Energy Contracts to Finance Public Batteries
How a city, county, state, school, airport, housing agency, nonprofit or federal agency can pay for a battery from the savings it makes, with an energy savings performance contract (ESPC) or a utility energy service contract (UESC), and why 25 years of operations and maintenance decide the outcome. Worked examples from New York, New Jersey and California. 174 pages, 58 figures and 334 cited sources (statutes, regulator orders, federal program guides and official data), each listed with its web address and the date it was accessed. A PDF download is on the page.
Governance and Operations of Thermal Energy Networks
A guide for states, cities and their partners to three linked choices for a thermal energy network (TEN): who owns it, how it sells service and how it is paid for. It covers state law, owner types, lessons from power, water and district energy, bonds, paying a network back over 40 to 60 years and a checklist, with worked examples from Baltimore, New York City and Boston. 63 pages, 20 figures and 128 cited sources (statutes, regulator orders, IRS rulings and official reports), each accessed September 30, 2026. A PDF download is on the page.

Gaiergy Grid Studio: How Big a Battery Fits on a New York Circuit
Gaiergy's own feeder study tool. It runs the Electric Power Research Institute (EPRI) OpenDSS power flow engine on National Grid's public circuit data to find the equipment a battery needs to charge and discharge at a chosen point. Five real New York connection points show that the voltage of the line decides how big a battery fits. Screening results on ESTIMATE inputs; the utility sets the real answer in its own study.

ICAP Capacity Payments Under New York VDER: Alternatives 1, 2 and 3
How New York's investor-owned utilities pay a 5 MW battery for capacity under Value Stack Alternative 3, how solar and wind are paid under Alternatives 1 and 2, the summer discharge plan that covers the one hour that counts, and what the 2027 rate may do.

Two Electricity-Demand Panics, Twenty-Five Years Apart
In 1999 the forecasts said the internet would consume half the grid. It did not. Today the same certainty attaches to artificial intelligence and data centers. This paper compares the two episodes.
