Anonymized sample — format and depth match a real delivered report; the project itself is fictional. Every score, scenario, and finding below runs through DurationX's actual scoring workflow against this fictional project, the same workflow every paid audit uses.

Sample decision brief

Meridian LDES 12h (sample)

100 MW · 12 h target duration · ES · Greenfield near 220 kV line · Solar shifting + evening peak supply (mixed, peak shaving-anchored)

Section 1 · Project snapshot

Project: Meridian LDES 12h (sample)
Country / site: ES · Greenfield near 220 kV line
Use case: Solar shifting + evening peak supply (mixed, peak shaving-anchored)
Power: 100 MW
Target duration: 12 h
Reliability: High availability required for evening peak commitments

Section 2 · Readiness

61/ 100

Conditionally ready

Section 2 · Confidence

Mediumband

Missing evidence lowers confidence first, readiness second — kept as two separate numbers, never blended into one grade.

Section 3

Top assumption failures

Technology Class Fit

Lithium-ion NMC's benchmarked core duration range is 2–8 h; the declared 12 h target falls outside that range.

6.0 of 39.0 points at stake in this component

Duration Justification

The 12 h duration target was declared without a sourced basis (e.g. a load-duration curve or vendor duty-cycle study) to justify that figure over a range.

5.4 of 39.0 points at stake in this component

Capex Completeness

The declared CAPEX figure does not confirm coverage of: integration, interconnection.

4.5 of 39.0 points at stake in this component

Section 4

Scenario comparison

#	Scenario · read	Readiness	Confidence
1	Customer baseline customer-provided · The customer's own declared configuration — the reference point every comparison below is measured against.	61	Medium
2	Duration alternative (5h) benchmark comparison · readiness delta +6 · appears modestly stronger under current assumptions	67	Medium
3	Alternative class: Vanadium redox flow benchmark comparison · readiness delta +4 · appears modestly stronger under current assumptions	65	Medium

Up to five scenarios per report: the customer's own configuration plus comparisons — 3 shown here.

Section 5

Technology-class implication

The declared class (Lithium-ion NMC) has a core viable duration range of 2–8 h. At the customer's target of 12 h, the class is outside its core range — class-fit component scored 70 / 100 under the current rubric. Class maturity is commercial; the pinned benchmark set records cycle life 5000 and calendar life 12 years for this class. These values feed the operational-pattern and delivery-maturity sub-checks in Section 2. The declared use case (Solar shifting + evening peak supply (mixed, peak shaving-anchored)) matches the class's allowed use-case set (arbitrage, peak shaving, ancillary services). Comparisons in Section 4 evaluate CLASSES against the same intake — not vendors, not brands, not specific products (const §6.5 vendor independence).

Section 6

Required next inputs

Expected commissioning date — up to 3.0 readiness points available (Delivery and procurement maturity, 10% weight)

Section 7

Investment-committee memo

Recommendation: Do not proceed to vendor selection yet — continue once the items below are resolved. Readiness is 61/100 (Conditionally ready), confidence is Medium.
Primary constraint: Technology Class Fit — Lithium-ion NMC's benchmarked core duration range is 2–8 h; the declared 12 h target falls outside that range.
Before the next diligence step: expected commissioning date — up to 3.0 readiness points available (Delivery and procurement maturity, 10% weight)

Section 8

Disclaimer and provenance

DurationX provides a vendor-independent, human-quality-controlled assessment of the readiness of assumptions submitted for a long-duration energy-storage decision. The assessment is tied to the project, location, inputs, benchmark dataset, methodology, rubric, and report versions identified in the report and to information available on the stated evaluation date. DurationX does not independently verify every customer-provided fact and does not provide engineering design or sign-off, fire or electrical safety certification, interconnection approval, permitting advice, vendor selection or procurement advice, legal or tax advice, investment advice, a valuation, a bankability opinion, or project due diligence. Scores and labels are not probabilities of success and do not guarantee cost, schedule, performance, availability, revenue, returns, financing, regulatory approval, or any other outcome. Public and licensed benchmark information may be incomplete, delayed, model-based, geography-specific, or subject to source restrictions and revision. Missing or non-comparable data are reported as not evaluable and must not be interpreted as favourable or unfavourable evidence. Decisions remain the responsibility of the customer and its qualified advisers.

This is an illustrative sample — it is not linked to a real delivered report and does not carry a verifiable signature. A real DurationX report is Ed25519-signed and can be independently checked at /verify using its report ID and verification reference; see the methodology page for how that works.
