Surety Bonds Reach the Power Sector: What the Ministry of Power's April 2026 Move Means for Bid and Performance Security

On 6 April 2026 the Ministry of Power issued an office memorandum introducing Insurance Surety Bonds (ISBs) as an accepted alternative to bank guarantees and bid security across all power procurement frameworks. The provision now sits inside the standard bidding guidelines for solar, wind, hybrid renewable, pumped storage and transmission projects, and the ministry has explicitly extended it to newer segments such as Battery Energy Storage Systems. States, union territories and procurement agencies have been advised to update their model documents for long-term, medium-term and short-term power purchase agreements.

This matters because power is the second large public-procurement sector, after highways, to formally let a surety bond stand where a bank guarantee used to. The legal spine is the same one NHAI relied on: the Ministry of Finance amendment to the General Financial Rules, 2017, which revised Rules 170(i) and 171(i) to widen the list of acceptable instruments for bid and performance security. Once GFR put e-bank-guarantees and surety bonds at par with conventional BGs for government procurement, each sectoral ministry had to issue its own enabling circular before tenders actually carried the option. Power has now done that.

For a broker, the read is straightforward. Every solar developer, transmission EPC firm, pumped-storage sponsor and BESS integrator bidding into a central or state tender from the second half of 2026 can, in principle, post a surety bond instead of locking collateral with a bank. The demand will not be uniform, large balance-sheet players move first, but the addressable base just expanded from roads to one of the most capital-hungry sectors in the country. The firms that win these mandates will be the ones who can explain, in plain terms, how a surety bond behaves differently from the guarantee it replaces.

Renewable and transmission contracting is a margin-thin, cash-intensive business. A developer or EPC firm typically carries bid-bond obligations on several live tenders at once, then a performance guarantee for the build period, then warranty and operations-stage guarantees that can run years past commissioning. Under the bank-guarantee route, each of those instruments consumes the firm's fund-based and non-fund-based limits, and banks usually demand margin money or fixed-deposit collateral, often a meaningful slice of the guarantee value. The practical effect is that a large chunk of a contractor's liquidity sits frozen as security rather than funding the next project.

A surety bond changes the mechanics. The insurer is the surety, and the instrument is priced on a premium rather than backed by pledged collateral. The contractor pays a premium broadly in the range of one to three per cent of the bond value annually depending on credit quality and project risk, and keeps its banking limits free for actual drawdowns on equipment, land and grid-connection costs. For a renewable developer running a multi-gigawatt pipeline, shifting even a portion of guarantee obligations to surety can release working capital that was earning nothing while parked as margin.

The broker's pitch to a power client should therefore be quantitative, not abstract. Map the client's current guarantee book, estimate the collateral and margin tied up against it, and model what migrating eligible bonds to surety frees up. That number, the cash unlocked, is what gets a CFO's attention, and it is the lever that turns a one-off bid bond into a relationship.

Brokers must be precise here, because the two instruments look similar to a procurer but behave very differently for the contractor. A bank guarantee is, in most Indian tender wordings, unconditional and payable on demand. The beneficiary invokes it, and the bank pays, full stop, with the contractor left to argue afterwards. The bank then debits the contractor's account or enforces the collateral. There is little room for the guarantor to question whether the default was genuine.

An insurance surety bond under the IRDAI (Surety Insurance Contracts) Guidelines, 2022 is closer to a tripartite suretyship. The insurer guarantees performance of the contractor's obligation to the beneficiary (the principal), but the bond is a contract of guarantee, not an on-demand instrument by default. Whether the surety can examine the validity of a claim, or must pay on first demand, depends entirely on the bond wording the procurer specifies. This is where the broker earns the fee.

Three differences deserve close attention:

• Recourse and recovery. Both a bank and a surety have recourse against the contractor after paying out. The difference is timing and security. A bank often holds collateral up front; a surety relies on a counter-indemnity and on subrogation rights against the principal, sometimes supported by promoter guarantees rather than cash margin.
• Conditionality. Procuring agencies want on-demand certainty; sureties want the right to verify default. The power-sector model documents will set this balance, and the broker should read the exact clause before promising a client an easier ride.
• Renewal and step-down. Performance bonds in power projects often reduce as milestones are met. Confirm the bond text allows the reduction and that the procurer will release proportionately, otherwise the cash-flow benefit erodes.

Highways went first, and the numbers are now public enough to set expectations. By July 2025, twelve insurance companies had issued roughly 1,600 surety bonds as bid security and 207 as performance security for NHAI contracts, valued at around Rs 10,369 crore, with total industry issuance across sectors reported in the region of Rs 60,000 crore. The headline crossing of the Rs 10,000 crore mark for NHAI alone took roughly three years from the first guidelines, which tells you two things.

First, bid bonds scale faster than performance bonds. The ratio of 1,600 bid bonds to 207 performance bonds is not an accident. Bid security is small in value, short in tenure and low in risk, the bond dies the moment the tender is awarded or lost, so insurers underwrite it readily and contractors adopt it quickly. Performance security is larger, longer and carries real default exposure, so both sides move cautiously. Expect the same pattern in power: brokers will close surety bid bonds for renewable tenders well before procurers and insurers get comfortable with multi-year performance surety on a 500 MW solar build.

Second, capacity follows confidence, not the other way round. Indian insurers were initially constrained, partly by the original 30 per cent per-contract exposure cap in the 2022 guidelines, which IRDAI later removed, and partly by thin reinsurance support for an unfamiliar class. As loss experience on highways stayed benign, appetite widened.

One practical caution belongs in every client conversation: use the highways track record as social proof, but do not promise that power-sector pricing will match road pricing. Power-project default patterns, especially grid-connection delays and curtailment-linked stress, are not the same as those of a road EPC contract, and underwriters will price the difference.

When a broker takes a power client to a surety underwriter, the file is assessed much like a credit submission, because that is what it is. The insurer is underwriting the probability that the contractor fails to perform, and the severity if it does. For a power project, several factors carry extra weight beyond a generic infrastructure surety.

The underwriter will look hard at the contractor's order book concentration and its track record of commissioning on time, because performance bonds in renewables are frequently invoked over commissioning delays rather than outright abandonment. Grid-connection dependency is a recurring theme: a developer can build a solar park to schedule and still trip its performance milestone because the transmission interconnection slipped, a risk the contractor does not fully control. Sureties read the PPA and the connectivity agreement to understand who carries that timing risk.

Key items in a typical power-surety underwriting file include:

1. Audited financials, usually three years, with a focus on net worth, gearing and the contingent-liability note that already lists outstanding bank guarantees.
2. The contract and tender documents, so the surety can size the bond and read the invocation wording.
3. A counter-indemnity from the contractor and often the promoters, the surety's primary recovery route.
4. Project-specific risk notes: technology maturity (mature solar PV versus a first-of-kind pumped-storage scheme), land and connectivity status, and offtaker credit quality.
5. The contractor's existing engineering and liability cover, because a surety prefers a client whose erection all risks and third-party exposures are already insured.

Brokers who pre-package this file, rather than handing the underwriter a bare bond request, get better terms and faster turnaround. A surety underwriter who has to chase basic credit information will either decline or load the premium.

The bond wording is where a power-sector surety placement is won or lost, and it is the part most contractors do not read until a claim hits. The procurer drafts the model bond inside the tender; the broker's job is to reconcile what the procurer demands with what the surety will actually sign.

The central tension is conditionality. State discoms and central procurers, conditioned by decades of on-demand bank guarantees, often draft surety bond formats that are effectively unconditional, payable on the beneficiary's written invocation without proof of default. A surety insurer, by contrast, wants a conditional bond where it can verify that the contractor genuinely defaulted before paying. If the broker does not flag this early, the contractor wins a tender on the assumption it can post surety, then discovers no insurer will accept the procurer's on-demand wording, and scrambles back to a bank guarantee at the eleventh hour.

Watch these wording points specifically:

• Invocation trigger. Is payment on first written demand, or on proof of contractor default with notice and a cure period? This single distinction drives both pricing and insurer appetite.
• Quantum and step-down. Does the bond value reduce as milestones are certified, and is the reduction automatic or does it need procurer sign-off?
• Validity and extension. Power performance bonds can run through warranty and operations stages. Confirm the surety's willingness to extend or renew, and the premium mechanics on extension.
• Governing law and dispute forum. Surety claims that go contested end up in arbitration or court; the policy wording should match the underlying contract's dispute clause.

A practical broker move: get the surety underwriter to pre-clear the procurer's model bond format before the client bids, so the contractor knows at bid stage whether surety is genuinely available for that tender or whether a bank guarantee remains the only route.

The moment that separates a good surety placement from a bad one is the claim, and brokers should walk power clients through it before they sign, not after a discom invokes. When a beneficiary calls on a surety bond, the insurer pays the principal (subject to the bond's conditionality) and then exercises subrogation and counter-indemnity rights to recover from the contractor. This is the point most contractors miss: a surety bond is not insurance that absorbs the contractor's loss. It is a guarantee, and after the insurer pays the procurer, it comes after the contractor for the full amount, plus costs.

In practice the recovery chain runs through the indemnity the contractor signed at inception. If promoters gave personal guarantees, those are triggered too. So a contractor who treats a surety bond as a soft alternative to a bank guarantee, assuming a default just means a premium loss, is badly mistaken; the financial consequence of a genuine default is broadly the same as a bank enforcing its margin, just sequenced differently.

Where surety can be friendlier is in disputed invocations. Because a properly drafted conditional bond lets the surety examine the claim, a contractor facing a wrongful or premature invocation by a state procurer has, in theory, an ally with an interest in resisting an unjustified call, something a bank issuing an on-demand guarantee never provides. That advantage evaporates if the procurer forced an on-demand wording.

The broker who frames all of this honestly, the cash benefit, the conditionality battle and the recovery reality, builds a relationship that survives the first hard claim. The one who oversells surety as free money does not.

This is a relationship-acquisition window, and it will not stay open long. Once surety becomes standard in power tenders, the contractors who needed help structuring it will already have an adviser. Here is the concrete sequence for a broker working the power book through the second half of 2026.

Start with a guarantee audit for each power client. List every outstanding bank guarantee, bid, performance, advance-payment and retention, with value, tenure, beneficiary and the collateral or margin tied against it. The total margin locked is your headline number. Then segment which of those obligations can migrate to surety: bid bonds first, performance bonds where the procurer's wording is workable, and leave advance-payment guarantees for later since insurers are warier of those.

Build a panel relationship before you need it. Identify which of the dozen-odd Indian insurers active in surety have genuine power-sector appetite and reinsurance support, and pre-agree indicative terms and the underwriting checklist. A broker who can name the surety market and quote an indicative rate in the first client meeting looks like an expert; one who says "let me find out" looks like an order-taker.

Finally, integrate surety into the wider power-risk conversation. A developer buying surety is the same developer who needs engineering insurance for the build and liability cover for third-party exposures, and who lives with grid and curtailment risk every day. Position surety as one instrument inside a coordinated programme, not a standalone product, and the placement becomes the entry point to the whole account. The Ministry of Power has handed brokers a reason to call every IPP and EPC firm in the country. Use it before the competition does.
