In recent years, the dependency rate of Belgium in terms of energy imports decreased. Since 2016, the primary energy consumption in Belgium, which includes the transformation output, has been rather stable. While the gross inland consumption, which does not cover transformation output, decreased slightly from 2006 to 2017. In other words, although data could suggest a decline, energy demand in Belgium has not changed much in recent years. In 2017, the total energy tax revenues in Belgium amounted to 6.4 billion euros.
In comparison to other countries, electricity prices in Belgium were rather steep. In January 2020, the consumer price index for energy amounted to 110.56, although this index also includes housing and water. In February 2020, the inflation of the consumer price index amounted to -1,87 percent. Such an inflation indicates that energy prices for consumers have changed slower than in the previous months.
In 2019, Engie Electrabel held the highest market share in the country for electricity and natural gas. In the Brussels-Capital Region, this company notably held 64 percent of the electricity supplier market and 63 percent of the natural gas supplier market. In Belgium, natural gas consumption peaked at 19.8 billion cubic meters in 2010. While it fell as low as 14.4 billion cubic meters in 2014, since then, natural gas consumption increased gradually in Belgium.
As of June 2019, Belgium had seven nuclear reactor plants and could produce roughly 6 Gigawatts of nuclear power per year. For instance, the country consumed 1.1 percent of nuclear energy worldwide in 2018. Although the share of electricity produced by nuclear plants in Belgium reached 40 percent in 2018, since 2016, the nuclear share decreased. In 2018, Belgium had double the nuclear share in electrical supply than the Unites-States, yet was far behind its French neighbors.
Over the last decade, the renewable energy capacity grew in Belgium. The share of consumed renewable energy reached 9 percent in 2018. For instance, the primary energy produced from biogas increased steadily over the last decade. The onshore wind energy capacity also expanded. In 2018, Belgium had 309 offshore wind capacity installations spread across seven offshore wind farms. During this time, Belgium also had the second-highest solar photovoltaic capacity per inhabitant in Europe. From 2013 to 2018, the Belgian solar photovoltaic capacity per inhabitant increased over time alongside with an increase of its installed and connected capacity. Unsurprisingly, the volume of electricity generated by solar photovoltaics in Belgium steadily expanded during this period.
