BPPT adopts Lacima Analytics for Japan Power Trading

A comprehensive market risk transformation enabling faster, more informed trading decisions across Japan’s dynamic power market.

The Project

Seeking to establish a single, trusted market-risk solution and align with Banpu’s group governance standards for its expanding Japan power trading desk, Banpu Power Trading G.K. (BPPT) engaged Lacima to implement a flexible analytics application delivering current exposure, trusted valuations, limit monitoring, and forward-looking scenario analysis.

Lacima Analytics was implemented to consolidate BPPT’s diverse portfolio, from balancing group and retail fixed-price contracts to Futures, Swaps, Options, Contracts for Difference (CFDs), and Financial Transmission Rights (FTRs), giving traders and risk managers the tools to measure, stress, and act on market risk quickly and confidently.

The Client

Banpu Power Trading G.K. (BPPT) is a subsidiary of Banpu Renewable. Singapore Pte. Ltd (BRS) under Banpu NEXT and operates within the Banpu Group’s electricity business in Japan. Based in Tokyo, BPPT manages energy trading and portfolio optimisation in the Japanese power market.

Banpu PCL, based in Bangkok, is a leading versatile energy company operating across nine countries in four business pillars under its Energy Symphonics Strategy: Next-Gen Mining, U.S. Closed-Loop Gas, Power+, and Future Tech, covering a broad portfolio of energy and technology businesses.

The Challenge

As BPPT’s trading activity grew, so did the complexity of managing risk across physical and financial positions. Existing legacy systems relied on manual data collation, limiting timely visibility of exposure, Mark-to-Market (MTM) values, and risk limits.

BPPT required a comprehensive, integrated Risk Management and Analysis Solution to:

• Consolidate all exposures and unrealised Profit and Loss (P&L).
• Track market-risk limits with alerts and threshold monitoring.
• Support Value-at-Risk (VaR), stress testing, and historical VaR simulation capabilities.

BPPT sought not only to measure exposure but to empower traders with insight – enabling faster, more confident decisions during periods of market volatility.

The Solution

Lacima Analytics acts as BPPT’s core market-risk and portfolio analytics application. Configured to align with the Japanese market and Banpu’s group’s governance standards, the solution delivers:

• Consolidated portfolio modelling across all Japanese power instruments.
• Integrated data feeds from trade and market systems for exposure and MTM.
• Portfolio analytics showing positions, limits, and (unrealised) P&L.
• Comprehensive Value-at-Risk (VaR) and scenario tools, including historical simulation and stress testing, to evaluate portfolio resilience under both real-world and hypothetical market conditions.

The system provides transparency, consistency, and analytical power, supporting BPPT’s continued growth in the regional energy market while laying the groundwork for future enhancements.

The Outcome

Lacima Analytics delivered a transformative uplift in market-risk visibility and control. BPPT now manages all exposures (physical, financial, and retail) within a single market risk application, providing rapid insight, improved accuracy, and faster decision-making.

Key outcomes include:

• Faster, data-driven trading and risk decisions.
• Improved accuracy in MTM and VaR reporting.
• Limit monitoring and breach reporting.
• Advanced risk insight through historical VaR simulation and stress testing, giving BPPT a clearer view of potential losses under extreme market conditions.

Lacima’s analytics are helping us bring all our Japan power exposures together within a single market-risk application, enabling us to see what’s driving our numbers. It’s a major step toward smarter, faster, and more confident market-risk management and trading decisions.”
