The 'Enegaeru Biz,' an economic effect simulator for industrial-use self-consumption solar power and storage batteries provided by Kokusai Kogyo Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; President and Representative Director: Kyo Fujiwara; hereinafter 'Kokusai Kogyo'), has been introduced to NTT-ME Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; President and Representative Director: Takashi Ikeda; hereinafter 'NTT-ME'), which operates a comprehensive engineering business rooted in the region as part of the NTT East Group.
As a result of utilizing 'Enegaeru Biz,' NTT-ME has reduced simulation calculation time from approximately 3 hours to about 30 minutes. It has also become possible to provide rough proposals without demand data, and it is being used as one of the tools in proposal activities.
Background and Resolved Issues
Before the introduction, NTT-ME required approximately 3 hours per case for PPA unit price calculations using self-made Excel tools, and the proposal speed could not keep up with the increase in inquiries. In many cases, the demand data necessary for self-consumption simulations could not be obtained in the early stages of negotiations, causing the initial proposal phase to stagnate. Furthermore, calculations using different Excel methods by each person in charge led to personalization and quality variation, posing a major barrier to business expansion.
Main Effects of Introducing 'Enegaeru Biz'
1. Simulation time reduced from '3 hours' to '30 minutes'
Repetitive tasks such as weather data acquisition, setting confirmation, and recalculation are no longer necessary, reducing calculation time per case to 30 minutes. Even for municipal projects involving multiple facilities, preparation time has been significantly shortened, allowing more time to focus on essential proposal activities.
2. Demand templates enable rough proposals without data
By utilizing demand templates according to facility type, it is now possible to present rough simulations even before data acquisition. This allows specific figures to be shown in the early stages of negotiations, enabling early approach to decision-makers including section manager class and above.
3. Improved proposal accuracy with business simulations including storage batteries
Business feasibility calculations including storage battery capacity, which were difficult with conventional Excel tools, are now possible from the rough estimation stage. This helps suppress discrepancies with later formal quotations and improves the accuracy of explanations to customers.
