Press Release: TESLA Asia Pacific, Skipping Stone, and PRMS Launch Innovative Electricity Market Forward Curve Software for the Japanese Market

Tokyo, JP (July 18, 2023)

Announcing the Partnership

TESLA Asia Pacific (TESLA), Skipping Stone, and Power Risk Management & Solutions (PRMS) are pleased to announce their partnership and collaboration to develop and now offer Japan Market Forward Curves software. The partnership combines the extensive risk management and Japan power trading expertise of PRMS, the global risk management expertise of Skipping Stone and the energy forecasting and software development expertise of TESLA.

Features of Japan Market Forward Curves

The Japan Market Forward Curves are available for both Tokyo and Kansai with half-hourly values that extend over a two-year horizon. Curve data is refreshed daily after futures market closing. The Japan Market Forward Curve is unique in that it is assembled from more accurate market rather than fundamental data. Globally forward curves are a foundational element used for customer pricing, trading strategies, hedging, portfolio valuation, mark to market calculations and a host of standard risk management uses.

How to Access the Japan Market Forward Curve

TESLA is offering multiple ways for customers to access The Japan Market Forward Curve. It can be added to the TESLA Japan bundle or purchased ala carte. Clients can view the curve on TESLA’s market leading visualization platform and access it via API for easy integration with customer supply, pricing, analytics and risk systems.

Expert Opinions

Ryutaro Sameshima, Founder and CEO of PRMS Inc., stated, “This collaboration represents a significant milestone in power risk management methodology for the Japan market. Together, we will deliver a service that leverages advanced forecasting technologies, risk analysis methodologies, and industry-leading expertise to provide clients with unparalleled insights and strategies.”

“The Japan Market Forward Curve is a major enhancement to TESLA’s Japan offering. It compliments fundamental load, weather and intermittent generation forecasts we already provide to give users a much more robust view of the market,” said Tetsuya Totsuka, Japan Business Development Manager of TESLA Asia Pacific Ltd.

“As we advise Japanese energy companies on global risk management best practices, it became obvious a gap in the tools available in Japan was market based forward curve software. To fill that gap this collaboration pulled from Mr. Sameshima’s modeling expertise, TESLA’s leading forecasting solutions and our global knowledge of how to utilize the tool,” said Hiroshi Okuyama, Skipping Stone, GK President. “The Japan Market Forward Curve is a step toward Japanese power companies having access to best practices tools that are modified to fit Japan’s unique market structures,” continued Mr. Okuyama.
