- Method
- Doctrinal and comparative legal analysis. The article examines utility duty-to-serve premises and emerging large-load arrangements, then draws cautiously from federal natural-gas curtailment/capacity-release law and western prior-appropriation/water-market doctrine.
- Finding recorded in corpus
- The authors propose a contracts- and trading-based 'demand-side connect-and-manage' framework under which large loads can connect subject to priority, curtailment, and transfer rules; they contend this could accelerate connections and place more overbuild and innovation risk on large data-center companies.
