EFFICIENT USE OF WOOD RESOURCES ON THE POWER INDUSTRY OF LATVIA
The aim of the paper is to determine the potential of energy-efficiency in the production of the -wood resources. The beginning of the paper provides a short review of the existing situation as well as a list of main problems in wood resource usage in the power industry of Latvia. A special attention is paid to large amounts of fuelwood exports. The paper gives information on the potential of fuelwood and its distribution.The result of the research is the calculation ofpotential wood resource savings resulting from energy-efficiency increase activities in heat sources, heating mains and consumer systems, which are already run using fuelwood. As a result of energy-efficiency activities in the heat energy production process, it is possible to save up to even 4.2 million MWh of wood fuel.At the end, approximate calculations of emission savings in case of the utmost efficient wood usage have been carried out

Implementation of the Energy Efficiency Directive and the Impact on District Heating Regulation
Discussions in Latvia are ongoing regarding the
optimum solution to implementing Directive 2012/27/EU on
energy efficiency.
This study analyses a scenario where a significant fraction of
target energy efficiency is achieved by obliging energy utilities to
implement user-end energy efficiency measures. Investment
related costs are likely to be included in the energy prices and
service tariffs therefore gains for the users are under question.
The authors analyze ways to achieve a balance between user
gains from energy end-use savings and increased energy prices
and tariffs as a result of obligations imposed upon energy
utilities including the energy supply sectors where supply tariffs
are regulated.
Authors also have assessed the disadvantages of the current
Latvian district heating regulation and have marked the next
steps for a transition from hard regulation towards the
approximation of benchmarking and market principles
Simulation of Energy Development Scenarios in Latvia on Regional Level
Up to now the development scenarios of Latvian energy and fuel balance were mainly
designed for the national level. However in the regional level there are significant differences
both in energy consumption and fuel resources used. For the simulation and comparison of
different energy development scenarios, MESAP (Modular Energy System Analysis and
Planning) software, allowing making calculations at national and regional level without
changing the structure of the model, was used. To perform a detailed regional modelling,
Latvia was split in 6 regions, each having a separate forecasted electricity, thermal energy and
fuel final consumption. For the regional modelling, similar RES structure to overall Latvian
energy balance development options simulation was used. Three development scenarios in the
regional level have been simulated: base scenario (I), scenario of maximal use of renewable
energy resources and domestic energy resources (II) and maximum production of electrical
energy and fuel diversification scenario (III). The choice of scenarios can be substantiated
with a necessity to promote usage of renewable energy resources, as well as with decrease of
electricity imports proportion in the energy balance of Latvia. The simulation results show,
that the increasing demand of energy can be covered in several ways – by continuing to
import power, maximally using the renewable and local energy resources, as well as using
coal and biomass mix for the production of electricity
