Power plant construction and handover · Calculation Rules

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_reference	all inventory rows	Aggregate each attributable atomic quantity for this same accepted entity. q = Q / N, where N = 1 complete delivered plant; q is per declared reference flow. Do not divide by assumed plant mass, lifetime, cost or generated electricity.	cp_handover	per declared reference flow
calc_electricity	lv_power; mv_power	E_MJ = E_kWh * 3.6; preserve actual meter/gate and allocate construction energy once.	cp_utilities	MJ per declared reference flow
calc_density	fresh_concrete; diesel; sea_intake	Mass in kg = measured volume times independently evidenced same-material/state density in compatible units; retain raw volume and density provenance. Unknown density is review, not a guessed factor.	cp_civil; cp_utilities; cp_environment	kg per declared reference flow
calc_freight	road_freight	Sum actual cargo tonnes * actual route kilometres by leg, with supported shared-load and return convention; distinguish raw vehicle-km from t*km and included supply freight.	cp_transport	t*km per declared reference flow
calc_modules	poly_module; mono_module	For each same-configuration module lot, multiply measured gross area per module by attributable consumed count = gross attributable receipts + opening stock - verified returns/transfers - closing reusable stock; sum across lots under the same gross-area convention. Include modules consumed by damage, rejection and rework before acceptance. Record accepted installed area and count separately; reconcile discarded modules under cp_waste without subtracting their manufacture burden. Rated capacity and electricity remain distinct qualifiers/outputs.	cp_renewable	m2 per declared reference flow
calc_attribution	plywood_form; excavator; mobile_crane	Attributable asset manufacture = measured asset amount * evidenced share; cumulative shares across every beneficiary and period ≤1. Keep physical transfer ledger and operating fuel separate; unsupported use/lifetime denominator is review.	cp_assets	attributed asset amount per declared reference flow
calc_releases	fossil_co2; nitrogen_monoxide; nitrogen_dioxide; pm_fine; pm_coarse	Use measured emitted species mass or an independently supported source-specific site model. Fossil CO2 may use measured oxidized fossil carbon * 44/12 with composition/oxidation evidence; molecular NO and NO2 require independent speciation, and PM fractions are disjoint. No universal engine/plant emission factors are given.	cp_environment	kg per declared reference flow

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
configuration	reference product	Actual generating route, complete installed BOM, geography, capacity/geometry and delivery stage must describe the same identified plant.	cp_handover; cp_civil; cp_thermal; cp_nuclear; cp_hydro; cp_renewable
coverage	all inventory rows	Cover every actual work package, subcontracted interval and relevant route; disclose missing measurements, components, unsupported identities and all excluded stages without claiming complete lifecycle.	cp_handover; construction records; supplier gates
metrology	all inventory rows	Retain calibration, raw basis/state, density/composition provenance, dimensional consistency and uncertainty; no default mix, site consumption, plant mass or life.	cp_civil; cp_utilities; cp_environment; cp_transport
attribution	temporary; hydro; electrical	Persistent asset and multipurpose civil/interface allocations conserve burdens across all beneficiaries; unresolved denominator or scope stays review.	cp_assets; original project allocation ledger
source_limits	dataset	Historical technical sources support qualitative construction/route facts only, not current permission, default recipe, lifetime or emission factor. Nuclear, biomass, hydro, wind and solar case scopes must not be silently extended.	un-cpc-power-plants-2025; iaea-nuclear-construction-2011; ifc-thermal-power-2008; ifc-biomass-construction-2017; ifc-hydropower-2018; doe-wind-siting-2021; ifc-mocuba-solar-2016; epa-concrete-washout-2012

9. Validation Rules

rule_id	applies_to	rule	source_ids
identity_gate	dataset; inventory	Require one actual constructed power-plant entity, its generating route and all mandatory qualifiers. Verify every adopted identity against material/specification, geography, state, route, primary property and unit group; unresolved identity is not a substitution licence.
measurement_gate	dataset; inventory	The final output is exactly 1 item/件 and every inventory/protocol basis is the same declared reference flow. Reconcile measured geometry, capacity, count and delivery state; never infer mass per plant, life, energy yield or a universal mix. Preserve Mass, Area, Length, Volume and energy identities and evidence for any conversion.
completeness_gate	dataset; inventory	Match every actual required/conditional design work package to its atomic rows, original records and upstream/transport interfaces. Missing components, unmetered work, hot tests within the accepted scope, unknown allocations or conversions and unsupported routes remain review gaps and prohibit a complete result; genuine absence requires design evidence.
environment_gate	dataset; inventory	Check independent source/species/medium evidence before direct elementary exchanges, including fossil share, molecular NO/NO2, disjoint PM fractions and water receptor. Captured sludge/liquid is waste, internal recirculation is not intake, and noise/concentration is not assumed emitted mass. Missing observation is not zero.
attribution_gate	dataset; inventory	Reconcile each persistent asset and shared dam/connection ledger across all users, projects and periods; cumulative manufacture shares ≤1 and complete attribution sums to the whole declared burden. Retain actual gates and eliminate duplicate raw materials, equipment packages, fuel services and freight.
handover_gate	dataset; inventory	Require dated signed construction acceptance, geometry/configuration and outstanding-tests list. Independent structural, electrical, nuclear, environmental or regulatory acceptance must be evidenced where claimed; PCR inspection establishes none of these approvals. Report performed/skipped checks, findings, uncertainty and covered/excluded stages.

10. Published Dataset Profile

Field	Value
dataset_role	foreground_construction_dataset
downstream_use	Explicit construction contribution to a plant infrastructure model with separately matched upstream components and separately assessed operation/end of life
allowed_use	The measured actual plant/site/configuration/acceptance period and compatible comparisons with the same functional/coverage definitions
excluded_use	Generic mass-based power-plant material, unqualified per-kWh operation, default lifetime/capacity/recipe, whole lifecycle or licensing/approval claim
required_metadata	All reference qualifiers; actual work packages, initial state and scope; original unit/gate/identity bindings; measured geometries and capacity; asset/shared interface ledger; cold/hot and fuel-load status; signed handover dates
required_quality_disclosure	Performed/skipped checks, unmetered and unsupported scope, unresolved identity/allocation/conversion, uncertainty, supplier links and excluded operating/maintenance/demolition stages
update_trigger	Actual configuration, site, component/supply gate, method evidence, measurement, acceptance stage or attributable work changes
