ConEd's district steam system has over 1,550 steam customers in Manhattan and 100's of million square feet in its service territory. It is the most expensive way to purchase hot thermal energy for a building available on a cost per delivered therm bases ($3 to $6 per equivalent therm for commodity only). The steam system opened in the 1880's and has distribution piping installed before 1906. Now is the time to consider if the district steam system can de-carbonize in a cost effective sustainable manor before we waste capital on a pipe dream. The current 2021 to 2031 10-year plan does not start to address electrification until the end of this decade in year 2029. The investments are primarily cost of doing businesses usual. These repairs are essentially to keep the system open. We should ask if ConEd's assumptions about carbon capture and sequestration, availability of green hydrogen, and renewable natural gas realistic? Everyone is looking for easy silver bullet instead of doing the hard un-glamorous work of of de-carbonizing building the old fashion NESEA way one sustainable building at a time. Con Edison has not even made any projections of the cost of steam compared to other technologies available in it 10 year plan. The impact of this will impact the affordability of living in Manhattan for low and medium income families, college students, and young professionals.
