We are looking for innovative ideas and solutions to make our electricity generation more circular and more sustainable, helping to reduce the consumption of raw materials and minimizing the production of waste for the environment. We propose 3 streams of challenges which will be detailed below:  

  1. Value Recovery
  2. Repair and Improvement
  3. Sharing


Stream 1) Value Recovery

As EGP&TGx, we are recycling around the 60% of waste produced. The zero-waste project is the most important project that collects all the initiatives implemented within EGP&TG.  

The following initiatives, based on circular economy criteria, have already put in place:

  • mineral oil recycling; 
  • the sale of scrap from the demolition of power plants; 
  • the recycling of wind blades; 
  • the sale of spare parts and equipment; 
  • the sale of ashes and gypsum.


Value Recovery stream

The challenge is looking for innovative or alternative solutions with respect to the ones currently in use. The new solutions must:

  • increase the percentage of waste/materials/component recovery (e.g solar panels, batteries, electronics devices, concrete);
  • improve waste collection and diversification, preferably without increasing the effort needed to recover value internally for energy and materials streams.


Stream 2) Repair and Improvement

Repairing components is a well-known practice within Enel, since a lot of equipment is repaired, internally or externally, instead of being replaced. 

Most of the time, the components are repaired ex situ (e.g. hydroturbines or minor and main components of wind turbines) through traditional techniques.



Stream Repair and Improvement

In order to increase and improve our repair approach, EGP&TGx is looking for new innovative solutions or approaches with respect to those already in place that can: 

  • increase the number and type of equipment repaired and/or reduce the consumption of materials used for the repair (e.g use of additive manufacturing, in situ machining, etc.); 

  • decrease repair costs (i.e. through new repair service contracts, equipment rental instead of ownership, etc.); 

  • repair components that are currently not repaired but replaced.

Example: At geothermal power plants, Enel has started to repair impellers of gas extractors and rotors of 20MW and 60 MW turbines through additive manufacturing, which previously couldn't be rehabilitated through conventional processes. 


Stream 3) Sharing

Sharing practice is quite new within the Enel Generation Business Line because assets are often complex plants that must be operated by expert people and cannot therefore be shared with the external public as can be done with cars or laundry sharing services. In spite of this, we can apply forms of sharing to our assets and some countries are trying to use parts of power plants, like auxiliary production systems, to meet the needs of industries in the area, as is done for example in Peru and Chile, where demineralized water production plants are operated to meet the demineralized water needs of industries located close to the power plant. In this way, the plant keeps working during the shutdown period, increasing its operation time and, in a way, it is shared with external stakeholders.  

Other examples include sharing the land of our renewable plants are located on, for example floating photovoltaic plants where PV panels are laid on the water basin of a hydroelectric dam or agri-photovoltaics, where a PV power plant’s land is shared for agricultural purposes: both very interesting examples of land sharing where two or more stakeholders can get economic benefits from the same territory. 



Stream Sharing

With this challenge, Enel Green Power and Thermal Generation is looking for new ideas, or solutions already applied outside Enel, for the possible implementation of the sharing practice in our business line, taking into account all of the technologies we operate in different countries.

This challenge provides contribution to the following sustainable development goals (SDGs) to transform our world:
  • SDG 7: Affordable and Clean Energy;
  • SDG 9: Industry, Innovation and Infrastructure;
  • SDG 11: Make cities and human settlements inclusive, safe, resilient, and sustainable;
  • SDG 13: Take urgent action to combat climate change and its impacts;
  • SDG 15: Life on land.



Challenges rules

This challenge takes place in a non-collaborative environment, meaning that the interaction regarding the submission is private, between Enel and the proponent.

The Applicant must have reached the age of majority according to Italian legislation, but not older than 35 years of age, and have legal capacity in the jurisdiction where he/she resides. Only single natural persons are allowed to participate.

The Applicant must have applied for the Carta Giovani (Youth Card) through the app IO. In order to participate in the challenge and provide an innovative solution, you must get the application code available at Carta Giovani (Youth Card) through the app IO.

The code will be required in the form to fill in with the solution information.

In addition to the uploading of the solution on the Open Innovability® platform, the Applicant must upload his/her personal resume (CV) on the Enel.com website (https://www.enel.com/careers/working-at-enel/spontaneous-application) using the same name, surname and e-mail address used to register on openinnovability.com.

All proposers are invited to read carefully the challenge and its regulations, attached below in the Attachments section, before submitting a solution.

By submitting a solution, they automatically accept the attached Regulations in addition to the Terms of Use of this platform.

Explain your proposal clearly in English or Italian and attach documents if needed. (max 5 files, 3MB each).

The winning Applicant will have the chance to enter the selection process either for an internship or a job with Enel Spa (or any other of its subsidiaries), subject to the positive outcome of any eventual necessary checks required by law and/or Enel internal policies (e.g. in case of conflicts of interest). The internship will be paid with an amount of 800 euro per month plus benefits.



Submissions to this Challenge must be received by 11:59 PM (Central European Time) on January 31, 2023.

Late submissions will not be considered.

Specific regulations in the CSA attached at the bottom of this page.

What happens next

Enel will evaluate the Proposals, getting in touch with the Solver if additional information is needed.

Following this preliminary evaluation, the Proposal(s) that meet the requirements of the challenge will be further evaluated by one or more relevant Enel companies and/or business lines.

Enel will evaluate the proposal using the following criteria:

  • Overall scientific and technical feasibility of the proposed solution;

  • Economic potential of concept (e.g. Total Cost of Ownership);

  • Business potential for Enel;

  • Novelty and non-obviousness;

  • Potential for proprietary position (i.e., is the technology novel or protectable);

  • User’s capabilities and related experience;

  • Realism of the proposed solution;

  • Maturity level of the proposal.


At the end of the assessment, you will receive feedback.

In case of success, an Enel contact person will get in touch with you to discuss the next steps. No detailed evaluation of individual submissions will be provided.

The winner of the challenge is subject to the positive outcome of the Enel recruiting process.
