Solar SCADA System

In the past decade, Thailand energy demand has been rising at 5% annually. Because of the limited fossil fuel, Thailand depends highly on energy imports. On the other hand, Thailand has rich sunshine resource, so the authorities concentrate on the development of solar power. In 2010, the government started the 55MW Solar Farm project, and spanned up to 84MW in 2013. 3onedata’s real-time monitoring system plays a very important role to ensure the safe and stable running of the power generation system.

Overview

Challenge
