Altus prints 10 MWh of batteries on a nearly 200 MW solar buy from Arevon - Marathon prints 10 MW, PV Tech prints 34 states, the release prints 33 plus Washington, and no price is on the pages
On 10 November 2026 Altus Power said its operating portfolio reached 1.7 GW across 33 states and Washington, D.C., after buying 92 projects in 13 states from Arevon: nearly 200 MW of solar and 10 MWh of batteries. Marathon Capital the same day prints 10 MW of battery storage. PV Tech on 12 November prints 10 MWh and 34 US states. No page prints a dollar price or a site list. Taking the round 200 MW, 10 MWh divided by 200 MW is 0.05 hours, our arithmetic, 3 minutes at full output.
A business that buys power from a commercial solar fleet can read three pages about one purchase. Two of them disagree on the battery's unit. None of them prints a price.
Altus Power's Business Wire release, filed 10 November 2026, says the operating portfolio of solar and battery storage reached 1.7 GW across 33 states and Washington, D.C. The growth is the purchase of 92 projects in 13 states from Arevon, adding nearly 200 MW of solar and 10 MWh of battery storage. A megawatt is how hard the panels can push. A megawatt-hour is how much energy a battery holds, like water in a tank. The release does not print an exact megawatt figure inside "nearly 200". It does not list the 92 sites. It names four states where the purchase adds density: New York, New Jersey, Massachusetts and California.
The fleet on that page mixes ground-mounted, rooftop and carport solar with battery storage. It serves commercial and industrial businesses, municipalities, schools, universities and community solar subscribers. The company serves more than 40,000 community solar subscribers. Those subscribers do not own the panels, and the release does not say a subscriber receives a battery. The 1.7 GW is one power figure for solar and batteries together. The release does not split it. 10 MWh cannot be subtracted from 1.7 GW. The units are different.
The purchase was financed in part through an existing credit facility with Blackstone Credit & Insurance. The release prints no dollar size for that facility and no purchase price. Marathon Capital's page, dated 10 November 2026, says it was the exclusive financial advisor to Arevon. It prints the same 92 projects, 13 states, nearly 200 MW of solar, and the same four states. On the battery it prints 10 MW, not 10 MWh. A megawatt is a tap. A megawatt-hour is the tank. The advisor page writes a tap size. The company release writes a tank size. This note does not convert one into the other.
PV Tech, dated 12 November 2026, prints 10 MWh and 34 US states for the same 1.7 GW portfolio, with nearly 200 MW, 92 projects and 13 states, and more than 40,000 community solar subscribers. It says the purchase was part-financed by an existing credit facility from Blackstone. It does not print Blackstone Credit & Insurance, and it does not print Washington, D.C. The release prints 33 states and Washington, D.C. 33 plus 1 is 34, our arithmetic. The release does not print 34, and it does not call the District a state. PV Tech prints 34 US states and does not show that addition. This note does not treat the two sentences as the same sentence.
Taking the round figure the pages print, 200 MW, 10 MWh divided by 200 MW is 0.05 hours, our arithmetic. 0.05 hours is 3 minutes. That is how long a 10 MWh tank would cover if 200 MW ran flat out, and only if the battery figure really is 10 MWh. The pages say nearly 200 MW, not 200 exactly. The 3 minutes uses 200. If the figure a buyer keeps is Marathon's 10 MW, there is no hour count at all.
No page here prints a dollar price, a cent rate, a contract term or a workplace meter. The PV Tech page is a round-up. It also describes a Terra-Gen solar-and-storage project and a Duke Energy Florida solar filing. Those items are not the Arevon purchase. Their dollars stay off this note.
Analogy: nearly 200 MW of panels is a wide tap. 10 MWh, if that unit holds, is a small tank under it, about 3 minutes of full flow on the round 200, our arithmetic. The tank holds only what the panels or the grid put in. Marathon's page writes 10 MW, which is another tap, not a tank. Until the pages share a unit, there is no tank size to put on a workplace quote.
Good: Three dated pages, 10 MWh kept on the Altus and PV Tech lines, 10 MW kept on the Marathon line, 33 states plus Washington, D.C. kept on the release, and 34 US states kept on PV Tech.
Bad: No dollar price, no site list, no exact megawatt inside "nearly 200", no split of the 1.7 GW, no subscriber rate. 0.05 hours, 3 minutes and 33 plus 1 are our arithmetic. The pages do not print them.
Ugly: Adding 10 MWh to 1.7 GW. Reading 10 MW as 10 MWh, or the reverse. Calling 3 minutes an Altus figure. Treating 34 states and "33 states and Washington, D.C." as one printed sentence. Pasting Terra-Gen or Duke figures from the PV Tech round-up onto this purchase. Handing a community-solar subscriber the 92 projects as their own roof.
Soft next step: write 10 MWh on the company release, write 10 MW on the advisor page, and leave the price blank.

Primary for 1.7 GW across 33 states and Washington, D.C., 92 projects in 13 states, nearly 200 MW of solar, 10 MWh of battery storage, density in New York, New Jersey, Massachusetts and California, ground-mounted, rooftop and carport solar, more than 40,000 community solar subscribers, and financing in part through an existing credit facility with Blackstone Credit & Insurance. No dollar price. Marathon Capital, 10 Nov 2026, advisor note. Primary for the 10 November date on that page, the same 92 projects, 13 states and nearly 200 MW of solar, and for 10 MW of battery storage rather than 10 MWh. No dollar price and no 1.7 GW line. PV Tech, 12 Nov 2026, US round-up. Primary for the 12 November date, 10 MWh, 34 US states, and a Blackstone credit facility without the "Credit & Insurance" name. 10 divided by 200, and 33 plus 1, are our arithmetic. The pages do not print 0.05 hours, 3 minutes or 34 as a sum. Terra-Gen and Duke figures on that round-up are not this purchase.
