Øylandene Mauritius og Barbados har begge begynt anskaffelsesprosesser for fornybar energi som involverer energilagring.
I likhet med andre øyregioner rundt om i verden, er begge landene avhengige av å importere fossilt brensel til store kostnader for å dekke energibehovet, og har sett energilagring sammen med fornybare energikilder, spesielt solenergi, 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 inviterte lukkede bud fra potensielle budgivere. The board plans to sign agreements for purchasing between 90MW to 110MW electricity.
En modell for energiforsynings- og kjøpsavtale (ESPA) forventes å gjøres tilgjengelig for budgivere innen en måned etter at RfP åpner, og budgivere har frist til 22. juni 2022 til å legge inn 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 bygde de første batterisystemene i nettskala- i Mauritius i 2018, med støtte fra det multilaterale Green Climate Fund (GCF), som til dags dato har støttet milliarder av dollar i prosjekter i 150 land.
In Mauritius, the GCF part-funded the battery systems as part of a raft of measures to akselerere utviklingen av-lavkarbonenergi 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-prosjektet, delt inn i tre 4MW-plasser og ett 2MW-nettsted, krevde et budsjett på rundt 10 millioner US-dollar for å fullføre. Siemens Frankrike leverte BESS, som brukes til tilleggstjenester for frekvensregulering.
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.
Importert fossilt brensel skader øyas økonomi samtidig som det forurenser
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 tilbyr en syv måneders kontrakt for konsulenttjenester med et estimert budsjett på 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.
Ved omleggingen av energisektoren vil det offentlige energi- og næringsutviklingsdepartementet ha behov for å anskaffe store kapasiteter fornybar energi, derav behovet for et rammeverk.
