Project portfolio management (PPM) is a tool supported process by which organizations select projects and manage project portfolios using techniques similar to those employed by financial managers to optimize investment portfolios. Organizations, including utilities, are adopting PPM mainly because it enables them to make better project choices and, thereby, create more value while reducing risk.
However, PPM offers another advantage that at times can be extremely useful: when appropriately implemented, PPM can intelligently drive transformational change. In other words, if your business is currently at Point A and you wish to get to Point B, PPM can help ensure that you follow a reasoned and effective path to your destination. A timely example is provided by electric utilities that are developing PPM approaches that will help them create the smart grid.
Smart grid is, of course, the term used to describe the envisioned implementation of an ever-expanding set of computing and communication technologies for automating and improving the control of electricity distribution. Many see smart grid as the key to national efforts to improve reliability and efficiency, accommodate renewable energy sources, further energy independence, and reduce greenhouse gases.
Smart grid is an explicit goal of U.S. energy policy. Thirty states have adopted renewable energy standards, which require a pre-determined amount of a state’s energy mix (up to 20%) to come from renewable sources by as early as 2010. Cap and trade legislation, if passed, will increase the costs of traditional energy. The Department of Energy has announced the availability of $3.9 billion in grants for modernizing the electric grid. Clearly, there is plenty of top-down momentum for smart grid.

But smart grid will need to be constructed from the ground up. Utilities have been criticized for “dragging their feet” with regard to smart grid, but it makes sense for utilities to be cautious when it comes to investing limited resources into new and unproven technologies. Utilities must be able to demonstrate to investors and regulators that the projects they undertake produce benefits that justify costs.
A challenge for utilities considering smart grid projects is that the main benefits of smart grid investments are customer and societal benefits, benefits that aren’t reflected on utility balance sheets. Given economic realities and lack of assurance that utilities will be able to recover investment costs, it may be tough for utilities to make a business case for many socially desirable smart grid investments.
Suppose, for example, that a proposed smart grid project would reduce the frequency or duration of outages. Conducting that project would enable the utility to avoid the revenue loss associated with failing to deliver the expected power, but this benefit to the utility is much less than the larger benefit to customers who, for example, might lose perishables in their refrigerators if an outage is prolonged. Similarly, a smart grid project that would lessen electrical demand would reduce the amount of pollutants discharged from petroleum-fueled generation plants. This, in turn, could produce environmental and health benefits for society at large, but the main impact to the utility would be reduced revenue.
Recognizing the bias inherent in traditional utility-centric, project evaluation methods, a growing number of utilities, including Washington State’s Puget Sound Energy (PSE) and Pennsylvania’s PPL, are adopting PPM approaches that explicitly quantify customer and societal benefits. For example, Martha Dodge, PPL’s Senior Director for Planning and Engineering, states, “Our prioritization model values projects from the customer’s perspective — How much benefit will the customer derive from the proposed project?” Customer benefits that are quantified include customer cost savings and the value to customers of improved electric service reliability.
The models or tools that these utilities are using value projects in two steps. First, templates are provided to facilitate the estimation of the impacts of proposed projects on customers and others. For example, if a project improves reliability, how many customers will be impacted and by how much will the frequency and/or duration of outages experienced be reduced? If a project reduces emissions from burning fossil fuels, how much less fuel will be required?
The second step is to translate customer and societal impacts into equivalent dollar values. Although the dollarization of benefits is difficult, utilities can leverage results from academic research, other industries, and the government. For example, numerous studies have quantified the value to customers of avoiding outages, government agencies have recommended values to place on health and safety, and the auto industry has developed assumptions for quantifying the social benefits of reducing pollution.
For completeness, the models also include other hard-to-quantify but potentially important benefits. For example, projects can impact the stakeholder perceptions of the utility and create goodwill in the marketplace. Such perceptions are important because they can affect funding in equity and credit markets and impact the utility’s ability to obtain necessary project approvals. Likewise the models typically account for risks and allow project value to be adjusted based on the utility’s risk tolerance. Smart grid risks that concern utilities include network security breech, infrastructure obsolescence and communication reliability.
Finally, since there are often interdependencies among proposed smart grid investments (obtaining full value requires implementing a suite of related projects), the models allow scenarios of phased investments to be investigated to support long-term strategy choices.
The models for valuing projects should be designed collaboratively by a team composed of individuals whose understanding encompasses all of the diverse needs that motivate projects and the wide range of impacts that project decisions have on the business. As Mark Velicer, PPL’s Senior Director of Finance and Regulation, notes, “It is important to engage stakeholders in the design of the model, to establish buy-in and ownership, and to ensure that all sources of project value are represented.”

Including customer and societal benefits, as well as risk, in project valuations allows utilities to prioritize smart grid projects together with more traditional, low-tech capital and maintenance projects. But utilities that are taking this course are realizing another advantage—they are finding that the process of designing their PPM approaches, particularly the step of agreeing on the logic for evaluating and prioritizing projects, promotes culture change that will help them to play the role of gatekeeper for many smart grid projects. Specifically, when executives back a project evaluation process that puts substantial weight on creating value for customers and society, they provide a clear message to their managers and staff about where effort should be focused.
Also, utilities are finding that the adoption of an explicit logic for valuing and prioritizing projects helps them respond to external demands to explain their choices, especially important if rate increases are needed to make smart grid investments viable. Including customer and societal benefits when valuing projects is attractive to regulators and consumer advocates.
Lastly, the approach provides a pragmatic means for encouraging the implementation of smart grid projects that make the most sense for specific utility situations. When a utility identifies a project that, although not economically attractive to the utility, would generate high customer or social value, the utility can alert regulators and government agencies and seek help in the form of pricing flexibility, cost recovery, or subsidies to make the socially desirable project financially viable for the utility. If regulators disagree with the logic used by the utility to value customer and societal benefits, they can suggest changes to the value models. Regardless, if PPM can assist regulators and utilities in obtaining agreement over the value and priority of proposed projects, it will certainly facilitate the development of the smart grid.
In conclusion, PPM provides a pragmatic, bottom up perspective to complement the top-down push for smart grid. It will help utilities and regulators maintain a clear vision of the desired destination and ensure that the path forward will realize value at every step along the way.
Project interdependencies pose a particular challenge in portfolio optimization. Such dependencies fall into two broad categories:
In this post, we only concern ourselves with hard dependencies. The wrench that foundation projects throw into a portfolio optimization effort is this: how do we prioritize projects that seem to provide little intrinsic benefit, yet are indispensable for “juicier” projects to be available? A simple examination of their benefit-to-cost ratio is clearly inadequate if by benefit we only mean their intrinsic benefit. But is there a possibility of simply redefining what benefit means for such foundation projects? Is it possible to somehow augment the benefit of these foundation projects with the benefit of the projects they enable? Unfortunately, the answer is no: things get more complicated in the presence of multiple dependencies. The following example gives us a window into why.
Consider the following mock portfolio. We simplify the presentation by reducing each project to two numbers: its benefit and its cost (we won’t go into the details of how we boiled down the benefit to a single value, here). An arrow represents a requirement: the project at the origin of the arrow is required for the project at the end of the arrow to be available.
The following table tells the story of what the optimal portfolio looks like for an increasingly higher budget. (The reader could easily verify this by hand.)
|
Total Cost |
Projects Funded |
Total Benefit |
Comment |

50 |
2 |
10 |
With that small a budget, only foundation project #2 can be funded, although it provides minimal benefit. In practice, one might elect not to fund it at allsince the portfolio B/C ratio is only .1. |
|
60 |
2+5 |
60 |
Small project #5, dependent upon foundation project #2, can now be funded. Notice that the combined B/C ratio is barely at breakeven now, i.e., equal to 1. |
|
110 |
1+2+5 |
65 |
A budget increment of 50 allows us to fund the second foundation project (#1), but the portfolio B/C ratio takes a hit again (.59). |
|
150 |
1+3 |
205 |
The availability of a budget of 150 makes project #3 with its intrinsic B/C ratio of 2 very appealing now. Here, we would sacrifice the 2+5 project combination (and its neutral combined B/C ratio of 1, as discussed above) to free the budget necessary to fund project #3. |
|
200 |
1+2+4 |
315 |
For an additional budget of 50, we can now fund both foundation projects and drop project #3 to instead fund the attractive project #4, which has the highest intrinsic B/C ratio of the set. |
|
210 |
1+2+4+5 |
365 |
Small project #5, again, nicely accommodates a small budget increment of 10, for an appealing incremental benefit. |
|
310 |
1+2+3+4+5 |
565 |
At this budget level, everything can be funded. |
This table showcases some of the subtleties associated with the valuation of a foundation project. If somebody were to ask, what is the “full benefit” of project #2 (not just its intrinsic benefit), the answer would be very different (if at all defensible) depending on the line we examine in this table.
At the heart of this difficulty lies the following fact: in the presence of dependencies no easy ranking method allows one to decide how or when to fund certain foundation projects. Instead, a full-blown optimization is required, taking into account the entire universe of projects. We have already discussed this topic in this previous post.

More than 80 providers supply software tools for project portfolio management (PPM). Chances are, only a handful of the offerings will be suitable candidates for your application. How can you tell which vendors and tools deserve your attention?
Most PPM software evaluation guides recommend that you ask questions that play to the vendors’ strengths: they encourage you to discriminate various features and capabilities that support good project management. But, PPM is about selecting the right projects, not just doing projects right. Here are some important, but often neglected, questions that can help you assess whether a vendor’s product will actually help you achieve the primary goal of PPM; namely, to identify and select the project portfolio that will deliver the greatest possible value to your organization.
