Aveva Connect PI

Challenge

Billing for 70+ renewable energy producers ran on manual spreadsheets, with curtailment data scattered across systems and no unified view of 12 wind farms.

Key issues included:

• Manual, Excel-based billing across 70+ renewable energy producers
• Curtailment data scattered across systems, with no unified view of 12 wind farms
• Complex multi-tiered pricing and reconciliation across 3–4 month billing periods
• New capacity data needed to flow from PI/Aveva into invoicing and dashboards in real time
• Fragmented, manual coordination of desired-output requests across generation units

Solution

We delivered two Azure platforms on a shared foundation, integrating deeply with Aveva Connect PI for real-time data.

The solution included:

• Windvoice Calculator: full-stack Azure billing platform (React, GraphQL, SQL Server) automating the invoice lifecycle
• Curtailment Dashboard: event-driven Azure Pub/Sub architecture with real-time visibility across 12 farms
• Deep PI Data integration via Aveva Connect APIs, feeding both billing and live curtailment views
• Shared foundation: Azure AD auth, RBAC, audit logging, and agentic SDLC delivery
• Power Generation Comms Platform: real-time coordination with automated acceptance workflows

Results

Manual processes gave way to automated, real-time operations.

• Eliminated manual Excel billing across 70+ producers
• Real-time visibility across 12 wind farms
• 80% less manual reconciliation
• Eliminated manual phone/email coordination
