Zelya Energy has put its expertise at the service of wind power producers, to assist them in the calculation and issuance of their electricity sales invoices. Most wind farms in France benefit from the so-called "purchase obligation" rates and must therefore, each month, issue an invoice to EDF Purchase Obligation (or the local electricity distributor) to collect the revenues from their production.
Our teams have developed numerous tools for modeling and simulating wind electricity tariffs, taking into account the production histories specific to each site, tariff rules and indexation coefficients provided for by regulation.
This expertise and these tools allow us to offer a useful, precise service, consisting in generating for our client portfolio of wind producers, the invoices intended for their local distributor or EDF Purchase Obligation.
The WIDEO billing assistance service allows you to simply calculate and issue your invoices in a few steps:

The net cash flow method, also known as the English term Discounted Cash Flow (DCF), is very 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 yields" and is based on the implementation of a fundamental formula.
With their experience in valuing networks and energy production plants, the financial experts at Zelya Energy, who are very knowledgeable in the wind energy sector, assist you in validating your valuation or for:
In France, the grenelle II law of July 12, 2010 regarding national commitment for the environment has subjected wind farms to the regime of Classed Installations for Environmental Protection (ICPE).
At the same time, this law made the commissioning of wind turbines subject to authorization dependent on the demonstration, by the operator, of its technical and financial capabilities. As for financial capacities, it is notably about the operator providing financial guarantees aimed at ensuring that the cost of decommissioning and restoration of the site in case of operator's failure will indeed be borne by the latter.
Technical and financial capacities are assessed by the administration and the judge based on "bundles of indications", which are just as many criteria that need to be understood and proven when drafting the note demonstrating the technical and financial capabilities.
Zelya Energy supports you to demonstrate to the administration that you do indeed have the technical and financial capabilities allowing you to obtain the decision authorizing the operation of an ICPE:
Future wind farm operators must produce a hazard study file in their application for operating a Classified Installation for the Protection of the Environment (ICPE).
This is an obligation resulting from article R512-1 of the Environment Code, while article R512-9 of the same code describes the content.
In certain cases, and as needed, this hazard study needs to be updated.
Zelya Energy supports you in the establishment or update of the hazard study file:
We compile the hazard study file with you in close consultation with the prefectural administration (DREAL and DGPR) and supplement it with aspects specific to your project.
We ensure the hazard study is in compliance with relevant regulatory provisions (decrees, orders, circulars, etc.), as well as taking into account the formalized recommendations of the profession and best practices.

Full technical inventory
Technical due diligence is a complement to regulatory due-diligence. It validates general technical characteristics and quantifies uncertainties and risks related to quantities forecasted for a wind farm or portfolio.
More specifically, it aims to :
identify potential inconsistencies between sizing and production, operation and maintenance conditions
validate the general technical characteristics of the farm or portfolio: resource, losses, performance, availability, production
quantify uncertainties and risks that could negatively impact these technical characteristics;
prescribe realistic assumptions for these technical characteristics for the financial valuation model;
recommend, list and prioritize appropriate conditions precedent in the context of a purchase offer
To evaluate the production to be considered and quantify the uncertainties and risks of its value, we proceed to the following tasks :
collection of relevant documents: equipment supply contracts, operation and maintenance, insurance, connection and access to networks, resource study and production, etc
Technological analysis and evaluation of the overall sizing of equipment
review of resource and production study
analysis of technical clauses of contracts: performance, raw, guaranteed and insured availability and production
The study of the technical conditions for connecting a farm or a wind portfolio to electricity transport or distribution networks is a complementary part of the technical due diligence.
It is required when it is necessary to examine more specifically and in detail if the connection is optimized from a technical and electrical point of view (acceptable level of line losses up to the delivery point, reasonable grid unavailability rate and reductions, ... ), and more generally, if the sizing and operating conditions of the internal electrical installation comply with that of the connection to the electricity networks.
More specifically, it aims to :
identify possible inconsistencies between the sizing and operating conditions of the internal installation and the connection infrastructure
validate technical characteristics of the connection
quantify uncertainties and risks that could negatively impact the wind farm's production
prescribe realistic assumptions for these technical characteristics for the financial valuation model
recommend, list and prioritize appropriate conditions precedent or possible improvements
For a projected wind farm or wind portfolio, it is possible to complete the analysis of the only generally available documents (connection studies, technical and financial proposal) by a prospective analysis of the foreseeable connection agreement, operation agreement, and network access contract, given the current regulation
The audit of the actual condition of equipment of a wind farm or a wind portfolio in operation is a complement to technical due diligence.
It allows to verify that the mechanical, electrical, hydraulic equipment is in good working and maintenance condition and to establish, where applicable, a list of measures to be taken and replacement equipment to be stored
More specifically, it seeks to :
take an inventory of installed equipment
qualify the actual state of the mechanical, electrical and hydraulic equipment and their maintenance
quantify their expected lifespan for the financial valuation model
identify measures to be taken before or after the transaction
recommend, list and prioritize the appropriate conditions precedent: replacement measures to be taken, equipment to be made in stock...
The opportunity and scope of the technical audit of a farm or portfolio in operation can be decided based on the results and recommendations of the technical due diligence, the performance study and the warranty and maintenance study.
In particular, depending on these results, visual inspection and certain specific tests can be targeted on a sample of machines only (infrared, gearbox endoscopy, vibration analysis, isolation test,...)
The on-site audit by visual inspection typically covers the blades, the HV and LV cabinets, the generator, the power electronics, and the gearbox. Other specific tests are performed.
The study of the real performance of a wind park or a wind portfolio in operation is a complement to technical due diligence.
Its purpose is to identify the reasons for the sub-optimization of production given the operating conditions and, in particular, to quantify the impact of maintenance operations on the availability of the wind park, and thus, to verify whether the conditions of maintenance and the guarantees subscribed are optimal.
More specifically, it aims to:
estimate the real guaranteed and non-guaranteed unavailability of each machine and the park as a whole
identify the origin of unavailability
make recommendations on the values of real technical characteristics to be considered in the financial evaluation model
make recommendations on the machines that could usefully be subject to a technical audit on site and control tests
analyze the relevance of the warranty perimeter and the level of guaranteed availability per machine and for the park as a whole.
The study of the real performance of a wind park or a wind portfolio in operation requires the following tasks:
Collection and analysis of relevant documents: production, operation and maintenance reports, maintenance contracts and protocols, list of failure codes, etc.
Estimation of real site resource characteristics, gross unavailability rate by origin
Analysis of the occurrence and duration of preventive and corrective maintenance operations by machine
Verification of the effectiveness and relevance of corrective maintenance operations given the type of failures observed, as well as the opportunity and consistency of preventive maintenance operations given operating conditions (wind speed)
Simulation of the actual power curve and estimation of actual producible, yield and actual annual operating hours
Comparative analysis of the real characteristics of the wind park with those provided by the equipment manufacturer or estimated in the site resource and producible study.
the availability rate of each turbine and wind park,
fundamental technical parameters of equipment (oil, temperature, sound),
the origin and occurrence of stops and their associated losses,
the theoretical production that each turbine should and could have reached...
