Factoring in these costs from the beginning ensures there are no unexpected expenses when the battery reaches the end of its useful life. To better understand BESS costs, it’s useful to look at the cost per kilowatt-hour (kWh) stored. As of recent data, the average cost of a BESS is approximately $400-$600 per kWh. Here’s a simple breakdown:
2023 costs for residential BESS are based on NREL’s bottom-up BESS cost model using the data and methodology of (Ramasamy et al., 2023), who estimated costs for only alternating current (AC) coupled systems. We use the same model and methodology, but we do not restrict the power or energy capacity of the BESS to two options.
The power and energy costs can be used to determine the costs for any duration of utility-scale BESS. Definition: The bottom-up cost model documented by (Ramasamy et al., 2022) contains detailed cost components for battery-only systems costs (as well as batteries combined with photovoltaics [PV]).
Projected Utility-Scale BESS Costs: Future cost projections for utility-scale BESS are based on a synthesis of cost projections for 4-hour duration systems as described by (Cole and Karmakar, 2023). The share of energy and power costs for batteries is assumed to be the same as that described in the Storage Futures Study (Augustine and Blair, 2021).
The $/kWh costs we report can be converted to $/kW costs simply by multiplying by the duration (e.g., a $300/kWh, 4-hour battery would have a power capacity cost of $1200/kW). To develop cost projections, storage costs were normalized to their 2022 value such that each projection started with a value of 1 in 2022.
Modern BESS solutions often include sophisticated software that helps manage energy storage, optimize usage, and extend battery life. This software can be an added expense, either as a one-time purchase or a subscription model. Effective software can lead to cost savings over time by ensuring the system operates at maximum efficiency.

Energy in Paraguay is primarily sourced from hydropower, with pivotal projects like the Itaipu Dam, one of the world's largest hydroelectric facilities. This reliance underscores the need for a robust infrastructure, including efficient transmission networks and distribution systems, to leverage the country's renewable resources fully.
With a focus on clean energy production and partnerships with key stakeholders, Atome Energy is setting the stage for a significant transformation in Paraguay’s energy landscape. Atome Energy’s Paraguay project is centered around the production of green hydrogen and ammonia, two vital components in the quest for clean energy solutions.
[español] • [português] This page is part of Global Energy Monitor 's Latin America Energy Portal. In 2020, hydro power provided 100% of Paraguay's electricity and roughly half of the country's overall energy supply, with biofuels and imported oil accounting for the remainder.
Atome Energy is making waves with its ambitious plans in Paraguay. The green hydrogen and ammonia developer is rapidly progressing on its project in Villeta, and the outlook appears promising.
Permitting and regulation of energy projects is handled by the Viceministry of Mines and Energy. ANDE (Administración Nacional de Electricidad) is the state-owned entity responsible for satisfying Paraguay's electrical needs through generation, transmission, and distribution. Paraguay does not have a national oil company.
Paraguay has assumed various environmental commitments based on international agreements; among them the Paris Agreement and the fight against climate change; commitments reflected in guidelines established in the Energy Policy of the Republic of Paraguay 2040.
