Corporate Sourcing of Renewables Campaign

Wind and solar power are seeing a rapid increase in many Clean Energy Ministerial (CEM) countries. Accommodating the growing shares of wind and solar power poses novel challenges for power systems, because their output fluctuates with the climate and weather. Dispatchable power plants — including thermal generation — are key to providing the system flexibility needed to deal with the fluctuating balance between supply and demand of electricity.

The Goal

To build strong momentum and commitment from governments and industry to implement solutions that make power generation more flexible.


The Opportunity

Government, utilities, manufacturers, equipment suppliers, international organizations, the research community, and other private and public sector stakeholders can accelerate the achievement of this goal in many ways. For example:

  • Leverage international experience to enhance the impact of domestic policies and actions. 
  • Improve the flexibility of current assets and determine opportunities for cost-effective operational improvements.
  • Share and exchange best practices for comprehensive assessments of generation fleets.
  • Identify key innovative technologies that can improve utilities’ bottom line.
  • Share insight and experience on the various technical solutions that can be deployed to improve power plant flexibility.
  • Raise awareness among a broader audience about efforts to improve power plant flexibility.
  • Assess which research activities should be prioritized.
  • Analyze the system benefits of increased supply-side flexibility.

The Advanced Power Plant Flexibility Campaign builds from work taking place in CEM’s Multilateral Solar and Wind Working Group and 21st Century Power Partnership.

Why It's Needed

To integrate variable renewable energy. Variable renewable energy (VRE) — such as wind and solar power — technologies differ from traditional power generation sources. Most important, their output fluctuates over time, driven by the varying availability of wind and sunlight. The growth of VRE capacity thus calls for increased system flexibility. Flexible dispatchable power plants are a main source of flexibility in power systems, alongside grids, demand shaping, and storage.

To highlight today’s success. Many countries are demonstrating that a flexible power supply can successfully deal with fluctuations in supply and demand. Power plants that were built to run around the clock are undergoing retrofits and seek new sources of revenue to encourage more dynamic operations.

To unlock the flexibility potential. In many power systems, regulations, market design, and contractual arrangements may encourage an inflexible operation of power plants. As a result, there is a tremendous amount of supply flexibility that is available from a technical perspective, but not exploited in reality. 

To optimize the utilization of generation assets. A better understanding of the capabilities that are needed in the power system of the future can foster a better use of existing power generation assets. This will also lead to a heightened awareness of the complementarity of flexible generation sources and variable renewables, and demonstrate that they align in the collective effort to safeguard a cleaner, cost-competitive, and reliable power system.


The Campaign will recognize high-level commitments to help increase power plant flexibility:

  • At the eighth Clean Energy Ministerial (CEM8) meeting in Beijing, China, on 6–9 June 2017.
  • At other high-profile events over the coming year.
  • At the ninth Clean Energy Ministerial (CEM9) meeting in Europe in 2018.

The Coalition

The governments of China, Denmark and Germany lead the campaign; participating countries are Brazil, Canada, India, Indonesia, Japan, Mexico, Saudi Arabia, South Africa, United Arab Emirates and the European Commission. Companies participating in the campaign include Enel,, General Electric, DONG energy and COWI; the German think tank Agora Energiewende is also a member. The International Energy Agency (IEA) supports the implementation of the campaign as operating agent. Participants have each made specific commitments on how to advance the objectives of the campaign; see below.
