For many organisations, renewable electricity has become one of the most visible components of a corporate decarbonisation strategy.
A company may install rooftop solar, procure renewable electricity through open access arrangements, enter into a power purchase agreement or purchase renewable energy certificates. These initiatives can contribute to renewable energy targets and may support the organisation’s broader climate strategy.
However, as renewable power procurement becomes more sophisticated, the decision is no longer only an ESG decision.
It can also be a procurement decision, a long-term commercial commitment, a financial reporting consideration and a data governance issue.
This is becoming particularly relevant in India following the Ministry of Corporate Affairs’ notification of the Companies (Indian Accounting Standards) Amendment Rules, 2026. Among other amendments, the rules introduce changes relating to contracts referencing nature-dependent electricity under Ind AS 109 and Ind AS 107. The amendments apply to annual reporting periods beginning on or after 1 April 2026.
The development is relevant because renewable electricity contracts can have characteristics that make them more complex than conventional electricity purchases. Generation from solar and wind depends on natural conditions, while contractual arrangements can involve committed volumes, variable generation, market settlement mechanisms and long-term pricing structures.
For companies, this means renewable power procurement needs to be evaluated from multiple perspectives before the contract is entered into.
The question is no longer simply:
“How much renewable electricity can we procure?”
It is increasingly:
“How will the arrangement work operationally, commercially, financially and from an ESG reporting perspective?”
Renewable Energy Has Moved from Ambition to Procurement
Corporate renewable energy strategies have evolved considerably.
Initially, organisations often approached renewable energy through relatively straightforward initiatives such as installing rooftop solar or purchasing renewable energy certificates.
As corporate climate commitments have become more structured, companies are increasingly exploring longer-term procurement arrangements.
These may include physical power purchase agreements, captive or group captive arrangements, open access procurement and other contractual structures.
The attraction is understandable.
A long-term renewable electricity arrangement can potentially provide greater visibility over renewable energy supply, support decarbonisation objectives and form part of a company’s broader energy strategy.
But a long-term contract also creates obligations.
The organisation needs to understand how much electricity it is committing to purchase, what happens when renewable generation varies, how the price is determined, what happens to excess electricity and what financial risks arise from the arrangement.
These questions are not separate from ESG.
They determine whether the renewable energy strategy can actually deliver the intended outcome.
Why Renewable Electricity Is Different from Conventional Power
One of the characteristics that makes renewable power procurement distinctive is the variability of generation.
A solar project does not generate the same amount of electricity every hour of every day.
Generation changes with sunlight, weather conditions, seasonality and other natural factors.
Wind generation similarly depends on wind conditions.
The buyer may therefore enter into an arrangement where the amount of electricity actually generated varies over time.
This creates a fundamental difference between the company’s planned renewable electricity consumption and the electricity physically available from the renewable generating asset.
The International Accounting Standards Board’s amendments relating to nature-dependent electricity contracts specifically address contracts where the buyer is exposed to variability in the underlying amount of electricity because generation depends on uncontrollable natural conditions such as weather.
For companies, understanding this variability is important before entering into the contract.
A renewable energy target may be expressed as a percentage of annual electricity consumption.
The contractual arrangement, however, may operate at an hourly or more granular level.
These are not necessarily the same thing.
The Difference Between an ESG Target and an Energy Contract
An organisation may have a target such as:
“Procure 50% of electricity from renewable sources.”
This is an ESG objective.
But achieving the objective requires a commercial mechanism.
The company needs to determine:
Where will the renewable electricity come from?
What type of arrangement will be used?
How much electricity will be contracted?
For how long?
What happens if generation is lower than expected?
What happens if the company consumes less electricity than anticipated?
Who bears the risk of excess generation?
How will the electricity be priced?
What environmental attributes are associated with the electricity?
These questions determine the practical outcome of the ESG commitment.
A target therefore cannot be separated from the contract used to achieve it.
This is why sustainability teams should be involved before renewable energy agreements are finalised rather than only after procurement has completed the transaction.
Renewable PPAs Can Create Accounting Questions
One of the most important developments in this area is the increasing attention being given to the accounting treatment of renewable power purchase agreements.
The 2026 Ind AS amendments address contracts referencing nature-dependent electricity and include amendments to Ind AS 109 and Ind AS 107. The changes are intended to address specific challenges associated with such contracts, including the application of the own-use exemption, hedge accounting and additional disclosures.
This matters because a renewable PPA may not always be treated in the same way as a straightforward electricity purchase.
The accounting assessment depends on the contractual terms and the nature of the arrangement.
Companies therefore need to involve finance and accounting teams when renewable power contracts are being structured.
The sustainability objective alone does not determine the accounting treatment.
The actual contractual features matter.
What Is the Own-Use Question?
One important concept in the accounting assessment of electricity contracts is whether the organisation is entering into the arrangement primarily to meet its own electricity requirements.
The accounting amendments provide additional guidance around the own-use exemption for contracts referencing nature-dependent electricity.
At a high level, the issue is whether the contract is genuinely connected to the company’s expected electricity consumption or whether its structure effectively creates exposure to electricity price movements or other financial characteristics.
The detailed assessment can involve factors such as expected consumption, contracted volumes, generation variability and what the company does with electricity that it does not consume.
This is why the accounting analysis should not be performed after the contract has already been signed.
The contract structure itself can influence the accounting assessment.
Physical PPAs and Virtual PPAs Are Not the Same
Another important distinction is between physical and virtual arrangements.
In a physical PPA, electricity is physically delivered under the arrangement, subject to the structure of the applicable power market and contract.
A virtual PPA generally operates differently. It can function as a contract for difference where the parties settle the difference between an agreed price and a market price rather than physically delivering electricity to the buyer.
The accounting implications can therefore differ substantially.
The amendments relating to nature-dependent electricity specifically distinguish arrangements where electricity is physically delivered from contracts that are effectively financial settlements. For example, a virtual PPA does not involve physical transfer of electricity and therefore does not qualify for the own-use exemption simply because it is connected with renewable electricity.
This distinction is important for sustainability teams because two arrangements can both be described commercially as “renewable energy procurement” while having very different contractual and accounting characteristics.
The Sustainability Team Needs to Understand the Contract
Traditionally, renewable energy procurement may have been led primarily by procurement, energy or finance teams.
That approach becomes less effective when the organisation has committed to a specific renewable energy target.
The sustainability team needs to understand what the contract actually delivers.
For example, if a company signs a renewable power agreement for a specified volume of electricity, the sustainability team needs to understand whether that volume is expected to correspond with actual consumption.
It also needs to understand how renewable electricity attributes are treated and what information will be available for sustainability reporting.
This is particularly important where the organisation intends to use the arrangement to support its emissions calculations.
The contract should therefore be assessed against the company’s ESG reporting methodology before the agreement is finalised.
Renewable Energy Claims Depend on Data
A company cannot substantiate its renewable electricity performance simply because it has signed a renewable energy contract.
It needs appropriate data and documentation.
Depending on the arrangement, relevant information may include:
- Contracted renewable electricity volume
- Actual electricity delivered
- Electricity consumed
- Electricity generated
- Metering information
- Applicable billing records
- Renewable energy certificates or other environmental attributes
- Grid electricity consumption
- Contractual settlement information
- Details of the generating facility
- Relevant allocation methodology
The precise information required depends on the arrangement and reporting framework.
The underlying principle is consistent: the sustainability claim should be connected to evidence.
This is particularly important because renewable electricity can affect reported Scope 2 emissions.
If the organisation reports market-based Scope 2 emissions, the relevant contractual instruments and environmental attributes need to meet the requirements of the applicable reporting methodology.
Therefore, renewable procurement and emissions reporting cannot be treated as two independent processes.
Renewable Energy Data Should Connect Finance, Energy and ESG
One of the practical challenges is that the relevant information often sits in different departments.
The energy team may know how much electricity was generated.
The procurement team may hold the contract.
Finance may hold invoices and payment records.
The sustainability team may calculate Scope 2 emissions.
The plant may hold meter readings.
Without coordination, the company may end up with multiple versions of what should be the same underlying information.
For example, the renewable electricity volume recorded in the ESG team’s spreadsheet may not exactly match the amount reflected in the finance records.
This does not necessarily indicate an error.
There may be legitimate differences in timing, measurement or contractual treatment.
But the organisation should understand those differences.
A strong renewable energy data process should therefore create a clear link between:
Contract → Metering → Electricity consumption → Financial records → Environmental attributes → ESG reporting
This creates a much stronger foundation for both financial reporting and sustainability disclosures.
Forecasting Renewable Generation Becomes Important
Because renewable generation depends on natural conditions, companies need to consider variability when planning their energy requirements.
A contract may be based on expected generation.
Actual generation can differ.
The company may therefore need to supplement renewable electricity with grid electricity or other sources.
This has implications for both energy planning and ESG reporting.
A company may have a renewable procurement target based on annual electricity consumption but experience significant variation during individual periods.
This means the organisation should not rely only on an annual percentage target.
It may also need to understand how renewable generation aligns with its actual consumption profile.
This is particularly relevant for businesses with energy-intensive manufacturing facilities operating continuously.
The sustainability team should therefore work with energy and operations teams to understand the company’s electricity demand profile.
Renewable Energy Procurement Is Also a Financial Decision
A renewable PPA is generally a long-term commitment.
The organisation should therefore evaluate more than the environmental benefits.
Important considerations can include:
Price risk: How does the contract price compare with expected market electricity prices?
Volume risk: What happens if the company consumes less electricity than anticipated?
Generation risk: What happens if the renewable project produces less electricity than expected?
Settlement risk: How are differences between contracted and actual electricity handled?
Counterparty risk: What happens if the project developer cannot meet its contractual obligations?
Regulatory risk: Could changes in power market rules affect the arrangement?
Accounting risk: Could the contractual structure create financial reporting consequences?
ESG reporting risk: Will the organisation have sufficient information to substantiate its renewable energy and emissions claims?
A contract that looks attractive from an ESG perspective may still require careful evaluation from these other perspectives.
The Role of Environmental Attributes Needs Attention
Renewable electricity procurement can involve environmental attributes associated with the electricity.
These attributes can be important for sustainability reporting.
The company therefore needs to understand exactly what it is purchasing and what rights it receives under the agreement.
For example, the contract should clearly establish how renewable energy certificates or other relevant environmental attributes are treated.
The company should also understand whether those attributes are retained by the buyer, transferred to another party or otherwise allocated.
This matters because the organisation should not make an environmental claim based on an attribute that it does not actually hold or have the right to use.
The contract, therefore, becomes part of the evidence supporting the ESG disclosure.
Renewable PPAs and the Risk of Overclaiming
As renewable energy procurement becomes more widespread, the quality of sustainability claims becomes increasingly important.
A company may state that it has “shifted to renewable energy” even though the underlying arrangement covers only part of its electricity consumption.
Another company may describe its entire electricity consumption as renewable when the contractual arrangement relates to a specific facility or volume.
Such statements can create confusion if the underlying information is not clearly defined.
The solution is not necessarily to avoid renewable energy claims.
It is to make them precise.
A company should be able to explain:
What proportion of electricity is covered?
Which facilities are included?
What period does the claim relate to?
What type of renewable arrangement is being used?
What evidence supports the claim?
How has the renewable electricity been treated in emissions calculations?
This level of clarity strengthens the credibility of sustainability reporting.
The New Ind AS Requirements Increase the Importance of Disclosure
The 2026 amendments do not only address recognition and measurement questions.
They also introduce additional disclosure requirements for certain contracts referencing nature-dependent electricity. These disclosures are intended to provide users of financial statements with information about the financial effects and risks associated with such contracts.
This is important because renewable energy arrangements can involve future contractual commitments.
For example, a long-term electricity contract may create future cash flow commitments that extend over several years.
Financial statement users may therefore need information that helps them understand the nature and potential financial effect of these arrangements.
This reinforces a broader trend in corporate reporting.
Sustainability-related contracts are increasingly becoming relevant to investors not only because they demonstrate environmental ambition but also because they can create financial commitments and exposures.
Accounting Should Not Be an Afterthought
One of the most practical lessons for organisations is the importance of involving finance early.
A renewable energy agreement should not first be sent to the accounting team after commercial negotiations have concluded.
Finance should be involved while the contract is being designed and reviewed.
This allows the organisation to understand potential accounting implications before contractual terms become difficult to change.
The same principle applies to sustainability reporting.
The ESG team should review the arrangement before signing to determine whether the contract can support the intended environmental claim and reporting treatment.
A cross-functional review could therefore involve:
Sustainability → Energy → Procurement → Finance → Legal → Risk
Each function examines a different dimension of the same transaction.
This is much more effective than evaluating the contract separately from each functional perspective.
Renewable Energy and Corporate Decarbonisation
Renewable electricity remains an important tool for companies seeking to reduce their electricity-related emissions.
But procurement alone does not constitute a complete decarbonisation strategy.
A company may also need to address energy efficiency, process optimisation, fuel switching, electrification, technology upgrades and other relevant emission sources.
Renewable electricity should therefore be considered as one component of the broader decarbonisation roadmap.
The organisation should understand how much of its emissions can realistically be influenced through renewable electricity procurement and where other interventions are necessary.
This becomes particularly important for manufacturing businesses where a significant portion of emissions may arise from direct fuel use or industrial processes rather than purchased electricity.
The renewable energy strategy should therefore be connected to the company’s overall emissions profile.
What Companies Should Review Before Entering a Renewable Energy Contract
Companies considering renewable electricity procurement should conduct a structured review before signing the agreement.
First, they should establish the actual electricity demand profile of the relevant facilities.
Second, they should determine the renewable energy objective and how it fits into the company’s climate strategy.
Third, they should evaluate the contractual structure, including volume, duration, pricing, delivery and settlement terms.
Fourth, finance should assess the potential accounting treatment under the applicable Ind AS requirements.
Fifth, the sustainability team should assess how the arrangement will support ESG reporting and emissions calculations.
Sixth, the organisation should determine what evidence will be available throughout the contract period.
Finally, the company should establish responsibility for monitoring performance after the agreement is signed.
This last point is particularly important.
A contract signed today may continue for many years.
The organisation therefore needs a process for monitoring whether the arrangement continues to deliver what was originally intended.
Renewable Energy Procurement Needs Better Governance
As renewable power arrangements become more complex, governance becomes increasingly important.
A company should know who is responsible for the contract.
It should know who monitors electricity generation and consumption.
It should know who calculates the environmental impact.
It should know who reviews accounting treatment.
It should know who approves external sustainability claims.
These responsibilities should not remain implicit.
A defined governance structure can reduce the risk of conflicting information and help ensure that commercial, accounting and ESG requirements are considered together.
This is particularly relevant for companies with multiple facilities or multiple renewable energy arrangements.
Without central coordination, individual plants may enter into arrangements with different contractual structures and reporting implications.
From Renewable Procurement to Renewable Energy Management
The next stage of corporate renewable energy adoption is therefore not simply about procuring more renewable electricity.
It is about managing renewable energy as a strategic resource.
Companies need to understand how much renewable electricity they require, how much they actually receive, how generation varies, how contracts affect cash flows, how environmental attributes are treated and how all of this information flows into ESG reporting.
The organisation should be able to connect the commercial contract with the environmental outcome.
That requires better data.
It also requires stronger collaboration between functions.
And increasingly, it requires finance to be part of the sustainability conversation from the beginning.
The Bigger ESG Implication
The evolution of renewable energy procurement reflects a broader transformation in ESG management.
Sustainability initiatives are becoming embedded in contracts, financial arrangements and operational decisions.
The 2026 Ind AS amendments provide a specific example of this shift. By addressing accounting questions associated with nature-dependent electricity contracts, the framework recognises that renewable electricity arrangements can create financial reporting considerations alongside their environmental objectives.
For businesses, this means renewable energy should not be treated as a standalone sustainability project.
It is a business decision with environmental, operational, commercial and financial dimensions.
The companies that manage these dimensions together can build stronger renewable energy strategies and more reliable sustainability reporting.
The future of renewable energy procurement will therefore depend not only on how much clean electricity companies buy.
It will also depend on how well they understand the contracts, data and financial implications behind that electricity.
How ESG360 Supports Organisations
ESG360 supports organisations in developing structured ESG strategies, carbon footprint assessments, sustainability reporting, ESG data systems and climate-related initiatives.
For companies implementing renewable energy strategies, the focus should extend beyond identifying a renewable energy source. Organisations need to understand how the arrangement connects with their energy consumption, emissions calculations, ESG disclosures, documentation and broader decarbonisation objectives.
A structured approach can help organisations establish clear ownership of renewable energy data, connect contractual information with sustainability reporting and strengthen the evidence supporting environmental claims.
As renewable energy becomes increasingly integrated into corporate operations and financial arrangements, the boundaries between sustainability, procurement, finance and reporting will continue to become less distinct.
Renewable power is no longer just an ESG decision.
It is a business decision that needs to work across all of them.
