Technology upends the utility business model

Utilities view solar the way taxis view Uber

Second in a three-part series. The first part, on natural gas pipelines, can be found here.

IN THE SHARING ECONOMY, new consumer technologies and business models are upending industries from transportation to accommodation, opening up markets previously dominated by established players. Similar forces are sweeping over the energy sector. A homeowner who feeds surplus electricity into the grid competes with electricity generated by large power plants. Even without solar panels, a customer can provide value to the grid by dialing back on air conditioning on a hot summer day, reducing the need for additional power plant generation and all of the expensive utility infrastructure – poles, wires, substations, and related equipment – built to meet peak electrical demand.

New approaches to energy management and declining costs for solar and other consumer energy technologies have the capacity to revolutionize the energy sector, but the rules will have to change to accommodate innovation. As it stands now, utilities are compensated based on the amount of infrastructure they build and maintain. Utilities thus have no financial incentive to facilitate the adoption of technologies that reduce the need for infrastructure. In an additional wrinkle, energy services provided by consumers are often more valuable than their traditional equivalents: solar power provided close to where it is consumed avoids not only the cost of energy from a power plant, but can also avoid costs for expensive grid infrastructure required to transport energy from a power plant to the consumer.

Part II of this series describes how new technologies and approaches to energy management are transforming the utility sector, with particular attention to solar energy and efforts to modernize how we manage and pay for the grid. This focus builds on Part I of the series, “The case against gas pipelines,” which describes the need to reduce climate pollution while minimizing expenditures on large-scale infrastructure such as natural gas pipelines that run counter to both climate goals and trends that are decentralizing the grid.


Distributed solar is the most visible force driving democratization and competition in the energy sector. Costs for solar have declined so significantly that generating one’s own power is already – or will soon be – competitive with buying power from the grid in many parts of the United States. Some developing countries are leapfrogging traditional grids and going straight to solar, mirroring the rapid adoption of cellular communications that avoided the need for expensive land lines.

Where grids already exist, solar provides value by offsetting costs that ratepayers and society as a whole would otherwise pay. Acadia Center calculated the value that a unit of distributed solar power provides to the grid and to society – including energy, capacity (the value of having generation sources available when needed), price reduction impacts, and avoided emissions.

Acadia grid societal value

When accounting for these diverse values, a unit of energy from rooftop solar is worth more than a unit of energy from a conventional, fossil fuel-powered generator. Some take issue with counting benefits beyond energy alone, but in a modern energy system where needs can be met with a wide array of resources, the unique attributes of each resource must be considered.

Accounting for the value of energy produced in different locations requires a new way of managing and paying for the power grid. Gone is the simplifying assumption that additional energy infrastructure is the only way to meet energy needs. In its place, policymakers must structure energy markets and incentives to meet customers’ needs in the most cost-effective, non-discriminatory manner possible. A rooftop solar panel on its own will not replace the need for an entire power plant or utility substation, but even a small portion of the tens of thousands of roofs in Massachusetts could go a long way to meeting our energy needs, while at the same time generating income streams for new market participants and fostering competition.

Massachusetts is currently grappling with the disruptive challenge of solar: seeking to align incentives with declining solar costs while preserving a sustainable solar market. The heart of the debate focuses on a policy called net metering. Net metering is a way to compensate customers by spinning the electricity meter backwards for power fed into the grid and netting out consumption against generation each month. Each unit of electricity fed into the grid is credited at the full retail rate – the charge for energy produced by power plants, plus the distribution, transmission, and other costs to deliver power to a customer.

When considering modifications to net metering, a cautionary example is provided by Nevada, which recently took the draconian step of reducing net metering credits for solar power to the price of energy alone. As a result, solar development and jobs are evaporating and homeowners and presidential candidates are objecting to a policy that undercuts investments made in good faith. Similar concerns were raised by almost two-thirds of Massachusetts House members in a recent letter objecting to significant changes to net metering rates until an official, publicly scrutinized analysis of costs and benefits is conducted.

The way forward is to develop an approach that would reduce costs and promote solar development where it is most needed by adjusting net metering credits based on the value of different types of solar projects. In order to support diverse project types and create a stable solar market, compensation must be adjusted through modifications to net metering credits rather than through add-on incentives. Under such an approach, large, stand-alone projects that feed all of their power into the grid would receive credit for value to ratepayers including: 1) producing clean energy, 2) avoiding costs associated with high-voltage transmission lines needed to move power to or around Massachusetts, and 3) reducing energy prices across the region. Rooftop projects meeting on-site demand would be credited for the values above, and for avoiding costs that would otherwise result from overbuilding the distribution system to meet peak demand. Solar projects would also pay their fair share for system upgrades needed to accommodate power fed back into the grid.

Scaling compensation by different project types is at the heart of Acadia Center’s Next Generation Solar Framework. Under this approach, solar producers would be credited for avoiding costs that customers otherwise would have to pay for grid-supplied energy, while covering fair costs for solar integration.  This approach would address concerns about cost-shifts between customers with and without solar. It would also provide a strong economic framework for continuing “virtual net metering,” a policy that treats certain offsite solar developments as if they were on a customer’s roof. Virtual net metering is crucial for providing equitable access to shared projects for consumers who cannot install solar themselves, and for enabling projects that benefit low-income ratepayers. Any additional payments from incentive programs (such as the Solar Renewable Energy Certificate, or SREC, program) should be structured to be cost-effective and minimize ratepayer costs.

Utility Pushback

The current regulatory structure is ill-suited for an increasingly democratized energy system, where independent producers and customers are competing with incumbents rewarded for building energy infrastructure. Under the current system, utilities can receive 10 percent or more return on equity for transmission and distribution system investments, and little or nothing for integrating consumer resources such as solar. With these skewed incentives, it is not surprising that utilities across the country are pushing policies that would undermine competition from distributed resources.

When solar panels were sparse, the simple practice of net metering at the full retail rate appealed to utilities and regulators for administrative simplicity and general approximation of value: a unit of energy produced on-site avoids the cost of supplying that unit at the retail rate. However, with costs of solar plummeting and installations no longer sparse, utilities now see solar akin to how taxi companies see Uber: as competition for market share and a threat to the bottom line. Each rooftop solar system reduces utilities’ sales, meaning they have to spread costs over fewer units, and each unit becomes more expensive. As electricity becomes more expensive, customers have greater incentive to install solar or improve efficiency, creating a vicious cycle that erodes utilities’ customer base.

In response to the threat of solar, utilities across the country – and in Massachusetts – are proposing to significantly cut compensation below the retail rate. Utilities and large business groups have argued that with solar costs coming down, incentives should decline as well. Cutting the incentives (SRECs) layered on top of net-metering is appropriate as the Massachusetts solar market matures, and the costs of these incentives have been declining.  However, cutting the net metering credits for all solar projects to the bone would likely crater the Massachusetts solar market, as it has in Nevada. As solar development dries up, customers will revert to spending more on utility infrastructure – and utility profits will increase.

Increasing fixed customer charges (the portion of customers’ bills that remains unchanged from month to month) provides utilities with another means to fight off competition from solar. Higher fixed charges have two main impacts: 1) they reduce the per-unit cost of power, thereby cutting compensation for solar net-metering, and; 2) they reduce customer control over energy bills, undermining the incentive to reduce consumption. Higher fixed charges are also regressive, increasing bills for below-average energy users, as shown in Acadia Center’s UitlityVision.

Acadia fixed charges


This regressive impact has led to widespread opposition to increasing fixed charges. In Connecticut, opposition to increased fixed charges united AARP, Walmart, Gov. Dannel Malloy, and Sen. Richard Blumenthal, who called for a federal review of “unconscionable” proposals. The issue is now coming to Massachusetts, as National Grid has proposed to establish new, tiered fixed charges. The utility recently withdrew a similar proposal in Rhode Island, where it faced widespread opposition, but in Massachusetts National Grid has yet to pull back from its proposal.

Accommodating Disruption

Just like ride-sharing and room-renting, rooftop solar and other distributed energy resources are not going away. Solar panels will continue to get cheaper and more efficient, and home energy management systems will enable greater consumer control over usage and costs. The implications are wider than rooftop solar, requiring fundamental redesign of a historically centralized, one-way energy system. Consumers able to reduce overall consumption and peak demand will require less energy and a smaller energy system, contracting utilities’ rate base, reducing sales, and fundamentally shifting the utility business model.

In response to these challenges, the Massachusetts Department of Public Utilities (DPU) three years ago initiated an effort requiring utilities to use new technologies to avoid outages, reduce peak demand, integrate distributed resources, and improve utilization of existing capacity.

While admirable in its objectives, this “grid modernization” proceeding has not to date addressed the fundamental challenges and opportunities facing Massachusetts’ utilities. Plans filed last August (and now under review by the DPU) differ widely in scope and ambition. All National Grid customers could receive advanced energy meters, enabling better management of customer and system-wide energy demand, while Eversource would provide advanced meters to only the estimated 5 percent who file the necessary paperwork.

In a worrying departure from the DPU’s order for plans focusing on “optimizing demand, which includes reducing system and customer costs,” utilities do not even attempt to account for savings on transmission and distribution expenditures enabled by new technology. (See Acadia Center’s summary of the grid modernization plans). Without realigned financial incentives, Massachusetts will not succeed in compelling utilities to adapt business models, embrace new technologies, and truly modernize the grid. So long as installing transformers is more lucrative than helping customers manage energy usage, the grid will remain over-built, outdated, and inefficient.

There are other models. As part of ambitious reforms underway in New York, utility incentives will be tied to modernizing the grid and managing resource-agnostic energy markets that would appropriately value centralized power plants, rooftop solar panels, consumer demand savings, and even power from electric vehicles.  (Acadia Center’s comparison of the New York and Massachusetts processes is available here).  New York’s success is not guaranteed, but the state’s willingness to tackle new realities head-on has improved ratings for its utilities, which are considered lower risk for being ahead of the market and regulatory curve.

Adapting to disruptive technologies requires policymakers to find a balance that reaps the benefits of innovation while protecting consumers. Proposals to require background checks and insurance for Uber drivers rather than shutting the service down attempt to find that balance. In the case of solar, scaling back on incentives (SRECs), while better valuing the unique benefits of distributed, clean energy and maintaining equitable access would chart a similar path.  More broadly, re-aligning utility incentives to facilitate adoption of emerging technologies and truly modernize the grid would deliver economic and environmental benefits, while empowering the consumer.

    There is tremendous confusion between power and energy. Power (watts) is the service provided by utilities to be sure that the light always turns on when we flip a switch. Energy (watt-hour) is what the lightbulb consumes when it is on. Utility cost is related to how much power the grid needs to function effectively. Utility cost is fairly apportioned to consumers by how much energy each consumes in a given period for convenience.
    When the state mandates that a consumer can place solar panels on his roof, connect to the grid, substitute whatever energy the sun generates in place of what utilities normally expect to supply, and then force utilities to buy any extra energy whether it is needed or not, the whole system is disrupted unfairly. No mater how many panels are installed, utilities still need to supply the same amount of power (megawatts) just in case it is cloudy. The savings accrued to those lucky enough to have south facing roofs and can afford to buy solar panels comes as a result of shifting those costs to the rest of us.
    The rest of us are screaming at the higher rates. State regulators are putting the squeeze on utilities. Utilities are just pointing out that if people want solar energy they need to pay their fair share. The only way that individuals and others can be viewed as utility competitors is if they invest in enough energy storage, and disconnect from the grid. Until then, they are being granted a free ride on the grid. They are not paying for the service they receive.
    Any claim that solar energy benefits the grid is false. Any claim that solar energy reduces carbon emissions is unproven.
    In the absence of grid scale energy storage, intermittent and variable power (wind and solar) is a drag on the economy, a net job loser, and fails to avoid carbon to any significant degree.

      Repeat of comment from elsewhere, but since you repeated it, I can, too:

      That’s completely untrue. No electric grid which has or had one or more nuclear power plants will have any trouble at all with the fluctuations which wind and solar produce, ESPECIALLY if the wind and solar are distributed over large spaces. That’s because nuclear power plants, like Pilgrim’s 685 MW, can go offline at a moment’s notice, for safety reasons, taking their 685 MW with them. The biggest offshore wind turbines are about 4 MW apiece and, while they may fluctuate, they don’t do so in unison. Onshore wind turbines are anti-correlated with solar energy. Off-shore less so, but it is true that in the conditions where there is ample wind solar tends not to be available, and a plurality of the time the reverse is true.

      The key facts about large scale wind and solar are that they are reliable as a source of energy and at a fixed price. Fossil fuels fluctuate in price all over the place, always have, and always will.

      • NortheasternEE

        The issue is not that Pilgrim cannot be turned on and off. The issue is that state mandates for renewable energy are forcing Pilgrim to operate in a manner that is dangerous and uneconomical as this MIT report states:
        “Researchers found that, even now, increasing amounts of intermittent renewables are forcing grid operators to order cycling of fossil fuel thermal plants in order to keep the grid balanced. While natural gas combustion turbines can start and stop fairly quickly, coal and nuclear plants were designed to run flat out, with start up and shut down taking comparably longer.

        For nuclear, load-following – raising and lowering power to compensate for renewables whose output varies over time, like wind and solar – stresses equipment and raises safety issues, said MIT Professor Howard Herzog. Moniz added that nuclear operating costs are so relatively low that decreasing nuclear output makes no economic sense.”
        Yes, on occasion the 685 MW from Pilgrim can go off line. But comparing this event to a 4MW wind doesn’t cut it. The plan is for the grid to have 12,000 MW of wind power. That is a third of total grid capacity. When a weather front goes by, all 12,000 MW can go off line. In the middle of Summer during peak demand, a Bermuda High weather system can hang around for days even weeks causing heat waves without a breath of air from most of the coast north of Cape Hatteras, NC.
        Without large scale energy storage, wind and solar power are worthless in every respect. That is the lesson we need to learn from the Europeans who are failing to meet their renewable energy goals.

    The only financial obstacles keeping home PV owners from “hoarding their electrons” are (a) the current high price of energy storage, and (b) SRECs in any form. If batteries are put between a home and the grid, the home is no longer eligible to receive SRECs. But, then, if SRECs are taken away, that no longer matters. Energy storage costs are decreasing, and the financial costs may soon plummet, with New York States big surge into the business, and the emergence of commercial scale energy storage, where a company will buy excess power from a private residence with solar PV, and sell it back to them, making its money in-between as a “virtual energy generator”. Note that a substantial number of the fossil fuel and methane or oil generators in New England only operate less than 10% of the total time when loads spike.

    The accounting structure which blames solar residential PV for spiking energy prices is simply wrong, based upon arithmetic and physics. First of all, even if ALL the transmission costs for all solar PV residences were assigned to everyone else, there are so few solar residences at present that it could not move the needle on overall cost. The claim that it does is a red herring. Second, to the argument that solar residences should receive wholesale rates for generation to the grid because they are using a construct which costs so much per year to maintain is a fiction, since most of the electrons the solar residence pushes are in fact consumed by their non-solar neighbors. And, yes, the grid does not need to supply those neighbors with the portion of electricity the solar neighbors contribute. But the point is that because the electrons remain local, not much of the transmission grid is traversed, so the claim that it is “used” is either disingenuous or a side effect of how the contracts and accounting for it is done, fungibility of electrons and all that.

    And what’s this rubbish about a “state [mandating] that a consumer can place solar panels on his roof, connect to the grid, [and] substitute whatever energy the sun generates in place of what utilities normally expect to supply …”? The state and the community DO NOT OWN MY HOME. If I want to be completely independent from the grid, or buy as little or as much as I want, that’s MY business, and the state and the utility — which is really just a Stalinist cooperative — have no right to dictate to me what I do. Sure, they can negotiate the rates at which I buy or sell power to the grid. But, as in any free market, they — and all the people who continue to rely upon the grid — have every reason to expect that I will optimize my situation, and if it is more expensive to operate my situation, I’ll move away from whatever is costing me more. That’s just business.

    The trouble is that the utility and grid model are obsolete. It would be better and cheaper to recognize that sooner, and begin to break it up into a bunch of decentralized pretty much self-sufficient components who borrow among themselves and from a central hub when they need to, but that is rare.

    The sad facts are that Beacon Hill is captured by big business, including utilities and the Associated Industries of Massachusetts. The high rates for electricity in Massachusetts are an anomaly compared to the rest of the nation. They are that way because of both entrenched interests and poor planning and have been that way LONG before wind and solar were a presence in Massachusetts, e.g., Massachusetts is WAY too dependence upon natural gas (also known as explosive methane). It has long been. Its energy costs are high because fossil fuel prices are volatile and generation lags prices by investment and build time. Solar and wind generate at the same price, and consistently when averaged over a year. Land based wind turbines are cheaper than any other energy source except energy efficiency measures using UNSUBSIDIZED COSTS FOR COMPARISON. (See Residential solar is expensive on the same (unsubsidized) basis, but that comparison is unfair since only a fraction of the captial that is used for installing and integrating this energy source comes from the general public. Moreover, as another installment on this subject here has argued (see, residential solar has social benefits well beyond energy. For instance, it is completely flexible. If cost and electricity rates were the ONLY consideration, we should go crazy building land wind turbines. But, we are willing to embrace a Price Of Anarchy and tolerate NIMBYists, forcing wind to be FIVE TIMES MORE EXPENSIVE (unsubsidized cost; see Lazard).

    So I would say to anyone who complains about electric rates that until they are FIVE TIMES HIGHER than they should be, they have no complaints, because they could have energy five times cheaper if they insisted that land based wind turbines be built where they generate, and not consider the opinions of nearby neighbors. Consider them if you like, but energy prices are higher as a result.
