Electricity can not be stored.

It has to be made

right when you use it



Energy can be storedAnd made into electricity when you need it



Some types of generation can’t always be used

when you need them

Transient generation needs a dispatchable

partner to enable a reliable grid



There are Lots of Partnering Technology Options

Batteries and Pumped Storage Dispatchable Natural Gas

Siemens Co-Start™ Technology

Fast Bottoming Cycle Start Up

Co-Start means lots of power fast

Co-Start uses an integrated hardware and control package which enables

the steam turbine to ramp up early and quickly, while protecting

equipment for reliable operation over the life of the plant.

• No low load gas turbine hold

points

• Fast Ramp of the steam

turbine

• Base load power in about 30

minutes



Co-Start results in an

Estimated Savings over

$25,000,000 NPV

Flex-Plants with Co-Start Offers Significant Savings to the Bottom Line

Reducing Operating Costs

Saving Money with Co-Start
