Solutions to Power the Grid

Make your transition to 100% renewable energy profitable – while also ensuring reliable operations

The energy market landscape is in transition and is moving towards more flexible energy systems with a rapidly increasing share of renewable energy, declining inflexible baseload generation, and wider applications of storage technology. Tightening emissions legislation is forcing the closure of ageing capacity, with carbon-intensive energy sources being replaced by low carbon fuels, such as natural gas and renewable source solutions.

As an energy system integrator, we understand, design, build and serve the optimal power system designed for your business use cases.

Utilities understand


Rapid cost reduction of intermittent renewable energy are changing the power system planning criteria for most utilities globally. With advanced techno-commercial power system modelling tools we can look for optimum capacity mix during this transition. Power system modelling gives the optimum capacity mix via dispatch modelling considering different possible future scenarios. 

Our highly experienced power system modelling team has modelled over 50 countries and power systems globally with PLEXOS power system optimisation software.

Design & build 

We offer Engineering, Procurement and Construction capability for all our solutions. Our engine power plants act as a stepping stone for the transition today and provide flexibility in all phases of the path towards 100% renewable energy systems.  Wärtsilä power plants, based on internal combustion engine units, are a perfect fit for baseload generation, balancing and enabling the integration of wind and solar power ensuring reliable and profitable power generation that reduces your environmental impact. 

You can prepare for risks in present and future markets with the best combination of fuel flexibility, operational flexibility and energy efficiency offered by our Smart Power Generation technology.
Utilities design and build

Fuel flexibility 

  • Operation in any gaseous or liquid fuels, including biofuels
  • Improved fuel security by continuous choice of the most feasible fuel

Operational flexibility 

  • Fast start to full load in less than 5 minutes regardless of plant size
  • Unlimited starting and stopping with no impact on maintenance

Energy efficiency

  • High baseload efficiency, regardless on ambient conditions
  • High plant efficiency over a wide load range due to the modular internal combustion engine design

Energy Storage

Greensmith Energy, a Wärtsilä company, offers unrivaled global capabilities for energy storage and integration. Our solutions strengthen the reliability and flexibility of the grid, integrate more renewable power into the system and optimise multiple generation assets to build a resilient, intelligent and flexible energy infrastructure.

Utilities operate and maintain

Operate & maintain

Ensuring reliable and cost efficient energy production is key. With our lifecycle solutions for power plant operation and maintenance, you get guaranteed operational reliability and efficiency, backed up by expert advice on optimising the operation and maintenance of your power system. Performance targets are agreed upon on measured data. The performance of your installations during the lifecycle can be optimised for example through upgrades, modernisations and fuel conversions. By partnering with us, you can feel secured and focus on your core business.
