Speed matters

Smart Power Generation power plants can start in 30 seconds.

And ramp to full output in less than 5 minutes.

MATCHING DEMAND AND SUPPLY

To keep the lights on in today’s power systems, flexible generation is imperative. Agile capacity is needed, for example, to shave peaks in electricity demand and to fill gaps of wind and solar output.

    1. OPERATIONAL FLEXIBILITY

    The fast-responding and efficient engines make Smart Power Generation power plants suitable for various tasks:

    • Use for baseload, peaking and load-following generation
    • Back up the intermittent output of wind and solar energy
    2
    2. ENERGY EFFICIENCY

    The modular design of multiple cascading engines makes Smart Power Generation fuel efficient at any load.

    • Get more energy from the same amount of fuel
    • Save money and cut CO2 emissions
    3
    3. FUEL FLEXIBILITY

    Smart Power Generation plants can use any gaseous and liquid fuels, including biofuels. They can even switch from one fuel to another without stopping.

    • Gain fuel security
    • Use the cheapest and the cleanest fuels available

    plants actually exceeds that of turbine-
    based technologies.”

    APPLICATIONS

    In the old days operating the power grid was easy. The load curves were stable and predictable. This is now quickly changing, highlighting the need for fast-reacting capacity.

      CASH IN ON PRICE SPIKES

      The real time prices in SPP are extremely volatile, including sudden sharp spikes. These events are short-lived, but they offer the golden window of opportunity to make money - if you are able to start and ramp up your asset fast enough.

      MAXIMIZING THE VALUE OF FLEXIBILITY

      The newly-enacted reform paves the way for private investment in the power generation secctor, and we at Wärtsilä believe that flexibility is the only way to build the power system of the future while at the same time decreasing the cost of electricity for consumers.

      WHAT HAPPENED TO THE BASELOAD?

      The “Irish Hedgehog” shows the output for thermal power plants if the target of doubling wind capacity is reached. Wind output is subtracted from demand. The baseload disappears and only sharp peaks are left for power plants.

      GRABBING THE DUCK BY THE NECK

      The "Duck Graph" shows what happens to the daily load curve of gas power plants in California with increasing solar PV capacity. On a sunny afternoon the duck’s belly deepens and less electricity is needed from power plants. But at dusk they must soar several GW’s in a very short time. To cope with the duck’s neck, extremely flexible generation is needed.

      CAN YOU TRUST WIND?

      The growth of wind power in the UK increases the need for operating reserve dramatically. Reserves are required to ensure a steady flow of electricity even with high shares of wind capacity. The scenario is for the year 2020.

      SOURCES OF FLEXIBILITY

      In addition to quick-starting generation, there are other means to increase the much-needed flexibility in power grids. Their potential appears to be small in comparison, though.

        BIRD’S-EYE VIEW TO WEATHER FORECAST

        According to electric highway or super grid theory, excess wind and solar energy can be transported from one country to another according to demand. But satellite data shows that weather systems are often continent-wide. When it is windy in Spain, it is often windy in Germany too. This can be an obstacle for super grids.

        NOT QUITE THERE YET

        To handle 2 GWh of the consumption peaks with stored electricity in California would require about 16,000 containerized battery sets – enough to cover 100 soccer fields. After 10 years the batteries would have to be replaced and handled as toxic waste. The example illustrates the scaling issue of energy storage.

        SMALL FIX TO A BIG ISSUE

        Shaving peaks in electricity consumption with smart household appliances and other demand response technologies is said to be one solution for the flexibility challenge. However, these solutions seem to be capable of handling only a fraction of the demand peaks.

        WHO IS THE FASTEST?

        Smart Power Generation plants can ramp to full power 50 per cent faster than traditional turbine solutions, but the real flexibility challenge is ramping up and down continuously. Due to lower temperatures, internal combustion engine plants are capable of doing even a continuous yo-yo movement without impact on maintenance.
