The PI System: A Renewable Energy Solution for Now and the Future
Sempra Energy is one of the largest energy providers in the country. With over 3000MW of solar, wind, and energy storage, Sempra Renewables (a subsidiary of Sempra Energy) delivers renewable energy to over 32 million customers around the world. A few years ago, Sempra Renewables bought the rights to development of Great Valley Solar, which is a 200MW solar facility just outside of Fresno, CA. Spanning nearly 1200 football fields of solar modules, the vast complex will provide enough energy to power nearly 90,000 homes. Site construction was done in phases, resulting in four plants tied together with one single substation. Each of the plants as well as the Ocho substation had its own SCADA system used to control and manage each plant. Managing five different SCADA systems was already expensive, but an upgrade to an already cumbersome solution would prove to be even more costly. David Jeon, the Fleet Technical Manager at Sempra Renewables, needed another solution.
