How does this company make money?
Eversource earns a regulated rate of return on the infrastructure it owns — wires, substations, and transmission equipment — with the allowed return set separately by Massachusetts DPU, Connecticut PURA, and New Hampshire PUC through periodic rate cases. On top of that, customers pay a per-unit charge based on how much electricity they use. The cost of the wholesale electricity itself, sourced through ISO New England, is passed through to customers as a separate line item rather than kept as profit.
What makes this company hard to replace?
State regulators have granted Eversource an exclusive territorial franchise, which means no other provider is legally permitted to deliver electricity to customers within those boundaries. The poles, wires, and substations already in the ground are built into customers' rates over decades — if a replacement provider ever came in, those existing assets would have to be written off through a regulatory process, making any switch extremely costly and slow.
What limits this company?
The three state regulators each run their own approval schedules and use different rules for deciding which costs customers must pay for. Infrastructure that Eversource has already built and is already running in one state may not yet have an approved cost-recovery entry in the neighboring state whose grid that same infrastructure supports. Until each commission finishes its own process, the money spent sits in limbo.
What does this company depend on?
Eversource cannot operate without ISO New England, which controls the wholesale electricity market that supplies the power Eversource then delivers. It also relies on approved rate cases from Massachusetts DPU, Connecticut PURA, and New Hampshire PUC to recover the cost of its infrastructure. And it depends on cross-border transmission lines owned by other New England utilities to physically move power across the region.
Who depends on this company?
Massachusetts municipalities rely on Eversource for the backup power that keeps hospitals and police stations running during emergencies. Connecticut manufacturing facilities depend on steady voltage — fluctuations would damage precision equipment. New Hampshire ski resorts need continuous power in winter to run snowmaking systems and ski lifts. Regional data centers supporting Northeast financial services require power that never goes out.
How does this company scale?
Eversource can roll out new substations and feeder lines across similar suburban areas in all three states using standardized designs, which keeps that part of growth repeatable and relatively predictable. What does not scale the same way is managing three separate state regulators, each with its own procedures, timelines, and political environment — that relationship work cannot be templated or handed off.
What external forces can significantly affect this company?
FERC, the federal regulator, can impose regional transmission planning requirements that sit above what any single state commission controls. Massachusetts, Connecticut, and New Hampshire each have their own renewable energy targets with different deadlines, creating uneven compliance pressure across the same physical grid. Stronger Atlantic hurricanes are increasing the demands on coastal transmission infrastructure, raising the cost of keeping the system reliable.
Where is this company structurally vulnerable?
If Massachusetts DPU, Connecticut PURA, or New Hampshire PUC rejected or significantly delayed a rate case, the money Eversource had already committed to cross-border infrastructure would be stranded. The physical grid does not stop at the state line, the equipment cannot be moved, and Eversource cannot walk away from its obligation to serve customers in the non-approving state.
