The actual amount of heat or electricity generated by a power plant operating on the principle of biomass combustion depends not only on the chosen technology (efficiency, minimum and maximum fuel flow, etc.) and operating conditions (fuel flow, availability rate, shutdowns, maintenance operations, etc.), but more simply on the physico-chemical characteristics of the consumed fuel.
The main characteristics are:
Within the framework of assessing a fuel's energy potential, and as a first approach, the electrical power of an electricity generation plant or the thermal power of a boiler operating on biomass can be described as follows:
This formula reflects the main factors that have an impact on electrical or thermal power:
Of course, these characteristics depend on temperature and pressure conditions, but also on other physico-chemical characteristics, such as the moisture content.
The physico-chemical characteristics are intrinsic properties of the fuel.
The nature of the fuel (wood for example), is not the only influencing factor. A large variation in properties is observed depending on the moisture content, ash content, species, particle size distribution, etc. Some models and databases provide average statistical properties, which are useful if no sample is available.
For a given wood sample, however, these characteristics can be tested, determined, and certified by laboratory analysis tests. These tests are subject to precise standards and procedures, defined by regulation or by the profession, particularly under the impetus of ADEME, which must be observed.
Thus, for example, the lower heat value can be determined by theoretical calculation, by direct reading on a chart, or by combustion in a calorimetric bomb.
Zelya Energy supports you in validating and certifying the physico-chemical characteristics of your biomass and estimating the output of a power plant or boiler.
The Territorial Supply Plan (TSP) for bioenergy wood aims to establish, optimize and secure the supply of energy wood.
The TSP is a strategic and operational decision-making tool for local elected officials and project owners or operators of electricity and/or heat power plants running exclusively or partially on bioenergy wood.
It helps to better understand the balance today and in the future of the resource - available quantity (forest, primary and secondary processing industries) and necessary quantity (industrialists, community heating plants, electricity production and cogeneration, biofuel) - to identify the possibility and opportunity to develop a bioenergy wood sector, to establish the organization and tools necessary for coherence between sectors and long-term supply security, to identify the levers and impact of a potential public action.
Carried out on a relevant territorial scale that may exceed the competency territory (countries, regional natural parks, community of communes, community of agglomerations, etc.), it is evolving and updatable. The implementation of the TSP is committed to the valorization of local energy potentials, according to a territorial coherence logic (agricultural policy, territorial planning policy, fiscal policy, economic, industrialization and employment policy, etc.). Finally, the TSP must be developed in consultation with local stakeholders in the wood sector to give it full legitimacy.
For elected officials, the TSP allows to achieve many objectives:
The TSP provides a basis and legitimacy to build a truly coherent long-term strategy and implement operational actions in the short and medium term.
It also serves as a support point for:
For developers of power plant or heating plant projects, the TSP allows to validate the quality and security of supply, to quantify the cost of the resource and to identify suppliers towards which to engage supply negotiations.
The order of August 10, 2012, which came into effect on September 6, 2012, came to specify the list and level of investments allowing an installation governed by a H-97 contract to benefit, under the same conditions, from a new power purchase obligation contract, in accordance with article L. 314-2 of the energy code.
This order subordinates the benefit of a new power purchase obligation contract H07 (after the expiry of the H97 contract) to a certain level of renovation investment, among the investments which it definitively lists.
If your installation and your investments are eligible, you must proceed with the development of an investment program, obtaining a power purchase obligation certificate and signing a power purchase obligation contract H07.
The cumulative investments over a continuous period of 8 years is at least:
The accumulation of investments made at the end of the first four years of the eight-year period must at least reach 60% of the above values.
As of January 1, 2013, these values are indexed annually on January 1 using a coefficient K'.
The eight-year period begins at the latest at the expiration of the H97 contract.
The amount of investments taken into account can include the amount of investments that have actually started but are not yet completed at the due date of the current contract.
Among the investments, it is possible to include in particular technical studies and file preparation, study fees with authorization file. In addition, the order precisely lists the main civil engineering works, main components, turbine, generator, regulation and other eligible electrical components.

The General Commission for Sustainable Development published in its n°348 of its "Figures and Statistics", the data on the French photovoltaic solar park as of June 30, 2012, ending the second quarter of 2012.
This note highlights an increase in installed and connected capacity, marked by the arrival of large installations with a power greater than 5 MW, but with a downturn compared to the semester of the previous year.
The General Commission for Sustainable Development published in its n°348 of its "Figures and Statistics", the data on the French terrestrial wind farm as of June 30, 2012, closing the second quarter of 2012.
This note highlights a significant slowdown in installed and connected capacity not only compared to the last two quarters, but also compared to the same semester of the last three years.
However, "as of the end of June 2012, the projects entering the queue are seeing a very strong increase".
