The integration of variable renewable energy sources (VRES) is one of the biggest challenges facing the energy industry.
VRES are bringing necessary and disruptive change to the global energy landscape at an accelerating pace. Driven by technological advances, policy frameworks and decreasing costs, VRES have created unprecedented opportunities to rethink the way our energy systems operate. But as the energy systems of the future is becoming ever more electricity-intensive, the stability of the grid and the availability of electricity are becoming critical.
The integration of VRES has traditionally represented challenges as well as additional costs for utilities and grid operators. Increasing deployment of variable resources puts strains on the power grid, including the need for energy storage and back-up generation, to meet requirements for both grid stability and security of energy availability.
The large-scale roll-out of VRES requires new solutions for multi-technology system integration.
Key characteristics of the future energy system
Our energy system is becoming more electricity intensive
- A stable grid that ensures availability of electricity are becoming critical for modern day societies
The decentralisation trend continues
- The number of small-scale producers is accelerating, but centralised production will remain important
- New types of stakeholders, such as energy communities and prosumers, are entering the energy markets
- The business environment is changing due to market liberalisation
- There is an increasing role for Information and Communications Technology (ICT) and an overall need for digital services in the energy systems
The push for decarbonisation is accelerating
- New ways for allocating costs to CO2 emissions will evolve
- Pressure to find new incentives for carbon free or positive production
