Exelon sketches $3 billion to $7 billion for 1.5 GW to 3.5 GW of utility-owned batteries - the New Jersey box is 500 MW and four hours, the call prints no build cost, and a questioner said $2 billion
On 30 October 2026 Exelon told investors it sees 1.5 to 3.5 GW, about $3 billion to $7 billion, of regulated storage beyond the capital plan. The 500 MW Atlantic City Electric project, with Invenergy, is expected to deliver more than $700 million in net benefits, with no bill impact in the first five years. A New Jersey order of 9 September calls it up to 500 MW and four hours, on utility land in Pittsgrove, and records a 4 September letter that found the petition administratively deficient. Utility Dive on 2 November prints a $1 billion cost the call does not. No solar plant is named on the site. The battery is not on a customer's premises.
A business that buys power from Atlantic City Electric does not own this battery. The utility wants to own it, and to recover it later on the bill. The first five years are printed as a pause on that impact. The box stores energy. It does not make it.
On 30 October 2026 Exelon held its third-quarter earnings call. Chief financial officer Robert Kleczynski said the company currently sees 1.5 to 3.5 gigawatts, or approximately $3 billion to $7 billion, of potential regulated storage investment beyond the capital plan. He said customers benefit through lower capacity prices and the flow-through of tax benefits, which smooth rate impacts. He did not print a tax-credit percentage. He said New Jersey, Maryland and Delaware allow utility ownership of storage as a resiliency asset. He called the 500-megawatt Atlantic City Electric project, developed with Invenergy, the example: the single largest battery storage installation in PJM, expected to deliver more than $700 million in net benefits to customers. He said the New Jersey Board of Public Utilities is moving forward with its review, and that Exelon expects a final order late in the first quarter of 2027.
Chief executive Calvin Butler, on the same call, put the same range beside the transmission opportunity: $12 billion to $17 billion of transmission, and another $3 billion to $7 billion of potential regulated storage, both beyond the plan. He described the proposed 500-megawatt project in New Jersey as more than $700 million in expected net customer benefits, with no customer bill impact during its first five years of operation. A questioner on the transcript, Shahriar Pourreza, described the storage figure as $2 billion to $7 billion. The prepared remarks say $3 billion. The transcript's own summary bullet prints $700 million for the New Jersey benefits. The spoken line is more than $700 million.
Two clocks on the build. Chief operating officer Carim Khouzami said that once the New Jersey project has approval, the company expects it up and running in just under three years, and that is when it goes into rate base. He also said large batteries are being pursued under build-own-transfer arrangements, with much of the capital near the end of construction. The prepared remarks treat the New Jersey project as the utility-owned example. The build-own-transfer line is a second structure on the same call. This note does not fold one into the other. Khouzami said the 1.5 to 3.5 GW pipeline sits across all of the company's states, with a large portion in Maryland, Delaware and New Jersey, where the utility can own storage today. He did not print a megawatt split.
The order, which is older than the call and is the page that describes the hardware. On 9 September 2026 the New Jersey Board of Public Utilities issued an order in docket EO26070402. Atlantic City Electric filed the petition on 23 July 2026. With the company's consent, the effective filing date is 8 August 2026. The order says the project is a battery of up to 500 megawatts with a four-hour duration, on company-owned property in Pittsgrove Township, Salem County, using lithium iron phosphate batteries. Five hundred megawatts for four hours is 2,000 megawatt-hours, by our arithmetic. The order does not print 2,000. It says the company estimates about 36 months to complete, and commercial operation in late 2030, subject to interconnection. A first-quarter 2027 order plus 36 months lands in the first quarter of 2030. The order prints late 2030. Both clocks are on the record.
Who pays, on the order. The company proposes to put the project in rate base and recover capital costs and operations and maintenance through a monthly surcharge. It says customers would not see bill impacts tied to project costs for five years after commercial operation. That matches Butler's five-year line. The order cites a benefit-cost analysis by a company witness, Giovannini, at $1.36 in benefits for every $1.00 invested. That ratio is not the call's $700 million, and dividing one by the other is not a cost this note will print. The project would sell energy, capacity and ancillary services into PJM. Energy it sells is energy it stored first. Capacity and ancillary services are payments for availability and for grid support. The order does not name a solar plant on the site. It says the petition cites the governor's order identifying solar generation and battery storage as resources. Naming solar in a policy sentence is not a panel count.
The filing status the call does not mention. The 9 September order says Board staff, on 4 September 2026, found the petition administratively deficient. The order keeps the matter for a hearing once the company submits a version staff calls administratively complete, and it designates a presiding commissioner. The 30 October call says the review is moving and points to a final order late in the first quarter of 2027. A reader of the call alone does not see the September letter.
The $1 billion and the $8 billion. Utility Dive, published 2 November 2026, reports the 30 October call and prints the New Jersey project as $1 billion and 500 MW, not included in the $3 billion to $7 billion range. Its headline figure is $8 billion. Seven plus one is eight, by our arithmetic, and that sum uses the $1 billion. The earnings-call transcript does not print a dollar cost for the 500 MW project. The September order does not print one either. Atlantic City Electric serves approximately 576,000 customers in southern New Jersey, the order says. The petition, as the order summarises it, cites an approximately 17 percent increase, or approximately $28 a month, in customer bills in the summer of 2025. That is the petition's picture of an earlier bill movement. It is not a surcharge for this battery.
A different utility plan already on this desk, Dominion's multi-year battery sketch, is another company's filing. Exelon's range is a new page. Neither page is a quote for a battery on a factory wall.
Analogy: the utility owns the tank. A customer owns the bill, later. Five years is the pause printed on the impact. $700 million and $1.36 are expected benefits, not a line on an invoice. $1 billion is a trade page. $8 billion is that page's addition. The tank holds a charge. It does not make the charge.
Good: A call date, a named utility, a gigawatt range with a dollar range, a named 500 MW project, a four-hour label on the order, a five-year bill line, and a public docket that records the deficiency.
Bad: No build cost on the call or the order. $1 billion and $8 billion are Utility Dive. $2 billion is a question. $700 million and $1.36 are expectations, in different units. 2,000 MWh is our multiplication. Just under three years, 36 months, and late 2030 are three clocks. The call omits the deficiency. No solar plant. No cents. No surcharge dollars.
Ugly: Treating $8 billion as a figure Exelon spoke. Treating $1 billion as the order's cost. Treating $700 million or $1.36 as cash on a bill. Treating the five-year pause as a permanent exemption. Putting this battery on a customer's premises. Reading the box as a power plant that runs with nothing stored in it. Reading the summer 2025 bill line as this project's charge.
Soft next step: keep $3 billion to $7 billion on the range, keep four hours on the order, and leave the New Jersey build cost blank.

Primary for Kleczynski's 1.5 to 3.5 GW and approximately $3 billion to $7 billion beyond the plan, the flow-through of tax benefits with no percentage printed, utility ownership in New Jersey, Maryland and Delaware, the 500 MW Atlantic City Electric project developed with Invenergy, more than $700 million in net benefits, a final order expected late in the first quarter of 2027, Butler's matching dollar range and the line of no customer bill impact in the first five years, Pourreza's "$2 billion to $7 billion", the summary bullet that prints $700 million rather than more than $700 million, Khouzami's "just under three years" after approval and the separate build-own-transfer remark, and the statement that a large portion of the pipeline is in the three states where the utility can own storage. The transcript does not print a dollar cost for the 500 MW project, a megawatt-hour figure, a four-hour label, or the September deficiency. New Jersey Board of Public Utilities order, docket EO26070402, 9 September 2026. Primary for the 23 July petition, the 8 August effective filing date, up to 500 MW and four hours, Pittsgrove Township in Salem County, lithium iron phosphate batteries, about 36 months and late 2030 subject to interconnection, Invenergy as operations and maintenance manager once the plant is in operation, five years with no bill impacts from project costs, the Giovannini benefit-cost figure of $1.36 per $1.00, sales of energy, capacity and ancillary services into PJM, rate-base recovery through a monthly surcharge, approximately 576,000 Atlantic City Electric customers, the petition's approximately 17 percent or approximately $28 a month summer 2025 bill figure, the 4 September staff letter finding the petition administratively deficient, and the decision to keep the matter for a hearing once a complete filing is in. The order does not print 2,000 MWh, a project dollar cost, or a solar megawatt figure. 500 times 4 equals 2,000: that product is our arithmetic. A first-quarter 2027 order plus 36 months is our calendar arithmetic, and it is not the order's "late 2030". Utility Dive, Ethan Howland, 2 November 2026. Primary for the $1 billion cost printed on the 500 MW New Jersey project and for the $8 billion headline. Seven plus one equals eight: that sum is our arithmetic, and it uses Utility Dive's $1 billion. The call and the order do not print either dollar total.
