Context: High Stakes U.S. power industry is entering a build cycle with much higher investment levels Brattle: $2T by 2030 (~2x recent levels) Causes Aging infrastructure New transmission requirements Demand side and smart grid Air and water regulation much stronger Fuel economics Challenges to utilities Flat load growth Distributed generation Uncertain economy Financial metrics less forgiving than 1980s 4
Brattle s Investment Projection 5
Notes Unadjusted 2010 cost estimates were used for consistency Costs for wind and photovoltaics have fallen sharply in last two years (faster than these 2010 estimates) Cost of nuclear power has risen post-fukushima (more than these 2010 estimates)
New Power Generation Risks Initial Cost Risk: includes unplanned cost increases, delays and imprudent utility actions Fuel and Operating Cost Risk: includes fuel cost and availability, as well as O&M cost risks New Regulation Risk: includes air and water quality rules, waste disposal, land use, and zoning Carbon Price Risk: includes state or federal limits on greenhouse gas emissions Water Constraint Risk: includes the availability and cost of cooling and process water Capital Shock Risk: includes availability and cost of capital, and risk to firm due to project size Planning Risk: includes risk of inaccurate load forecasts, competitive pressure
