Cal. Pub. Util. Code § 8101

Under certain conditions the sale and distribution of electric power and energy in the same geographical area both by an electrical utility and by an irrigation district, results in duplication of service, waste of materials, increase in costs, waste of manpower and economic loss, and is detrimental to the efficiency and best interests of such districts. It is the policy of this State to induce such utilities and irrigation districts to prevent or remove such economic waste and to adopt more efficient and economic methods of distribution of electric power and energy, and to that end encourage the definition of areas to be served or not to be served by each.
