Puget Sound Energy customer saves $320 annually by charging EV overnight on time of use tariff
By Eve
A Puget Sound Energy customer driving 1,100 electric miles per month reported annual savings of around $320 by charging exclusively during overnight off-peak hours at 12 cents per kilowatt-hour, avoiding weekday peak windows of 7 to 10 a.m. and 5 to 8 p.m. when rates reach 32 cents in summer and 55 cents in winter. The household shared month by month bill comparisons on Reddit demonstrating the savings under the utility's time of use plan versus standard rates, even with central air conditioning use.
Why it matters
The case illustrates how time of use tariffs can deliver measurable cost savings for EV drivers willing to shift charging behaviour, a model that could inform tariff design and customer engagement strategies for charge point operators and utilities seeking to manage grid demand and improve the economics of home charging.

Puget Sound Energy installs pole-mounted charger and fleet unit in Redmond partnership
Puget Sound Energy has installed a dual pole-mounted public charging station at 17725 NE 65th Street near Marymoor Park in Redmond, allowing two vehicles to charge simultaneously at no cost to the city. PSE also deployed a fleet charger for Redmond Fire Department's new electric fire engine and future electric vehicles. The utility is working with the city to identify the next charging location as part of its broader push to expand transportation electrification access with municipal partners.
Why it matters
The dual charger pole-mounted model and free installation demonstrate a utility-led approach to lowering municipal barriers for public charging rollout. PSE's combined public and fleet deployment strategy with Redmond signals a replicable partnership framework for cities seeking to electrify both community access and municipal fleets.
Massachusetts advances 700 MW Trimount battery near Boston, the largest storage project in New England
Massachusetts is progressing the 700 MW Trimount battery project just outside Boston, according to The Cool Down, citing Canary Media. A 200 MW facility near the Rhode Island border is already under construction, and another developer in a neighbouring town has secured $850 million for a 250 MW project. The state targets 5 GW of storage online by 2030 and a further 5 GW by 2035, against California's 23 GW of installed capacity.
Why it matters
Large batteries that charge when power is cheaper and discharge at peak could ease grid constraints and soften peak pricing in a state with some of the highest electricity prices in the US. For CPOs and charging developers in Massachusetts, a growing storage pipeline and an aggressive procurement policy signal where grid capacity and pricing dynamics may shift.
Up to 48 million US homes may need electrical upgrades as smart panels offer a possible alternative
Up to 48 million US households could require electrical upgrades as residents adopt electric cars, stoves and water heaters, according to a report from The Cool Down citing an EcoBits YouTube video hosted by Justin Pack. The video's caption put the potential cost of those upgrades at $100 billion, though it did not say how much an individual homeowner could save with a smart panel. Smart panels monitor household electricity use and adjust loads automatically before a breaker trips, with older homes flagged as a particular concern.
Why it matters
Home electrical capacity is a potential barrier to residential charger installs, and load managing panels could cut the need for costly service upgrades. Installers and CPOs offering home charging should note the cost figures are an estimate from a video caption and individual savings were not stated.
