On 28 June 2024, Casio (Thailand) Co., Ltd., signed a Private Power Purchase Agreement (Private PPA) with Marubeni Green Power for a solar rooftop project with a capacity of 999.18 kWp. This represents a significant milestone in adopting sustainable energy solutions. The solar rooftop will be installed on the factory roof of Casio (Thailand) Co., Ltd. located in Chok Chai District, Nakhon Ratchasima.
Casio (Thailand) Co., Ltd. is part of the global Casio Group, well-known for its innovative timepieces and calculators. The company is especially famous for its G-SHOCK brand, known for its durability and advanced technology.
With the Private PPA scheme, Casio will not incur any initial investment for the solar system. Marubeni Green Power will manage the installation, maintenance, and operation throughout the contract term. It allows Casio to secure great benefit from clean energy without CAPEX and OPEX.
The solar installation is expected to significantly reduce energy costs and greenhouse gas emissions. It’s estimated to reduce CO2 emissions by approximately 618 metric tons per year This reduction is comparable to the yearly emissions of around 134 passenger vehicles, according to average vehicle emissions data from the U.S. Environmental Protection Agency (U.S. EPA).
