Las naciones insulares de Mauricio y Barbados han iniciado procesos de adquisición de energía renovable que implican el almacenamiento de energía.
Al igual que otras regiones insulares de todo el mundo, ambos países dependen de la importación de combustibles fósiles a un gran costo para satisfacer su demanda de energía y han visto el almacenamiento de energía junto con las energías renovables, en particular la energía solar fotovoltaica, como una solución.
The Central Electricity Board (CEB) of Mauritius in East Africa issued a request for proposal (RfP) last week for the purchase of electricity from hybrid renewable energy facilities, defined in this instance as solar PV-plus-battery storage.
The CEB, a government-owned and operated power generation and distribution agency, has ofertas selladas invitadas de posibles postores. The board plans to sign agreements for purchasing between 90MW to 110MW electricity.
Se espera que un acuerdo modelo de suministro y compra de energía (ESPA) esté disponible para los postores dentro de un mes después de la apertura de la RfP y los postores tienen hasta el 22 de junio de 2022 para presentar sus ofertas.
Also advertising for international bidding a few days ago was another CEB RfP for purchase of electricity from small scale renewable energy hybrid facilities, this time seeking to procure 30MW to 50MW.
CEB construyó los primeros sistemas de baterías a escala de red-en Mauricio en 2018, con el apoyo financiero del Fondo Verde para el Clima (GCF, por sus siglas en inglés) multilateral, que hasta la fecha ha apoyado miles de millones de dólares en proyectos en 150 países.
In Mauritius, the GCF part-funded the battery systems as part of a raft of measures to acelerar el desarrollo de energía baja-en carbono in the country, which meets 84 percent of its primary energy requirements with imported fossil fuels.
Coal and fuel oil imports in particular have been feeding rising greenhouse gas emissions (GHGs) but the country it targeting for renewable energy to provide 35 percent of its energy demand by 2025 and then 60 percent by 2030.
After that first pair, which were each of 2MW power output and 1.12MWh capacity and built at two substations, a 14MW battery energy storage system (BESS) project split across four CEB substations was commissioned through the GCF programme late last year, also supported by the United Nations Development Programme.
El proyecto de 14MW, dividido en tres sitios de 4MW y un sitio de 2MW, requirió un presupuesto de alrededor de US$10 millones para completarse. Siemens Francia suministró el BESS, que se utiliza para servicios auxiliares de regulación de frecuencia.
CEB general manager Jean Donat said at the time that project was inaugurated that the era of renewable energy optimisation "is well on the way," in Mauritius, with the board having integrated more than 100MW of solar PV into the grid by then.
The country's government said in 2020 that it was committing funds to increase battery deployments to 40MW in a 2021-2022 budget announcement.
Los combustibles fósiles importados dañan la economía de la isla mientras contaminan
Meanwhile the Caribbean island of Barbados is targeting 100 percent renewable energy use and carbon neutrality by 2030 and — as was the case with the UNDP's assessment of Mauritius — the government has described renewables with storage as a powerful way of democratising energy.
In seeking to create a framework for the procurement of renewable energy and/or energy storage, the Inter-American Development Bank (IDB) is hosting a competitive solicitation for consultancy services to help develop it.
Issued a few days ago, interested parties have until 4 April 2022 to respond. The project is called "Support for the Design of Carbon Neutral Strategies in the Context of Energy Transition in Barbados".
Está ofreciendo un contrato de siete meses para servicios de consultoría con un presupuesto estimado de US200,000.
According to the IDB's summary, the island, with 280,000 inhabitants, imports fossil fuels for over 90 percent of its energy needs and in 2018 its fuel import bill stood at US253 million. Only 5.5 percent of electricity sold in the country came from renewable sources, abut 3.5 percent from rooftop solar PV and 2 percent from its sole 10MW utility-owned solar farm.
As well as the high cost of fuel, the impact can be felt in damage to Barbados' natural habitat, which as an economy dependent on tourism also has a knock-on economic effect.
En la transición del sector energético, el Ministerio de Energía y Desarrollo Empresarial del gobierno deberá adquirir grandes capacidades de energía renovable, de ahí la necesidad de contar con un marco.
