The engine also has a number of modifications to help minimize friction and optimize
fuel economy: there are low - friction bearings for the camshaft and balancer shafts, piston rings that have less pre-tension, and the oil pump is a two - stage device with volumetric
flow regulation.
Each spreadsheet lists the model estimates of capacity additions (what electric generating capacity the model and what the states tell the model to include because of
regulations); generation (how much the existing and projected units will produce); prices (including firm power prices, energy prices, capacity prices, allowance prices, natural gas prices, and renewable energy credit prices); total CO2 emissions;
fuel consumption for different
fuel types; and transmission
flows into and out of the RGGI power grids.
