These flexibility needs are rapidly expanding as a result of numerous industry trends: (a) recognition by policymakers that renewable energy resources are needed to meet long - term
emissions reductions goals; (b) customers» increasing desire to voluntarily procure renewable energy or generate electricity on - site; and (c) substantial technological improvements that have driven down the cost of renewable resources to the point where, even
before accounting for tax incentives, they are the lowest - cost option for new generating
plants in some regions of the country.
Technology currently exists to capture CO2
emissions from coal - fired
plants before they are released into the environment and to sequester that CO2 in underground geologic formations.

Geologic carbon sequestration involves capturing the exhaust gases from power
plants before they are released into the atmosphere, and separating the carbon dioxide from the rest of the
emissions.
Faced with concerns over how quickly new nuclear will progress through the planning and licensing system, and the possibility that even coal
plants that are compliant with existing EU environmental regulation may be forced to close early by the proposed Industrial
Emissions Directive, generators have little choice but to prepare to build a second wave of gas - fired
plants (ie in addition to the 8GW currently under construction) to keep the lights on
before new nuclear and some CCS coal
plants start to come onto the system in the 2020s.
Ideally, given their carbon

emissions from power
plants and other point sources
before compressing, transporting and injecting it deep into the earth.
