Additional information
Once fully operational these Bloom Boxes are expected to produce over 62 million kWh of energy annually—enough to power over 5,600 homes per year. The Bloom Energy installations will be deployed at 11 AT&T facilities in California including: Corona, Fontana, Hayward, Pasadena, Redwood City, Rialto, San Bernardino, San Diego, San Jose, and San Ramon.
Bloom Boxes contain stacked fuel cells and will convert air and natural gas into electricity through a clean electrochemical process. The high efficiency of the Boxes will help AT&T avoid approximately 250 million pounds of CO2 emissions, equivalent to removing over 3700 cars from the road.
Methodology
All publicly-announced energy storage projects included in this analysis are drawn from GlobalData’s Power IC. The information regarding the projects are sourced through secondary information sources such as country specific power players, company news and reports, statistical organisations, regulatory body, government planning reports and their publications and is further validated through primary from various stakeholders such as power utility companies, consultants, energy associations of respective countries, government bodies and professionals from leading players in the power sector.
