Experts point out that the cleanest electric generation goes through gas – La Provincia

Experts point out that the cleanest electric generation goes through gas - La Provincia


The commission of experts created by the previous central government of the PP to define the future of energy in Spain concludes that the greatest reduction of emissions of harmful gases to the atmosphere and costs for the electrical system in the Canary Islands will be achieved with the integration of gas . Specifically, 2.82 million tons of carbon dioxide (CO2) will be produced less per year and the savings for the system will reach 48%.

The Committee of Experts on Energy Transition Scenarios was created in July of last year. Nine months later he gave the then Minister of Energy, Álvaro Nadal, his conclusions. The members of the group were proposed by the Government, various political parties and social agents.

The assignment they had was to analyze different assumptions to mark the way forward in order to achieve the commitments to reduce polluting gases acquired within the European Union (EU). In addition, the study and the presentation of "specific alternatives for the energy transition in isolated systems, especially in insular systems based on their differential characteristics, were expressly indicated."

Always taking as horizon the year 2030, for when the emissions must have been reduced by 40% compared to 1990, they described five scenarios in the Canary Islands. The first one, which they called "base", contemplates that a large part of thermal generation is maintained, for which adjustments will have to be made in order to comply with the European Industrial Emissions Directive. Regarding the installed power in renewable sources (33% of the total), it describes an advance of wind energy from the 224 megawatts it had at the time of preparing the document to 1,015 megawatts in twelve years.

In addition, it considers the Lanzarote-Fuerteventura and Tenerife-La Gomera interconnections as well as the Chira-Soria pumping station operational. In terms of generation, diesel continues to be the main protagonist (38%) while 23% of the demand would be met with clean sources. With this structure, CO2 emissions reach 5.9 million tons per year and the cost of producing the electric power needed to meet the needs of families and businesses reaches 2,042 million euros, with the megawatt hour located at 169 euros

From there, the experts describe other assumptions with better results until they end up in the one that they denominate like "high renewable scenario with reinforcement of electrical and gas infrastructures". In this case, the power of renewable energies installed rises to 2,522 megawatts, more than double that of the base scenario. In addition, it includes "all reinforcements of links between islands", including Gran Canaria-Tenerife, "pumping units and regasification infrastructures, gas pipelines and adaptations of combined cycle power plants".

With these wickers, practically half of the power generation (49%) will be able to be met with renewables, while the presence of fuel and diesel in themixenergy falls to 19%, and gas reaches 32%. Thus, the CO2 released into the atmosphere drops by 2.82 million tons and the variable cost of generation remains at 1.065 million euros.
