ESE helps you to realize your power production projects. We deliver complete technical and feasibility studies, basic and advanced designs up to tender documents preparation and business plans.

Among the services we offer, Owner’s engineering service is the one that made us known for the high competence and experience.

Concentrated solar Power (CSP)

ESE is at the forefront of the development of dispatchable renewable energy technology thanks to its involvement in Concentrated Solar Power (CSP).

Concentrated Solar Power plants capture the energy of the sun and convert it into heat, finally generating steam that powers a steam turbine to produce electricity. The advantage over traditional photovoltaics is their predictability and dispatchability: solar energy gathered when the sun is shining can be stored in a thermal medium and then used at any time during the day and the night to produce clean, safe, dispatchable electricity promoting stability and balancing of the grid.

ESE has a long CSP experience on direct steam, parabolic trough, fresnel and central receiver technology, and capability for consulting and design on power block, thermal storage, steam generation, solar field and receiver systems.

Borrowing the molten salt technology from the CSP field, ESE has been recently studying the application of molten salt as a thermal energy storage medium in conventional plants and industrial environments, with interesting results.

Engineering leader in the CSP and Thermal Energy Storage fields, ESE is capable to provide extremely variable services, from feasibility studies to support in technology assessment, from equipment engineering to cycles and plant development.

  • Wood chips,
  • Straw,
  • Rice hulls,
  • Energy sugar cane,
  • Eucalyptus,
  • Bagasse,
  • Vegetable oil,
  • Chicken litter.

ESE experience covers the complete development process, from the authorization phase until the commissioning of the plant. ESE also supported WtE (Waste to Energy) Boiler makers in their effort to approach the Italian market.

Hydroelectric Power Plants

ESE is dedicating itself to hydro-electrical power covering a wide range of hydroelectric plants, from conventional ones to pumping storage plants in the most various regions of the world.

ESE has developed a strong partnership with important Civil Engineering Companies being in this way able to offer a comprehensive engineering package that includes special civil works (tunnels, dams, underground power stations).
ESE can successfully provide several kinds of different services:

  • Feasibility Studies,
  • Business Plan,
  • Preliminary Design,
  • Cost Estimation,
  • Tender Documents,
  • Conceptual, Basic and Advanced Basic Design,
  • Preparation of technical documents for Permits,
  • Owner’s Engineering Services,
  • Modernization for existing plants.

Photovoltaic Plants

Working with its partners, ESE has developed an important knowledge about PV plants and Electrical Energy Storage with Batteries.

Cooperating with TrendEnergy from 2015, ESE is able to fully support its client in the configuration, estimation, full design and construction supervision of the project, for PV plants (with and without tracker) with and without Battery Storage.

Furthermore, the large experience in the costing activities developed by ESE and the specific knowledge in this field allows ESE to be a very reliable partner in the estimation of the plant cost and in the optimization of the configuration.

Gasification and Pyrolysis

ESE has expertise and knowledge in small gasification and pyrolysis plants for plastic waste and biomass. ESE can support you in the study of such technologies for waste/biomass to fuel and waste/biomass to power applications, providing the following services:

  • Technology and operational experience assessment
  • Feasibility study
  • Study of integration into larger plant
  • Follow-up of design and construction

In addition to its technical skills, ESE is also exclusive promoter for the Italian market of the Intravis gasification technology for biomass and Refuse-Derived-Fuel.

Energy storage

ESE can support you in the study of energy storage solutions, both for thermal and electric applications. Thanks to its experience gained in conventional and renewable power applications ESE can support you in the conception, study, follow-up, design and construction of:

  • Electricity storage based on batteries
  • High temperature TES (normally based on molten salt technology)
  • Low temperature TES (water and steam accumulation)

…and their coupling with the grid, the electrical or process system of your plant.


Knowledge-based solutions with you for the additional services you can need for your power production project.

Due Diligence and Energy Audit


ESE supports the investors in the Due Diligence of existing plant, analysing the plant conditions and estimating the expected remaining life and the values of the assets.
When requested, the Due Diligence activity also includes the study for a rehabilitation program, evaluating the possible plant improvements and the relevant economic and performance impact.
ESE also performs Due Diligence of projects under development to verify the status of the initiative, possible hidden problems or potential unexpected issues.


ESE performs Energy Audits for power/industrial installations, performing the analysis of the plant’s processes and the relevant heat/cold and power needs, and reviewing the electrical and thermal consumptions.
One of the most important goal of this activity is the optimization of the process, the reduction of the consumptions and the improvement of the total energy conversion efficiency.
Inside the European Union, the Energy Audit is performed by certified Energy Management Expert (UNI CEI 11339) following the European Directive on Energy Efficiency Dir 2012/27 / EU, that entered into force on 4 December 2012 and the correspondent Italian Legislative
