Lubbock Power & Light (LP&L) is the city's municipal electric utility: it owns and operates the infrastructure that delivers electricity to every Lubbock home and business. LP&L maintains the poles, wires, transformers, and substations. This infrastructure function is called transmission and distribution, and LP&L handles it regardless of which retail electricity provider you choose.
What changed in 2021 is that Lubbock joined the ERCOT deregulated market for the energy itself. Before deregulation, LP&L also supplied the electricity. Now, you can choose which company sells you the electricity, while LP&L continues to deliver it through its infrastructure. This is the same model that Houston, Dallas, and most of Texas have operated under for years.
In practical terms, this means your monthly bill has two components. The delivery charge is set by LP&L and is identical regardless of which retail provider you use: it covers the infrastructure. The energy charge is set by your chosen retail provider, like Abundance. That is the part you can shop and compare.
When you enroll with Abundance, LP&L remains your physical utility: they still read your meter, respond to outages, and maintain the lines. Abundance handles your billing, your rate, and your customer relationship. If your power goes out, you call LP&L at (806) 775-2509. For everything else (your bill, your plan, your rate), you call Abundance.
