Illinois as PJM MISO Beachhead

Illinois matters because it is less a new state launch than a test case for whether Base can turn a Texas specific battery and retail power bundle into a repeatable playbook across eastern grid markets. Illinois keeps the retail choice piece intact, but the harder part is proving that hundreds or thousands of home batteries can be grouped, registered, and dispatched through PJM style market rules tightly enough to preserve Base’s fast payback math.1 2 3 4 5

• Base’s Texas model works because one customer relationship produces three money streams at once, battery fees, retail power margin, and grid trading. Illinois preserves the retail supplier role, but PJM and MISO add more coordination layers around DER aggregation, telemetry, and distribution utility signoff than ERCOT does.1 3 4 5
• The Illinois hiring plan points beyond one state. The new regulatory role is scoped to eastern RTOs more generally, which fits the map. PJM spans all or parts of 13 states and D.C., and MISO is building its own DER aggregation path, so operational lessons from Illinois can be reused across a much larger corridor.1 2 4 5
• This is also a competitive filter. Selling batteries alone is easier, SPAN helps manage home loads and Tesla bundles batteries with retail power in some markets, but Base is trying to own the battery, the electricity bill, and the grid dispatch together. If that stack works under PJM and MISO rules, fewer rivals can copy it cleanly.1 6

The next step is a shift from proving product demand to proving regulatory portability. If Base can make Illinois installations behave like a coordinated grid asset while still winning retail customers, it opens a path into a multi state eastern footprint. That would move the company from a strong Texas operator toward a national distributed utility platform.1 2 3 4 5
