Națiunile insulare Mauritius și Barbados au început ambele procese de achiziție de energie regenerabilă care implică stocarea energiei.
În comun cu alte regiuni insulare din întreaga lume, ambele țări se bazează pe importul de combustibili fosili la prețuri mari pentru a-și satisface cererea de energie și au văzut ca soluție stocarea energiei asociată cu sursele regenerabile, în special fotovoltaice solare.
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 a invitat oferte sigilate de la potențiali ofertanți. The board plans to sign agreements for purchasing between 90MW to 110MW electricity.
Un model de contract de furnizare și cumpărare de energie (ESPA) este de așteptat să fie pus la dispoziția ofertanților în termen de o lună de la deschiderea RfP, iar ofertanții au până la 22 iunie 2022 pentru a depune oferte.
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 a construit primele sisteme de baterii la scară{0}}grid în Mauritius în 2018, cu sprijin financiar din partea Fondului Verde pentru Climă (GCF), care a susținut până în prezent proiecte de miliarde de dolari în 150 de țări.
In Mauritius, the GCF part-funded the battery systems as part of a raft of measures to accelerează dezvoltarea energiei cu emisii reduse de carbon- 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.
Proiectul de 14 MW, împărțit în trei site-uri de 4 MW și unul de 2 MW, a necesitat un buget de aproximativ 10 milioane USD pentru finalizare. Siemens Franța a furnizat BESS, care este utilizat pentru serviciile auxiliare de reglare a frecvenței.
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.
Combustibilii fosili importați dăunează economiei insulei în timp ce poluează
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".
Oferă un contract de șapte luni pentru servicii de consultanță, cu un buget estimat de 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.
În tranziția sectorului energetic, Ministerul Guvernului Energiei și Dezvoltării Afacerilor va trebui să achiziționeze capacități mari de energie regenerabilă, de unde trebuie să existe un cadru.
