Start with the actual functional assignment
Targa describes an internship experience organized around a particular functional area, typically running from June to August. Its general program page does not provide a single role, pay rate or degree requirement for every participant. Use it to locate the appropriate opening, then read the exact assignment.
Midstream commercial and engineering work can interact closely. For a preparation exercise, commercial analysis asks what the volume, terms and costs imply; engineering analysis asks whether the physical design and operating constraints support the plan. This is a conceptual comparison, not a professional engineering instruction or a promise about an intern's authority.

Compare the questions each team would ask
Take a fictional proposal to serve additional volume. A business-oriented analysis might test demand assumptions, customer terms and revenue sensitivity. A technical analysis might identify constraints and the evidence required to assess capacity or reliability. Both should reject unsupported inputs, but they do not replace one another.
| Question | Commercial lens | Engineering lens |
|---|---|---|
| What is proposed? | Volume, customer need and commercial terms | Required performance and system boundary |
| What can go wrong? | Demand, price, cost or contract assumptions fail | Capacity, reliability or operating constraints are not met |
| What supports the decision? | Sourced assumptions and scenario economics | Approved technical evidence and review |
| What should an intern clarify? | Which analysis or reporting task is assigned? | What work is supervised and what qualifications are required? |
Build a scenario that respects the limiting input
A fictional service earns $0.50 per unit before costs. Expected volume is 100,000 units, but the exercise supplies a 90,000-unit capacity limit. The simple revenue calculation using feasible volume is $45,000, not $50,000. If unit operating cost is assumed to be $0.20, the modeled contribution before fixed costs is $27,000.
Now test volume of 70,000 and 90,000 while keeping unit assumptions constant. Contribution becomes $21,000 and $27,000. The difference is $6,000. This calculation does not establish actual capacity, contractual revenue, project value or an engineering design. The capacity limit is an input supplied for a teaching exercise.
List the missing information: timing, fixed costs, outages, contractual minimums, service quality and the evidence supporting demand. A good model does not silently fill those gaps with convenient assumptions.
Treat the worksite as part of the role
Read whether the internship is based in an office, facility or another location and what attendance or travel is required. Do not assume a headquarters address is the worksite. Ask about supervision and training before accepting work that touches physical assets. An analytical internship does not automatically authorize operational work.
For a student portfolio, use fictional inputs and a conceptual system boundary rather than private facility information. Do not publish layouts, operating details or employer data without permission. A clear business model and a list of questions for technical review can demonstrate judgment without pretending to certify a physical system.
Make your application specific to the function
For commercial work, explain an analysis of volume, price or cost with traceable assumptions. For engineering work, describe relevant coursework and a project you actually completed under appropriate supervision. For a mixed role, explain how you communicated a constraint across disciplines.
Search the exact function and degree requirement, then preserve the requisition and source date. Do not transfer benefits or deadlines from another Targa or energy-company role. The company guide can help with background, while the current employer posting controls the specific application.
