How much does ESS cost per substation?
Twenty-five percent (25%) demand reduction would result in $166,140 annual savings per substation. The maximum ESS cost to realize a 10-year ROI would be approximately $1,661,400 per substation (based on current demand power rate). Avoided Generation Capacity Costs (AGCC).
How much power would a 7 line substation use a day?
Peak demand on the 7 Line is approximately 26 MW for 2 hours, twice per day. A 25% reduction in demand would require a total of 26 MWh of storage recharged overnight. Control would be based on power draw at each individual substation. Figure 11. Power Demand at the Roosevelt Avenue and 78th Street Substation During a Weekday
How can energy storage be used in a traction power system?
Energy storage can be used to store energy that would otherwise have been consumed by the resistor banks, and then released back into the traction power system when there is sufficient electrical load. If all resistor energy could be recovered using ESS the total annual savings for the 7 Line would be 6,335,164 kWh or about $886,923.
How is energy storage used in energy recovery applications?
In energy recovery applications, energy storage is used to reduce energy consumption through the capture and release of regenerated energy from rolling stock. Typically, energy produced by the train during braking is consumed by other trains operating in the vicinity.
How much would a 25% reduction in peak demand save a substation?
A 25% reduction in peak demand power across the 7 Line would save 78000 kW of demand power and approximately $2,159,820 in demand charges annually. Twenty-five percent (25%) demand reduction would result in $166,140 annual savings per substation.
