QUESTIONS ABOUT THE FUTURE – LET’S ASK THOSE WHO HAVE TO LIVE IN IT.

SHOULD ENERGY GENERATION ADAPT TO DEMAND OR DEMAND ADAPT TO SUPPLY?

We engineers like theories, charts and bullet points. But, the issues involved in the energy transition have real consequences. So we turned to the only people big enough to ask the tough questions that force us to act.

Kids.

They’re our reminder of why we all need to keep pushing forward – even if we don’t have all the answers.

Let’s talk!

Together we face a series of big dilemmas. Not just as an industry, but as a planet. Do we fix things now, or wait until the technology is perfect? Do we just accept that energy prices go up when the world goes green? Is occasionally having no energy a good enough reason not to switch to renewables?

This is a world with no clear answers. As engineers, business people, and as parents we have a duty to start taking the questions away, one by one. That’s where Wärtsilä’s balancing technology comes in.

Current market trends show the energy landscape is transitioning towards more flexible energy systems with a rapidly increasing share of renewable energy, a declining inflexible baseload generation, and a wider application of storage technology.

The declining costs of renewables have begun to reduce new investments into coal and other inflexible baseload technologies; a transition that will eventually cause renewables to become the new baseload.

Wärtsilä aims to accelerate this transition towards a 100% renewable energy future. We have the experience to maximise the transition for our customers by analysing customer requirements and building optimal energy systems with lowest total cost of ownership.

BALANCING POWER The bridge to the futureAs intermittent renewables increasingly displace traditional baseload generation the greater the need becomes to shore up the grid’s stability with balancing capacity (see the graphs hereby illustrating this).

Energy producers need to invest in flexible technologies that provide fast-ramping balancing power that can be scaled up as the share of renewables in the power system increases. Wärtsilä’s flexible and scalable balancing solutions quickly ramp up whenever renewables aren’t generating enough electricity – providing the necessary balancing power to keep the grid stable, with energy storage solutions for shorter hour-level firming and dispatchable gas engines for unlimited periods of firming. Because it protects operators and grids from the peaks and dips of renewable energy, balancing technology makes it easier for them to decarbonise – without jeopardising stability, while still meeting their customers’, partners’, and shareholders’ needs.

BALANCING POWER The bridge to the future Hope for the best or rely on the data? Thanks to our years of experience in

global energy systems, Wärtsilä can accurately model the optimal path to 100% renewables – for any country or customer. The data shows just how important the role of balancing solutions will be in making the transition as affordable and reliable as possible – all the while slashing greenhouse gas emissions and air pollution, and alleviating land-use and grid construction pressures.

There’s no one path towards a renewable energy future – it varies by location. For many energy operators, the optimal route involves a flexible power system combining renewable energy sources, gas engines, and energy storage solutions. While the details vary, the goal is always the same: to minimise emissions of CO2, NOX, and particulates, maximise the use of renewables, and choose the most profitable and cost-efficient solution.

Our power system modelling results showcase an example of an optimised energy transition scenario with the help of balancing technologies.

Wärtsilä’s future-proof balancing portfolioWärtsilä’s balancing portfolio is not a single solution or a product, but a full solution portfolio.

We focus on understanding the customers and their path towards optimised renewable generation in their specific locations. In order to calculate the most cost-efficient and reliable route towards 100% renewables, we rely on advanced modelling capabilities based on proven data sources.

Flexible• Our balancing power plants can

be adapted to different operation profiles and running hours, so you can integrate renewables seamlessly into your energy mix as they come on-stream.

• Today, our plants can already run on biogas and hydrogen blends. Our fuel-pioneering R&D is continuously working on adapting solutions to future fuel alternatives.

Profitable• With outstanding efficiency, fast

start-up times and a wide load range, our balancing solutions are well poised to maximise the revenue stack in a dynamic balancing market.

• Lower investment costs thanks to high power density and optimised plant designed for balancing.

• Remote monitoring and control require fewer people on the ground.

Reliable• We’ve delivered over 74 GW power

plant capacity in 180 countries – we know when a technology works. This technology has clocked over 43 million hours of run time with up to 99% year-round reliability in the plants we operate.

• We provide 24/7 support from our Expertise Centres to customers with Wärtsilä Lifecycle solutions.

The core aim of our work is to create a future-proof energy system where the use of renewable energy can be maximised and the solutions formulate an entity that is greater than the sum of their parts. We test how engines and storage systems communicate, develop

ramp up capabilities and optimise dispatching with advanced energy management systems.

Our balancing engines will be able to run on any future fuels, no matter which fuel type is the dominate one. Already today, they can use natural gas, biogas, synthetic methane or hydrogen blends. We’re also actively researching hydrogen and other future fuels to eventually enable a fully decarbonised power system which still has a security of supply from flexible, dispatchable gas engines generating electricity when required.
