Option C — Phased Bridge: Mobile Now, Fixed Later
Many owners start demobilisable to prove load and cut early fuel burn, then civil-fix PV and thermal as the site matures. Phase 1: trailer PV + storage + inventory diesel night firming. Phase 2: expand BOP, permanent foundations, and larger thermal from inventory gas turbines. Phase 3 (where relevant): modular 45 MW-class gas platforms with slots from 2028 — see FX-45 longer-term firming and FX-45 overview.

When Each Option Wins
| Decision factor | Demobilisable trailer solar | Fixed hybrid | Phased bridge |
|---|---|---|---|
| Site dwell | Months to a few years; relocation likely | Multi-year permanent pad | Uncertain dwell; prove then fix |
| Civil risk | Low stranded foundations | Higher civil CapEx | Deferred civil until load proven |
| Fuel logistics | Daytime cut via PV; diesel for night | Same hybrid logic at larger scale | Start mobile; grow thermal later |
| Interconnection | Often island or weak-grid | May include grid code plant | Island first; interconnect later |
| Accountability | Needs single hybrid EPC | Needs single hybrid EPC | Needs one lifecycle partner across phases |

When Demobilisable Loses to Fixed — Decide Early
USP&E’s job as guide is to force that decision with load truth and dwell truth — then deliver either architecture under one EPC and O&M chain. Related reading: trailer PV camps · solar+diesel firming · gas turbine power stations.
Common questions
Is demobilisable solar the same as a temporary diesel farm?
No. Demobilisable solar adds relocatable PV and usually storage; diesel or gas remains the firming layer. The hybrid is designed as one plant.
Can a trailer camp become a permanent station?
Yes. Expand BOP, civil-fix PV/thermal, or add modular gas as load grows — under one lifecycle partner.
Do you publish efficiency or LCOE here?
No. , LCOE, or CF% on this page.
Why owners choose USP&E
USP&E is a full-service engineering, EPC and O&M company, not a broker. One team designs, builds and runs your plant, so nothing falls between contracts.
