured planning permission.2

The industry is continuing to innovate, deploying the latest technologies, and exploring new opportunities accelerate grid upgrades. Creating additional grid capacity is crucial to Wales’ journey to zero carbon generation. The Welsh grid is under a significant amount of strain, it is understood that there are parts of the country where the grid is close to full capacity, this is especially true of mid Wales.

Solar is a powerful job creator and an inherently rapid technology to deploy, as well as one of the cheapest forms of power generation today, with costs of solar PV having fallen by over 80% in the last decade.[2] As such, it can play a central role in driving the Welsh economic recovery and energy transition. However, both national and devolved governments must work with industry to remove economic and regulatory barriers and unlock the solar and storage industry’s potential. 

Rooftop solar, particularly the residential sector, benefits from very short project lead times alongside minimal design and permitting requirements. Current projections show that due to the high labour intensity of solar as many as 1.5 million jobs could be created across the solar value chain throughout Europe by 2030. Workers can easily be up skilled to deliver the installation, operation, and maintenance of solar projects. Furthermore, the strong health and safety protocols already in place across the electricity sector and its position as the backbone to powering the wider economy means the renewables sector is uniquely positioned to drive a rapid economic recovery.

Solar Energy UK is confident that with the right stimulus and policy interventions the solar industry can benefit the UK recovery by creating thousands of local, high quality jobs, generating billions in direct and indirect GVA, and delivering on the Government’s net zero commitments. The solar industry offers local employment opportunities throughout its value chain, particularly through installations and maintenance which present great job creating potential across the whole of Wales.

The following high-impact recommendations have been developed through ongoing engagement with industry and are targeted to stimulate all segments of the solar and storage industries, including those which have been hardest hit by the lockdown restrictions. As a starting point, any sectoral support or stimulus from government should include robust conditionality requirements regarding net zero targets and the procurement of additional renewable generation capacity. 

Immediate Recovery Priorities

  1. Maximise Routes to Market and Improve Investor Confidence

Contracts for Difference: Implement a robust CfD design to maximise solar deployment, including sufficient Pot 1 budget, regular 6-monthly auctions, and no or adequately high capacity caps.

Multiple independent analyses, in addition to the Government’s own analysis, have concluded that it will not be possible to achieve net zero by 2050 with merchant projects alone. Solar generation capacity has the lowest technology costs and – despite lower loads factors than onshore and offshore wind – can offer much lower strike prices. Solar represents the lowest cost to the consumer throughout the CfD delivery years. It is therefore capable of delivering substantial additional capacity through this mechanism and can provide income to the CfD scheme to cross-subsidise other technologies, thereby diversifying the UK’s renewable generation mix further. The design, budget share, and administration of Pot 1 auctions should reflect the level of solar deployment required to meet net zero and the clear evidence that the solar industry can deliver the capacity needed at the lowest cost to consumers.

  1. Implement Green Tax Reform to Ensure Continued Sustainable Growth

Business rates: Except rooftop solar and storage from business rates.

Since 2017, businesses installing onsite solar have faced a 600-800% rise in business rates. The increase has prevented many installations in the C&I sector from going ahead due to the rates significantly reducing the savings solar affords and increasing payback periods. Excepting solar and storage from business rates, as gas CHP is, would stimulate SME investment in renewables once again. Battery storage will also pay business rates from the next revaluation, meaning businesses seeking to cut emissions through investing in smart technologies will be similarly penalised. High business rates will further deter the nascent onsite storage market, already facing tight economics and regulatory uncertainty risks, to the detriment of the UK’s leadership in smart technology.

  1. Support Innovation and Energy Efficiency to Improve UK Property Portfolio

New Build Properties: Implement high, ambitious new build minimum energy efficiency standards keeping to the timelines set out in the Future Homes Standard consultation.

The Welsh Government’s Building Regulations Part L and F is legislation that would see housebuilding standards substantially improved in 2025. It offers increased opportunities for the deployment of solar and improved energy efficiency measures in the new build market, minimising expensive retrofit measures in later years, benefiting households through lower running costs, and preparing supply chains for newer technologies. At a minimum, the Government should meet its ambitions of 75-80% uplift in energy by 2025. It is far more efficient and cost-effective to set high standards now, in comparison to the substantial long-term costs of inaction. The Government should not reduce efficiency ambitions in an attempt to support a short-term acceleration in housebuilding post-COVID-19.


How can the UK Government best-support the deployment of renewable generators in Wales?

The UK Government can best support the deployment of renewables in Wales by removing the systematic barriers which effect Wales’ energy transition.

Government should consider further support packages and policy improvement to enhance the role of renewable energy in their Industrial Strategy. Many of the medium to long-term priorities outlined below could be included in a solar sector deal, similar to those that have been announced for offshore wind, nuclear, and other energy industries.

  1. Ensure grid access and costs do not delay or prevent new deployment of renewables and storage:


Specifically, the Government must:

    1. Incorporate strong decarbonisation and flexibility requirements within the RIIO-ED2 framework.
    2. Enable cross-industry collaboration towards sharing grid reinforcement costs and reducing up front connection costs for developers, specifically through the Access and Forward-Looking Charges Significant Code Review.
    3. DNOs should collaborate across regions to implement standardised and transparent network costs, such as Assessment and Design fees.


  1. Power the Civil Estate with 100% renewables:


The Welsh and UK Government’s should work to ensure that 100% of the electricity demand of the Civil Estate is met through procuring additional renewable energy generation capacity. The target could require a minimum of 1GW of onsite renewables on Government estate as per shelved Government Solar PV strategy circa 2014. Power Purchase Agreements would allow for the deployment of additional renewable generation at no upfront cost to the Government. The Government should also consider adding supply to all publicly owned or publicly hosted EV chargers to local authority PPA scope, to ensure the EV transition is powered by clean renewable energy.

  1. Remove VAT for solar and storage technologies:


Since October 2019, residential properties installing solar and storage have been subjected to complicated VAT regulations, in some circumstances increasing VAT from 5% to 20%. All solar, storage installations (including maintenance to existing sites) should face 0% VAT to incentivise the uptake of domestic solar and smart technologies moving forward. This would significantly reduce the upfront cost to consumers.

  1. Reform network charging to support the deployment of embedded generation:


It is essential that regulatory reforms, such as Ofgem’s Network Access and Forward Looking Charging Review, be designed to incentivise renewables, zero-carbon storage and flexibility. Reforms made to date through the Targeted Charging Review have disproportionately impacted embedded generation and present a significant barrier to deployment which must be addressed to align with the shared objective of creating the resilient, flexible, and low carbon energy networks of the future. 

  1. Strengthen the UK’s commitment to carbon pricing:


A strong commitment to carbon pricing and clear price signals are essential to demonstrate the Government’s commitment to the energy transition, unlock access to capital, and ensure the cost competitiveness of renewable generation in the long term.

  1. Amend Ofgem’s remit to prioritise decarbonisation and grid flexibility:


Ofgem is moving in the right direction with the publication of their Decarbonisation Action Plan, however, more can be done to align the regulator’s remit with the Government’s net zero objectives. Ofgem needs to take a holistic, long-term view of the requirements of the energy sector to support the rapid decarbonisation and increased energy system flexibility which is essential to achieve the UK’s net zero emissions target. This would enable the network improvements necessary for consumers to benefit from the expansion of low-cost renewables and can be achieved with a new Strategy and Policy Statement from the Secretary of State for Business, Energy and Industrial Strategy, as per the Energy Act 2013.

  1. Develop skills programmes:


Any economic stimulus package must incorporate jobs training and reskilling programmes to support the levels of solar and storage deployment needed. There is currently a shortage of the skilled workers required to achieve the level of deployment needed to achieve net zero, and the solar industry is ready to work with government to develop and deploy education and training programmes to upskill the workforce and ensure the workforce necessary to deliver the energy transition is in place. The UK and Welsh Governments should look to work with the Green Jobs Taskforce to provide solutions to this skill shortage and ensure a sustainable pipeline of talent.
