Ofgem publish update to Targeted Charging Review proposals

In the meantime, the regulator has released a letter detailing guidelines on residual charging proposals and renewables modelling.

Residual charging proposals

In the ‘minded-to’ consultation, published in November 2018, Ofgem proposed two leading options for reform for residual electricity network charges. The options were; a fixed charge, or an agreed capacity charge. Ofgem indicated that they preferred a fixed residual charge.

Most respondents to the consultation also expressed support for the fixed charge. However, there was some disagreement with the structure of the proposal, predominantly with user segments associated with this pricing option.

Some respondents expressed that the fixed charges should take more account of the diversity of non-domestic users, pointing out that individual bands could contain a wide range of different user sizes. It was also highlighted that Ofgem’s proposed basis for segments could be seen as arbitrary.

In light of this feedback, Ofgem’s refined proposal for non-domestic customer segmentation is that:

  • total allowed residual revenue would first be apportioned between voltage levels, on the basis of net volumes, as set out in the November 2018 minded-to consultation;
  • non-domestic segment boundaries would be set in terms of agreed capacity levels for users at higher voltages where this data is widely available, and net volume levels at Low Voltage (LV). This is in place of segmenting these users on the basis of the line-loss factor classes (as set out in the November minded-to consultation).

Ofgem has identified five national level charging bands for Low Voltage non-domestic users and five each for High Voltage (HV) / Extra High Voltage (EHV) non-domestic users. The banding is the same for HV and EHV customers, but their share of the residual charges is calculated at voltage level resulting in fifteen charges in total.

The refined band thresholds would be applied on a consistent basis across the country. Users would be allocated on a historic basis and updated in line with price controls. Incentives are expected to be reduced in a bid to change behaviour in response to residual changes.

The option for agreed capacity has been left open by Ofgem. The regulator has stated that where more users collect agreed capacity data there could be the opportunity to transition charges to an agreed capacity or more appropriate basis.

The Targeted Charging Review

EIC has a more detailed breakdown of the Targeted Charging Review that can be read here.

An update on Smart Export Guarantee

The Department of Business, Energy and Industrial Strategy (BEIS) has published a response to their consultation on the future for small-scale low-carbon generation, which sought views on policy proposals for a Smart Export Guarantee (SEG).

The SEG will require suppliers with at least 150,000 domestic customers to provide a minimum of one tariff offer to small-scale low-carbon generators. Exporters of up to 5MW capacity of anaerobic digestion, hydro, micro-combined heat and power, onshore wind, and solar photovoltaics are eligible for payment.

It is the government’s opinion that small-scale low-carbon electricity generation should be supported by competitive, market-based solutions. To this effect, the government will not specify a minimum tariff rate in order to allow the market to develop. However, a supplier must provide payment greater than zero at all times of export.

The SEG is a replacement for the Feed-in Tariff (FiT), which closed to new generators in March 2019. The Feed-in Tariff scheme was originally introduced in April 2010 in order to incentivise the development of small-scale renewable generation from decentralised energy solutions. Generators were paid a fixed rate determined by the Government, which varied by technology and scale.

How will this impact you?

All suppliers that meet the SEG criteria will be required to offer at least one tariff by an expected date of 31 December 2019, providing small-scale generators with a choice of who they want to export to.

Currently, there are very few suppliers that offer tariffs of this nature. However, as the deadline approaches it can be expected that all larger suppliers will begin to offer their own options, allowing generators to choose the best tariff for themselves.

Energy Policy Dates for 2019

As we look ahead to 2019, we’ve outlined key energy industry changes and dates to take action by.

EU ETS – Market Stability Reserve (MSR)

1 January – MSR Implementation

The European Commission is introducing a solution to the oversupply of allowances in the carbon market, which will take effect in January.

EU carbon allowances, or European Allowances (EUAs) serve as the unit of compliance under the European Emissions Trading Scheme (EU ETS). In response to a build-up of these allowances, following the 2008 global financial crisis, the European Commission has introduced a long-term solution known as the Market Stability Reserve (MSR). With Brexit looming, there’s uncertainty as to whether these changes will affect the UK.

 

Energy Price Cap

1 January – Price Cap implementation

Price protection for 11 million customers on poor value default tariffs will come into force on 1 January 2019. Ofgem has set the final level of the price cap at £1,136 per year for a typical dual fuel customer paying by direct debit.

When the price cap comes into force suppliers will have to cut the price of their default tariffs, including standard variable tariffs, to the level of or below the cap, forcing them to scrap excess charges. The cap will save customers who use a typical amount of gas and electricity around £76 per year on average, with customers on the most expensive tariffs saving about £120. In total, it is estimated that the price cap will save consumers in Great Britain around £1 billion. Read more here.

 

Ofgem’s Targeted Charging Review (TCR) – the end of Triad season?

4 February – Consultation conclusion

Ofgem has launched a consultation, due to conclude on 4 February 2019, into how the costs of transporting electricity to homes, public organisations, and businesses are recovered. Proposed changes could remove the incentive for Triad avoidance.

Costs for transporting electricity are currently recouped through two types of charges:

  • Forward-looking charges, which send signals to how costs will change with network usage
  • Residual charges, which recover the remainder of the costs

In order to ensure that these costs are shared fairly amongst all users of the electricity network, Ofgem are undertaking a review of the residual network charges, as well as some of the remaining Embedded Benefits, through the Targeted Charging Review (TCR). Ofgem are exploring the removal of the Embedded Benefit relating to charging suppliers for balancing services on the basis of gross demand at the relevant grid supply point. This is important as it would eliminate the incentive of Triad avoidance.

 

Brexit

29 March – Scheduled date to leave the EU

Whilst not a specific energy policy announcement, the UK’s departure from the EU is a significant event that has raised a lot of questions concerning UK energy security.

We put together a Q&A on how Brexit may impact the UK energy industry and climate change targets. Read more here.

 

Closure of the Feed-in Tariff (FiT) scheme

31 March – Scheme Closes

The Government has confirmed plans to remove the export tariff for solar power, which currently provides owners of solar PV panels revenue for excess energy that they generate. This will coincide with the closure of the Feed-in Tariff (FiT) scheme.

The FiT scheme was introduced in April 2010 in order to incentivise the development of small scale renewable generation from decentralised energy solutions such as solar photovoltaics (PV), wind, hydro, anaerobic digestion and micro Combined Heat and Power (CHP). Generators were paid a fixed rate determined by the Government, which varied by technology and scale.

The scheme will close in full to new applications from 31 March 2019, subject to the time-limited extensions and grace period.

 

Streamlined Energy and Carbon Reporting (SECR)

1 April – SECR implementation

Streamlined Energy and Carbon Reporting (SECR) is on the way, due to come in to effect from 1 April 2019. The introduction of this new carbon compliance scheme aims to reduce some of the administrative burden of overlapping schemes and improve the visibility of energy and carbon emissions when the CRC scheme ends.

EIC can help you achieve compliance. Read more about Streamlined Energy and Carbon Reporting (SECR) by clicking here.

 

UK Capacity Market

Early 2019

The UK Capacity Market is currently undergoing a temporary suspension, issued by the European Court of Justice (ECJ), on the back of a legal challenge that the auction was biased towards fossil fuel generators.

The ECJ’s decision means that payments made under the Capacity Market (CM) scheme will be frozen until the UK Government can obtain permission from the European Commission to continue. In addition, the UK will not be allowed to conduct any further CM auctions for energy firms to bid on new contracts.

The UK government has since iterated that it hopes to start the Capacity Market as soon as possible and intends to run a T-1 top-up auction next summer, for delivery in winter. This is dependent on the success of a formal investigation to be undertaken by the European Commission early in the New Year.

 

Spring Statement and Autumn Budget

The UK Government’s biannual financial updates are always worth looking out for.

The Spring Statement will be delivered in March and the more substantial Autumn Budget is scheduled for October. The 2018 budget had a very heavy focus on Brexit, with very little to say concerning energy policy. It is likely this will be the case for the Spring Statement and potentially going forward.

 

Energy Savings Opportunity Scheme (ESOS)

5 December – ESOS Phase 2 compliance deadline

ESOS provides a real chance to improve the energy efficiency of your business, on a continual basis, to make significant cost savings.

In Phase 1 of ESOS we identified 2,829 individual energy efficiency opportunities, equivalent to 461GWh or £43.9m of annual savings across 1,148 individual audits. Our team also helped over 300 ESOS Phase 1 clients avoid combined maximum penalties of over £48million.

With EIC you can achieve timely compliance and make the most of any recommendations identified in your ESOS report.

Government confirms closure of Feed-in Tariff

The Government has confirmed plans to remove the export tariff for solar power, which currently provides owners of PV panels revenue for excess energy that they generate. This will coincide with the closure of the Feed-in Tariff (FiT) scheme.

Though a large proportion of respondents to the governmental consultation disagreed with the plans, the Department for Business, Energy and Industrial Strategy (BEIS) has decided that both the Feed-in Tariff subsidy scheme and the export tariff will close to new participants after March next 2019.

 

What was the Feed-in Tariff (FiT) scheme?

The Feed-in Tariff scheme was introduced in April 2010 in order to incentivise the development of small-scale renewable generation from decentralised energy solutions such as solar photovoltaics (PV), wind, hydro, anaerobic digestion, and micro Combined Heat and Power (CHP). Generators were paid a fixed rate determined by the Government, which varied by technology and scale.

Payments to the small-scale generators were made quarterly by FiT-licensed suppliers and recovered from all consumers. A levelisation process also took place every quarter, as not all suppliers were required to offer FiTs and their exposure to the scheme varied.

 

The Government response

The response from the Government argues that the closure of the FiT scheme represents their “desire to move towards fairer, cost reflective pricing and the continued drive to minimise support costs on consumers”, adding that the current scheme does not support the vision set out in either the Industrial Strategy or the Clean Growth Strategy.

The scheme will close in full to new applications from 31 March 2019, subject to the time-limited extensions and grace period.

The Government has decided to provide a 12-month grace period for “Renewals Obligation Order Feed-In Tariff (ROO-FiT) scale” (all hydro and anaerobic digestion, solar PV, and wind with a declared net capacity over 50kW) installations that apply for preliminary accreditation on or before the cut-off date, are accepted into the cap, and then suffer grid and/or radar delay beyond their control. This means they are unable to accredit during their preliminary accreditation validity period.

It’s also been decided that projects in oversubscribed deployments caps at the close of the scheme will not be eligible for either generation or export tariff payments under the scheme, and so Ofgem will not grant them preliminary or full accreditation.

 

How will this impact you?

The results of these closures will mean that anyone that adds solar generation from April 2019 will not be paid for any excess power that is exported to the grid. These changes will not affect the circa 800,000 homes that have already solar panels fitted since the Feed-in Tariff scheme launched in 2010.

The Government is reportedly preparing to announce a market-based replacement to the export tariff early in the New Year, which would see new rules on how suppliers could purchase the excess power.

However, there will likely be a gap between the closure of the Tariff and the implementation of any new plans, meaning any new solar generators will be affected during this time.

Targets for 2019/20 Renewables Obligation published

The Department for Business, Energy and Industrial Strategy (BEIS) has published the Renewables Obligation (RO) for 2019/20, which will bring an estimated cost increase to consumers of £2.21/MWh.

The Renewables Obligation is the main financial mechanism by which the Government incentivises the building of large-scale renewable electricity generation. Ofgem issues Renewables Obligation Certificates (ROCs) to generators in relation to the amount of eligible renewable electricity they produce.

Generators sell these ROCs to suppliers or traders, which allows them to earn a premium in addition to the wholesale electricity price received for the electricity generated.

BEIS has outlined that electricity suppliers will need to produce 0.484 ROCs per MWh during this financial year across England, Scotland, and Wales.

This marks an increase of 3.4% from the 2018/19 Obligation, which was 0.468 ROCs per MWh. The new targets translate to an increase in the cost to consumers of an estimated £2.21/MWh from current levels.

 

Exemption for Energy Intensive Industries

BEIS established an exemption for Energy Intensive Industries (EIIs) from up to 85% of the indirect costs of the RO in 2017. This was implemented in England and Wales, then subsequently by the Scottish Government, meaning that under current arrangements there is a single obligation level for Great Britain.

The exemption means that the obligation level applies to:

  • 100% of electricity supplied to non-EIIs
  • 15% or more of the electricity supplied to EIIs

 

ROCs for biomass

New to the Renewables Obligation Order is the introduction of annual flexible caps on the number of ROCs that certain RO-eligible biomass co-firing and conversion units can receive.

The new regulation will define two types of generating stations – ‘capped’ and ‘mixed’ – to which the flexible cap mechanisms will apply. These stations will be subject to a different amount of ROCs that can be assigned.

Capped generating stations comprise only of non-grandfathered ‘capped’ units, whilst mixed generating stations comprise of these and also grandfathered ‘exempt’ units. A grandfathered unit is one that has a policy commitment to receive no less support under the RO than they have received historically. The cut-off date for grandfather biomass units was 12 December 2014. Any units that generated at the biomass conversion band after this date are not grandfathered.

At capped stations, there is a limit on the number of ROCs that the station can be issued in an Obligation year, equal to 125,000 ROCs for each unit at the station.

At mixed stations, an overall cap will be calculated by adding an allowance of 125,000 ROCS for each of the stations’ capped units to an estimate of the number of ROCS likely to be issued for generation at the exempt units during the Obligation year.

Currently, only Drax Power Station in Selby meets the BEIS definition of a mixed generating station for 2018/19.

What impact will Brexit have on UK climate change targets?

The energy sector in the UK had already seen significant changes with the Energy Act 2011 and various proposals for reform of the electricity market. The potential impacts of Brexit on the UK and global economy could be far-reaching. However, the direct impact on the energy industry is likely to be more muted.

 

How will Brexit impact on the carbon market and the EU ETS?

The Government has published plans for the implementation of a UK carbon tax in the case of a ‘no-deal’ Brexit.

Under a ‘no-deal’ scenario, the UK would be excluded from participating in the EU Emissions Trading Scheme (ETS). This would mean current participants in the EU ETS who are UK operators of installations will no longer take part in the system.

In this instance, the UK Government will initially meet its existing carbon pricing commitments through the tax system. A carbon price would be applied across the UK, with the inclusion of Northern Ireland, starting at £16/tCO2, marginally less than the current EU ETS price, maintaining the level of carbon pricing across the UK economy post-Brexit.

The tax would be applied to the industrial installations and power plants currently participating in the EU ETS from 1 April 2019.

The House of Commons Business, Energy and Industrial Strategy (BEIS) Committee has strongly recommended remaining in the EU ETS at least until the end of Phase III in 2020.

The UK’s 5th carbon budget, adopted in 2016, assumes continued participation in the EU ETS, and will need to be altered if the UK leaves the EU ETS.

 

Will Brexit affect the UK’s climate change targets?

The UK’s climate change targets are expected to continue unaffected by whatever Brexit deal is reached. The Climate Change Act 2008 established that such goals are undertaken on a national level.

However, there are several international issues in this area which will need to be settled. The UK’s emissions reduction target forms part of the EU target under the Paris Agreement and this will need to be withdrawn. The UK would also need to submit its own Nationally Determined Contribution under the United Nations Framework Convention on Climate Change (UNFCCC) processes.

 

What about renewable energy?

After Brexit, the UK will no longer be obligated by renewable energy targets as part of the EU Renewable Energy Directive. Additional freedom from State Aid restrictions has the potential to allow the Government to shape renewable energy support schemes.

The development of large-scale projects may be impacted by the availability of funding from EU institutions such as the European Investment Bank (EIB). However, renewable and low-carbon energy will remain a focal point of UK energy policy post-Brexit, with national and international decarbonisation obligations unaffected by their relationship with the EU.

As part of the European Union (Withdrawal) Act 2018, EU legislation will be initially transposed into UK law from 29 March 2019. For some elements of the EU law, the UK will need to reach an agreement with the EU in order to maintain the status quo.

The role of renewables this winter

The increase in wind and solar capacity in recent years has contributed to the overall reduction in demand. Higher volumes of on-site renewable capacity allow more generation to be provided off-grid, as homes and businesses generate their own electricity supply during windy or sunny spells.

This reduces demand on the national transmission system. The high levels of solar availability during the summer season were a particularly strong influence on demand levels this year, as on-site solar panels increased embedded generation, reducing demand requirements for the transmission network.

During stormy weather conditions, installed wind capacity can now provide around 12GW of electricity to the grid. Average wind generation in the UK last month was 5.3GW a day; over 50% higher than in September 2017.

 

average wind

 

What happens when there’s no wind?

While high winds can reduce power demand, one of the biggest dangers to the National Grid electricity network is a high-demand scenario at a time when wind output is very low. Lighting has a bigger impact on electricity demand than heating, as the majority of home heating is gas-fired.

However, during severe cold periods, electricity demand does spike as additional electric heating is needed to cope with the very low temperatures. This scenario occurred during March as a result of the Beast from the East, when peak demand jumped around 10% as temperatures dropped. The cold snap also brought very high winds to the UK. Wind output at the time topped 10GW, which provided high levels of low-cost electricity to the grid. However, this renewable supply may not be available during another cold spell.

National Grid’s Winter Outlook report forecasts an electricity margin this winter of 7GW, while also expecting 7GW of wind output during the peak winter. Find out more here.

 

How could this impact energy bills?

Supply margins would be placed under significantly more stress during a similar cold snap this winter, if wind output was low or non-existent. This would require another 10GW of supply being provided by gas and coal plant or imports. Such a scenario is likely to require significant price rises in the Within-day and Day-ahead markets.

Capacity Market under review

The overall objectives of this review are to assess whether:

  • the CM is needed in future;
  • the CM currently meets its objectives of ensuring security of supply, cost effectiveness, and avoiding unintended consequences;
  • these objectives remain appropriate; and
  • they can be achieved in the future in a way that imposes less regulation.

 

The call for evidence

Both the CM and EPS were introduced five years ago as part of the Energy Act 2013. The announced ‘call for evidence’ is the first step in the review process.

The Government believes both the Capacity Market and the Emissions Performance Standard are working broadly as intended. The initial document states they “do not foresee the need for fundamental change.” However, this review will allow feedback to help them understand more about stakeholder issues and whether there are any changes to be considered. With this in mind, the Government has already indicated that there are some desirable changes that could improve the CM to ensure it continues to meet its objectives in the future.

Based on stakeholder feedback, two initial priority issues have been noted for the Capacity Market review:

  1. There needs to be consideration as to whether, and how, to enable participation by subsidy-free renewables in the CM.
  2. Following the latest round of CM auctions there has been feedback in relation to interconnectors. It’s been suggested that the contribution to security of supply made by interconnectors added to the system in future will face diminishing returns, as they are reliant on the same limited pool of spare capacity in the interconnected countries. The Government will consider whether changes to the methodology are required to ensure future interconnectors are not over-compensated relative to their real contribution.

 

Ofgem review

In addition to the Government review, energy regulator Ofgem will carry out a separate review on the Capacity Market to support the process. Ofgem will be announcing the details concerning the content and arrangements of their review at a later date. However, it can be assumed that it will seek to address very similar themes.

 

The Emissions Performance Standard

The objective of the EPS is to ensure that new fossil-fuel-fired electricity generation helps improve security of supply but still contributes to the UK’s decarbonisation objectives. The mechanism is a limit on the carbon dioxide emissions produced by new fossil-fuel generation plants. The Government is seeking stakeholder views on the effectiveness of the EPS. The five-year review of the EPS will answer similar high-level questions to the CM Review.

 

What to look out for

The call for evidence will be open between 8 August and 1 October 2018. A summary of the responses will be published later this year. The outcomes of these reviews will then be reported to Parliament in summer 2019.

 

Impact on consumers

The Capacity Market’s annual auctions define both how much capacity has been bought and at what price. The overall costs for both the capacity bought and the administration of the scheme are passed on to consumer bills, with the cost of capacity being the largest element.

EIC supports security of supply and any move to maintain a fairly structured scheme that keeps price impact to customers at a minimum.

Is wind technology facing an uncertain future?

With a remaining budget of £557m (in 2012/13 prices) Utilitywise estimates that funding may not be able to cover all of the offshore wind projects currently in development, let alone provide support for any other technologies.

The next CfD auction is expected to focus heavily on offshore wind projects, with the Government eager to develop the country’s geographical advantage towards this technology. Offshore wind also faces less local opposition and environmental challenges than onshore wind. Onshore wind has been banned from entering the CfD auctions, although the next round will have an exception for projects within the Scottish Islands. This is due to the Government’s focus on what it defines as ‘less established’ technologies, and the application of onshore wind in this location fits their definition.

Growth in offshore wind across the UK is already set to accelerate from the current 6GW of capacity in operation. Just over 18GW of additional capacity is in various states of development, with 8GW of that already contracted with a CfD or FIDER subsidy agreement. A further 1.5GW is under construction (meaning the project has broken ground, so is likely to have secured funding arrangements).

All this leaves more than 8GW of offshore wind capacity up for grabs in the upcoming Capacity Market auction. However, if the clearing price in next year’s auction is similar to that in the previous auction – around £57/MWh – EIC calculations show the cost of subsidising all of this capacity would exceed the £557m budget within the next decade, when the new schemes come online.

 

What if the Strike Price falls?

Should the offshore wind Strike Price fall to £55/MWh, which some reports indicate the technology could still operate at, then the budget could support around 80% of the planned capacity by 2030.

However, if costs fell even further, and the Strike Price can be set at levels equivalent to current wholesale prices of £50/MWh at the time of agreements, then this could support all of the in development offshore projects and 40% of the planned onshore sites. In this case, projects would effectively be zero-cost with inflation the main factor providing uplift.

Currently, there is 8GW of onshore wind capacity in differing states of development, only 0.7GW of which has already secured a CfD contract (this was in earlier auctions when the technology was still allowed to take part). Around 6.5GW of the remaining capacity has yet to begin construction and would likely be seeking a subsidy contract of some kind.

 

How will this impact you?

Based on the funds currently provided to the new auctions, regardless of the Strike Price, consumers are expected to face an increase on their electricity bills of around £2.50 to £3/MWh per year by 2030.

The cost to consumers could rise further if the Government wanted to support onshore wind while still pushing for the bulk of planned offshore to be developed, and if Strike Prices were higher than those noted above. This would need a larger budget for CfD contracts and would lead to additional costs, which would then require even higher bills to ensure customers pay for the increased green energy capacity.
