Delay in Start-Up (DSU) Insurance

Quick Summary

• Delay in Start-Up (DSU) Insurance protects against financial losses arising from delayed project commissioning.
• It responds only when the delay results from insured physical damage during construction or installation.
• The cover is widely used for power, infrastructure, renewable energy, manufacturing, and industrial projects.
• DSU Insurance is also commonly referred to as Advance Loss of Profits (ALOP) Insurance.
• Good project documentation and delay analysis play an important role during claims.

What is Delay in Start-Up (DSU) Insurance?

Delay in Start-Up Insurance is a specialised engineering insurance cover that protects project owners against financial losses when an insured physical damage event delays the commencement of commercial operations.

Unlike property insurance, which focuses on repairing or replacing damaged assets, DSU Insurance addresses the economic impact of the delay. The policy is generally considered for projects where revenue generation depends on timely completion and successful commissioning.

The objective is simple: to reduce the financial burden created when an unforeseen insured event postpones the project's ability to generate income.

Why Construction Delays Can Become a Financial Problem

Construction delays are often viewed as an operational issue. However, for large capital-intensive projects, they quickly become a financial concern.

A project that is delayed by just a few months may experience:

• Loss of expected revenue
• Continued loan interest and financing costs
• Higher project overheads
• Delayed return on investment
• Missed contractual milestones
• Pressure from investors and lenders

For many infrastructure projects, these financial losses can exceed the actual cost of repairing damaged property.

Consider a wind farm scheduled to begin supplying electricity before the peak wind season. If insured damage delays commissioning, the developer not only incurs repair costs but also loses months of electricity sales. While the damaged equipment may be restored, the lost earning opportunity cannot simply be recovered by working faster.

Where Does DSU Insurance Fit in the Project Lifecycle?

DSU Insurance becomes relevant only during specific stages of a project.

This shows that DSU is intended to bridge the gap between construction risk and the start of commercial operations.

Understanding the DSU Claim Chain

One of the most misunderstood aspects of DSU Insurance is that not every delayed project automatically results in a claim.

A successful claim generally follows a clear chain of events.

Insured Physical Damage
⬇
Damage affects critical project activities
⬇
Construction or commissioning is delayed
⬇
Commercial Operation Date (COD) is postponed
⬇
The delay leads to measurable financial loss
⬇
DSU claim may become payable (subject to policy terms)

If this chain is broken, for example, if the project is delayed due to labour shortages or permit issues rather than physical damage, the policy may not respond.

What Does DSU Insurance Typically Cover?

The exact scope depends on the policy wording, but DSU Insurance is generally intended to compensate financial losses arising directly from delayed project completion.

It may include:

Coverage begins only after the waiting period specified in the policy and continues for the agreed indemnity period.

Situations Where DSU May Not Respond

Many project delays arise from commercial or contractual issues rather than insured physical damage.

Examples include:

Understanding this distinction helps project owners avoid unrealistic claim expectations.

Why Documentation Matters During a DSU Claim

Unlike many insurance claims, DSU claims often require both engineering and financial evidence.

Insurers may review:

• Original construction schedule
• Critical path analysis
• Commissioning programme
• Site progress reports
• Surveyor's findings
• Procurement records
• Delay analysis reports
• Financial projections
• Revenue estimates
• Loan repayment schedules

Strong documentation helps demonstrate that the financial loss directly resulted from an insured delay.

Real-Life Project Example

A company is developing a 250 MW solar power project that is expected to commence operations in September.

During the testing phase, a fire damages the main transformer, delaying commissioning by nearly three months while replacement equipment is sourced and installed.

Although the engineering insurance policy pays for repairing the damaged transformer, the project owner also faces:

• Delay in electricity sales
• Continued interest payments on project finance
• Fixed operating expenses
• Reduced projected cash flow

Subject to the policy terms, DSU Insurance can help compensate for these financial losses because they arose directly from an insured event that delayed commercial operations.

How DSU Insurance Differs from Other Project Risks

Not every project risk is addressed by the same insurance policy.

This illustrates that DSU Insurance is one part of a broader project risk management strategy rather than a standalone solution for every construction delay.

Which Projects Benefit the Most from DSU Insurance?

DSU Insurance is particularly relevant where delayed commissioning can significantly affect revenue generation.

Projects commonly considering this cover include:

• Solar and wind energy projects
• Green hydrogen facilities
• Battery Energy Storage Systems (BESS)
• Transmission and distribution projects
• Manufacturing plants
• Industrial processing facilities
• Metro rail systems
• Airports
• Ports
• Large infrastructure developments

The greater the investment and expected cash flow, the more valuable delay protection becomes.

Questions to Ask Before Considering DSU Insurance

Before opting for DSU Insurance, project owners should evaluate:

• How much revenue depends on timely commissioning?
• What are the project's largest construction risks?
• Which equipment sits on the critical path?
• How long would major repairs realistically take?
• What financial commitments continue during a delay?
• Is the expected indemnity period adequate?
• Are project schedules and financial assumptions properly documented?

These questions help assess whether the project's financial exposure justifies additional protection.

Final Thoughts

Unexpected damage during construction not only affects the project site but it can also disrupt financing, postpone revenue, and delay business growth. For large EPC, industrial, and infrastructure projects, the financial impact of a delayed commissioning can sometimes be more significant than the physical damage itself.

Delay in Start-Up (DSU) Insurance addresses this gap by focusing on the financial consequences of insured construction delays. While it does not replace good project planning or contract management, it can form an important part of an overall project risk management strategy, particularly where timely commercial operations are critical to project success.
