Energy Storage Systems for the Home

July 12, 2025

Hi Reader,

This week’s newsletter topic is Energy Storage Systems for the Home.

Two factors — rising utility costs and unreliability — are driving homeowners to pursue ways to mitigate these untenable trends, which are a result of growing energy demand, aging infrastructure, extreme weather events, and operational incompetence.

Making matters more challenging are four concurrent residential energy-related shifts that require 24/7 reliability:

  • An aging population relying on critical medical devices
  • Extended outages during periods of life-threatening temperatures
  • Remote workers requiring “always on” electricity and connectivity
  • Households with increasing energy demands, such as electric vehicle charging stations

Homeowners who are familiar with inept local power planning commissions, or who have experienced feckless disaster preparedness and responsiveness, are aggressively adopting backup power storage solutions — think California, Texas, Florida and North Carolina.

Customers of new solar systems are also fueling storage adoption rates:

  • Currently 28% of new U.S. residential solar installations include energy storage, referred to as solar-plus (Source: SEIA)
  • National attachment rate of battery storage to new residential solar installations grew from 6% in Q1 2020 to 25% in Q1 2024, with 60% of new solar installations in California (Source: Wood Mackenzie)
  • By 2032, storage batteries for new solar systems could exceed 50-60%, driven by cost declines, policy incentives, and increasing demand for resilience

Assuredly, the adoption of energy resilience solutions among growing numbers of homeowners will serve as a lead, gateway to “privatization” that is part of a growing movement in the U.S. toward utilizing independent services. These are services traditionally managed by public institutions, such as: utilities (water and power); public safety (fire and police) and other services commonly funded by property tax dollars (education).

We leave you with a reminder of the present, mixed with a taste of the future:
