De eilandstaten Mauritius en Barbados zijn beide begonnen met inkoopprocessen voor hernieuwbare energie waarbij energie wordt opgeslagen.
Net als andere eilandregio's over de hele wereld, zijn beide landen afhankelijk van het importeren van fossiele brandstoffen tegen hoge kosten om aan hun energievraag te voldoen en hebben ze energieopslag in combinatie met hernieuwbare energiebronnen, met name zonne-PV, als een oplossing gezien.
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 uitgenodigde verzegelde biedingen van potentiële bieders. The board plans to sign agreements for purchasing between 90MW to 110MW electricity.
Een model energieleverings- en koopovereenkomst (ESPA) zal naar verwachting binnen een maand na de opening van de RfP aan bieders beschikbaar worden gesteld en bieders hebben tot 22 juni 2022 om biedingen in te dienen.
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 bouwde in 2018 de eerste batterijsystemen op grid-schaal op Mauritius, met financiële steun van het multilaterale Green Climate Fund (GCF), dat tot nu toe miljarden dollars aan projecten in 150 landen heeft ondersteund.
In Mauritius, the GCF part-funded the battery systems as part of a raft of measures to versnellen van de ontwikkeling van -koolstofarme energie 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.
Het 14MW-project, opgesplitst in drie 4MW-sites en één 2MW-site, vergde een budget van ongeveer US10 miljoen om te voltooien. Siemens Frankrijk heeft de BESS geleverd, die wordt gebruikt voor ondersteunende diensten op het gebied van frequentieregeling.
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.

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".
Het biedt een contract van zeven maanden voor adviesdiensten met een geschat budget van 200 dollar,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.
Bij de transitie van de energiesector zal het ministerie van Energie en Bedrijfsontwikkeling grote capaciteiten aan hernieuwbare energie moeten aanschaffen, vandaar de noodzaak van een kader.
