Completing an infrastructure project is about much more than finishing construction. The real milestone is the day the project begins generating revenue. Whether it is a solar park, a transmission line, a manufacturing facility, or a metro project, the commercial operation date is often tied to loan repayments, investor returns, customer commitments, and long-term contracts.

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.
Project Stage
Typical Risk
DSU Relevance
Design & Planning
Design revisions
No
Procurement
Supplier delays
Generally No
Construction
Fire, flood, collapse, accidental damage
Yes
Installation & Testing
Equipment damage
Yes
Commissioning
Damage delaying commercial operation
Yes
Operational Phase
Normal business interruption
No
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:
Financial Loss
Purpose
Loss of anticipated gross profit
Compensates expected earnings lost due to delayed operations
Continuing fixed expenses
Helps cover unavoidable operational costs
Loan interest or financing charges
Reduces the financial burden of delayed commissioning
Standing charges
Covers certain ongoing commitments during the delay
Additional insured financial losses
Subject to policy wording
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:
Situation
Typical Position
Labour shortages
Usually not covered
Delayed statutory approvals
Not covered
Contractor insolvency
Generally excluded
Poor project planning
Not covered
Material procurement delays
Usually excluded
Contractual disputes
Not covered
Design changes without physical damage
Generally excluded
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.
Risk
Typical Solution
Physical damage during construction
Engineering Insurance
Transit damage to equipment
Marine Cargo Insurance
Delayed commissioning due to insured damage
DSU Insurance
Contractor performance issues
Contract management
Regulatory delays
Project planning
Liquidated damages
EPC contract provisions
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.
