Optimization for 2050 based on 2018 with 90% emission reduction

Overview

This document includes assumptions, results and interactive figures about the optimization for the Spanish energy mix in 2050 considering 2018 data with a 90% of emission reduction.

Main assumptions for 2050 electric mix

  • Shut down of coal power plants.
  • Shut down of nuclear power plants.
  • Cogeneration power reduced from 5.74 GW (2018) to 0.57 GW (2050), a 90% reduction.
  • Fuel & gas power reduced form 2.49 GW (2018) to 0.25 GW (2050), a 90% reduction.
  • New solar thermal power plants have 12-hour thermal storage capacity with a 90% of storage efficiency.
  • Pumped hydropower increased from 3.3 GW (2018) to 10 GW (2050).
  • Pumped hydropower capacity increased from 14 GWh (2018) to 42.4 GWh (2040) with a 76% of storage efficiency.
  • Electric batteries with 10 GW of power and 40 GW of capacity.
  • 0.5% annual demand increment from 2018 to 2030 and 1.5% from 2030 to 2050.
  • 90% emission reduction with respect to 1990.


Main results

Installed power PV (GW) Installed power wind (GW) Installed power CSP (GW) Total installed power (GW) Renewable power (GW) Mean energy cost (c€/kWh)
64.12 97.88 24.06 251.72 224.13 (89.04%) 4.52

Demand (TWh) Generated elec. (TWh) Exported elec. (TWh) Imported elec. (TWh) Dumped elec. (TWh) CO2 emissions (kton) and reduction (%) (1)
316.55 425.4 -43.84 0.11 65.12 6,437.53 (90.03 %)

(1) Percentage reduction with respect to emissions in 1990 (64,538 kton CO2).

Optimization Variables

New power of the following energy sources to be installed:

  • Photovoltaic power (PV).
  • Wind power.
  • Concentrating solar power (CSP).


Optimization Goals

Minimize the following criteria:

  • Average electricity generation cost.
  • Dumped energy.


Optimization Restrictions

  • Electric demand must be at least matched.
  • Combined cycle power plants are used as much as possible but without exceeding the maximum allowed CO2 emissions.
