Cov Islands tuaj Mauritius thiab Barbados ob leeg tau pib cov txheej txheem kev siv hluav taws xob txuas ntxiv uas suav nrog kev cia lub zog.
Nyob rau hauv sib piv nrog rau lwm cov kob nyob ib ncig ntawm lub ntiaj teb no, ob lub teb chaws cia siab rau importing fossil fuels ntawm tus nqi zoo kom tau raws li lawv lub zog xav tau thiab tau pom lub zog cia ua ke nrog renewables, tshwj xeeb tshaj yog hnub ci PV, raws li ib tug daws.
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 caw cov ntawv sib tw los ntawm cov neeg sib tw yav tom ntej. The board plans to sign agreements for purchasing between 90MW to 110MW electricity.
Ib qho qauv siv hluav taws xob thiab kev cog lus yuav khoom (ESPA) yuav tsum muaj rau cov neeg sib tw hauv ib hlis tom qab RfP qhib thiab cov neeg sib tw muaj txog 22 Lub Rau Hli 2022 kom xa cov ntawv sib tw.
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 tau tsim thawj daim phiaj- teev roj teeb hauv Mauritius hauv xyoo 2018, nrog kev txhawb nqa nyiaj txiag los ntawm ntau lub koom haum Green Climate Fund (GCF), uas yuav tsum tau txhawb nqa ntau txhiab daus las ntawm cov haujlwm hauv 150 lub tebchaws.
In Mauritius, the GCF part-funded the battery systems as part of a raft of measures to leeb txoj kev loj hlob ntawm tsawg- carbon zog 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.
Qhov project 14MW, muab faib ua peb qhov chaw 4MW thiab ib qhov chaw 2MW, xav tau kev siv nyiaj txog US10 lab los ua kom tiav. Siemens Fabkis tau muab BESS, uas yog siv rau kev tswj hwm kev pabcuam ntxiv.
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.
Imported fossil fuels ua phem rau cov kob kev lag luam thaum muaj kuab paug
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".
Nws tab tom muab ib daim ntawv cog lus xya lub hlis rau cov kev pab sab laj nrog kev kwv yees nyiaj txiag ntawm 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.
Hauv kev hloov pauv lub zog, tsoomfwv Ministry of Energy thiab Kev Txhim Kho Kev Lag Luam yuav xav tau kom muaj peev xwm loj ntawm lub zog tauj dua tshiab, yog li xav tau lub hauv paus ua haujlwm.
