ElectricServiceAreaLocal

Holland Board of Public Works (HBPW) is a local public power provider. Living in the community that we serve makes you more than a customer of our utility – you are also an owner. We serve electricity to the City of Holland and surrounding townships (Holland Township, Park Township, Laketown Township and Fillmore Township).

Serving the community is HBPW’s top priority. Beyond providing reliable and affordable electric service, HBPW invests in strengthening and connecting the greater Holland area. Every dollar that we receive is invested back into the community.

As a public power provider, HBPW maintains local control, low rates and high reliability. Local governance gives community citizens a direct voice in our decisions and policy-making. HBPW facilitates economic development. The quality and affordability of our service attracts jobs that enrich the lives of people living in the greater Holland community.

Reliable

HBPW is proud to be a Reliable Public Power Provider (RP3)®. RP3 is a designation from the American Public Power Association for providing reliable and safe electric service. The RP3 designation recognizes public power utilities that demonstrate proficiency in four key disciplines: reliability, safety, workforce development and system improvement. Criteria include sound business practices and a utility-wide commitment to safe and reliable delivery of electricity.

How we measure reliability - SAIDI and SAIFI

SAIDI and SAIFI are two of the indices use to measure distribution system reliability. These indices account for frequency, duration and number of customers affected in outages.

The System Average Interruption Duration Index (SAIDI) is the average outage duration for each customer served, and is calculated as:

      • SAIDI = sum of all customer interruptions / total number of customers served
      • SAIDI is measured in units of time, often minutes or hours. It is usually measured over the course of a year.

The System Average Interruption Frequency Index (SAIFI) is the average number of interruptions that a customer experiences, and is calculated as:

      • SAIFI = total number of customer interruptions / total number of customers served
      • SAIFI is measured in units of interruptions per customer. It is usually measured over the course of a year.

We Rank Among the Best

Currently, 254 of the nation's more than 2,000 public power utilities hold an RP3 designation, with only around 100 achieving the highest rating - diamond status. HBPW has maintained diamond status since 2010, putting us with the most reliable in the nation. Our SAIDI and SAIFI performance measures are ranked among the most reliable electric utilities in Michigan.

Affordable

Operating with efficiency and having a diverse portfolio of electric generation options allows Holland Board of Public Works to maintain rates that are affordable and among the lowest in the State of Michigan.

Additionally, HBPW has the ability to buy and sell power on the open market (a.k.a. the “grid”). Because the market price of electricity fluctuates, our staff monitors that pricing continuously. Based on market pricing, our team makes decisions on the dispatching of our generation resources and buying or selling of electricity to the market in order to ensure that our customers are receiving their electricity at the lowest possible cost.

How It Works

Combined cycle technology employs a number of methods to squeeze the most energy out of every natural gas molecule. This includes recapturing waste heat whenever possible, putting it to use to create more electricity or to run our city’s snowmelt system.

  1. The plant’s two 50MW Combustion Turbine Generators (CTGs) draw in outside air, compress it and combust it with natural gas. The hot exhaust gas propels the turbine blades to turn a generator creating electricity.
  2. The two Heat Recovery Steam Generators (HRSGs) capture heat from the CTGs’ exhaust and use it to convert a closed loop of water into steam.
  3. Pressurized steam from the HRSG’s turns the 45MW Steam Turbine Generator (STG) to generate additional electricity.
  4. Electricity from the plant is stepped up from 13,800 volts to 138,000 volts for distribution to the community’s substations.
  5. A flow of cool water from the cooling towers condenses steam back to liquid after it exits the steam turbine.
  6. Warm water from the condenser can divert to deliver heat to the city’s snowmelt system.
  7. Cooling towers use evaporation to cool a closed loop of hot water from the condenser.

power

HBPW generates, transmits and distributes electricity to approximately 30,000 customers within the City of Holland, Park Township, Holland Township, Laketown Township and Fillmore Township.  Electricity supplied to the community comes from a diverse portfolio of internal and external electric generation facilities including natural gas, coal, and renewable sources. Local generation is from three facilities within the City of Holland.  These generation facilities includes one base load facility (Holland Energy Park) and two peaking stations (48th Street Generation Station and 6th Street Generation Station). Having this local generation capability increases our system’s reliability by reducing dependency on external resources and transmission.  

Holland Energy Park (HEP) uses Combined Cycle Technology, which increases the facility’s efficiency. The exhaust gas from two 50 MW natural gas Combustion Turbine Generators (CTGs) flows into the plant’s two Heat Recovery Steam Generation (HRSG) units where the heat from the exhaust converts water into steam. The steam then flows to a 45 MW steam turbine generator (STG) to create more electricity before it’s cooled back to a liquid in the condenser and cycled back to the HRSGs. This process increases the plant’s thermal efficiency to around 55% (the average coal plant is only 32-42% efficient).  In the winter this efficiency is increased further by utilizing the hot water from the condenser to supply the heat for the snowmelt system in downtown Holland.

48th Street Generation Station consists of three simple cycle combustion turbines. Two of the turbines (units 7 and 8) burn either fuel oil or natural gas, and are capable of generating 38 megawatts each, while the third turbine (unit 9) is capable of generating 84 megawatts. 6th Street Generation Station (unit 6) is an oil-fired combustion turbine capable of generating 23 megawatts of electricity. 

HBPW’s electric transmission and distribution system consists of a 24 mile loop of 138,000 volt transmission lines and more than 600 miles of underground and overhead distribution circuits. These distribution circuits are 12,470/7,200 volts. 


Tree Trimming Program

When tall-growing trees are planted under and near utility lines, they can cause power outages and potentially injure or kill someone when the branches come in contact with wires.

Holland Board of Public Works has an extensive tree trimming program. A tree trimming contractor works to schedule trees trimmings to keep them a safe distance from the overhead electric lines and to maximize the health of the trees. Trees are scheduled to be trimmed on a minimum three year cycle.

Preventing Tree and Utility Conflicts

When planting a new tree, consider how large the tree will be when mature. If the mature height of the tree is greater than 15 feet, then it should not be planted within 15 feet on either side of overhead electric lines.

Many times, the root area of a tree is larger than the branch spread above ground. In areas where there is underground electrical service, trees planted near lines could have their roots damaged if the lines need to be dug up for repairs. One of the greatest dangers to underground lines is when new trees are planted and someone accidentally digs into an underground line. This can cause serious injury and a lengthy utility outage. Be sure to call MISS DIG at 811 before planting or digging.

Contact one of the local nurseries for help in selecting the right tree for the right place. If you have any questions or concerns, and need to speak with someone concerning tree trimming, or have a request for tree trimming, please call HBPW at 616.355.1500.
