Besides administering efficiency for each power plant under the power plant manager, we have an Operation Technical Service Department, which is responsible for monitoring, analysing, and assessing all power plant’s performance results and cooperating with each power plant, thus leading to continuous overall efficiency improvement.
Customer Relationship Management
At each power plant, a dedicated customer relations and operation management team that reports directly to the Head of Customer Service and Solutions. The team is responsible for regularly managing, monitoring, and analysing various data related to industrial customers and power plant operations, which directly reports to the Executive Vice President – Head of Industrial Customer Relations and Operation Management, with the key role of monitoring, providing information, coordinating, and gathering customer’s comments, expectations, or needs as well as business outlooks. The team works closely with the Sales Solutions department, as well as the B.Grimm Digital and Energy Solution division which both are under Co-President - Thailand Business and Energy & Industrial Solution Business to ensure their comprehensive understanding of customer’s needs, which lead to jointly pursue new solutions, and the formulation of strategies for product and service development to effectively and sustainably meet customer’s long-term expectations and needs.
Strategy
Customer Support and Flexible Commercial Terms
B.Grimm Power adopts a flexible approach to electricity payment and usage management to accommodate each customer’s specific circumstances. Customers may submit requests to deferred or make instalment payments on electricity bills if there is a valid reason on a case-by-case basis, particularly those facing unforeseen financial hardship. The company will engage in discussions and seek a mutual resolution with the customer before proceeding with any disconnection of service. Additionally, B.Grimm Power has a policy to waive penalties for customers whose electricity consumption falls below 65% of the contracted electricity volume, provided that a formal explanation is submitted for case-by-case consideration. These reflect our commitment to fostering sustainable partnerships with its clients in a balanced and context-appropriate manner.
B.Grimm Power also aims to enhance digital tools and services that allow customers to monitor their electricity usage in real-time, which may subsequently be applied to calculate an estimated payable amount as well as manage expenses more effectively — contributing to financial resilience and improved customer experience.
