  3. EU-30 – Dependence according to energy product Source: European Commission

  4. The problem Trends in the European Union: An increase of energy consumption not balanced by an adequate production increasing external dependence of energy products (actually imports 50% of its energy requirements but it could rise to 70% within the next 20 to 30 years if no measures are taken) structural weaknesses of energy supply It is necessary to introduce a strategy of security aimed at reducing the risks: • Economic (steady rise in oil prices) • Social • Ecological (damages caused by the energy supply system: accidental or related to emissions of pollutants) • Physical Community dimension of energy policies to manage the interdipendency of Member States to: • combat climate change • complete the internal market

  5. "Towards a European strategy for the security of energy supply" of 29 November 2000 [COM(2000) 769] The Green Paper Objective of a long-term energy strategy: • “… to ensure the uninterrupted physical availability of energy products on the market at an affordable price for all consumers, whilst respecting environmental concerns” • to reduce the risks linked to energy dependency (specially regarding fossil fuels such as petroleum - the dominant resource) • to rebalance EU supply policy by clear action in favour of a demand policy, aimed at controlling its growthby encouraging a real change in consumer behaviour through, for example, taxation measures. • to combat global warming with regard to supply, promoting new renewable energy sources for example, financing their development with financially viable energy. • to provide a stronger mechanism to build up strategic stocks and to foresee new import routes for increasing amounts of oil and gas.

  6. Modelling Pan European Energy Scenarios in the NEEDS Project Overall objective of the project: To evaluate the full costs and benefits (i.e. direct + external) of energy policies and of future energy systems, both at the level of individual countries and for the enlarged EU as a whole. RS2a Objectives: • Generate the energy models of 28 EU countries, linked by energy and emissions trades that constitute the basis of the multi-region NEEDS Pan EU model. • Integrate LCA and Externalities into the NEEDS Pan EU model. • Define a baseline and a selection of policy scenariosto assess key energy and environment issues in Europe

  8. Main features of the NEEDS-TIMES models • Long term time horizon (2000-2050, by 5-year step), to take into account different standards of energy devices and technologies development • high technological detail, in energy supply and end-use sectors • full representation of all energy vectors included in the detailed energy balances • break down of demands for energy services Schematic representation of the Reference Energy System (Source: M. Blesl, IER – University of Stuttgart)

  9. The NEEDS Pan EU Model Structure (Source: IER)

  10. The NEEDS TIMES models • evaluation of policies at technology level both on country level and EU wide perspective • capability of analysing the impacts of different policies and price mechanisms (such as different tax or subsidy schemes for commodities and technologies) • capability of evaluating the expected long-term results of LCA • scenario analysis The Pan-EU model is more than the sum of the 28 national models as it allows to impose constraints at the European level that “coordinate” policies across borders. The model allows both Pan-EU policy evaluation together with the analysis of fragmented national policies and it is thus appropriate in evaluating the benefits of cooperation.

  11. The Scenarios for the Pan-EU model Reference scenario (Baseline): • all exogenous assumptions around drivers, energy prices and policies follow a BAU trend (GEM-E3 model). • macroeconomic and energy price background assumptions are in line with the latest DG TREN projections. • no specific climate policies such as to allow a proper evaluation of Kyoto and post Kyoto targets. • country decisions implemented for nuclear . Policy scenarios: • Environmental issues linked to energy use • A Post-Kyoto climate policyto stabilize CO2 concentrations below 450 ppmv following the EU COM (2007)2 • Air Quality Policies • Energy policies aiming at reducing the EU-dependency on energy imports • Enhancement of endogenous energy resources

  12. Enhancement of endogenous energy resources Reduce import dependence on oil and gasby introducing constraintson imports as fraction of primary energy use. This will increase the use of • renewables, energy efficiency and conservation, • biomass for bio-fuels and eventually hydrogen production • advanced nuclear for those countries they want to keep this option Based on conclusions, propose standards on renewables and efficiency and make recommendations for the use of nuclear energy. Identify for EU the importance of “Strategic partnerships” for oil and gas imports and propose policy options for “Strategic reserves”

  13. Some Results • Multi country runs: the NEEDS Pan- European model preliminary results • Enhancements of endogenous resources: The Italy case study.

  30. Trade-off curve: Natural gas increase of the total discounted system cost: 1% Import of gas -30% -20% -10% Natural gas cost: 3.84 kEuro/PJ (2005)

  31. Trade off curves: oil 7% increase of the total discounted system cost Import of oil -20% -10% Oil cost: 6.51 kEuro/PJ (2005)

  32. Primary energy consumption by scenario Oil Natural gas Natural gas • Natural gas consumption increases in OIL20 and Damage • Oil is substituted by natural gas when damage costs are considered • Renewable (including waste) consumption increase when fossil fuels use is constrained (OIL15_GAS20 scenario) Renewable

  33. Net imports by scenario Natural gas • natural gas import increases in OIL_20 and DAMAGE Oil • the introduction of damage factor determines a reduction of oil import but seems to have no effect on gas imports

  34. Emissions PM10 emissions • PM10 emissions decrease considering the damage factors (DAMAGE scenario) • CO2 emissions decrease only decreasing the fossil fuel consumptions (OIL15_GAS20 scenario) • The optimisation of consumption in the BAU scenario allows decreasing both the emissions of PM10 and CO2. CO2 emissions

  35. Conclusions The results shown are far from providing unquestionable solutions but should be regarded as a first step toward the implementation of the integration process, pointing out the main problems to be faced with. It is necessary to: • consider different scenarios of fossil fuels prices evolution. • examine in more details the different sectors, providing a quite large portfolio of technologies by sectors to obtain cost- effective solutions. • agree on data and assumptions, among the different methodologies, in order to set up interchangeable harmonized sets of data and produce coherent results • Perform a sensitivity analysis of results. Social acceptability is a fundamental parameter that should be considered for deriving and implementing the policy measures.

  36. Conclusions The NEEDS – TIMES modeling framework constitutes a powerful tool for comprehensive quantitative analyses and modeling internalization strategies, that allows to integrate into an unique modeling platform inputs coming from other methodologies (in particular LCA and ExternE) and is suited to support the formulation of long-term energy, environmental and economic policies both at national and Pan-European level. It is nevertheless necessary to harmonize the data input and outputs among the different methodologies in order to perform convergent iterative evaluation that could improve the response of each of them. The nature of models, the large uncertainties of the data and the changing boundary conditions lead to a continuous update of data and software, so that the results should be even regarded as the “best possible” with the available data and the considered boundary conditions.

  37. Work in progress …… Revision of the assumptions regarding technology characterisation and damage costs Statistical comparison of country results – BAU Scenario (Multivariate Data Analysis techniques are being applied, cluster analysis is in progress) Integration of updated generalised damage factors and LCA data in the Pan EU model Scenario analysis at Pan EU level with focus on key energy-environmental policy issues Thank you for your attention!

  39. The scenarios: final configuration • Reference BAU Scenario (Baseline) which basic assumptions were adapted to the latest DGTREN projections. For nuclear the country decisions have been implemented. • Post-Kyoto climate policy to stabilize CO2 concentrations below 450 ppmv following the EU COM (2007)2 (one scenario without variants) with the Kyoto climate policy implemented. • Enhancement of endogenous energy resources, (constraining imports of fossil fuels to foster the use of renewables, efficiency standards and new nuclear) • Improvement of environmental quality by indigenizing externalities related to local air pollution (i.e., w/o global externalities)

  40. Scenario variants Two variants could be investigated: A crisis scenario under moderate economic growth and pessimistic technological change assumptions to check for robust but conservative technological options. A case of improved environmental quality by endogenizing externalitiesrelated to local air pollution and global externalities to assess synergies.
