8/3/24 – Yesterday was a start. Kingwood residents and political leaders met in several areas hard hit by Hurricane Beryl to discuss ways to improve recovery efforts. The idea: to start a dialog about steps that Houston Public Works, CenterPoint, community leaders, and residents can take together to reduce disruptions from future flooding and power outages.

Connectedness of Issues and Domino Effects

The recovery discussions took place on streets still clogged with debris that were near power line corridors, greenbelt trails, a school and two sewage “lift stations.”

Lift stations pump sewage uphill to treatment plants. When treatment plants are downhill, gravity does the work – a much more reliable solution. Without power, or when flooded, sewage from the lift stations can back up into people’s homes and overflow.

The City of Houston has hundreds of such lift stations. And during Beryl, Houston Public works shuttled backup generators back and forth between them. They tried to buy enough time to keep the lift stations from backing up and overflowing.

Unfortunately, the shuttling didn’t work in parts of Woodstream Village. There, residents talked about backed up sewage flowing from homes into streets and then Lake Houston.

The solution, according to a Public Works spokesperson Greg Eyerly, is to buy more generators. But that could take years in a city struggling with other urgent budget issues. And recovery can’t wait.

Preventing/Reducing Outages

Related recovery discussions about preventing or reducing power outages took place throughout the morning. According to the Federal Energy Regulatory Commission’s final 2004 report on Utility Vegetation Management, “tree touches” are generally cited as the single largest cause of electric power outages. They occur when trees, or portions of trees, grow or fall into overhead power lines.

In Kingwood, trees have grown up under or around power lines in many places. In fact, many residents have commented that if not for recent Beryl-related trimming, they would’t even have known power lines were there.

Unfortunately, from a recovery/electric reliability point of view, Kingwood is in a region that experiences frequent high winds and heavy rainfall. The heavy rainfall supports fast growth of tall trees. And frequent high winds push those trees into power lines.

So another major focus of recovery discussions included:

• CenterPoint vegetation management practices, especially maintenance intervals (which they avoided disclosing)
• Trees that fall from trail association property onto CenterPoint power lines
• Removal of debris that can clog storm sewers
• Who is responsible for what
• How one group’s performance or lack thereof can affect electric reliability and related issues for others.

Need for a New Approach Involving Trail and Community Associations

At-Large City Council Member Twila Carter said, “CenterPoint must have a collective conversation, resulting in a plan with KSA, the HOAs and Trail Associations to address maintenance. The thoughts of “In the past, that’s the way we’ve always done it,” or “the way it’s always been” no longer work for this community. We need to address the community as it is today, not how it was planned 50 years ago.”

District E City Council Member Fred Flickinger said, “A meeting between the trail associations and CenterPoint will make a significant difference. It was the best thing to come out of today.”

Flickinger was referring to a discussion with Dee Price, KSA President. Price agreed to set up a meeting with Kingwood trail associations, community associations, CenterPoint and the council members.

Flickinger continued, “There has to be significantly more aggressive vegetation management in the future.”

Kaaren Cambio, Dan Crenshaw’s assistant, explained how the homeowner and trail associations around Lake Conroe regularly inspect resident properties for trees and branches that threaten power lines. She said they send letters to residents requiring them to take down such trees or trim them back.

CenterPoint can trim back limbs and trees that encroach on their easements. But CenterPoint cannot take down trees on private property. That includes trail association property. So recovery needs to be a cooperative effort.

Chris Bloch, a long-time Bear Branch Trail Association (BBTA) Board Member, was not at the meeting, but observed, “The number of trees and limbs that fell during Beryl was easily 2X+ what we had during Ike. I attribute this to two summers of drought which stressed the trees and then an exceptionally wet spring.”

Costs of Burying Power Lines Not Clear

Flickinger also said, “I’m pushing for more underground electrical lines. I want to see the analysis of the costs. I know it’s expensive, but I believe we are paying for it incrementally every time there is a storm.” Flickinger cited lost wages, the cost of backup generators, debris cleanup, and more.

CenterPoint responded that the costs of burying wires are location specific and the costs of repairing underground cables, when cut, are much higher. However, CenterPoint offered no specifics about the cost of burying power lines in Kingwood.

Impacts on the Elderly and Ill

Cambio also talked extensively about the impact of power outages on hospitals plus nursing and retirement homes.

Many operate in multi-story buildings. Elderly in wheel chairs rely on elevators. But without power, they are trapped. They can’t get up or down stairs to get to doctors. Nor do they have power for dialysis, breathing machines, etc.

Kingwood Hospital had a backup generator. But, reportedly, it was insufficient to power the entire facility.

Cambio recommended changes to state law, requiring hospitals, nursing homes and retirement homes to have sufficient backup-generator power to operate elevators and air conditioning.

The only problem: According to Chris Coulter of Texas Power Agents, such backup generators require regular maintenance. They also require oil and fuel, such as gasoline, which may be hard to find during widespread power outages. After Beryl, the lines I found at functioning gasoline stations stretched for more than a half mile.

Voluntary Best Management Practices May Not Be Enough

I asked Coulter, who was not at yesterday’s roving recovery meeting, for recommendations about how to improve electric reliability.

He immediately focused on vegetation management and tied the growth of vegetation over time with the increasing frequency of power outages.

The FERC report cited above says that utility vegetation management programs represent one of the largest recurring maintenance expenses for electric utility companies in North America.

Coulter jokingly characterized companies like CenterPoint as “tree trimming companies that happen to distribute power.”

“The odds are that every single electric customer in the US and Canada has, at one time or another, experienced a sustained electric outage as a direct result of a tree and power line conflict.”

FERC and NERC Guidlines

This FERC report is well written and easy to understand. It makes dozens of common-sense recommendations to improve electric reliability. I recommend it.

Coulter also referred me to NERC, the North American Electric Reliability Corporation. NERC describes itself as “… an international regulatory authority whose mission is to assure the effective and efficient reduction of risks to the reliability and security of the grid.”

Coulter said that NERC rules recognize different sizes of lines in regard to vegetation management requirements. Heavy fines apply if vegetation is ignored around lines that carry more than 100 kV.

However, lines that carry less power often get neglected – something that hampers recovery.

Coulter said that many of his Kingwood customers told him about seeing several such lines for the first time after Beryl. They didn’t even know the lines were there because they were so badly overgrown!

Said Coulter, “The NERC rules are very specific about frequency and minimum vegetation clearance distances for larger transmission (above 100 kV). Fines are steep so the utilities pay close attention and abide by the rules. However, Kingwood has a large spiderweb of distribution lines that are below that bright-line designation.”

Perhaps the fines need to apply to smaller power lines.

Next Step: Broaden the Discussion

Dee Price is reaching out to trail and community associations to set up a meeting about vegetation management. It will also involve our elected representatives, CenterPoint and Houston Public Works.

At a minimum, I came away from yesterday’s discussions with a feeling that we need to:

• Raise awareness of vegetation management issues within the community
• Handle those on private property that could affect electric lines by ourselves
• Report problems on or near CenterPoint easements that they may not be aware of.
