It is a major mission for companies to reduce the workload of their employees and to pursue profit generation by improving the efficiency of work. Chugoku Electric Power Transmission & Distribution has been tackling this issue, and they outsourced part of their standardized wheeling charge* calculation services. As a result, they have successfully improved work efficiency and reduced work hours.
* Wheeling charge: A "transmission and distribution network usage fee” that a retail electric power utility company pays to a power transmission company.

Decided to introduce BPO to respond to changes in the power distribution business environment swiftly and appropriately

Chugoku Electric Power Transmission & Distribution Co., Inc. (hereafter referred to as Chugoku Electric Power Network) was spun off from the Chugoku Electric Power Co., Inc. following the amendment to the Electricity Business Act when it was enforced in April 2020. As a power utility company, the Company has reliably been providing electricity 24/7. Its Network Service Center (NSC) is playing a central role in communicating with retail power utilities, executing contracts such as wheeling supply agreement, calculating and collecting wheeling charges, and operating call centers.

Mr. Watanabe said, “The NSC has been organizing and enhancing its business operating structure since our company was spun off, however, we are experiencing a rapid increase in the number of inquiries and applications in line with the expansion of renewable energy implementation. A new wheeling charge system* was introduced in 2023 and other national level changes are being considered. Addressing these reforms is an important issue for us.”

* New wheeling charge system - Revenue Cap System: The government of Japan started to impose a limit in the revenue to general electricity transmission and distribution utilities, and the wheeling charge should be set within this limit. As a result, general electricity transmission and distribution utilities have to actively engage in improving efficiency and reducing cost.

Chugoku Electric Power Transmission & Distribution then decided to outsource part of its standardized wheeling charge calculation services to BELLSYSTEM24 to improve efficiency, starting October 2022 and progressing in stages. Mr. Watanabe said, “BELLSYSTEM24 has been our partner since February 2019 when we opened our NSC call center. They have also been responsible for the call center of our parent company, Chugoku Power Company, for almost 20 years. The major reason that we chose BELLSYSTEM24 was that they are already familiar with our business where we use a lot of technical terms and dedicated systems. Another reason was that we thought highly of their initiatives towards stable operation and ensuring quality. We thought BELLSYSTEM24 was the best partner for engaging in a new endeavor and we didn't think twice about choosing them.”

Complete documentation and training to ensure quality

In outsourcing wheeling charge calculation, their concern was whether they could maintain the same quality as before.

Mr. Kodama said, “Errors in wheeling charge calculation and invoicing would cause a great trouble to electricity retailers. We needed to do detailed preparations for this reason.” Another concern was that this BPO had few precedences in other general electricity transmission and distribution utilities.

Mr. Kodama said, “We didn’t find a lot of cases of outsourcing wheeling charge calculation work when we inquired with other power utilities. A major challenge was to build a scheme in a short period of time when there were few precedences to follow.”

In this context, Chugoku Electric Power Network and BELLSYSTEM24 jointly started to work on the following four points starting February 2022:

The first point was to prepare a timeline for outsourcing. Mr. Kodama said, “We started to prepare a timeline by selecting tasks that could be outsourced. We considered it thoroughly because the amount of work to be outsourced changes depending on the content and volume of each job. BELLSYSTEM24 also proposed taking an inventory of tasks, and started the preparation work together with Chugoku Electric Power Network.

The second point was for managers of BELLSYSTEM24 to learn to do the tasks. After managers from BELLSYSTEM24 learned the basics, they did the actual work along with employees of the Chugoku Electric Power Network. Mr. Kodama said, “I feel that those managers were able to acquire practical skills by learning both in classrooms and on the job.” Those managers also not only learned the work, but also improved and proposed the workflow. They learned the tasks as they aimed to improve the work efficiency.

The third point was to prepare a work manual. This is where the two partners placed the biggest efforts. NSC prepared the manual based on the current version prepared by the employees, and reflected employee-accumulated know-how as much as possible. This manual was reviewed by BELLSYSTEM24 and was edited to be the manual that covers all work procedures and should be followed to perform work efficiently.

Mr. Kodama said, “The new manual prepared by BELLSYSTEM24 made me realize that the old version had areas that were lacking from their point of view, even though we thought they were sufficient.”

Mr. Nagamoto said, "BELLSYSTEM24 helped us visualize what each employee was doing and their know-how, then consolidated and standardized this information so that it can be used to educate new employees. From the NSC's point of view, it's a great manual."

The fourth point was hiring and training of talent. BELLSYSTEM24 exercised its unique strengths here to put the finishing touches on the actual execution of work while using the manual as a base.

Mr. Nagamoto said, “BELLSYSTEM24 did their best to assign their talent who are familiar with our work, such as communicators who had worked for the Chugoku Electric Power. I think this makes the work go smoothly.”

Mr. Watanabe said, “We felt comfortable that BELLSYSTEM24 assigned our work to communicators who understand the knowledge and technical terms used in the Chugoku Electric Power and the NSC without us explaining from scratch.”

Having said that, the communicators sometimes had difficulty understanding some of the new work. To overcome this, BELLSYSTEM24 provided training sessions as we exchanged opinions with employees of the Chugoku Electric Power Network. Mr. Watanabe and Mr. Kodama reflected on this by saying, “A factor in our outsourcing starting successfully was that they communicated to us often. Also, our employees' knowledge increased due to the training and dissemination based on documentation.”

Documentation and BPO reduced work hours

Since starting BPO in October 2022, several results have emerged.

Mr. Watanabe and Mr. Kodama said, “The best thing that happened is that employees who were working on calculating wheeling charges can now work on enhancing and addressing other operations. We expect that we will have more new work to come, and we are ready because we now have the manpower.” At the same time, BELLSYSTEM24 was able to reduce the anticipated work hours because operations were consolidated and workflow was made more efficient as we prepared the manual.

Another major achievement was that operations were documented into the manual upon BPO.
Mr. Nagamoto said, “BELLSYSTEM24 standardized know-how that each employee has accumulated, and operations that were done differently by individual employees. I expect that this will make the work more efficient, as well as increase the stability of operations and improve the work quality.”

Continued review on BPO for further efficiency and quality enhancement

The NSC of the Chugoku Electric Power Network says they would like to continue reviewing the BPO going forward in order to improve the operational efficiency and the work quality.

Mr. Watanabe said, “We have a number of operations that need to be processed in different ways, such as work that uses dedicated systems and their auxiliary tools and work using paper-based forms. We will be addressing this issue for further digitization, paperless initiatives, and BPO as we review our wheeling system and computerization of our work. We are expecting BELLSYSTEM24, who have been working with us as partners, to make further proposals actively from an external viewpoint.”

Mr. Nagamoto added, “NSC is at the core of our organization. NSC handles various work including invoicing the wheeling charges and handling call center traffic as the organization closest to our customers. Our thinking to date has been that we do everything internally. However, some work can be done with higher quality and more efficiently if we leverage external help. We would like to consider further BPO.”

Mr. Watanabe said, “BELLSYSTEM24 accurately understands the challenges that we face, and addresses them appropriately and swiftly. They have been building an environment where it is comfortable to consult with them. I would like them to first establish stable operation and quality of the wheeling charge calculation services. Then I would like to see them make proposals that only BELLSYSTEM24, our long-time partner, can make.”
