Electricity Restoration in Puerto Rico #6MonthsAfterMaria at the Regional Level

Since late January 2018, the U.S. Army Corps of Engineers has been publishing regular snapshots of the number of meters connected to the electric grid at the regional level. These regions represent the Puerto Rico Electric Power Authority’s (PREPA) regional divisions. The following table provides some key information on each region.

PREPA Region Number of Meters Percent of Meters Number of Municipalities Per Region
Arecibo 153,407 10% 12
Bayamón 226,041 15% 8
Caguas 214,396 15% 17
Carolina 133,861 9% 9
Mayagüez 229,290 16% 15
Ponce 207,784 14% 14
San Juan 308,227 21% 3
TOTAL 1,473,007 100% 78

As of March 20, 2018, the USACE reports that 93.4% of the island’s 1.47 million electric customers are connected to the grid and the system’s generation capacity has been increased to an instant maximum production of 2258 mega watts – the highest reported amount since before Hurricane Maria made landfall.

While progress has been made, the sad reality is that more than 104,000 customers are still without power.

As the stacked bar demonstrates, the Caguas Region, which includes some the municipalities hardest hit by Hurricane Maria, lags way behind the other regions. This trend has been consistent since the USACE starting to share data on customers with electricity at the regional level.

chart (14)

The pie chart below puts in perspective in which regions the 104,000 customers without electricity live. And while the Caguas Region is the fourth biggest region in terms of the percentage of total customers, it currently has over half of the island’s customers without electricity.

In a recent video posted in the USACE’s social media accounts, the commander of the Task Force Power Restoration, Colonel Jason Kirk, explained that the numbers in the Caguas Region will start to improve soon, as crews and resources are being directed to this region.

The USACE and PREPA expect to have restored electricity to 95% of the island’s customers by the end of March. But many of the people living in towns located in the island’s central mountain range will not be as lucky. They should get their power restored by the end of May… a few days before the start of the 2018 hurricane season.



Restoring Puerto Rico’s Electric Grid at the Municipal Level: Does the Mayor’s Party Affiliation Matter?

AJ Vicens, a reporter who covers Puerto Rico issues for Mother Jones, noted in a tweet:

Someone I met in San Juan tonight compared electric grid restoration in different parts of town to gerrymandering.

I found this tweet interesting so I replied to Mr. Vicens’s tweet, asking what he thought the person meant by that statement. And he promptly replied:

I think it was implying that power resources are distributed based on political and other factors, not necessarily on need or in an even way.

When I visited the island last week, to visit family and do some research on the U.S. Army Corps of Engineers’ (USACE) and the Puerto Rico Electric Power Authority’s (PREPA) efforts to restore electricity, I also heard similar opinions. In addition, many people talked about countless alleged cases of corruption in PREPA. Some of these were covered by the local press – a subject that will be explored in a future Congressional hearing.

For now, let’s ignore the bribery allegations. I am interested in the following question: has politics played a role in the efforts to restore electricity to the island’s municipalities? In other words, does political party affiliation or political favoritism determined the USACE’s and PREPA’s efforts? And why do Puerto Ricans feel that this is the case?

Before we answer these questions, it is important to first note that Puerto Rico is divided into 78 municipalities, each with an elected mayor and an elected legislative assembly.

In terms of population, the biggest municipality is San Juan with 347,052 people and the smallest is Culebra with 1,818 people. While the pro-statehood, Partido Nuevo Progresista (PNP) won all the territory-level  institutions (i.e. the governorship, the legislature and the resident commissioner seat) in the 2016 general election, the pro-Commonwealth Partido Popular Democrático (PPD) won 45 of the municipalities. Over 2 million people live in municipalities controlled by the PPD, while close to 1.4 million live in municipalities controlled by the PNP. 

As of this morning, 179 days since Hurricane Maria made landfall in Puerto Rico, 92% of the island’s 1,473,000 electricity customers have power, leaving around 120,000 customers without power. As the graph below shows, since 2 January 2018, around 545,000 customers have been reconnected to the electric grid.

chart (5)

Unfortunately, we don’t have these customer level data for the last months of 2017 as PREPA’s computer systems could not calculate how many meters were connected to the grid. But the graph shows that the process to repair the electric system has been very slow and has frustrated many Puerto Ricans.

Another problem with this graph is that it does not actually tell us how many people have electricity at the municipal level. Since mid-January 2018, the USACE has been sharing the number of connected meters by regions. The regions corresponds to PREPA’s division of the islands into the following clusters: Arecibo, Bayamon, Caguas, Carolina, Ponce, Mayaguez and San Juan.

Since mid November 2017, some PPD mayors have questioned whether PREPA and the USACE have spent more time and resources addressing the electricity needs of municipalities controlled by the PNP. While PREPA officials have denied these claims, in mid January 2018, more PPD mayors, frustrated by the slow pace of the recovery, raised the same concerns. While Governor Ricardo Rosselló asked the mayors not to politicize the recovery efforts, his chief of staff, William Villafañe, admitted that the mayors needed access to more information on PREPA’s efforts. Villafañe’s efforts however have not addressed these mayors’ concerns, as many of them noted in a meeting hosted by the governor on 28 February 2018.

Given the island’s politics and Puerto Ricans’ frustrations with the slow recovery process, it is not surprising that many believe that the efforts to repair the island’s electric grid has been shaped by political connections to La Fortaleza – the governor’s residence. But, is this the case?

On 19 January 2018, Puerto Rico’s largest newspaper, El Nuevo Día, as a reaction to PPD mayors’ growing criticisms, published the percentage of meters connected to the electric grid in each municipality. As noted in the table below, 60% of the island’s electric customers had power. The average of customers with electricity in municipalities controlled by either political party was the same.

I recently received a copy of a map prepared by the USACE and PREPA for the 28 February meeting mentioned above. At the time, 80.5% of the island’s electric customers had power. The figures suggest that the average number of customers with electricity in municipalities administered by mayors of the PPD and PNP is roughly the same. But given that more Puerto Ricans today reside in PPD-controlled municipalities, the total number of customers connected to the grid is larger in PPD-controlled municipalities than in PNP-controlled ones.

Although I do not have recent figures, these numbers suggest that political favoritism probably did not influence the USACE‘s and PREPA’s efforts to restore electricity to Puerto Rico’s customers. Looking at averages is a tricky undertaking as these numbers can hide important trends. In future posts, I will break these numbers at the regional level. This may provide new ways to look at the data, discover new trends, and reveal insights that may answer these important questions.

While more research is still need, it is also critical to take this opportunity and reflect as to why the mayors and so many Puerto Ricans believe that the USACE and PREPA’s efforts are driven by political favoritism and corruption. Lack of trust in the island’s political parties or political institutions is not a new development. The slow recovery process has only heightened these sentiments and these will further complicate efforts to reform Puerto Rico’s economy and political structures.

Similarly, this lack of trust is also an outcome of a poor public relations strategy on the part of the Puerto Rico’s government. To be fair to the USACE and PREPA, they have used their various social media accounts to inform the world about their efforts. Although their communications do help us understand why it has taken so long to repair the electrical system, they have not addressed Puerto Ricans’ frustrations or anxieties.

Moreover, Puerto Ricans’ negative view of PREPA’s record of poor service has shaken their confidence on the public utility’s capacity to restore power to the island. Similarly, Governor Rosselló’s repeated criticisms of the USACE’s efforts has forced many Puerto Ricans to question its personnel’s commitment and resolve.

It is too late to correct these problems. But lessons need to be learned as Puerto Ricans start to prepare for the 2018 hurricane season.

The U.S. Army Corps of Engineers and the Generation of Electricity in Puerto Rico Post-Maria

In the last few posts, I have been looking at the U.S. Army Corps of Engineers’ (USACE) efforts to restore Puerto Rico’s electric grid after Hurricanes Irma and Maria. As I noted earlier, the USACE is not leading these efforts. It is part of the Power Restoration Task Force to Coordinate the Restoration Efforts, which is headed by the Federal Emergency Management Agency (FEMA) and Puerto Rico’s government.

The USACE’s efforts have been guided by a four-part strategy, which includes: (1) the installation of emergency power generation; (2) restoring electricity generation to the pre-Maria average of 2500-3000 megawatts (MW); (3) repair of the grid’s transmission system; and (4) the rebuilding of the distribution system.

Since 18 October 2017, the USACE has regularly provided a snapshot of PREPA’s electricity generation capacity. Echoing the Puerto Rican government’s information portal, StatusPR, electricity generation is expressed as a percentage. StatusPR’s measurement is problematic because it does not specify how much electricity the island’s power plants are producing at a given point in time. The USACE’s statistics are more useful as they provide the actual megawatts of electricity being produced on a daily basis. For example, on 16 February 2018, electricity generation stood at 1928 MW, while it was 2008 MW four days later.

The USACE’s numbers show that we can measure power generation via three different mechanisms. First, we can calculate the actual generation of megawatts per day, which the following graph captures.

chart (3)

Because the USACE’s goal is to restore the grid’s generation capacity to between 2500 and 3000 megawatts, we can calculate the daily amount of power generation against these two goals. In the next graph, the blue line represents the actual percentage of generated power reported by the USACE’s infographics and StatusPR. This is the actual number consistently reported by the media in their reporting. Thus, on 20 February 2018 the reported percentage is 85%.

The red line uses 2500 MW as the goal, while the yellow line sets the goal to 3000 MW. In this manner, each line represents the percentage of generated electricity based on these goals. On 20 February total generation equaled 2008 MW. Thus, this represents 80% of the total power the USACE wants to generate in the near future, if we use 2500 MW as the generation goal. Similarly, if we use 3000 MW as the standard, the island’s power plants are generating 67% of the goal.

chart (2)

What role has the USACE played in restoring the grid’s power generation capacities? An assessment conducted by PREPA and the New York  Power Authority found that most of Puerto Rico’s seven power plants experienced some damage because of Hurricane Maria. On 20 October 2017, the USACE’s Commanding General and Chief of Engineers, Lt. General Todd Semonite, explained that while damages to the grid’s transmission and distributions systems were the most challenging aspects of the restoration strategy, there was not “enough capacity in Puerto Rico’s existing power plants to provide electricity to the island.” Thus, one of the USACE’s main objectives was not only to work with PREPA to repair the existing power plants, but to also purchase and install new electricity generators.

On 16 October 2017, the USACE contracted the Pennsylvania-based Weston Solutions to install two 25MW generators in PREPA’s Palo Seco power plant. By the end of October, both plants were generating around 30MW of electricity, helping to “stabilize the power grid in the San Juan area”.  In an effort to provide electricity to manufacturing facilities, hospitals and other critical infrastructure in the southeastern towns of the island, the USACE awarded a contract in early November 2017 to Aptim Federal Services to install a 25MW generator in the Yabucoa power plant. The new generator became operational on 9 December 2017.

The USACE and PREPA, along with their contractors, have increased the grids capacity to generate electricity. While things have improved, it has been a slow process. And given the Stafford Act’s provisions, the most problematic aspect of this strategy is that these restoration efforts are not transforming the island’s electricity system. Hence the post-Maria electricity system will be highly dependent on fossil fuels and it will fail to meet current environmental standards.

The next posts will examine the USACE efforts to restore the electric grid’s transmission and distribution systems.

U.S. Army Corps of Engineers’ Power Restoration Strategy for Puerto Rico Post-Maria

In my previous post, I noted that Puerto Rico’s Governor, Ricardo Rosselló, has criticized the U.S. Army Corps of Engineers’ (USACE) efforts to restore electricity to Puerto Rico. His main criticism is that the USACE has not moved quickly enough to repair the island’s electrical system. In this post, I want to discuss the USACE’s role in the restoration efforts and its overall strategy.

The Robert T Stafford Disaster Relief and Emergency Act’s provisions inform the federal government’s responses to natural disasters. The act gives the Federal Emergency Management Agency (FEMA) the authority to coordinate the federal government’s relief efforts. FEMA relies on the USACE for emergency support for “public works and engineering-related” projects, which include everything from removing debris to the installment of “blue roofs”. FEMA can also provide the USACE long-term assignments in these areas, as it did on 30 September 2017 when FEMA tasked the USACE to assist PREPA’s efforts to rebuild the electric system.

Like FEMA, the USACE’s role in disaster relief is to support the state government’s restoration efforts. Thus, it is wrong to say that the USACE is in control over PREPA’s work. The USACE is part of the Power Restoration Task Force to Coordinate the Restoration Efforts. The following organizational chart, based on a recent PREPA document, captures the USACE’s role in the Task Force.

Organizational_Chart_PowerRest_TaskForce_PR2018 (1)

The USACE’s power restoration strategy can be divided into four elements. First, the USACE has been installing temporary emergency generators throughout the island. These generators, which most have been installed by the USACE’s 249th Engineering Battalion, have powered critical facilities, including hospitals, fire stations, water treatment plants, water pumps, and telecommunication towers and so forth.

The second set of efforts have been linked to the electricity system’s power generation capacities. The USACE’s goal has been to work closely with PREPA and private contractors to increase electricity generation to a level between 2,500 and 3,000 megawatts, which represents the electric system’s average peak load before the hurricanes struck the island.

The third element is the restoration of the electric transmission system. Hurricanes Irma and Maria destroyed 680 out of the 800 the transmissions towers that connect the system’s power plants to the distribution system. A recent study explains that only 15% of theses towers were built to withstand a Category 4 hurricane. It also noted the storm affected over two-thirds of the system’s 334 transmission and sub-transmission stations, which convert electricity to a lower voltage so it can be distributed to the system’s residential, governmental, commercial and industrial customers.

The fourth element is the rebuilding of the distribution system, which is “made up of roughly 1,200 circuits, with over 30,000 miles of overhead and underground lines.” Because that the system was not built to withstand a Category 4 storm, Hurricanes Irma and Maria knocked down over 50,000 utility poles and damaged close to 75% of the circuits.

This four-part strategy puts in perspective why restoring Puerto Rico’s electric system has been so challenging. And while the organizational chart shows that the USACE is not leading these efforts, for better and worse, it is the most important actor in the Task Force. In the next posts, we will look at the USACE’s work in the four elements of this strategy. This will give us an opportunity to further analyze its commitments to the overall effort.

Consequences of an Unrealistic Timeline: The Politics of Restoring Electricity to Puerto Rico’s Customers

BACKGROUND NOTE: In a previous post, titled “The Risk of Unrealistic Expectations”, I examine why restoring electricity to the island has been so slow. Since then, I have been researching this issue and it is now part of a wider academic project examining U.S.-Puerto Rico relations after Hurricane Maria. In this post, I focus on Governor Rosselló’s criticisms of the U.S. Army Corps Engineers’ (USACE) strategy and efforts to restore electricity to Puerto Rico’s customers following Hurricane Maria. The next posts look at the USACE’s strategy and examines the data connected to these efforts.

On 27 September 2017, the Federal Emergency Management Agency (FEMA) ordered the U.S. Army Corps of the Engineers (USACE) to work with the Puerto Rico Electric Power Authority (PREPA) to restore the island’s electric system, which was devastated by Hurricanes Maria and Irma.

From all the issues Puerto Rico has faced since Hurricane Maria, restoring electricity to the island’s customers has probably received the most media attention. It probably ranks as the most controversial topic of discussion among Puerto Ricans. The USACE’s efforts have not been  free from controversy. The main sticking point has been the timeline to restore electric service.

On 14 October 2017, writing in FEMA’s Blog, Brigadier General Diana Holland, the USACE’s Commander for the South Atlantic division, noted:

We believe that 80% of the system is affected, but that is only an estimate. We know that it took five months to restore the majority of power following Hurricane Georges… and I have been told that the damage this time is more extensive.

On that same day, Ricardo Rosselló, the island’s governor, announced PREPA’s timeline to restore electric service, promising that his administration would reestablish power to 95% of customers by 15 December 2017. Table 1 captures the governor’s timeline.

A week later Lieutenant General Todd Semonite, the Commanding General of the USACE, said that most Puerto Ricans should have power by the end of May 2018. The USACE’s timeline has not really changed since mid-October 2017. USACE officials believe that most customers will have power restored by the end of February 2018 and they hope to complete the entire project by May 2018.

Given the USACE’s views, why did Governor Rosselló announce such an unrealistic timeline? In an interview on 27 December 2017 with Agencia EFE, Rosselló insisted that USACE officials had personally assured him that they could meet his timeline. Of course, it is plausible that the governor was under this impression. But, it is unlikely that USACE agreed to this plan as PREPA’s executive director, Ricardo Ramos, told the press on 27 September 2017 that it would take six months to reestablish power to Puerto Rico’s customers. Moreover, repeated statements from the USACE personnel contradict Rosselló’s opinions on the matter.

In one of her recent columns, Sandra Rodriguez de Cotto argues that Ramos’s remarks did not sit well with the governor’s closest advisors. She also writes that the experience may have affected his connections to Rosselló’s inner circle and that his demeanor and body language had changed after the incident. Was Ramos pressured to conform with the governor’s timeline, even though he believed that it would take longer to reestablish power?

Two days before Rosselló’s announced his timeline, Ramos was asked by a reporter to explain when he thought power would be restore to the island’s customers, he said:

In terms of the power system restoration, for cultural reasons, we’re not saying exactly what the date is, because we will get expectations that will put pressure on the utility and its employees.

David Ferris of E&E News seems to have been surprised by Ramos’s remarks. He noted:

That statement would make the typical utility executive raise his or her eyebrows in disbelief. Confronted with angry customers, the CEOs of mainland U.S. power companies might prefer not to raise expectations about when a blackout will end. Yet they usually give their best guess, knowing that shrugging would only incur the wrath of customers and after them regulators and politicians.

Citing Puerto Rican lawmakers, Ferris concludes that Ramos’s statement is an outgrowth of PREPA’s corporate culture which places little value on transparency or public accountability. While his assessment is correct, his analysis fails to understand that Ramos’s statement was more calculated. Under pressure to conform with Rosselló’s more aggressive timeline, he decided to punt and let others answer the question.

It is this background that may explain why Ramos approved two controversial contracts with Whitefish Energy for $300 million and Cobra Energy for another $200 million. It could also explain why PREPA and the Rosselló administration did not sign mutual assistance agreements with the American Public Power Association (APPA) or other U.S. utilities in the mainland. Once these contracts were signed, PREPA officials believed these companies would help its crews meet the governor’s timeline.

But these decisions proved to be disastrous for the recovery efforts. FEMA and the USACE had not been informed of these two contracts and they did not approve them. Given Whitefish’s lack of experience, exorbitant charges and problems connected to the bidding process, the Rosselló administration was pressured by the U.S. Congress and FEMA to cancel the contract. While Rosselló distanced himself from the Whitefish scandal, emphasizing that he had little say in PREPA’s decisions, this strategy undermined Rosselló’s timeline and tainted his credibility with Puerto Ricans, lawmakers in Washington, and Trump administration officials.

After the cancellation of the Whitefish contract and frustrated by all the criticisms, Rosselló met with Nick Brown and Jessica Resnick-Ault of Reuters and during the interview he lashed out at the USACE blaming the slow progress to a “lack of urgency” among USACE officials. He noted that: “Everything that has been done right now has been done by PREPA or the subcontractors PREPA has had.” In addition, Rosselló told Brown and Resnick-Ault that because of the USACE’s slow efforts, his administration was pushed to sign mutual assistance agreements with utilities in New York and Florida to speed-up the recovery process.

Rosselló’s current views of the USACE’s efforts are still the same, but he has recently argued that the slow pace of the recovery efforts is tied to the island’s territorial status, suggesting the federal government has treated Puerto Rico’s disaster differently than other states’ natural disasters. Are Rosselló’s opinions correct? Has the USACE, when it comes to the the restoration of electric services, dropped the ball or treated Puerto Rico differently from other missions in the U.S. mainland?

I will explore in future posts. But for now, it seems clear that one reason why the restoration of electricity to Puerto Rico’s customers has been so slow can be linked to Rosselló’s decision to unveil an unrealistic timeline that pressured Ramos and his colleagues at PREPA to device an equally unrealistic strategy.
