DAPR Assembly

Overview

The Distribution Annual Planning Report (DAPR) is a regulatory obligation under NER clause 5.20A. DNSPs must publish a DAPR annually, providing a 5-year forward view of network planning, demand forecasts, and connection opportunities. The DAPR is a significant document (typically 100–200 pages) that requires input from multiple teams across the DNSP.

Energy Copilot’s DAPR Assembly module automates data compilation and AI-generates narrative sections, reducing the time to produce the DAPR from weeks to days.

DAPR Structure

A DAPR comprises eight main sections:

Section	Content	Energy Copilot Module
1. Network Overview	Asset register, key statistics	Asset Intelligence
2. Demand Forecast	5-year demand forecast by zone	Demand & Weather ML
3. Network Capability Statement	Transfer capacity, constraints	Hosting Capacity
4. Planned Network Investments	Approved augmentation projects	Asset Intelligence
5. Connection Opportunities	Available capacity for new connections	Hosting Capacity
6. Non-network Alternatives	DER, demand response options	DER Management
7. REZ Assessment	Contribution to Renewable Energy Zones	Data → ISP
8. Compliance Checklist	NER 5.20A mandatory content checklist	Compliance

DAPR Builder (`/dnsp/dapr/builder`)

The DAPR Builder is a guided, step-by-step workflow:

Select DNSP and reporting year — loads all data for that DNSP
Review auto-compiled data — each section shows auto-populated figures with sources
Generate narrative — Claude Sonnet 4.5 generates draft text for each section
Edit and approve — engineers review and edit AI-generated content
Compile and export — outputs a formatted Word document or PDF

Demand Forecast Section

The DAPR demand forecast is produced from the ML demand model:

-- DAPR demand forecast extract
SELECT
    zone_id,
    zone_name,
    forecast_year,
    low_demand_mw,
    medium_demand_mw,       -- P50 forecast
    high_demand_mw,
    peak_demand_mw,         -- Maximum annual peak (P10)
    der_offset_mw,          -- Demand reduction from behind-the-meter DER
    net_system_load_mw      -- Medium demand minus DER offset
FROM energy_copilot.gold.dnsp_dapr_demand_forecast
WHERE dnsp_id = 'AUSGRID'
  AND forecast_year BETWEEN 2025 AND 2030
ORDER BY zone_id, forecast_year;

Network Capability Statement

The network capability statement documents the transfer capacity of each major interconnection into each zone:

Zone: BANKSTOWN (132/33kV substation)
Firm capacity: 180 MVA
Non-firm capacity: 220 MVA
Current peak demand: 152 MVA (84% of firm capacity)
5-year forecast peak: 165 MVA
Forecast headroom: 15 MVA
Augmentation trigger: 2027 (when forecast peak exceeds firm capacity)

Compliance Checklist

NER 5.20A specifies 42 mandatory content requirements for the DAPR. Energy Copilot maintains a checklist that maps each requirement to specific sections of the document:

GET /api/dnsp/dapr/compliance-checklist?dnsp=energex&year=2025

# Returns:
{
  "mandatory_items": 42,
  "items_met": 39,
  "items_pending": 3,
  "items": [
    {
      "requirement_id": "5.20A.a",

}

AI-Assisted Narrative Generation

Each DAPR section has an AI-generation endpoint that produces compliant, professional text:

POST /api/dnsp/dapr/generate-narrative
{
  "dnsp": "ausgrid",
  "section": "demand_forecast",
  "year": 2025,
  "data": {
    "total_zones": 47,
    "average_demand_growth_pct": 1.2,
    "highest_growth_zone": "Western Sydney",
    "highest_growth_pct": 3.8,
    "der_penetration_pct": 28
  }
}

# Returns AI-generated paragraph:
# "Ausgrid's network area is forecast to experience average demand growth
#  of 1.2% per annum over the 2025–2030 period, consistent with the
