Distributed Generation Development

• HB 10-1001:– Absolute 3% DG requirement in 2020 (contrast to 4%

solar calculation)– Defines DG as a renewable resource not requiring any

additional substation or transmission facilities:o Retail – interconnected on the customer side of the

meter (may not supply more than 120% of customer’s average annual consumption)

o Wholesale – interconnected directly to distribution at normal distribution voltages (nameplate rating must be 30 MW or less)

• Goals: – Meet reasonably foreseeable requirements of federal

Clean Air Act– Protect public health and the environment at a lower

cost than a piecemeal approach

Clean Air – Clean Jobs: HB10-1365

• Means: Retrofit, Retire, Replace

• Preferred replacement: – natural gas– Long term natural gas contracts are encouraged

• Public Service expected to address at least 900 MW of generation in the Front Range of Colorado

Clean Air – Clean Jobs: HB10-1365

• Key Dates:– August 15, 2010: Public Service plan due– December 15, 2010: PUC decision due– Early 2011: Legislative approval– December 31, 2017: Plan to be fully implemented
