Powering Peace of Mind

Featured employee's status up to date as of October 2019.

Though more often associated with the petroleum industry, Idemitsu is also involved in the generation and distribution of electrical power. Because storing electricity presents challenges, one of the most important aspects of the business is predicting the precise amount of energy needed at any given time. Forecasts are based on a number of metrics, including weather, temperature, and customer-usage patterns. Accurate predictions allow us to serve the needs of society and provide our customers with peace of mind.

The Lifeblood of Society

“My job is to help deliver the lifeblood of society,” explains Wataru Shiraishi of the Electric Power/Renewable Energy Business Division. There are two focuses within his division: predicting the ever-changing power-consumption volumes; and determining power-supply volume based on the forecasts. Every day, Waturu carefully determines the optimum balance between demand and supply – ensuring that the lifeblood continues to flow.

Accuracy Is Everything

As with weather forecasts, the accuracy of power-consumption predictions increases as lag time decreases. Therefore, Wataru refines his predictions up until the last possible moment. An error in the prediction or the decisions based on it could disrupt Idemitsu’s overall demand-supply balance. This is why, in addition to his day-to-day responsibilities, Wataru is fine-tuning predictive methodology in order to achieve an even higher level of accuracy.

You Don’t Even Think About It
Until the Lights Go Out

Power is an aspect of everyday living one tends to take for granted. People seldom consider the electricity that keeps their lights shining – until the lights go out. It can be a shocking realization. For this reason, Wataru works tirelessly to ensure that the lifeblood keeps flowing – that customers can enjoy their lives without thinking about the electricity that powers their peace of mind.

Supporting Society

Every year, there is an increase in the volume of electric power generated through renewable energy sources, such as solar and wind power. This makes the accuracy of Waturu’s predictions even more important. Additionally, it necessitates a flexible response to societal changes and their impact on Japan’s energy environment. It is a challenging task, but one he embraces. “I want to contribute to society,” Wataru asserts, “and I am proud to know that my work supports the people of Japan.”
