By implementing measures to achieve ACA Level 4+ certification, Mumbai Airport set an example, showcasing the potential of sustainable practices within the aviation industry. These actions pave the way for a more environmentally conscious and responsible approach to airport operations, emphasising the importance of sustainability and encouraging other stakeholders to follow suit. The Mumbai Airport’s commitment to sustainable practices serves as an inspiration to the industry, driving change. CASE STUDY AEML supplying green electricity Adani Electricity Mumbai Limited (AEML), a majority-owned subsidiary of Adani Energy Solutions Limited (formerly Adani Transmission Limited) is an integrated utility. It serves over 12 million consumers spread across 400 sq. km in Mumbai and its suburbs. It achieved over 30% renewable power for its entire customer base in FY 2022-23 from a baseline of 3% in 2019. The switch in resources represented the start of a long-term trend to evolve the resource mix from fossil fuels to clean energy. AEML entered into long-term renewable power purchase agreements to reduce costs. Besides, the Group intends to increase the portion of renewable energy in its resource mix to 60% by 2027. This would be the next decisive trigger in moderating tariff, enhancing consumer value and helping make the world cleaner. In FY 2022-23, the Group witnessed a substantial increase in the adoption of renewable energy across its portfolio companies. The Group increased significantly from 0.23 million GJ in FY 2021-22 to 1.82 million GJ in FY 2022-23. This surge in renewable energy utilisation was primarily attributed to Mumbai International Airport Limited’s decision to consume 100% green energy by paying an additional tariff to the discom (distribution Group). Another noteworthy achievement by AGEL almost 85% of its energy requirement from renewable sources. In addition to drawing green electricity from the grid, Adani businesses commissioned rooftop solar systems. AGEL the pack at 85% renewable energy consumption, setting a high Adani Group standard. Green energy from grid and rooftop solar systems The Adani Portfolio is viewed as a progressive organisation, pursuing decarbonisation through renewable energy and low carbon alternatives.
