The Belgian energy sector is undergoing rapid change. Regulatory compliance, market volatility, and digital transformation are reshaping how suppliers operate. Tactical Advisory Group partnered with a major energy supplier to deliver projects that ensured compliance with international standards, improved operational efficiency, and strengthened data governance.
After the acquisition of the energy supplier by a listed company, compliance with International Financial Reporting Standards (IFRS) became mandatory. This required implementing a marked-to-market accounting system for B2B clients, ensuring accurate valuation of positions at risk and transparent cost allocation across business units.
At the same time, the integration of two major energy portfolios demanded a complete overhaul of forecasting and reporting tools. Data quality issues, outdated systems, and fragmented processes posed significant risks to operational margins in a highly volatile market.
Tactical Advisory Group deployed a multidisciplinary team of consultants with expertise in business analysis, functional design, data analytics, and project management. The team’s strength lay in its flawless coordination, with each consultant knowing their role, building on one another’s expertise, and together delivering measurable impact.
For the market-to-market compliance project, our team defined the project approach, validated assumptions, and designed solutions in close collaboration with the client. They coordinated sensitivity and variance analyses and supported initial dry runs to ensure accuracy.
In parallel, other consultants focused on portfolio integration and forecasting. This involved extensive data cleaning, rationalizing assumptions, and implementing a reliable forecasting tool using SQL and Excel. Later, a new Profit and Loss tool was developed to calculate the market value of the merged portfolio, impacting procurement, sales, finance, and BI teams.
Finally, our data analyst and team manager addressed operational inefficiencies caused by poor data quality and outdated tools. They replaced legacy forecasting and P&L tools with high-performance SQL solutions, reducing lead time from one day to one hour. They also improved commodity cost estimation and optimized calculation hypotheses. Data quality was enhanced across a sales database of 5.4 million records, while managing a data team to ensure prioritization and alignment across departments.
The client achieved full IFRS compliance through a robust market-to-market accounting system. Forecasting processes became significantly faster and more transparent, reducing lead time from one day to one hour. Data quality improved across millions of records, ensuring reliable information for procurement and margin protection. These changes positioned the client for future growth and integration of innovative energy services.
At Tactical Advisory Group, we combine strategic insight with operational excellence. Our consultants bring sector-specific knowledge, proven methodologies, and a commitment to delivering measurable results. For energy suppliers in Belgium and beyond, we are the trusted partner for projects that matter.
