ESE has been selected by S.ENE.CA. S.r.l. as technical consultant for the due diligence activities associated with the hospital tri-generation plant in Careggi, Florence. 

The aim of the study is to provide a clear picture of the plant evolution, starting from its conceptual design to today’s status up to its future development. 

The analysis will highlight the areas of environmental, performance and O&M potential risks which may constitute an obstacle for satisfying the hospital energy demand up to 2030.

ESE would be glad to continue its collaboration with S.ENE.CA. and provide its technical support for optimizing the plant performance and help reducing the energy bill for the benefit of the hospital and the entire community.

ESE is glad to announce that it has been involved in the feasibility stage of a 600 MW green hydrogen production plant. The project is carried out by the Apulian start-up Hope srl and consists in the production of hydrogen from the energy generated by an off-shore wind farm located on Apulian cost. 

The preliminary sizing of the electrolysis plant already comprises technical and commercial assessments which represent a challenge as such a plant size has not been deployed in any part of the world. 

ESE, in partnership with Stream – Energy and Environment, is glad to share that it has officially joined H2IT – Associazione Italiana Idrogeno e Celle a Combustibile (hydrogen and fuel cells Italian association).

ESE is supporting Inka's Boiler for the development of an innovative cogenerative biomass power plant in Brazil, fuelled by bagasse, a waste product of the sugar industry which is very well spread and developed in the area.

The project is developed in collaboration with the São Paulo Research Foundation (FAPESP). 

The power plant shall produce electricity and steam needed from the sugaring process and its innovative design consists in the implementation of a reheating section in order to enhance the plant efficiency.

ESE is providing technical support for the design of the boiler and for the improvement of the thermodynamic cycle of the plant. 

ESE is technically supporting its Client to provide an evaluation of the status of two Power Plants — two existing combined cycles that were formerly located in Italy and then transported and reconstructed in Ghana.

However, the plants never achieved mechanical completion. ESE therefore aims at identifying possible critical aspects to be further investigated before commissioning and progress of the works.

The focus and objective of the due diligence are related to the simple cycle components only.

A final report will be carried out after a dedicated site visit took place.

Israel’s electricity market is undergoing significant changes in the wake of a 2018 structural reform. Indeed, as part of the reform, Israel Electric Corporation (IEC) – the state-owned utility company – is selling part of its power generation sites to private Independent Power Producers (IPP’s).

In this context, Noy Fund and Shapir decided to embrace the opportunity and partecipate to the tender for purchasing the East Hagit Power Plant (660 MW) supported by an O&M Contractor and a LTSA Contractor.

As technical consultant, ESE supported Noy Fund and Shapir through the negotiation and tender preparation process partecipating to the following activities:

– Technical due diligence

– Evaluation of optimization opportunities for the existing plant

– Evaluation of technical alternatives to increase the plant capacity

– Support for bid preparation

ESE and CESI have been requested by A2A to supervise as a third party the performance tests required for the revamping of A2A’s Cassano d’Adda Combined Cycle Power Plant (750 MW). Revamping includes important interventions on the Gas Turbines (GE-9E) and the Steam Turbine, to increase the capacity and the efficiency of the Power Plant. 

ESE and CESI verified the consistency of the procedures with the contractual obligations, the reference standards and the plant configuration. The scope of work also includes the analysis of the instrumentation calibration certificates, the correct identification of the thermal cycle insulation points, the supervision of the tests and the verification of the final report. 

Several performance tests have been conducted: base load, 70%-part load and N2 packing leakage test. The last one has the purpose of determining the steam which leaks from the first stage of the HP turbine to the IP turbine bowl along the N2 shaft packing and the IP turbine section corrected efficiency.

In addition, a model of the plant has been built with the modelling software Thermoflex, to recalculate the correction curves issued by the Contractor.

ESE, in partnership with STREAM, has been awarded by CESI the lifetime extension study of a thermal power plant built in the early 2000s.

An assessment on the status of the plant has been performed, in particular for the electro-mechanical part and the MV and HV distribution lines.

Moreover, the necessary corrective actions to achieve the desired improvements were identified at a design level and verified through a dedicated site visit.

Finally, the total investment cost and the financial return of such measures were quantified.

ESE, as a part of STREAM consortium, conducted a due diligence of ERG Hydro Power Plants fleet in Central Italy. In particular, electro-mechanical aspects were investigated to evaluate plants status and future developments. Together with STREAM, also civil, safety and legal aspect were examined, underlying the impact of the close future changes in Italian legislation about water concessions.

Moreover, site visits were conducted for the 7 major hydro plants of the fleet, gathering important information. For the whole fleet, an analysis of databases and historical data was also carried out.

With this project, ESE continues its growth as a consulting company for sustainable energy production, always respecting the use of water resources.

In the picture: Francis turbines from Cotilia power plant.
