Ø-nationerne Mauritius og Barbados har begge påbegyndt indkøbsprocesser for vedvarende energi, der involverer energilagring.
I lighed med andre ø-regioner rundt om i verden er begge lande afhængige af at importere fossile brændstoffer til store omkostninger for at imødekomme deres energibehov og har set energilagring parret med vedvarende energi, især solcelleanlæg, som en løsning.
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 inviterede lukkede bud fra potentielle budgivere. The board plans to sign agreements for purchasing between 90MW to 110MW electricity.
En model for energiforsyning og købsaftale (ESPA) forventes at blive stillet til rådighed for tilbudsgivere inden for en måned efter RfP's åbning, og tilbudsgivere har indtil den 22. juni 2022 til at afgive bud.
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 byggede de første netbaserede batterisystemer- i Mauritius i 2018 med støtte fra den multilaterale Green Climate Fund (GCF), som til dato har støttet milliarder af dollars i projekter i 150 lande.
In Mauritius, the GCF part-funded the battery systems as part of a raft of measures to fremskynde udviklingen af-kulstoffattig energi 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.
14MW-projektet, opdelt i tre 4MW-anlæg og et 2MW-anlæg, krævede et budget på omkring 10 mio. Siemens Frankrig leverede BESS, som bliver brugt til frekvensregulering af hjælpetjenester.
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.
Importerede fossile brændstoffer skader øens økonomi, mens de forurener
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".
Det tilbyder en syv måneders kontrakt for konsulenttjenester med et anslået budget på 200 USD,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.
Ved omstillingen af energisektoren vil regeringens Ministerium for Energi og Erhvervsudvikling være nødt til at indkøbe store kapaciteter af vedvarende energi, hvorfor der er behov for, at der er rammer.
