Utility Scale Storage Battery Investments

The concept of storage batteries is not new to the electric power industry. However, the universal application of utility scale storage batteries as an integral component of the U.S. electric power industry transmission and distribution systems is quite new. Currently, the battery technology is on advancement trajectory with the expectation of higher energy density and lower cost. As a result, the U.S. regulators and public utility commissioners are mandating use of storage batteries and the electric utilities are gradually learning how to integrate storage batteries in their power grids. In parallel, the investment and finance communities do realize the potential growth of storage battery market. However, they have difficulty in making the economic case for such investments.

Arguably, the application of utility scale storage batteries is in its infancy. However, it has the potential to become an integral component of modern power grids thus creating huge investment opportunities for the utilities and private investors and even end-users.

The integration of a large number of intermittent and non-dispatchable renewable resources such as wind and solar power plants have created situations which are referred to as “Over- Generation”. That is, there is excess generation which cannot be used locally and due to lack of transmission capacity cannot be transferred to areas where load centers are located. In addition, rapid drop of generation during early afternoon as the solar plants reduce output has created a severe need for ramping capability. Further, the power production from wind and solar resources are not always coincident with demand. Therefore, the emerging power grids have a natural need for storing energy.

Storage technologies range from traditional pumped storage plants to the latest electro-chemical storage batteries and ultra-capacitors. The key storage battery attributes include high speed of response, controllability, modularity, scalability, expandability, flexibility and transportability. These are exactly the kind of attributes that the emerging power industry will need over the foreseeable future. In addition, recent advancements in material sciences include increases in energy density, reduction in size and space requirements and defect free battery manufacturing are expected to create viable economics for storage batteries. Further, advancements are being made in monitoring storage battery conditions, power electronics devices and controls, and smart bi-directional inverters. In an aggregate, advancement in storage battery technology and downward prices will create a very unique and natural position for storage batteries. Storage battery technology is therefore realistic, timely and achievable and can be made cost effective, thus becoming the obvious choice for storing energy for a stable electric and resilient power grid.

Similar to other new technologies there are challenges. The key challenge is creation of a compelling economic argument for battery storage.  The economic argument and value proposition are challenged by the following:

  1. Cost of battery cells
  2. Cost of interconnection
  3. Cost of network upgrade and balance of the system
  4. Life expectancy, number of charge cycles
  5. Operation and maintenance costs
  6. The revenue stream – Power purchase agreements or PPAs

This seminar provides an overview and guided tour of proven battery technologies from different manufacturers, challenges of interconnection, investment requirements, typical storage battery power purchase agreements, settlement equations and investment guidelines. The seminar materials provide valuable information on a full spectrum of applications for utilities, regulatory agencies, project developers, private investors, finance firms, wholesale market participants, and owners of existing wind and solar power plants.
