Illinois Tests Base Power Portability
Base Power
Illinois is the first real test of whether Base is a Texas specific pricing trick or a repeatable energy platform. In ERCOT, the model works because one company can bundle the battery, the retail power contract, and battery dispatch into a fast moving 15 minute market. Illinois keeps the retail choice piece, but PJM adds DER aggregation rules and more interconnection process, so any drop in payback will show exactly which revenue layer matters most.

ERCOT gives Base unusually clean economics. It runs a competitive retail market with more than 8 million premises in choice areas, settles real time prices every 15 minutes, and lets distributed generation reduce a retail provider's settled load. That makes retail margin and battery arbitrage fit together naturally.

Illinois preserves only part of that setup. Residential customers in major utility territories can choose an Alternative Retail Electric Supplier, but wholesale participation sits inside PJM's Order 2222 style DER aggregation framework, where behind the meter batteries must be aggregated and cleared through more formal market rules.
-
That is why Illinois matters beyond one state. If Base can still get close to its roughly 3.5 year battery payback after losing ERCOT's simpler market structure, the company has a path into a much larger eastern footprint. If not, expansion starts to look more like a utility services business than a scaled gentailer.
The next phase is less about selling backup power and more about proving the revenue stack can survive market by market rewiring. A successful Illinois launch would show Base can transplant its operating playbook into PJM and then MISO, which would turn Texas from the whole story into the first template.
