Are energy storage projects a good investment?

Investors and lenders are eager to enter into the energy storage market. In many ways, energy storage projects are no different than a typical project finance transaction. Project finance is an exercise in risk allocation. Financings will not close until all risks have been catalogued and covered.

Should storage projects be funded?

One large missing piece has been funding. Storage projects are risky investments: high costs, uncertain returns, and a limited track record. Only smart, large-scale, low-cost financing can lower those risks and clear the way for a clean future.

What is an energy storage project?

An energy storage project is a cluster of battery banks (or modules) that are connected to the electrical grid. These battery banks are roughly the same size as a shipping container. These are also called Battery Energy Storage Systems (BESS), or grid-scale/utility-scale energy storage or battery storage systems.

Are energy storage projects a project finance transaction?

In many ways, energy storage projects are no different than a typical project finance transaction. Project finance is an exercise in risk allocation. Financings will not close until all risks have been catalogued and covered. However, there are some unique features to energy storage with which investors and lenders will have to become familiar.

Are energy storage technologies the key to reducing energy costs?

Energy storage technologies are also the key to lowering energy costs and integrating more renewable power into our grids, fast. If we can get this right, we can hold on to ever-rising quantities of renewable energy we are already harnessing – from our skies, our seas, and the earth itself. The gap to fill is very wide indeed.

Why is energy storage important?

Storage is indispensable to the green energy revolution. The most abundant sources of renewable energy today are only intermittently available and need a steady, stored supply to smooth out these fluctuations. Energy storage technologies are also the key to lowering energy costs and integrating more renewable power into our grids, fast.

How long is a 5MWh liquid-cooling energy storage cabin?
