Expected ROI of solar plus storage project in Guernsey 2025

What is the energy strategy for Guernsey?

The Electricity Strategy for Guernsey covers the period up to 2050. The Committee for the Environment & Infrastructure considered several different ways in which Guernsey could meet its future demand including solar, wind, tidal, additional interconnectors, energy storage and alternative fuels.

What is solar-plus-storage?

For solar-plus-storage—the pairing of solar photovoltaic (PV) and energy storage technologies—NREL researchers study and quantify the unique economic and grid benefits reaped by distributed and utility-scale systems. Much of NREL's current energy storage research is informing solar-plus-storage analysis.

How does solar-plus-storage affect energy systems?

Solar-plus-storage shifts some of the solar system's output to evening and night hours and provides other grid benefits. NREL employs a variety of analysis approaches to understand the factors that influence solar-plus-storage deployment and how solar-plus-storage will affect energy systems.

Can tidal energy be used in Guernsey?

The use of tidal energy was included in the process and assessed in the pathways and forms a part of one proposed supply pathway, 'Lighthouse', where the States of Guernsey would invest in innovative and up-and-coming technologies that are not yet commercially viable.

Is energy storage a viable option for utility-scale solar energy systems?

Energy storage has become an increasingly common component of utility-scale solar energy systems in the United States. Much of NREL's analysis for this market segment focuses on the grid impacts of solar-plus-storage systems, though costs and benefits are also frequently considered.

Can NREL optimize energy storage operation for utility-scale solar-plus-storage systems?

NREL researchers developed an open-source model to optimize energy storage operation for utility-scale solar-plus-storage systems in both alternating-current-coupled (left) and direct-current-coupled (right) configurations.
