Solar energy co-exists with agriculture through ACEN’s agrivoltaics program

ACEN’s solar farms in the Philippines have piloted an innovative, collaborative and interdisciplinary program which aims to support the energy transition while helping provide food security and livelihood opportunities to local communities.

Agrivoltaics is the simultaneous use of land to generate solar energy and produce agricultural products, addressing the dual need to transition to clean energy and increase food supply. In this symbiotic farming system, the plants help keep the solar panels cool, making them more productive by generating up to 10% more electricity, and allowing for more solar energy to be harnessed.

ACEN power plants awarded IMS certification

ACEN’s operating power plants in the Philippines were recently awarded the prestigious Integrated Management System (IMS) certification as verified by DQS Certification Philippines, Inc., one of the leading certification bodies for management systems worldwide.

Nine of ACEN’s operating plants have passed the IMS certification for:
• ISO 9001:2015 (Quality Management System)
• ISO 14001:2015 (Environmental Management System)
• ISO 45001:2018 (Occupational Health and Safety Management System)
