Zelya Energy

The net cash flow method, also known as Discounted Cash Flow (DCF), is widely accepted in asset valuation (company, project or portfolio) due to its solid theoretical foundations.

It financially translates that an asset "is worth what it brings in" and is based on the implementation of a fundamental formula.

Our services

With their experience in network and energy production unit valuation, the financial experts of Zelya Energy, who have a thorough understanding of the biomass sector, assist you in confirming your valuation or for:

  • determining the duration of the evaluation, depending on the investment time horizon, the lifespan of the facilities, the contract term, etc.;
  • modelling expected cash flows: tariffs and selling prices of electric production, operating costs - OPEX, investments - CAPEX, taxes, levies, etc.;
  • estimation of the terminal value, taking into account dismantling costs, material recycling, legal constraints, etc.;
  • calculation of the WACC, used as a discount rate, which is the most sensitive parameter of the DCF valuation is the discount rate ;
  • determining the value of the assessed asset (company, project or portfolio).

The physico-chemical characteristics, notably the humidity and the calorific power, may greatly vary depending on the geographical origin, species, etc.

However, knowing the physico-chemical characteristics of the wood resource can be essential for:

  • assessing the producible power of a power plant or cogeneration plant or a heat boiler;
  • checking the compliance of the fuel with the boiler's characteristics;
  • defining the quality characteristics of the fuel in the supply contract;
  • confirming compliance with greenhouse gas (GHG) or harmful emission thresholds set by the regulations.

To this end, it is possible to have several physico-chemical characteristics certified by a laboratory: composition of the raw and dry wood, moisture content, melting point, inferior calorific power, etc.

Our services

Zelya Energy, in partnership with an accredited laboratory, assists you in determining and certifying the physico-chemical characteristics of your wood resource, before commissioning or during operation, while taking care to respect a certain number of precautions:

  • precisely define, depending on the targeted objective, the physico-chemical characteristics to be certified;
  • ensure that the laboratory fully respects the applicable certification standards depending on your resource;
  • interpret and use the certified data to calculate the producible power, quantify the GHG emissions, check the regulatory thresholds, etc.

The future operators of power plants producing electricity, boilers producing heat, as well as cogeneration plants from biomass, must produce a hazard study file in their application for a classified installation for environmental protection (ICPE). 

This is an obligation resulting from Article R512-1 of the Environment Code, while Article R512-9 of the same code describes its content. 

In some cases, and as needed, this hazard study must be updated. 

Our services

Zelya Energy supports you in the establishment or updating of the hazard study file:

  • writing of the non-technical summary ;
  • development of risk mapping ;
  • description and analysis of the installations, environment and neighborhood ;
  • identification, characterization and reduction of potential hazards ;
  • accident analysis ;
  • risk assessment ;
  • modeling of dangerous phenomena ;
  • analysis of possible domino effects ;
  • presentation of organizational and management measures.

We put together the hazard study file with you in close consultation with the prefectural administration (DREAL and DGPR) and complete it with aspects specific to your project.

We ensure the compliance of the hazard study with the relevant regulatory prescriptions (decrees, orders, circulars, etc.), as well as the consideration of formalized recommendations by the profession and best practices. 

 

 

You are a developer or operator of a power or cogeneration plant producing electricity and heat from biomass connected to the distribution (HTA) or transportation (HTB) network of electricity.

Regulation requires you, in order for it to continue to inject and sell the electricity it produces, to submit your installation to a conformity and performance control for the connection.

You are obliged to do so on several occasions: when first commissioned, when restarted after a substantial modification or a shutdown for more than two years, during a periodic control or after a malfunction of your installation.

Concretely, you must, under your sole responsibility, issue conformity certificates for your equipment and perform electrical calculation studies. In addition, you must participate, with the network manager, in collation, testing and verification operations.

Our services

The project managers and engineers at Zelya Energy support you to facilitate the compliance and performance control of your installation, i.e. to:

  • Validate the list of collations, attestations, tests, studies, verifications, surveillances, that must be carried out according to your connection (transport or distribution) and your situation (first commissioning, restarting, periodic control or after malfunction);
  • Check the conformity of the electrical sizing of your production installation and obtain conformity certificates from the manufacturers;
  • Carry out the studies (short circuit contribution, current harmonic emission, etc.), calculations and optional type simulations (low voltage ride through, reactive power production and consumption capacity, exceptional frequency regime resistance, etc.) required by the regulation;
  • Identify, compete, verify the qualifications and supervise the verification body you have eventually chosen to carry out the collations, tests, trials and verifications.

If you are an operator or developer of collective boilers, cogeneration power plants or electricity production from biomass, you strive to size or supply your installations in coherence with the characteristics of the used wood. In relation to your suppliers, your concern also consists of securing the wood supply, that is to say the necessary quantity, but also the inherent quality of the wood (energy density), in order to include in your contracts clauses specifying these characteristics.

If you are the buyer of a heating plant or a biomass power plant, the validation of the deposit and of the producible is essential to reinforce the technical-economic assumptions of your financial valuation model.

The actual quantity of heat or electricity generated by a plant operating on the principle of biomass combustion certainly depends on the chosen technology (efficiency, minimum and maximum fuel flow, etc.) and the operating conditions (fuel flow, availability rate, stops, maintenance operations, etc.), but more simply on the physico-chemical characteristics of the consumed fuel.

Our services

Zelya Energy supports you to:

  • Determine the characteristics of the relevant fuel to be tested according to your need: sizing of installations, securing the supply contract, validation of the production assumptions of your financial model;
  • Ensure that the tests carried out by a laboratory comply with standards and current regulations;
  • Certify the physico-chemical characteristics of the fuel in accordance with standards and regulations;
  • Estimate the producible taking into account the choice of technology, operating conditions and technical characteristics of the consumed fuel;
  • Check during operation, by a physico-chemical analysis on a fuel sample, that the clauses of the supply contract are respected and that the performance of the plant is optimal.
