Le nazioni insulari Mauritius e Barbados hanno entrambe avviato processi di approvvigionamento di energia rinnovabile che coinvolgono lo stoccaggio di energia.
In comune con altre regioni insulari del mondo, entrambi i paesi fanno affidamento sull'importazione di combustibili fossili a costi elevati per soddisfare la loro domanda di energia e hanno visto come soluzione lo stoccaggio dell'energia abbinato alle energie rinnovabili, in particolare il solare fotovoltaico.
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 ha invitato offerte sigillate da potenziali offerenti. The board plans to sign agreements for purchasing between 90MW to 110MW electricity.
Un modello di contratto di fornitura e acquisto di energia (ESPA) dovrebbe essere messo a disposizione degli offerenti entro un mese dall'apertura della RfP e gli offerenti hanno tempo fino al 22 giugno 2022 per presentare le offerte.
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 ha costruito il primo sistema di batterie su scala{0}}a rete a Mauritius nel 2018, con il sostegno finanziario del Green Climate Fund (GCF) multilaterale, che fino ad oggi ha sostenuto progetti per miliardi di dollari in 150 paesi.
In Mauritius, the GCF part-funded the battery systems as part of a raft of measures to accelerare lo sviluppo di energia a basse-anidride carbonica 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.
Il progetto da 14 MW, suddiviso in tre siti da 4 MW e un sito da 2 MW, ha richiesto un budget di circa 10 milioni di dollari per essere completato. Siemens France ha fornito il BESS, che viene utilizzato per i servizi ausiliari di regolazione della frequenza.
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.
I combustibili fossili importati danneggiano l'economia dell'isola mentre inquinano
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".
Offre un contratto di sette mesi per servizi di consulenza con un budget stimato di 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.
Nella transizione del settore energetico, il ministero dell'Energia e dello sviluppo delle imprese del governo dovrà procurarsi grandi capacità di energia rinnovabile, da qui la necessità di un quadro di riferimento.
