How do the energy values of PV architectures converge?

First, the energy values of the three architectures converge as an increasing fraction of energy from the coupled PV is used to charge the battery. Second, their capacity values converge to that of the battery as the capacity credit of stand-alone PV approaches zero.

How much does a PV system cost?

Our operations and maintenance (O&M) analysis breaks costs into various categories and provides total annualized O&M costs. The MSP results for PV systems (in units of 2022 real USD/kWdc/yr) are $28.78 (residential), $39.83 (community solar), and $16.12 (utility-scale).

Can energy storage improve solar and wind power?

With the falling costs of solar PV and wind power technologies, the focus is increasingly moving to the next stage of the energy transition and an energy systems approach, where energy storage can help integrate higher shares of solar and wind power.

Is energy storage undervalued?

Consequently, the energy storage component is likely undervalued. Capacity credit is the portion of nameplate capacity that can be relied on to contribute to firm capacity (i.e., the capacity that counts toward the planning reserve margin). All O&M costs for both PV and battery systems are fixed, so variable O&M costs are zero.

What drives PV-plus-battery capacity value at high PV penetration?

PV-plus-battery capacity value at high PV penetration is driven by battery capacity. Economic benefits of coupling depend primarily on cost savings. In this study, we explored how the value of hybrid systems comprising solar photovoltaics (PV) and lithium-ion battery storage could evolve over time.

What are the benchmarks for PV-plus-storage systems in 2022?

The MSP benchmarks for PV-plus-storage systems (in 2022 real USD/kWdc/yr) are $61.28 (residential), $75.25 (community solar), and $50.73 (utility-scale). For MMP, the benchmarks are $65.04 (residential), $76.79 (community solar), and $51.88 (utility-scale).
