Summary • Liguria and ARE Liguria: who we are • The Regional Energy Plan • Link with Robinwood • Our “choices”… • What we have done practically • Val di Vara • Val Bormida • Other projects going on in Liguria • Robinwood deliverables
GENOVA SAVONA LA SPEZIA IMPERIA 1. Liguria Region • Population: 1.560.748 inhabitants • Area: 5.421 km2 • Provinces: Genova, Savona, La Spezia, Imperia • Municipalities: 235
ARE Liguria S.p.A.: who we are ARE Liguria S.p.A. is the “technical structure serving the Region of Liguria in the area of energy policies and sustainable development” (Regional Law no. 18/99) INSTITUTIONAL ROLE Carrying out regional policies OPERATIVE ROLE Taking initiative, promoting and participating directly in the implementation of projects • Technical Support to Public Administrations • Managing relations between local government and private/public operators • Solution finding for projects in the energy field • Promoter of projects with renewable energy sources • Dissemination and Education
2. The Regional Energy Plan • In December 2003 the Region of Liguria approved its Regional Energy and Environmental Plan (PEAR) with the following objectives by 2010: • Stabilise emissions to 1990 levels; • Increase energy efficiency in the most consuming sectors; • Reach at least 7% of the total energy production through RES
Implementation approach TWO phases: 1. Testing: Energy Plan to be tested in pilot areas (best practices) in 2003-05 2. Implementation: throughout the Region in 2006-2010.
What is a “pilot area”? Pilot areas, selected by the Region together with Local Authorities, are conceived to find and test: economic feasibility repeatibility of interventions especially in the field of renewable sources of energy.
Objectives of the pilot areas • Test the implementation process of the Plan • Find and measure the tools to apply afterwards to the whole regional territory.
Pilot areas: selection criteria Socio-economics Territorial planning (PTR, PTCP, ECC) Renewable energy potential Energy demand Environment Infrastructures Technology From the macro-criteria: territory and energy we derive more specific criteria Territory Energy
Energy from wooden biomass Solar thermal in tourism Energy savings in buildings Energy efficiency in industrial areas through self-production Special interventions in the fields of wind energy and small-hydro Pilot areas
3. Link with Robinwood… Resorting to woodland biomass becomes particularly important as a way of protecting and safeguarding the natural environment. The use of this energy source could mean the reclamation of neglected woodland areas, not only for recreational and cultural reasons, but also as a means of developing a defence against fires and hydro-geological disruption, two illnesses which devastate vast areas of Liguria every year.
3. Link with Robinwood… Objectives Strategy Manage and care abandoned forests Prevent fires and hydrogeological disorders Promote the economic exploitation of wood (agricolture, tourism, handcraft, commerce, etc.) Increase employment Forest management Wood residues for energy Small heating plants
4. Our choices: Wood to energy PEAR classification for wooden biomass Wood to energy Waste to energy
Biomass sources Following PEAR classification, biomass can be divided in: • Wooden biomass originating from forestry use in the woodland areas • Wooden biomass originating from scraps, woodchip, saw-mill (untreated) • Wooden biomass originating from the upkeep of urban parks and gardens
Sizes of wooden biomass power plants • Target: to install a capacity of 150 MWth (also in CHP) • Priority: thermal power < 300 MWth (per plant) • Size suggested by PEAR: 1-4 MWel
Tools for the implementation of wood chain • Financial tools: incentives, taxes, etc. • Administrative tools: shorter procedures, Sportello Unico (special single office that gives all autorizations) • Marketing tools: labelling, promotion and dissemination • Sustainability tools: Environmental Impact Assessment, Environmental Strategic Assessment, EMAS, ISO 14000, energy certification • Evaluation and monitoring tools
Tools for the implementation of wood chain • Managerial tools: ESCos, cooperatives, multiutility companies • Cooperation tools: partnerships with local stakeholders and between regional/local authorities • Technical assistance: for start-ups • Technical tools: building regulations, feasibility studies, Informative Energy System
Approach For a correct biomass plant project it is necessary to take into account: • Energy demand (especially thermal energy) • Availability of wooden biomass • Availability of suitable areas • Possibility of grid connection (in case of electricity production)

A. Wood fuel report for Liguria Region - 2 Conclusions and recommendations The analysis highlights: • potential development for wood fuel market, deriving from the high availability of woodland biomass of the territory • obstacles rising from scarce attention to the management and maintenance problems of woodland asset and rural areas often characterised by progressive depopulation of both inhabitants and industries connected to the local resources. Regional Energy Environmental Planplanning instrument both for energy and environment. Through the promotion of the use of wood fuel and the support to troubled sectors connected to the wood resources, the Plan seeks for successful effects on a local scale, also in terms of employment generated by new local industries. • solutions for the improvement of woodland biomass • foundation for the successful replication within the regional territory, of plants and organisational and managerial schemes based on associations of forestry management that, together with the traditional timber products, are capable of energy production within a technically viable and economically sustainable process. pilot areas
Short-medium term perspectives for wood-energy in Liguria • Small district heating plants • For public/private users • - Demand for spot thermal energy • - Lack of funding • Co-generation plantsin industrial areas/wood transformation • - Critical point: small size for scarce resources availability • - High cost of wood chips (> 0,45 €/ton) • Plants for pellets production • - High demand of pellets • - Small demand of wood chips (19.000 tons/year) • - Funding of Environmental Ministry • 10% plant • 30 – 50% stoves
B. Regional resources available Information about usable resources concerning wood energy in Liguria comes from: • Forestry Map (2002) official Regional Technical Map - scale 1:25.000. • Land Use Map (2000) originates from the CORINE legend - scale 1:25.000.
Forestry map Forestry Map It ensures an immediate view of useful territorial reference points, permits the organisation of forestry/woodland themes on a geometrical matrix identical to all the different products on the Territorial Informative System of the Region of Liguria (S.I.T.A.R.) For each forestry/woodland theme it is possible to know the surface and the perimeter
Land use map Land Use Map It indicates the inhabited and settled areas, burnt land areas, anthropic strips and terracing, inlay of the categories, artificially (manmade) shaped terrain, farming land, woodlands and semi-natural environments, humid areas, water, etc. The Land Use Map originates from the CORINE legend (CORdination de l’INformation pour l’Environment)
C. Analysis of wood resources - 1 The theoretical potential of extractable wood biomass was calculated on the basis of woodland surface area which could be cut down annually in accordance with an appropriate turnover system, followed up by quantifying the volume of biomass that could, in theory, be extracted while leaving the forestry patrimony intact. • percentage of the areas annually felled set at 2% for each type of high forest and 4% for copses. • turnover of the trees, aged 50 for high forest and 25 years for copses, takes into account an operation of tree-felling that does not cause alteration to the area’s natural physiology. • volume mass, for dry substances in high forest, of 0.45-0.60 t/mc (as per type), in comparison with timber production equal to 300-400 mc/ha, while in the case of coppices the mass to be used is 0.70 ton/m3 (dry material) and timber production is set at 140 m3/ha. Next step: find more detailed data for every single mountain community
C. Analysis of energy demand • THERMAL • available data only • for domestic heating for • every municipalities • (not derived from a • survey but from calculations) • ELECTRICAL • available data for • every province (derived • from a survey) per sector • (buildings, industry, agricolture) Difficulties to overcome • Lack of information on thermal consumpion • Different level of fragmentation (region, province, • mountain community, municipalities)
D. Selection of technologies On the basis of results achieved in the pilot areas, the most interesting technologies for Liguria are: • District heating (especially for public users) • CHP (<5MW) with classical Rankine Cycle or with Organic Rankine Cycle • Pellets stoves • Pellets production plants
