The UK's energy sector continues to undergo significant change. The 2018 Renewable Energy Directive set a target for the UK to achieve 32 per cent of its energy consumption from renewable sources by 2030. The Energy Act 2013 (the Energy Act), initially enacted to achieve the target set by the 2009 Renewable Energy Directive, implemented key aspects of Electricity Market Reform (EMR) – a policy initiative pioneered by the UK government to mobilise £110 billion of capital investment required by 2020 to ensure a reliable and diverse supply of low-carbon electricity. Reforms such as these are vital, as the UK has seen significant power plant closures in recent years; the Energy Act was aimed at ensuring both investment in infrastructure, alongside decarbonisation as more power plants are decommissioned in the UK.
The UK is one of the first major economies to set a legally binding target to reduce emissions to net zero by 2050. The target came into force on 27 June 2019. The Committee on Climate Change advised in a report dated 2 May 2019 that the UK could require up to four times the amount of renewable generation available at today's levels, complemented by firm low-carbon power options such as nuclear power and carbon capture and storage (applied to biomass or gas-fired plants) to achieve its net zero emissions target. In an effort to promote private investment in the development of large-scale infrastructure projects (and, in particular, the development of low-carbon technology) in the UK, the UK government has instituted a series of programmes that are specifically designed to stabilise the economics of financing for such projects.
II THE YEAR IN REVIEW
The UK's current electricity mix has changed substantially, and rapidly, over the past few of years. Most notable is a continued increase in renewable-generated electricity (a trend in line with global patterns). In 2017, for the first time, Britain generated more electricity from renewable energy than from gas and coal and this trend has continued over the past few years. Renewable sources (wind, solar, hydro and biomass) together contributed just over 36.9 per cent of electricity generation in 2019, up from 33 per cent in 2018, with 119TWh of electricity generated from renewable sources, largely as result of increased capacity. The Energy Trends report, published by the UK Department for Business, Energy and Industrial Strategy (BEIS) in March 2020, reported that renewable electricity capacity was 47.4GW at the end of 2019, a 6.9 per cent increase on 2018. Notably, around half of this increase in capacity was in offshore wind.
During November 2016, the government published its plan to upgrade UK energy infrastructure, reaffirming its commitment to spend £730 million of annual support on renewable electricity projects, also setting out proposals for the next steps to phase out electricity generation from unabated coal-fired power stations within the next decade. This long-term plan is intended to provide confidence to investors that the UK is open to investment in new, cleaner energy capacity.
The third allocation process for the Contract for Difference (CfD) scheme took place in 2019. The government secured nearly 5.8GW of new capacity, which will increase the overall renewable CfD capacity by 60 per cent. Offshore wind was the biggest winner in this round, with six new offshore wind projects securing 5.47GW of contracts (of which 3.6GW of contracts were awarded to SSE and Equinor) representing 95 per cent of the capacity awarded, which will increase the role of offshore wind in achieving the net zero carbon emissions target by 2050. The auction has cleared at the record low price of £39.650/MWh for delivery year 2023/24 and £41.611/MWh in 2024/25.
The fourth CfD allocation round is currently planned for 2021. At the time of writing, it is anticipated that the auction will be open to both established technologies (known as Pot 1 technologies – onshore wind, solar PV, waste to energy with combined heat and power (CHP), hydro, coal-to-biomass conversions, landfill gas and sewage gas) and less-established Pot 2 technologies (offshore wind, remote island wind, wave, tidal steam, advanced conversion technologies, anaerobic digestion, dedicated biomass with CHP and geothermal). Onshore wind, solar PV and energy from waste with CHP will once again be eligible to take part in the CfD auction. The government emphasised that to meet net zero emissions by 2050 it continues to view offshore wind as being strategically important and may therefore establish a third separate pot for offshore wind, removing the technology from Pot 2, which would allow more appropriate parameters (e.g., monetary budget, capacity cap, delivery years) to be set for this Pot 3. The government is also seeking generators' views as to the storage solutions they would wish to co-locate with CfD projects over the lifetime of the CfD contract, raising the prospect that the CfD regime may in the future facilitate the co-location of electricity storage with CfD projects.
In June 2016, the UK voted to leave the European Union. Since then, the Conservative government has been negotiating with the EU, and has tabled the European Union (Withdrawal) Bill, which will replace the European Communities Act 1972 and make other provisions in connection with the withdrawal of the UK from the EU. It is the primary piece of legislation that will determine the UK's position in relation to current EU legislation post-exit. It also aims to remove the jurisdiction of the European Court of Justice over the UK courts. It will transfer all current EU law into UK domestic law, so that as smooth a transition as possible is achieved in the immediate aftermath of exiting the EU. It is seen as 'one of the largest legislative projects ever undertaken in the UK' by the House of Commons. In addition to the legislative overhaul and regulatory uncertainty, the vote to leave the EU creates uncertainty over the continued access of the UK to European Investment Bank funding, which until the vote had been an important source of funding for smaller-scale UK projects. During the transition period, it is likely that the UK will continue to be subject to EU procurement directives (such as the Public Contracts Regulations 2015 SI 2015/102). This means that organisations under the rules must continue advertising and awarding public contracts in accordance with the EU directives. It is unclear what the position will be regarding procurement post-exit and post-transition period.
III THE POLICY AND REGULATORY FRAMEWORK
i The policy background
Ofgem E-Serve administers several environmental schemes and consumer and social programmes on behalf of the government, including schemes related to renewable energy.
Introduced on 1 April 2010, the Feed-in Tariffs (FIT) scheme was a government programme designed to promote the uptake of small-scale renewable and low-carbon electricity generation technologies. The FIT scheme was available for solar photovoltaic, wind, micro combined heat and power, hydro or anaerobic digestion technology up to a capacity of 5MW, or 2kW for micro combined heat and power. The FIT scheme closed to new generation capacity from 1 April 2019.
The provision of CfDs is intended to stabilise revenues for investors in low-carbon electricity generation projects such as renewables by helping developers secure the large upfront capital costs for low-carbon infrastructure. The CfD is a quasi-power purchase agreement. Generators with a CfD will sell their electricity into the market in the normal way and remain active participants in the wholesale electricity market. The CfD then pays the difference between an estimate of the market price for electricity and an estimate of the long-term price needed to bring forward investment in a given technology (the strike price). When a generator sells its power, if the market price is lower than needed to reward investment, the CfD pays a top-up. However, if the market price is higher than needed to reward investment, the contract obliges the generator to pay back the difference. In this way, CfDs stabilise returns for generators at a fixed level for the duration of the contract. This removes the generator's long-term exposure to electricity price volatility, substantially reducing the commercial risks faced by these projects. The Energy Act includes a provision whereby a new UK government-owned company (the Low Carbon Contracts Company, or LCCC) will act as the counterparty to eligible generators under the CfD. This mechanism was in direct response to concerns about the 'credit' behind the CfD economics. Although a CfD is a private law contract between a low carbon electricity generator and the LCCC, the cost of CfDs will ultimately be met by consumers via a levy on electricity suppliers. The latest CfD round took place in 2019. BEIS announced the fourth round for 2021 with further rounds to be held every two years thereafter.
The Renewable Obligation (RO) scheme is one of the main support mechanisms for large-scale renewable electricity projects in the UK. Smaller-scale generation is mainly supported through the FIT scheme. The RO came into effect in 2002 in England and Wales, and Scotland, followed by Northern Ireland in 2005. The scheme places an obligation on UK electricity suppliers to source an increasing proportion of the electricity they supply from renewable sources. The RO scheme closed to all new generating capacity on 31 March 2017.
The Climate Change Levy (CCL) was introduced in 2001 and is a tax on UK business, collected by energy suppliers, designed to encourage energy efficiency, reduce carbon emissions and promote energy from renewable sources. Businesses were previously able to claim an exemption if they could show a levy exemption certificate, showing that they bought energy from qualifying renewable energy sources. In the July 2015 budget, the UK government announced the removal of CCL exemption for electricity generated from renewable sources from 1 August 2015.
The Offtaker of Last Resort (OLR) is a government scheme that aims to promote the availability of power purchase agreements (PPA). It is intended as a last resort to help renewable generators who cannot get a PPA through the usual commercial means. The OLR scheme is part of the government's wider programme on EMR.
ii The regulatory framework
The Department of Energy and Climate Change (DECC), formed in 2008, was the ministerial department responsible for making decisions, setting policy and implementing legislation affecting the electricity sector. The corresponding government ministry in Northern Ireland was the Department of Enterprise, Trade and Investment. Following the EU Referendum held on 23 June 2016, DECC was merged with the Department for Business and Innovation to create BEIS (the corresponding government ministry in Northern Ireland is the Department for the Economy).
BEIS works closely with and is supported by other agencies and public bodies, including the Gas and Electricity Markets Authority (GEMA) and the Office of Gas and Electricity Markets (Ofgem).
GEMA has primary responsibility for regulation of the energy sector. GEMA's powers and duties are largely provided for in statute (such as the Gas Act 1986, the Electricity Act 1989, the Utilities Act 2000, the Competition Act 1998, the Enterprise Act 2002 and the Energy Acts of 2004, 2008, 2010 and 2011), as well as arising from directly effective European Community legislation. GEMA's principal objective is to protect the interests of existing and future consumers in relation to gas conveyed through pipes, and electricity conveyed by distribution or transmission systems. The interests of these consumers are their interests taken as a whole, including their interests in the reduction of greenhouse gases, and in the security of the supply of gas and electricity to them. GEMA is constituted of individuals who are appointed by the Secretary of State for specified terms of not less than five years.
GEMA delegates its functions to Ofgem and provides it with strategic direction and oversight. Ofgem is also a non-ministerial government department and an independent national regulatory authority recognised by EU directives. Ofgem states that its principal objective is to protect the interests of existing and future electricity and gas consumers. Ofgem E-Serve, which introduces itself as the 'delivery arm of Ofgem', administers environmental schemes and consumer and social programmes on behalf of the government, including schemes related to renewable energy such as the FIT scheme, CfDs, RO, the CCL and the OLR scheme (see Section III.i for more details).
The Environment Agency is responsible for protecting and improving the environment, as well as promoting sustainable development. The role of the Environment Agency regarding electricity is limited to matters related to pollution and therefore mainly relates to conventional generation and nuclear energy.
The Energy Act (together with secondary legislation) implements key aspects of electricity market reform and is a policy initiative pioneered by the UK government to mobilise £110 billion of capital investment required by 2020 to ensure a reliable and diverse supply of low-carbon electricity. This is the applicable regulatory framework for the developing, financing, operating and selling of power and environmental attributes from renewable projects, and the regulation of CfDs.
The RO scheme has created a market for the sale of environmental attributes. Through the RO scheme, the government places an annual obligation on licensed electricity suppliers to source a proportion of the electricity they supply to customers from renewable energy sources. These suppliers are required to meet their individual obligation target by purchasing Renewable Obligation Certificates (ROCs) from renewable generators directly, from the ROCs market or by paying a set amount to government by way of a penalty. Through this mechanism, ROCs have a monetary value (the buyout price for the 2019–2020 ROCs is £48.78 per ROC) and generators have been able to sell (among other things) the electricity generated by their renewable generating stations (and associated ROCs) to licensed electricity suppliers.
A generation licence is required for the sale of electricity and this stipulates compliance with the relevant industry codes. In particular, all licence holders (for example, transmission, generation, supply and distribution) must be registered within the Balancing and Settlement Code. Certain environmental, health and safety, and electricity quality measures must also be in place for the construction and operation of systems that generate and supply electricity (Electricity, Safety, Quality and Continuity Regulations 2002 (as amended)); these will depend on the relevant renewable project in question.
IV RENEWABLE ENERGY PROJECT DEVELOPMENT
i Project finance transaction structures
As with all energy and infrastructure projects, the financing structure for renewable energy projects depends on the nature of the client and the type of project. In a straightforward project, for example, the funding may come from a combination of equity investment or debt finance (including in some cases, mezzanine finance), through a single lender or multiple lenders and on a non- or limited-recourse basis. Senior lenders can include commercial banks familiar with project financings, export credit agencies, multilaterals such as the European Investment Bank or the International Finance Corporation.
Private equity funds may be willing to take construction risk and provide additional funding ranking senior to pure equity, which can be contributed at a senior or mezzanine level (depending on the particular project).
Where there are unproven technologies or other uncommon risks that traditional financiers are not willing to take, or where the use of traditional project financing would prove too expensive, certain other sources of funding have been available, such as the EU NER300 fund, direct grants from the government and, in Scotland, the Renewable Energy Investment Fund administered by the Scottish Investment Bank.
Once the 'risky' construction phase period has ended and projects are operational, further financing structures become available in addition to those described above. Examples of these are refinancing of construction-phase bank financings by way of capital market instruments and institutional investors such as pension and insurance funds, who do not customarily have an appetite for construction risk, but who look favourably at long-term debt financings with proven and stable cash flows.
In domestic UK project financings, the intention of the parties (and the usual requirement of all types of lenders) is to create security over all, or substantially all, of a project company's assets. Project finance borrowing vehicles are normally special purpose vehicles (SPVs) with no pre-existing businesses, rights or liabilities beyond those associated with the project. Security is normally granted by way of a general security agreement, such as a debenture, which covers all the SPV's rights and assets (both pre-existing and after-acquired) or (less commonly) by way of separate security agreements for each type of asset. Lenders will look to achieve 'going concern' security on a UK-based project or asset. This is aimed at putting them in a position of default, stepping in if necessary and operating (or selling) the relevant asset as a going concern. Basic legal security is normally insufficient to achieve this type of outcome; conventional legal security is often supplemented by bespoke contractual arrangements providing lenders with specific notice, 'cure' and 'step-in' rights. Where (as is very often the case) the viability of a project as a going concern is dependent upon the continuing availability to an operator or owner of permits and licences, special attention will need to be paid to the consequences of default in the wider sense – by way of example, breach of licence conditions or change of control can result in permits and licences being breached or becoming terminable. Certain types of licences and permits are, in effect, personal to the initial licence holder; contractual rights can be expressed to be non-assignable in the absence of consents. A careful analysis of the regulatory and practical conditions applicable to the application for, and maintenance of, permits, licences and key contracts is necessary and will differ on a case-by-case basis.
The main types of securities under English law are mortgages (equitable and legal), charges (fixed and floating), assignments (broadly equivalent to charges), pledges and liens. Mortgages, charges and assignments are the most frequently used forms of security. Assignments may be legal or equitable; the process for enforcement of the two types of security differs. A debenture will include a range of mortgages, charges and assignments depending on the nature of the security assets. Debentures can create legal mortgages and fixed and floating charges over all the borrower's assets, if agreed, and as set out in the debenture. The debenture is executed as a deed.
ii Distributed and residential renewable energy
Underpinned by general environmental concerns, technological innovation and government policy, the growth of on-site distributed generation projects has been noticeable in recent years. In particular, an uptake in residential use has been seen, with very small-scale projects operated and maintained by residential end users evident across the country. Similarly, businesses and public sector institutions continue to install their own generation projects, whether that be high-street stores, office blocks or public-sector services buildings, such as hospitals.
The types of technologies seen in the residential sector include solar photovoltaic panels, small wind turbines, natural-gas-fired fuel cells and emergency backup generators. In the commercial and industrial sectors, the same technologies exist in addition to hydropower, biomass combustion, municipal solid waste incineration, natural gas or biomass-fuelled fuel cells and reciprocating combustion engines. The uses of such distribution generation projects and the ownership and offtake structure depend largely on the user and their needs. For example, if a hospital has a system, it will seek high reliability and thus high quality, perhaps at the expense of cost. On the flip side, industrial plants may prioritise a low-cost system over other factors.
Recently, microgrids have emerged as part of a number of solutions for the UK's transition from a conventional energy system to one fit for the 21st century and beyond, responsive to changing needs and desires, namely the pursuit of low-cost, efficient energy that has minimal environmental impact. The UK government in particular has encouraged microgrids because, as they work locally, they can be disconnected from the national grid to operate independently where necessary. The importance of their independence cannot be understated, namely because, in the event of a disturbance, microgrids can be isolated to minimise greater disruption. For that reason, they are an attractive option for small communities. An example of a scheme is the Flexible Plug and Play initiative, introduced in 2012. This three-year programme delivered cheaper and faster distributed generation connections, as well as enabling such distribution schemes to become active, where previously they were thought to be unfeasible.
The nature of distributed generation is that it allows for self-consumption, offering significant consumer benefits in terms of economics. However, it is particularly important in this context that consumers fully understand the legal backdrop of any electricity generated, especially if they intend to sell the excess electricity generated. Not only is compliance with the applicable regulations imperative, but there are a number of agreements and contracts that need to be put in place by the distributor, meaning in the residential sector legal and professional advice must be sought, adding to expense. In terms of property rights, it may be advisable for those involved to ensure they are sufficiently protected by obtaining options for leases and options for easements. In addition, the effect of Brexit is unknown, and this uncertainty has a particular impact on distributed generation, an area partially regulated by the European Union.
Energy storage is a key part of the UK government's plan to achieve net zero emissions targets, whether as stand-alone projects or co-location with new or retrofitted generation projects. Over 1GW of battery storage planning applications were made in the UK in 2019 (compared with 6,900MW in 2018). These storage projects consist in the majority of lithium-ion battery, lead-acid battery, open-loop pumped hydro storage, closed-loop pumped hydro storage and modular compressed storage. Electricity storage is treated as a form of electricity generation and, as such, the applicable legal framework to electricity storage is currently the same as that applicable to electricity generation.
In June 2019, Ofgem announced clarifications to the regulatory framework applicable to energy storage with changes to the electricity generation licence standard conditions to include a definition of storage and storage facility and ensure storage providers are not subject to final consumption levies. The classification of electricity storage as generation (and therefore the application of the legal framework applicable to generators) has been seen to be a significant hurdle to the development of energy storage projects in the UK; this has been acknowledged by Ofgem, which has committed to work together with the government to provide greater regulatory clarity. Some of the key concerns are that certain licensed operators, such as distribution licence holders, are restricted from holding a generation licence and therefore from operating electricity storage. Following a consultation in 2019, BEIS announced a proposal to change planning regulations to carve out electricity storage, except pumped hydro, from the Nationally Significant Infrastructure Projects regime in England and Wales. Under the proposals, this type of storage would generally be subject to consent from the relevant local planning authority in England and Wales.
iii Non-project finance development
In the UK, the divide between conventional project finance and the bond and leveraged finance markets continues to narrow. The market saw a continuation of diversification of both sources and types of project-related debt. As with the project bonds market, the trend comes in part from the United States; 2018 saw a number of infrastructure and energy sponsors experimenting with Term Loan B structures – sometimes as refinancing tools, sometimes to sit alongside conventional financings or less conventional financings – for example, inventory and receivables financings.
There are no legal requirements that apply exclusively to project companies seeking to issue bonds or similar capital markets instruments. Any project company seeking to issue debt instruments (securities) on the London Stock Exchange (LSE) must comply with the Listing Rules of the UK Listing Authority (UKLA) (the Listing Rules). The UKLA, a division of the Financial Conduct Authority, is the body responsible for regulating all securities listed on the LSE. The Listing Rules contain (1) the rules and regulations for listing debt securities, and (2) the continuing obligations that apply to issuers and bondholders for the duration of the listing. The Listing Rules cover principles ranging from corporate governance and executive remuneration to accounting standards and full disclosure of information to prospective investors. Debt securities admitted to the Main Market of the LSE must be listed in accordance with Chapters 2 and 17 of the Listing Rules. Debt securities admitted to the Professional Securities Market must be listed in accordance with Chapter 4. All debt securities admitted to trading must comply with the LSE's Admission and Disclosure Standards and the relevant Disclosure and Transparency Rules.
Rules may differ according to the issuer's market sector. Rules may also differ according to the issuer's investor base. For example, an issuer will be subject to more stringent obligations if marketing its securities to retail investors as opposed to solely professional investors.
V RENEWABLE ENERGY MANUFACTURING
As the EU is a customs union, UK companies can buy most goods from other member countries without restrictions – although VAT and excise duty will normally still apply. If a UK company imports from outside the EU, it may have to comply with import licensing requirements and with common customs tariffs that apply across the EU. Apart from the general restrictions concerning materials that are deleterious to health and safety and the environment, there are no legal restrictions or controls that apply exclusively to importing construction equipment. It is not yet known whether the UK will remain part of the EU Customs Union following the UK's exit from the EU on 31 December 2020.
VI CONCLUSIONS AND OUTLOOK
The Conservative government expects that total public and private investment in the sector will exceed £600 billion by 2027. Already, public and private infrastructure investment has gradually increased over the past three decades (since 2010, 4,500 infrastructure projects have been delivered). The two largest sectors, energy (which boasts investment of £191,338.5 million from 2017/2018 to 2020/2021) and transport (£135,276.9 million from 2017/2018 to 2020/2021), account for 70 per cent of the infrastructure pipeline's total value.
The UK government's commitments under the Paris Climate Agreement and a binding net zero emissions target by 2050, coupled with the political and legislative uncertainty resulting from the UK's referendum vote to exit the EU, are likely to be the biggest drivers of change in the renewables energy market in the short and medium term.
At the time of writing, the impact of the covid-19 pandemic on renewable energy projects in the UK remains unclear. In the short term, construction-stage projects are likely to be impacted by travel restrictions and supply chain disruptions, with potential delays to the start of commercial operation. Lenders will continue to closely monitor the impact of delays on their financings. It is currently unclear how the pandemic will affect the development of new renewable projects.
