Financial, Market, and Climate Analysis Regarding a Transition from Coal in Mauritius
Biomass power generation is an attractive option for the Mauritian island grid because it offers dispatchable generation, uses agricultural waste as fuel, and has lower emissions than fossil fuel technologies. The climate rationale to transition the Omnicane Independent Power Producer (IPP) to 100% biomass is even stronger because it will displace CO2-intensive coal generation with local or imported biomass generation.
Despite its benefits, biomass power generation projects are risky and could be unpopular. One of the main risks is feedstock supply. Biomass supply can present significant seasonal variations, which, combined with storage limitations, can lead to significant supply-demand imbalances. Biomass can also have significant year-to-year supply variations due to variability in yield from biomass harvesting operations or reductions in cultivated land. Furthermore, biomass projects can be controversial and elicit local criticism.
IFC is aware of these types of risks and concerns about biomass and the Omnicane project and wants to commission this high-level study to analyze the financial, economic, and climate implications of transitioning the Omnicane IPP to 100% biomass. The results of the study should show, with data and objective analysis, if this transition is a better economic and climate choice than continuing with the current biomass-coal operation or developing another technology that is dispatchable and has low carbon emissions.
The K&M team will estimate the levelized cost of electricity (LCOE) for the Omnicane power plant when burning biomass (sugar cane bagasse) and coal, as well as only biomass. In addition, K&M will seek to understand the biomass supply chain risks and mitigation options. K&M will then identify a shortlist of realistic dispatchable alternatives to the 100% biomass Omnicane IPP and to develop an estimate of the LCOE of these alternatives. To complete this work, K&M will develop an LCOE model to estimate the LCOE and CO2 emissions cost of all generation possibilities, including:
- Existing plant – bagasse + coal
- 100% biomass plant – local bagasse
- 100% biomass plant – imported biomass
- 100% biomass plant – mix of local bagasse and imported biomass
- Each of the alternative options identified and analyzed
In addition to these scenarios, K&M will run sensitivities on the power plant’s capacity factor, including 55%, 70%, and 90%.
Aqualectra is facing increased load growth and has recently retired its gas turbine unit, GT2, making it difficult for Aqualectra to meet peak demand. As a result, Aqualectra is requesting proposals for temporary power solutions to meet the growing demand in 2024 and 2025. The contract for temporary power would last approximately two years, starting around May 2024. Aqualectra requested K&M’s commercial and technical advisory services to determine the least-cost configuration of capacity and electricity from the temporary power units generating assets and the CRU gas turbine.
K&M discussed the scenarios and sensitivities that would be most informative to analyze with Aqualectra. Using the agreed-upon scenarios, K&M adapted its existing generation and cost models for Aqualectra to perform the temporary power analysis. K&M ran and analyzed the models and presented the results, including the levelized cost of electricity (LCOE) of the temporary power scenarios, the recommended configuration of the temporary power, the hourly dispatch of the generation assets, and all assumptions used in the analysis.
Fogging System Analysis
SEPCO has indicated the power grid in Jordan has had difficulty covering peak loads observed during high-temperature periods. As a result, SEPCO has reviewed potential solutions for its Samra Power Plant to increase power plant generation during these peak periods.
SEPCO intent is to modify all seven gas turbines installed at the Samra Power Plant by installing a fogging system in the gas turbine inlet. This modification aims to increase plant power generation to help the power grid cover the peak loads during high-temperature periods. To evaluate the technical and commercial viability of the fogging system installation, SEPCO engaged K&M Advisors to review the design of generating units’ and auxiliary equipment and systems to evaluate their ability to support the increased power output during fogging system operation.
The purpose of this study is to:
- Verify whether existing auxiliary equipment of each of the phases is capable of supporting facility operation with the fogging systems, and
- Determine the demineralized water demand required for the fogging system.
Fogging System RFP Development
Once the technical viability of implementing the fogging system has been confirmed, SEPCO will need to develop an RFP for suppliers to submit their proposal for design that meets the requirements of applicable standards and good engineering practice. K&M will develop the RFP documentation for suppliers to ensure that the design of the system is adequate and technically sound.
Fogging System Analysis
K&M developed GateCycle models of combined cycle plants to calculate heat and material balances for different ambient temperatures without and with the fogging system. For each combination of the ambient temperature and fogging system status, K&M developed a spreadsheet summarizing the system power output and power output increase, heat rate and heat rate change, fogging system evaporation rate/demineralized water requirements, and other steam and water impacting operation of HRSG, steam turbine, ACC, and other auxiliary equipment that could be impacted by the fogging system. To analyze the demineralized system requirements, K&M calculated the fogging system demineralized water requirements and the total daily demineralized water demand and compared it with the demineralized water system capacity. We evaluated whether there is a deficit of demineralized water with fogging system operation and suggested the required additional demineralized water system capacity.
Fogging System RFP Development
K&M will assist SEPCO in developing the fogging system RFP. The RFP document prepared by K&M will include instructions to bidders, functional technical specification including the scope of supply and services and general technical requirements, and forms to be submitted by bidders. It is expected that the draft supply contract will be prepared to be included in the RFP will be based on the standard SEPCO’s supply contract, so no draft contract preparation is included in K&M’s scope. SEPCO will provide K&M with any available technical and commercial information received to date from the prospective fogging system suppliers.
In accordance with the provisions of Article 15.1 of the BirAllah Exploration and Production Contract between bp and the Ministry of Petroleum, Mines and Energy of Mauritania (MPME), a collaborative examination must be carried out by the MPME and bp. The purpose of this examination is to evaluate the local natural gas (gas) outlets and the associated infrastructure for Mauritania’s possible domestic gas market.
The MPME made a formal request for phase 1 considerations of the BirAllah gas development project (the “BirAllah Project”), specifically for a supply of 105 million standard cubic feet per day (MMscfd) intended for the local market. A segment of this gas is planned to be transported to a 500 MW power plant, which is slated for construction in the Ndiago region, the same area where the onshore facilities of the BirAllah Project are proposed to be established.
K&M Advisors (“K&M”) was engaged by bp to conduct the evaluation subsequently referred to as the Joint Gas Market Study for the BirAllah Project (the “Study”). This evaluation will utilize the Mauritanian Gas Master Plan (the “Gas Master Plan”), previously conducted by EPCM, as part of the foundational framework. The primary objective of the Study is to reevaluate the local and international gas outlets in alignment with the resources made available by the BirAllah and GTA projects, before outlining a roadmap and assessing the impact of the BirAllah Project implementation.
The primary objectives of this work are to (i) provide an assessment of the feasibility and volumes of BirAllah gas that could be supplied to domestic power generation and mining demand as potential outlets, (ii) to present an assessment of other potential outlets to determine feasibility and their suitability to be supplied by BirAllah gas or otherwise, and (iii) to provide an initial overview of aspects of the global LNG market relevant for the potential to export BirAllah gas internationally. As part of the scope, K&M reviewed the following potential outlets:
- Power Sector:
- Use Gas Master Plan and other sources to understand expected role of 500MW power plant
- Analyze historic electricity demand and supply balance, types and costs of existing generation plants, and demand and supply forecast for the next 20 years—using data provided by the client, including size and timing of gas-fired capacity additions that are economically justified
- Use inputs from analysis to determine dispatch and volumes (quantity) of gas needed for 500 MW power plant
- Determine the major facilities necessary to supply gas to new gas-fired power plants for these sales, including pipelines, transmission lines, etc. This will include a high level analysis of interconnection options and cost estimates (CAPEX) for major components.
- Estimate cost of delivered gas to the end users broken down by component (as feasible), and levelized cost of electricity. Client to provide cost of delivered and treated gas onshore (in $/MMBtu), to be treated as a key input.
- Develop high level implementation schedule
- Gas to Mining:
- Determine the potential demand from existing mining operations (including for power generation and substituting diesel for LNG as fuel for mining hauling trucks).
- Identify location, fuel consumption, type of fuel used, and type of fuel-consuming equipment for a select group of the largest mines in the country—using data provided by the client
- Identify the least-cost logistics solution to deliver gas/LNG to each mine and estimate the cost of converting to gas existing equipment and gas demand after conversion
- Compare the cost of delivered gas to the cost of existing fuel and aggregate gas demand for those mines with a cost of gas below the cost of existing fuel.
- Develop high level implementation schedule
- Gas for Transport:
- Estimate existing fuel demand for different types of marine and road transport (trucks, buses, cars, etc.)—using data to be supplied by the client
- Using CNG penetration rates in other emerging markets with indigenous gas resources, estimate the gas demand required to supply a potential CNG market in Mauritania
- Using CNG distribution costs and the cost of converting vehicles to CNG, estimate the total cost of ownership of CNG -operated vehicles and compare to the cost with existing fuels
- Develop high level implementation schedule
- LPG and Condensate:
- Estimate existing LPG and condensate demand (location, volumes, types of uses)—using data provided by the client
- Identify other fuels/products that could be displaced if LPG or condensate were more widely available in Mauritania
- Perform high-level assessment of the infrastructure required to produce and distribute LPG and condensates
- Estimate the delivered cost of these two products and determine if they are competitive with existing LPG and Condensate prices in Mauritania and of the displaced fuels
- Develop high level implementation schedule
The study must consider, among the Mauritanian gas master plan outlets, those that are feasible with regard to the Bir Allah project (Gas to industries, Phosphate fertilizer, etc)
FortisTCI plans to increase the amount of electricity generated with solar PV that it uses to supply its customers in TCI. K&M has been engaged by FortisTCI to develop a robust estimate of the amount of electricity that can be generated with solar PV systems that are economically feasible in TCI. This will inform: (i) the targets FortisTCI sets for generating electricity with renewable energy (RE); and (ii) the energy and capacity FortisTCI will need from other sources, such as natural gas, to reliably meet the demand from its customers. As part of an initial assessment of solar PV on TCI, K&M will conduct a review of the existing GIS data and other relevant information, conduct site visits to Provo, North Caicos, Middle Caicos, South Caicos, Gran Turk, and Salt Cay, and will develop a dynamic financial model for solar PV. This will inform FortisTCI on the total amount of land available that can be used to install utility-scale solar PV systems, the total amount of electricity that can be generated with economically feasible solar PV systems, and the average levelized cost of electricity (LCOE) generated with economically feasible systems.
In this assignment, K&M holds several key responsibilities. Firstly, they are tasked with conducting a comprehensive review of the existing Geographic Information System (GIS) data and other pertinent information. Secondly, K&M is required to carry out site visits to multiple locations, including Provo, North Caicos, Middle Caicos, South Caicos, Gran Turk, and Salt Cay. Additionally, a pivotal aspect of their role is the development of a dynamic financial model tailored for solar photovoltaic (PV) systems. This model will serve to inform FortisTCI about crucial factors, such as the total available land for utility-scale solar PV installations, the potential electricity generation capacity of economically viable solar PV systems, and the average Levelized Cost of Electricity (LCOE) associated with electricity produced from these economically feasible systems. These responsibilities collectively contribute to the strategic planning and decision-making process regarding solar PV initiatives.
Utilities Aruba is undertaking several transformational initiatives to decarbonize the energy and water sectors in Aruba. These initiatives include a proposal to create a Hydrogen Valley where energy from a new solar PV facility would power the grid and produce green hydrogen for local uses and eventually for export. Green hydrogen would be used to power fuel-cells in buses, taxis, port and airport vehicles, hotels, and public buildings. The green hydrogen would also be blended with natural gas to power reciprocating engines that supply power to the grid.
K&M will conduct economic modeling of the solar PV plus green hydrogen project proposed to understand its impact on the energy cost to Arubans. K&M will also perform independent due diligence on the technology proposed. K&M will provide assistance exploring and applying for capital grants that could reduce the solar PV + green hydrogen project’s costs. The economic modeling work will also estimate the grant amounts required to make the cost of the green hydrogen project competitive with the alternative options.

The energy systems of Grenada, Saint Vincent and the Grenadines, Saint Lucia, Dominica, and Saint Kitts and Nevis are highly dependent on fossil fuels. Estimates and drilling results show these countries have 160 MW of geothermal energy production capacity. However, this capacity is significantly greater than the local demand. This situation provides opportunities to use the excess geothermal energy in creative ways that can promote the energy transformation in the Caribbean. Two examples are exporting the excess geothermal power to nearby islands or using it for electrolysis to create green hydrogen—a clean and versatile energy carrier. The Inter-American Development Bank hired K&M for this assignment to assess the potential synergies between excess geothermal energy production capacity not needed for local use in the Eastern Caribbean and the creation of a Caribbean-based green hydrogen market.
K&M carried out a pre-feasibility assessment for green hydrogen production from geothermal power and commercialization in the Eastern Caribbean (EC) with a focus on Grenada, Saint Vincent and the Grenadines, Saint Lucia, Dominica, and Saint Kitts and Nevis. This included an electricity sector analysis, estimation of geothermal energy potential, and conducting a geothermal energy cost analysis. K&M also estimated the demand for green hydrogen for energy, industrial use, heavy transport, and petrochemical production in the EC and Trinidad and Tobago.
Our team identified the export opportunities for green hydrogen produced in the EC, as well as the required technologies and options for the production and export of green hydrogen. Additionally, an inter-island hub for green hydrogen logistics and international export was determined. The team estimated the volume of green hydrogen produced from excess geothermal power in the EC, assessed the investment needs for green hydrogen production from geothermal sources, and calculated the levelized cost of green hydrogen.
Furthermore, a cost-benefit analysis was conducted comparing green hydrogen to subsea transmission and battery storage. These activities contributed to the development of a preliminary business model for a green hydrogen network in the EC. As part of this work, technical, commercial, and regulatory barriers for a regional green hydrogen market were identified, potential business models to support the market’s development were analyzed, contractual schemes to deliver green hydrogen to T&T were identified, and the range of pricing for green hydrogen offered to key regional and international markets from T&T was determined.
The Inter-American Development Bank had contracted a team of firms consisting of K&M, GeothermEx, and POWER Engineers to assess the potential uses of excess geothermal energy in the Eastern Caribbean. The general objective of this consultancy was to assess options for exporting excess geothermal energy in the Eastern Caribbean. The specific objectives of this consultancy were to carry out an infrastructure and investment assessment for green hydrogen production in the Eastern Caribbean based on geothermal energy generation, as well as develop a business model for a green hydrogen network in the region. K&M was responsible for estimating the volume of green hydrogen that could have been produced from excess geothermal power in the Eastern Caribbean, determining the investment needs to produce green hydrogen from geothermal sources, estimating the levelized cost of green hydrogen, and proposing a preliminary business model for a green hydrogen network in the Eastern Caribbean.
The general objective of this consultancy was to prepare the technical, economic, and legal feasibility studies for the introduction of green hydrogen in the energy supply for the domestic market, as well as the supply of an international market from Panama.
In this assignment, K&M was responsible for assessing the potential routes for commercializing green hydrogen from Panama, identifying the role of Panama in the green hydrogen supply chain, developing a methodology for prioritizing capital investments in green hydrogen, and carrying out the economic analysis and risk analysis of developing green hydrogen facilities in Panama.
