Use Case: WESM-Compliant Energy Billing Automation (eBillsync)

Client: TeaM Philippines Energy Corporation (TPEC)
Industry: Energy / Retail Electricity Supply (RES)

Business

TeaM Philippines Energy Corporation (TPEC) TPEC is the retail electricity arm of TeaM Energy Corporation, one of the largest independent power producers in the Philippines. They operate major power plants (such as the 735 MW Pagbilao Power Station) and provide dependable energy solutions to a wide array of contestable customers across the country.

Challenge

As the Philippine energy market evolved, TPEC’s manual operations became a bottleneck for growth. Key obstacles included:

• Regulatory Complexity: Constant policy updates from WESM, ERC, and DOE required manual adjustments to billing logic.
• Manual & Error-Prone Invoicing: Managing diverse pricing structures for a large customer base using spreadsheets led to data silos and human error.
• Complex Data Integration: Manually gathering settlement data (CRSS), meter readings, and market prices (IEMOP) was time-consuming and difficult for non-technical staff.
• Security Risks: Sharing sensitive customer data and pricing via email and Excel sheets created significant data security vulnerabilities.

Solutions

Exist Software Labs implemented eBillsync, a WESM-compliant energy billing system, integrated with a centralized Data Warehouse:

• End-to-End Billing Automation: Automated the entire “Meter-to-Cash” cycle, including the generation of BIR-compliant electronic invoices.
• Real-time Market Integration: Built API connectors to automatically pull MMS and IEMOP market data, removing the need for manual data scraping.
• Dynamic Pricing Engine: Created a flexible system to manage variables like the Global Coal Index, Forex, and CPI, allowing for automated, complex contract calculations.
• Advanced Analytics: Leveraged a Data Warehouse to provide interactive dashboards (via Tableau/Power BI) for better decision-making on spot prices and quantities.

Benefits

For the Business (TeaM Energy):

• Operational Agility: Significantly shortened the time required to process thousands of data points, particularly for Line Rental and NSS (Net Settlement Surplus) allocations.

For their Customers:

• Billing Transparency: Customers receive accurate, easy-to-understand billing statements that clearly break down market-driven costs and determinants.
• Faster Response Times: Automated processes allow TPEC to resolve billing inquiries faster and provide more flexible, customized pricing plans.

Reliable Partnership: Higher operational efficiency ensures that TPEC remains a stable, tech-forward energy provider capable of meeting long-term power requirements.
