STRATEGIC REPORT
FOR THE YEAR ENDED 31 MARCH 2025
- 1 -

The directors present the strategic report for the year ended 31 March 2025.

Principal activities

Welsh Power Group Limited is part of a Group that provides development and asset management services for flexible generation, storage, and grid stability assets.

 

The company’s principal source of revenue is its Management Services Agreements (MSAs). MSAs are signed with owners of energy generation and infrastructure assets who outsource the operations of the assets to the company. Welsh Power’s current portfolio of managed assets includes both operational assets and assets under construction. The company also originates projects in the energy sector, supporting its long-term growth objectives.

 

The assets under management play a key role in the UK’s energy transition, providing flexible and dispatchable power generation to complement the growth of renewable forms of generation. The company also manages stability assets which ensure the electricity system has adequate resilience to operate predominantly on low carbon forms of electricity generation.

 

At 31 March 2025, the company has 47 projects (2024: 40) under management.

Business Review

The company’s revenue for the year was £7,811,000, an increase compared to the previous year of £6,578,000, primarily driven by customer acquisition, and expanded scope for existing customers. Certain MSAs include performance-based components that are linked to the operational success and asset availability, which supported revenue resilience during the period.

Profit for the financial year was £4,203,000, an increase compared to the previous year profit of £3,301,000.

The Directors remain confident in the robustness of the company’s business model. Profitability is underpinned by the long-term nature of the company’s contractual arrangements, which provide a stable foundation to the core business.

Looking ahead, the company remains focused on expanding its portfolio and maintaining operational excellence. The long-term nature of the contracts and the diversified customer base provide a solid foundation for future growth.

Principal risks and uncertainties

 

Financial and liquidity risk

The company faces financial risk that could impact its performance, including the loss of key customers, unexpected costs and unforeseen events. The company manages these risks by maintaining strong cash reserves and closely monitoring cash flow. Additionally, the company has developed specific strategies to address its principal risks, as outlined below.

 

Operational and construction delays

Delays in the construction of new assets could impact the company’s project timelines and financial performance. The company mitigates this risk by employing robust project management practices, maintaining strong relationships with contractors and suppliers, and building flexibility into project schedules.

 

Regulatory and policy changes

Changes in energy regulations or government policies, particularly those relating to the energy transition and grid stability, could impact the company’s operations. The company actively monitors regulatory developments and adapts its business strategy to align with policy shifts, particularly those supporting the transition to a net-zero economy.

STRATEGIC REPORT (CONTINUED)
FOR THE YEAR ENDED 31 MARCH 2025
- 2 -

Customer retention and concentration risk

As with all customer focused businesses the loss of customers is a key risk particularly so given the company’s relatively small number of primary customers. The company actively works to mitigate this risk by focusing on strengthening its relationships with customers and ensuring high standards of service and performance.

 

Additionally, the long-term nature of the contracts the company holds means that any impact from customer loss is likely to be gradual, providing time to implement effective mitigation strategies, such as cost reduction and pursuing new customers. However, the loss of key customers could still affect the company's future financial performance, making customer retention and acquisition a key continued focus for the business.

 

Credit risk

The company is exposed to credit risk from customers operating in a volatile market environment. Market fluctuations, such as changes in energy prices or shifts in regulatory frameworks, can affect the financial stability of its customers. The company actively manages this risk through initial credit assessments and monitoring the financial health throughout the duration of their contracts. Additionally, the diversification of customer base works to reduce the potential impact of any single customer’s financial instability on the company.

Financial and non-financial key performance indicators

The financial and non-financial key performance indicators of the company are as follows:

DIRECTORS' RESPONSIBILITIES STATEMENT
FOR THE YEAR ENDED 31 MARCH 2025
- 4 -

The directors are responsible for preparing the annual report and the financial statements in accordance with applicable law and regulations.

Company law requires the directors to prepare financial statements for each financial year. Under that law the directors have elected to prepare the financial statements in accordance with United Kingdom Generally Accepted Accounting Practice (United Kingdom Accounting Standards and applicable law). Under company law, the directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs of the company and of the profit or loss of the company for that period.

In preparing these financial statements, the directors are required to:

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the company’s transactions and disclose with reasonable accuracy at any time the financial position of the company and enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

WELSH POWER GROUP LIMITED
INDEPENDENT AUDITOR'S REPORT
TO THE MEMBER OF WELSH POWER GROUP LIMITED
- 5 -
Opinion

We have audited the financial statements of Welsh Power Group Limited (the 'company') for the year ended 31 March 2025 which comprise the profit and loss account, the statement of comprehensive income, the balance sheet, the statement of changes in equity and notes to the financial statements, including significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102 The Financial Reporting Standard applicable in the UK and Republic of Ireland (United Kingdom Generally Accepted Accounting Practice).

In our opinion the financial statements:

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditor's responsibilities for the audit of the financial statements section of our report. We are independent of the company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC’s Ethical Standard, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Conclusions relating to going concern

In auditing the financial statements, we have concluded that the directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate.

 

Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.

 

Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this report.

Other information

The other information comprises the information included in the annual report other than the financial statements and our auditor's report thereon. The directors are responsible for the other information contained within the annual report. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon. Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact.

 

We have nothing to report in this regard.

Opinions on other matters prescribed by the Companies Act 2006

In our opinion, based on the work undertaken in the course of our audit:

WELSH POWER GROUP LIMITED
INDEPENDENT AUDITOR'S REPORT (CONTINUED)
TO THE MEMBER OF WELSH POWER GROUP LIMITED

Matters on which we are required to report by exception

In the light of the knowledge and understanding of the company and its environment obtained in the course of the audit, we have not identified material misstatements in the strategic report or the directors' report.

 

We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion:

Responsibilities of directors

As explained more fully in the directors' responsibilities statement, the directors are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error. In preparing the financial statements, the directors are responsible for assessing the company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the company or to cease operations, or have no realistic alternative but to do so.

Auditor's responsibilities for the audit of the financial statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor's report that includes our opinion. Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

The extent to which our procedures are capable of detecting irregularities, including fraud, is detailed below.

Our approach to identifying and assessing the risks of material misstatement in respect of irregularities, including fraud and non-compliance with laws and regulations, was as follows:

We assessed the susceptibility of the company's financial statements to material misstatement, including obtaining an understanding of how fraud might occur, by:

WELSH POWER GROUP LIMITED
INDEPENDENT AUDITOR'S REPORT (CONTINUED)
TO THE MEMBER OF WELSH POWER GROUP LIMITED
- 7 -

To address the risk of fraud through management bias and override of controls, we:

There are inherent limitations in our audit procedures described above. The more removed that laws and regulations are from financial statements, the less likely it is that we would become aware of non-compliance. Auditing standards also limit the audit procedures required to identify non-compliance with laws and regulations to enquiry of the directors and other management and the inspection of regulatory and legal correspondence, if any.

 

Material misstatements that arise due to fraud can be harder to detect than those that arise from error as they may involve deliberate concealment or collusion.

A further description of our responsibilities is available on the Financial Reporting Council’s website at: https://www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor's report.

Use of our report

This report is made solely to the company's member in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the company's member those matters we are required to state to the member in an auditor's report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company and the company's member, for our audit work, for this report, or for the opinions we have formed.

WELSH POWER GROUP LIMITED
NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 MARCH 2025
- 12 -
1
Accounting policies
Company information

Welsh Power Group Limited is a private company limited by shares incorporated in England and Wales. The registered office is Fourth Floor, 2 Kingsway, Cardiff, CF10 3FD.

1.1
Accounting convention

These financial statements have been prepared in accordance with FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of Ireland” (“FRS 102”) and the requirements of the Companies Act 2006.

The financial statements are prepared in sterling, which is the functional currency of the company. Monetary amounts in these financial statements are rounded to the nearest thousand.

The financial statements have been prepared under the historical cost convention. The principal accounting policies adopted are set out below.

This company is a qualifying entity for the purposes of FRS 102, being a member of a group where the parent of that group prepares publicly available consolidated financial statements, including this company, which are intended to give a true and fair view of the assets, liabilities, financial position and profit or loss of the group. The company has therefore taken advantage of exemptions from the following disclosure requirements:

 

 

The financial statements of the company are consolidated in the financial statements of Carron Energy Limited. These consolidated financial statements are available from its registered office, Fourth Floor, 2 Kingsway, Cardiff, United Kingdom, CF10 3FD.

The company has taken advantage of the exemption under section 400 of the Companies Act 2006 not to prepare consolidated accounts. The financial statements present information about the company as an individual entity and not about its group.

1.2
Going concern

Atruet the time of approving the financial statements, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future. Thus the directors continue to adopt the going concern basis of accounting in preparing the financial statements.

1.3
Turnover

Turnover is recognised at the fair value of the consideration received or receivable for services provided in the normal course of business, and is shown net of VAT and other sales related taxes. The fair value of consideration takes into account trade discounts, settlement discounts and volume rebates.

 

Turnover is recognised to the extent that it is probable that economic benefits will flow to the company and the revenue can be reliably measured.

Dividend income from shares in group undertakings

Dividend income from investments is recognised when the shareholders’ rights to receive payment have been established (provided that it is probable that the economic benefits will flow to the company and the amount of revenue can be measured reliably).

Accounting policies
(Continued)
- 13 -
1.4
Tangible fixed assets

Tangible fixed assets are initially measured at cost and subsequently measured at cost or valuation, net of depreciation and any impairment losses.

Depreciation is recognised so as to write off the cost or valuation of assets less their residual values over their useful lives on the following bases:

Leasehold improvements
4 years straight line
Fixtures and fittings
4 years straight line
Computers
2 - 4 years straight line

Residual value represents the estimated amount which would currently be obtained from disposal of an asset, after deducting estimated costs of disposal, if the asset were already of the age and in the condition expected at the end of its useful life.

 

The gain or loss arising on the disposal of an asset is determined as the difference between the sale proceeds and the carrying value of the asset, and is credited or charged to profit or loss.

1.5
Fixed asset investments

Interests in subsidiaries and jointly controlled entities are initially measured at cost and subsequently measured at cost less any accumulated impairment losses. The investments are assessed for impairment at each reporting date and any impairment losses or reversals of impairment losses are recognised immediately in profit or loss.

A subsidiary is an entity controlled by the company. Control is the power to govern the financial and operating policies of the entity so as to obtain benefits from its activities.

Entities in which the company has a long term interest and shares control under a contractual arrangement are classified as jointly controlled entities.

1.6
Financial instruments

The company has elected to apply the provisions of Section 11 ‘Basic Financial Instruments’ and Section 12 ‘Other Financial Instruments Issues’ of FRS 102 to all of its financial instruments.

 

Financial instruments are recognised in the company's balance sheet when the company becomes party to the contractual provisions of the instrument.

 

Financial assets and liabilities are offset, with the net amounts presented in the financial statements, when there is a legally enforceable right to set off the recognised amounts and there is an intention to settle on a net basis or to realise the asset and settle the liability simultaneously.

 

Debtors and creditors with no stated interest rate and receivable or payable within one year are recorded at transaction price. Any losses arising from impairment are recognised in the profit and loss account in other administrative expenses.

Other financial assets

Other financial assets, including investments in equity instruments which are not subsidiaries, associates or joint ventures, are initially measured at fair value, which is normally the transaction price. Such assets are subsequently carried at fair value and the changes in fair value are recognised in profit or loss, except that investments in equity instruments that are not publicly traded and whose fair values cannot be measured reliably are measured at cost less impairment.

Deferred development costs

Project development costs, including those related to site identification, land acquisition, design, and obtaining consents, are deferred when it is probable that the resulting project will generate future economic benefits for the company at least equal to the costs incurred. Costs that are not expected to be recoverable are expensed in the period in which they are incurred, or when it becomes apparent that the project will not proceed.

Impairment of financial assets

Financial assets, other than those held at fair value through profit and loss, are assessed for indicators of impairment at each reporting end date.

 

Financial assets are impaired where there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows have been affected. If an asset is impaired, the impairment loss is the difference between the carrying amount and the present value of the estimated cash flows discounted at the asset’s original effective interest rate. The impairment loss is recognised in profit or loss.

 

If there is a decrease in the impairment loss arising from an event occurring after the impairment was recognised, the impairment is reversed. The reversal is such that the current carrying amount does not exceed what the carrying amount would have been, had the impairment not previously been recognised. The impairment reversal is recognised in profit or loss.

Derecognition of financial assets

Financial assets are derecognised only when the contractual rights to the cash flows from the asset expire or are settled, or when the company transfers the financial asset and substantially all the risks and rewards of ownership to another entity, or if some significant risks and rewards of ownership are retained but control of the asset has transferred to another party that is able to sell the asset in its entirety to an unrelated third party.

Other financial liabilities

Derivatives, including interest rate swaps and forward foreign exchange contracts, are not basic financial instruments. Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value. Changes in the fair value of derivatives are recognised in profit or loss in finance costs or finance income as appropriate, unless hedge accounting is applied and the hedge is a cash flow hedge.

 

Debt instruments that do not meet the conditions in FRS 102 paragraph 11.9 are subsequently measured at fair value through profit or loss. Debt instruments may be designated as being measured at fair value through profit or loss to eliminate or reduce an accounting mismatch or if the instruments are measured and their performance evaluated on a fair value basis in accordance with a documented risk management or investment strategy.

Derecognition of financial liabilities

Financial liabilities are derecognised when the company’s contractual obligations expire or are discharged or cancelled.

1.7
Taxation

The tax expense represents the sum of the tax currently payable and deferred tax.

Current tax

The company’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the reporting end date.

- 15 -
Deferred tax

Deferred tax liabilities are generally recognised for all timing differences and deferred tax assets are recognised to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits. Such assets and liabilities are not recognised if the timing difference arises from goodwill or from the initial recognition of other assets and liabilities in a transaction that affects neither the tax profit nor the accounting profit.

 

The carrying amount of deferred tax assets is reviewed at each reporting end date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realised. Deferred tax is charged or credited in the profit and loss account, except when it relates to items charged or credited directly to equity, in which case the deferred tax is also dealt with in equity. Deferred tax assets and liabilities are offset when the company has a legally enforceable right to offset current tax assets and liabilities and the deferred tax assets and liabilities relate to taxes levied by the same tax authority.

1.8
Employee benefits

The costs of short-term employee benefits are recognised as a liability and an expense, unless those costs are required to be recognised as part of the cost of stock or fixed assets.

 

The cost of any unused holiday entitlement is recognised in the period in which the employee’s services are received.

 

Termination benefits are recognised immediately as an expense when the company is demonstrably committed to terminate the employment of an employee or to provide termination benefits.

1.9
Retirement benefits

Payments to defined contribution retirement benefit schemes are charged as an expense as they fall due.

1.10
Share-based payments

Equity-settled share-based payments are measured at fair value at the date of grant by reference to the fair value of the equity instruments granted using the Black-Scholes model. The fair value determined at the grant date is expensed on a straight-line basis over the vesting period, based on the estimate of shares that will eventually vest. A corresponding adjustment is made to equity.

When the terms and conditions of equity-settled share-based payments at the time they were granted are subsequently modified, the fair value of the share-based payment under the original terms and conditions and under the modified terms and conditions are both determined at the date of the modification. Any excess of the modified fair value over the original fair value is recognised over the remaining vesting period in addition to the grant date fair value of the original share-based payment. The share-based payment expense is not adjusted if the modified fair value is less than the original fair value.

 

Cancellations or settlements (including those resulting from employee redundancies) are treated as an acceleration of vesting and the amount that would have been recognised over the remaining vesting period is recognised immediately.

1.11
Leases

Rentals payable under operating leases, including any lease incentives received, are charged to profit or loss on a straight line basis over the term of the relevant lease except where another more systematic basis is more representative of the time pattern in which economic benefits from the leases asset are consumed.

Foreign exchange

Transactions in currencies other than pounds sterling are recorded at the rates of exchange prevailing at the dates of the transactions. At each reporting end date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at the rates prevailing on the reporting end date. Gains and losses arising on translation in the period are included in profit or loss.

2
Judgements and key sources of estimation uncertainty

In the application of the company’s accounting policies, the directors are required to make judgements, estimates and assumptions about the carrying amount of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

 

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised where the revision affects only that period, or in the period of the revision and future periods where the revision affects both current and future periods.

Critical judgements

The following judgements (apart from those involving estimates) have had the most significant effect on amounts recognised in the financial statements.

Deferred development costs

At 31 March 2025 the company had deferred development costs of £21,000 (2024: £24,000) relating to site identification, land acquisition, design, and consents on projects. Costs are deferred where it is probable that future economic benefits will flow to the company at least equivalent to the costs incurred. Management applies judgement in determining whether development costs meet the criteria for deferral. Costs are capitalised only when it is probable that future economic benefits will exceed the costs incurred. This involves assessing project viability, expected returns, and recoverability. Deferred costs are reviewed regularly and written off if the project is no longer expected to proceed.

Turnover

All turnover relates to the company's principal activities as laid out in the Directors' report.

 

All turnover arose in the UK.
