GP Wood Ltd
(Irland / Enniskeane)
Checking of the economic and technical feasibility of an extension to a sawmill site by a biomass combined heat and power plant and a pellet production plant in the context of a feasibility study.
GP Wood Ltd., based in Enniskeane, operates two sawing lines with a total capacity of 300,000 m³ per year. Since 2005 the company has been operating a biomass cogeneration plant with an installed electrical output of 2.5 MW and thermal output of 4.5 MW. The company’s own by-products such as sawdust and bark are used. With a view to greater independence as well as an increase in the added value of its own activities, the company investigated the potential of a pellet production unit for the use of its own available wood chips and sawdust, as well as the freely available quantities of heat from the existing combined heat and power plant.
On account of the EU directive, Ireland has a binding legal obligation to secure a share of 16 % renewable energies by the year 2020. Hence, the option of investing in a new combined heat and power plant also had to be investigated.
In this context W.T.T. was commissioned in 2013 with the consulting as well as the feasibility study. This included not only the analysis and simulation of possible extension scenarios or the use of the existing resources, but also the recommendation of an optimised industrial concept, taking into consideration all possible local synergies as well as maximum economy and flexibility. The simulations included the preparation of an investment budget extending to the determination of the running costs of the future site.
Following the conclusion of this study, W.T.T. will advise the customer GP Wood about the next steps with regard to a project implementation
