“…2c). We explored the expansion of bioenergy generation for Ghana; however, as they become economically feasible in the coming decades, other measures such as batteries 46 , power-to-gas systems 47 and demand-side management 48 might support intermittent renewables integration with lower impacts because they do not depend on water resources to produce or store energy. We used bioenergy in our study because the Ghanaian authorities have identified it as the main renewable, dispatchable and spatially distributed technology available in the country, and it can use the residues from various stages of agricultural and forestry activities, mainly from crop harvesting, wood logging, and from municipal wastes and other commercial and domestic activities 37 .…”

Designing diversified renewable energy systems to balance multisector performance

Renewable energy system development and improved operation can mitigate climate change. In many regions, hydropower is called to counterbalance the temporal variability of intermittent renewables like solar and wind. However, using hydropower to integrate these renewables can affect aquatic ecosystems and increase cross-sectoral water conflicts. We develop and apply an artificial intelligence-assisted multisector design framework in Ghana, which shows how hydropower’s flexibility alone could enable expanding intermittent renewables by 38% but would increase sub-daily Volta River flow variability by up to 22 times compared to historical baseload hydropower operations. This would damage river ecosystems and reduce agricultural sector revenues by US$169 million per year. A diversified investment strategy identified using the proposed framework, including intermittent renewables, bioenergy, transmission lines and strategic hydropower re-operation could reduce sub-daily flow variability and enhance agricultural performance while meeting future national energy service goals and reducing CO2 emissions. The tool supports national climate planning instruments such as nationally determined contributions (NDCs) by steering towards diversified and efficient power systems and highlighting their sectoral and emission trade-offs and synergies.

“…Renewable Energy Technologies, particularly PVs, can reduce the country's dependence on centralized power from hydro and fossil fuel sources [101] . The existence of a regional integration network in the sub region and the increased electrification demand in some areas is a great opportunity in the development of the renewable energy resource.…”

Objective: Renewable energy policy is a framework used by governments or institutions to address problems related to renewable energy production, distribution, and consumption. The aim of this review is to explore into the goals, instruments and planned measures of the Government of Ghana in the renewable energy resources field.Methods: Methodologically, the review focused and based its findings on the overview and analysis of laws and regulations and other official documents used by Ghanaian Government. Rapid review method was used in evaluation of what is already known concerning the policy and assessing critically current researches through systematic review methods. Results:The results of the study revealed that progress has been made in renewable energy resources sector recently. The midterm targets for the proportion of renewable energy out of the overall energy consumption has been defined; input tariff have been adopted; legislative and socio-economic barriers of increased exploitation for renewable energy resources have been analysed and measures and activities suggested for effective resolution. The outcome of the review revealed that existing renewable energy resources related legislation is imprecise and incomplete. Several bylaws, standards and guidelines are still outstanding. The key renewable energy related documents are also inconsistent, lack clarity and are inaccurately decisive when implementing specific measures of incentives for the production of renewable Innovation Forever Publishing Group

“…However, this cannot be complete without the necessary information on the country's solar energy resources and their ability to support viable commercial large-scale solar power plants (SPP). A lot of literatures on Ghana's renewable energy potentials such as [12][13][14][15][16], have mainly been on policy and the identification of barriers that hinders the development of Ghana's RE sector. And one of the main challenges identified by some of these literatures is the lack of reliable information on the country's RE sector as well as their economic potentials.…”

The techno-economic potential of two different photovoltaic power plants (PPP) (i.e. PV-only and PV-Battery) systems under three different climatic conditions in Ghana were presented in this paper. The System Advisor Model was used to model a 20 MW PPP at Wa, Sunyani and Nsawam to assess their technical and economic performances. The research took into consideration monthly energy generation, capacity factor (CF), sensitivity analysis, tracking systems and some financial parameters. Results from the analysis shows that the PV-only and PV-Battery systems with fixed-axis tracking (FT) technology generated an annual energy of 31 GWh at Wa and 28 GWh at Sunyani and Nsawam in the first year. CF ranging from 16% to 18% were obtained for both systems with FT technology for all sites. However, the integration of tracking systems (i.e. single-axis (SA) and double-axis (DA)) increased the annual energy to between 36 and 43 GWh with corresponding increases in CF ranging between 21% and 25%. The LCOE also decreased from 8 to 10 ¢/kWh for the FT system to 5-6 ¢/kWh for both SA and DA systems. In general, the northern section (Wa) was identified as the best location for the development of large-scale PPP in Ghana.
