Pre-feasibility studies & Detailed Project Reports

The document capital is committed against. It should survive hostile review by a lender’s technical advisor.

Consultancy · In short

A pre-feasibility study establishes whether a power project is worth developing; a Detailed Project Report (DPR) is the document a board sanctions capital against and a lender appraises. Enersys Engineers prepares both, covering site and logistics assessment, technical configuration, single-line diagrams, equipment schedules, civil and structural scope, statutory clearance route, implementation programme, capital cost estimate and levelised tariff computation.

Pre-feasibility study

A short, decision-focused document. Its job is to kill weak options cheaply and identify the one or two configurations worth spending real money to develop.

  • Screening of candidate sites against grid, fuel, water and land
  • Indicative capacity and technology options
  • Order-of-magnitude capital and operating cost
  • Evacuation feasibility and likely connectivity route
  • Principal risks and the studies needed to close them

What a Detailed Project Report contains

Project definitionCapacity, technology, configuration, fuel or resource basis and design life.
Site & logisticsSurvey, geotechnical findings, access, water source, fuel or resource logistics, land status.
Technical schemeProcess description, heat and mass balance where applicable, single-line diagram, plant layout and general arrangement.
Electrical systemVoltage selection, switchgear ratings from the fault level study, protection philosophy, earthing and auxiliary power.
EvacuationSwitchyard configuration, evacuation voltage, line route, connectivity and metering scheme.
Civil & structuralFoundation basis, main plant buildings, control room, cable trenches, roads and drainage.
Statutory routeClearance map with the sequence and lead time for each approval.
ImplementationPackage split, contracting strategy, milestone programme and critical path.
Cost estimatePackage-wise capital cost, IDC, contingency and operating cost.
Financial analysisLevelised tariff, sensitivity to capital cost, generation and fuel or tariff assumptions.

Why DPRs get rejected

A DPR fails technical appraisal for a small number of recurring reasons. We write against them deliberately.

  • Evacuation treated as an afterthought, with no confirmed bay or connectivity route
  • Switchgear ratings not traceable to a fault level calculation
  • Programme that assumes statutory approvals run in series after award rather than in parallel
  • Capital cost estimate without a package-wise build-up
  • Generation or PLF assumptions with no stated basis
Questions

Frequently asked

How long does a DPR take to prepare?

For a defined site and capacity, typically six to twelve weeks depending on whether geotechnical investigation and survey are already complete. Where site selection is still open, add the screening and survey period.

Can the DPR be used for lender appraisal?

Yes — that is what it is written for. The cost build-up, programme and generation basis are presented so that a lender’s independent engineer can verify each assumption rather than take it on trust.

Do you prepare DPRs for transmission and substation projects?

Yes. For transmission the DPR covers route selection, tower type distribution, soil and foundation basis, right-of-way assessment and stringing methodology. For substations it covers bay configuration, transformer sizing, fault level, protection philosophy and civil scope.
