(1) without LULUCF; compared to 2005;

(2) Reduction in primary energy consumption without non-energy uses. By comparison with the projections of the

2007 PRIMES model

(3) Electric interconnections

The comments of the

public consultation are

being analyzed and

integrated.

1. DECARBONIZATION OF NATIONAL ECONOMY

Ensure a path of reduction of national greenhouse gas emissions (GHG) in allsectors of activity, including energy and industry, mobility and transport,agriculture and forest and waste and wastewater, and promote the integration ofmitigation objectives in sectoral policies (mainstreaming).

2. PRIORITY TO ENERGY EFFICIENCY

Reduce primary energy consumption in several sectors in a context of

sustainability and cost effectiveness, focus on energy efficiency and efficient use

of resources, prioritizing the rehabilitation and renovation of the building, and

promote zero emission buildings.

5. PROMOTING SUSTAINABLE MOBILITY

Decarbonization of the transport sector, promoting modal shift and better

functioning of collective transport networks, promoting active and electric

mobility and the use of clean alternative fuels.

4. ENSURE SECURITY OF SUPPLY

Ensure the maintenance of a resilient and flexible system with diversification ofsources and origins of energy, reinforcing, modernizing and optimizing energyinfrastructures, developing interconnections and promoting the integration,reconfiguration and digitization of the energy market, maximizing its flexibility.

7. DEVELOPING AN INNOVATIVE AND COMPETITIVE INDUSTRY

Promote industrial modernization based on innovation, decarbonization,

digitalization (industry 4.0) and circularity, contributing to increase the

competitiveness of the economy.

8. ENSURE A FAIR, DEMOCRATIC AND COHESIVE TRANSITION

Promote the role of the citizen as an active agent in decarbonization and

energy transition, create equality conditions for all, fight energy poverty, create

instruments for the protection of vulnerable citizens and promote active citizen

involvement and territorial valorization.

3. REINFORCE THE BET ON RENEWABLE ENERGY AND ON REDUCING ENERGY DEPENDENCY

Increase diversification of energy sources through increased and sustainable useof endogenous resources, promoting increased electrification of the economyand encouraging R & D & I in “clean technologies”.

6. PROMOTING SUSTAINABLE AGRICULTURE AND CARBON SINK

Reduce the carbon intensity of agricultural practices and promote effective

agroforest management by helping to increase natural sink capacity.

PV production sites in Portugal including:

- In production

- Licensed

- In request

- In project

More than 400 sites are occupied or are expected to be

occupied with photovoltaic solar power plants

Where are so lar power p lants located or p lanned in Por tuga l?

Solar Installed capacity in

Portugal:

It is in the south and center of the

country, especially in the Algarve and

Alentejo, that the potential for solar

projects lies

20

With the publication of Decree-Law 76/2019, amending Decree-Law 172/2006, are changed

the rules of access to a scarce resource, the availability of power reception by the Public

Service Electric Network (RESP)

Capacity requests are now secured through a Title of power receiving reservation in RESP,

with the respective operator, or by a competitive procedure which this Tender is an example.

The competitive procedure to put this capacity volume, allows also to increase the scale and

integration of various projects in the Public Network, bringing synergies that allow for

better planning of supply and optimization of network investments.

21

Allows the Administration to concentrate its activity on the procedures related to power

allocation requests that effectively have the Title.

The auction has other great advantages compared to the previous power allocation procedures:

It allows the comparison between two different systems: discounts offers to a reference

rate and, market price option with increasing offers for the costs of the network infrastructure.

The auction, as a competitive procedure par excellence, ensures a greater benefit for the

system and for the consumers, since it allows the imposition of conditions and technical

requirements that improve the quality of the solutions.

Solar forThermal Production

Solar energy case

(technology. vs. work temperature)

Different technologies for

different temperatures

ranges

Thermal solar technology catches the sun thermal energy and transfers it to an

heating fluid. In indirect systems the heat transfer fluid flows through an heat

exchanger and heats de process fluid.

- Heating represents today around 46% of Europe's energy

consumption, mainly at urban level

- Solar collectors normally suppress 60% to 80% of hot water

needs

- In Portugal, 2% of the final energy consumption in homes is

from solar thermal

- In Portugal, 2010 represented the beginning of Solar Thermal

market contraction, essentially due to the economic crisis

- In 2015 (last data) the installed accumulated capacity

reached 1.121.104 m2 (784.773 kWth)

- Solar thermal now growing due to construction boost

Possible measures to boost the Solar

Thermal in Portugal

- Implementing new policy measures

- Promoting information campaigns,

promoting a competitive Heat & Cooling

market

- Regulating the certification of installers

activity focusing on integrated solutions of

Heat and Cooling

- Investing in new applications as active

solar buildings, solar cooling, air conditioning

and solar heat for industrial processes

- Investing in R&D involving new materials
