Renewables may break century-old utility rules


Renewable sources of power generation, such as solar, wind, and batteries, are displacing fossil-fueled power generation. The reason? the price They generate cheap electricity. It is also somewhat more complex because it is also a technology transfer away from fossil fuels, and its rate of absorption throughout the economy is rapid. But when competing businesses, which produce similar goods, such as electricity, begin to differ fundamentally in terms of their underlying cost structures, winners and losers emerge.

One of the surest casualties of renewable penetration may be the regulatory framework of our state and federal Public Utilities Commission. The specifics here are complicated, and we’ll address them later. But the root cause of essential organizational failure is simple. Organizers today are proverbial. All they can do is decide to raise customer rates (and how much), which is why we hear so much from critics about a potentially inevitable utility death spiral where commission-authorized rate increases lead to a cycle of customer (and revenue) losses that lead to further rate increases until a financial crisis occurs. We’re not big fans of this hypothesis though so we’ll see if the big C&I customers can be bid away from being leveraged by renewable providers. Currently there is too much growth in electricity demand to divert utility from being an immediate problem. But we still argue that organizational weakness is embedded in the nature of institutions and therefore cannot be cured.

Public utility commissions first appeared in the United States in 1907, just as extraordinary gains were made in the efficiency of central station electricity. The first fifty years of utility regulation involved overseeing the development of an almost unprecedented industry that began as a modest urban enterprise and ended with the concept of universal service. Regulators must balance a problem: how do we finance the growth of the employment system and avoid the exploitation of captive buyers? Our argument is about where we go from here. These institutions are not even remotely capable of doing the opposite. Nor because of concerns about agency “capture” by industry, which may or may not be valid. They can’t because of the interesting idiosyncrasies of the utility business.

There are two types of utility costs, fixed and variable costs. Fixed costs represent the hard assets of the business (production, transportation, and distribution), while the largest variable cost is fuel. Until the price chaos and inflation of the 1970s, the main focus of early pricing was mainly on the fixed cost side, plant and equipment. The whole building block of cost of service pricing, the essence of profitability pricing, basically asks the company two questions: 1) How much did you spend on plant and equipment to serve people? and 2) what is the appropriate capital structure (% debt vs. equity) and appropriate return on shareholders’ equity that should be used to determine the price. They can do this safely because utilities consistently reduce operating costs, which in turn benefit consumers.
