“…Another major policy adaptation should allow the energy markets of SVG to open up further to incorporate the flexible and cost-effective provision of stored energy. A recent study by Chen et al (2020) argues that the increased injection of Battery Energy Storage Systems (BESSs) within the energy landscape of the Caribbean, such as Jamaica in their study, will create further opportunity of RE development, grid stabilization, and the overall reduction of energy prices under optimal scenarios of implementation. Battery technologies, in its various forms of chemistries and thermodynamics, have sharply dropped in recent years and will continue to see further competitiveness (though price bottoms exist that make certain technologies less competitive) as global markets respond to the increased supply of stored energy (Hsieh et al, 2019).…”

The energy security of each Caribbean Community (CARICOM) member state is a key issue specifically addressed based on the energy demands of each nation. St. Vincent and the Grenadines (SVG) has the potential to strengthen its energy sector through the exploitation of immense untapped natural geothermal resources. Currently, SVG is planning to integrate base load power through a 10 Megawatt-electric (MWe) geothermal power plant (GPP1). The paper aims to highlight a detailed resource assessment profile of the renewables across SVG and the projected benefits of the proposed 10 MWe geothermal power potential, such as the positive economic development (displacing 149,000 bbls of crude oil), and the transition to a more climate-sensitive nation (displacing an estimated 0.172 million tCO2e/year). In addition, a volumetric method (Monte Carlo simulations) has been applied to reveal that the geothermal reservoir can sustain a minimum of 31 MWe, 34 MWe and 92 MWe over the lifespan of 25–30 years, for well 1 (SVG01), well 2 (SVG02) and well 3 (SVG03) respectively. Given the findings of the assessment and simulations, several policy approaches are identified as potential means of enhancing geothermal resource development and leveraging the resource for the islands’ sustainable energy demands. These include incentivization for public-private partnerships, information certainty, regulatory processes, and strengthened institutions.

“…The variable nature of wind and solar power mandates that there be an additional source of energy or storage of energy to complement these two resources. Battery storage is an increasingly integrated option for storing energy whereby utilities operate load shifting methods to 'transfer' energy from times of plentiful sun and wind to those times without [18]. The other available avenue to complement variable renewable power generation is through the use of a dispatchable (controllable) source of power.…”

Many Caribbean island nations have historically been heavily dependent on imported fossil fuels for both power and transportation, while at the same time being at an enhanced risk from the impacts of climate change, although their emissions represent a very tiny fraction of the global total responsible for climate change. Small island developing states (SIDS) are among the leaders in advocating for the ambitious 1.5°C Paris Agreement target and the transition to 100% sustainable, renewable energy systems. In this work we present three central results. First, we show through GIS mapping of all Caribbean islands the potential for near-coastal deep-water as a resource for Ocean Thermal Energy Conversion (OTEC) and couple these results with an estimate of the countries for which OTEC would be most advantageous due to a lack of other dispatchable renewable power options. Second, hourly data have been utilized to explicitly show the trade-offs between battery storage needs and dispatchable renewable sources such as OTEC in 100% renewable electricity systems, both in technological and economic terms. Finally, the utility of near-shore, open-cycle OTEC with accompanying desalination is shown to enable a higher penetration of renewable energy and lead to lower system levelized costs than those of a conventional fossil fuel system.

“…With increasing attractiveness (technological evolvement and further declining cost) and growing share of intermittent renewable energy (IRE) sources (e.g. solar and wind) [1], challenges arise for balancing power systems adequately, i.e., to guarantee grid stability and power quality [2]. IRE comes with a burden to conventional ways of power generation, which has to be dealt with in a proper way, not only for the sake of optimal balancing, but also considering the additional stresses on power generation units because of altered operational schemes [3,4].…”

“…The challenge becomes greater for small (island-like) power systems with relative low grid inertia. While storage technologies present a promising solution for the future, the state-of-the-art may still come at a high cost, which limits the large-scale utilization at present [2,5]. Furthermore, storage system capabilities require careful consideration, since these may not always meet the requirements to properly manage conventional generation in turn [4].…”

REVUB-Light: A parsimonious model to assess power system balancing and flexibility for optimal intermittent renewable energy integration – A study of Suriname

A new model, REVUB-Light, an extended modelling approach for the recently developed "Renewable Energy Variability Upscaling and Balancing" (REVUB) model, is highlighted in this study for its relatively simple and effective parameterization for power balance optimization simulations, considering high Intermittent Renewable Energy integration. We demonstrate the effective use of the REVUB-Light model, considering a study for Suriname. The results for different cases are compared to those of the REVUB model, previously used for similar assessments for Suriname. Following distinct optimization procedures, our results confirm the REVUB model findings, i.e., a highly complementary role for wind energy, with up to 20e30% feed-in potential, based on the assumed (currently most probable) hydrological and wind regimes. The REVUB-Light model is validated based on actual operational data, enabling assessments of the potential real world response, and the benefits of flexible (optimized) operational regimes, underlining its potential for renewable energy modelling. It is further shown that Suriname has potential for (near) 100% renewable energy supply, for the mid-term horizon (2030), if additional hydropower potential is developed in combination with hydro-supported wind energy. Overall, the parsimonious approach of REVUB-Light proves to be a reliable modelling tool, and facilitates general usability by "nonexperts" such as policymakers.
