Key takeaways

  • H.F. Lee Energy Complex belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect H.F. Lee Energy Complex to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of H.F. Lee Energy Complex from memory before moving on to harder problems.

Reference excerpt

The H.F. Lee Energy Complex, formerly the Goldsboro Plant, is an electrical power generating complex operated by Duke Energy. The power complex was originally owned by the Carolina Power & Light Company, which inaugurated a coal-fired power plant in 1951. Two more coal plants were added in 1952 and 1962, and then oil-fueled turbines were added in 1967–71. In 2012 these units were shut down and replaced by four gas-fired units. The Quaker Neck Lake was built as a cooling pond for the coal-fired power stations, and is still used to supply cooling water. It was originally impounded by a low dam on the Neuse River, but in 1998 the dam was removed, while the lake remained contained in an earthen wall. This change allowed fish to migrate further upstream for spawning. Ash ponds near the lake hold toxic coal ash. There are plans to remove and recycle or bury the ash.

Power complex Carolina Power & Light Company's Goldsboro Plant in Wayne County began generating electricity in 1951. A second pulverized coal unit was installed in 1952. A third coal unit, which generated 252-MW, was the first coal-fired facility that was completely controlled by an electronic computer. When the third unit came into operation in 1962 the plant was renamed the H.F. Lee Plant after Harry Fitzhugh Lee, a retired district manager with Carolina Power & Light. Between 1967 and 1971 four oil-fueled combustion turbine units were added. In August 1999 Carolina Power and Light Company agreed to buy the Florida Progress Corporation. The merger was complete in 2000, and the combined company was called Progress Energy. In 2009 the company announced that the coal-fired units and combustion turbines at the H.F. Lee Plant would be retired. Progress Energy merged with Duke Energy in July 2012. The three coal-fired units were shut down on 15 September 2012, and the four oil-fueled combustion turbine units ceased operation in October 2012. Wayne County combustion turbines continued to operate at the complex. A new 920-MW gas-fired combined cycle plant began operation in December 2012. The Lee Combined Cycle Plant uses the Quaker Neck Lake as its water source. It has three 180 MW turbines and one 380 MW turbine.

Quaker Neck Lake cooling pond Quaker Neck Lake is 4.7 miles (7.6 km) west of the city center of Goldsboro, North Carolina. It is at 35.3732°N 78.0756°W / 35.3732; -78.0756, at an elevation of 18 metres (59 ft). The lake was made as a cooling pond for the power plant, one of about 48 man-made ponds and lakes in the Neuse River basin. The power complex is to the west of the lake. The lake today lies within a hairpin bend of the Neuse River, but is separated from the river. The river flows eastward along the north of the lake, turns south, then southwest, then runs westward along the south shore of the lake, before turning south and then resuming its generally eastward flow. The 545 acres (221 ha) cooling pond is contained in an earthen wall, and is used to supply cooling water to the power plants. Hurricane Matthew dropped 15 inches (380 mm) of rain in the area in October 2016, which caused the Neuse River to flood. On 12 October 2016 Duke Energy announced that a break 50 to 60 feet (15 to 18 m) wide had developed in the southeast corner of the cooling pond wall. The break was expected to have little impact on the flooded river.

Quaker Neck Dam The low-head Quaker Neck Dam was built in 1952 at Neuse River kilometer 225 to impound cooling water for the steam electric plant. A fish ladder was included. The Dam was 7 feet (2.1 m) high and 260 feet (79 m) long. The dam rose only about 1 metre (3 ft 3 in) above the water during average flow conditions, and was completely submerged in high flow periods. Some studies found that the dam had little impact on fish, which had no difficulty in using the ladder or in crossing the dam in high water periods. Most studies found that only a few fish were able to pass the dam. The dam was classified as a barrier to fish in 1989 by the United States Fish and Wildlife Service. There were delays while the Carolina Power & Light Company looked for an alternative source of cooling water. An alternative was developed between 1993 and 1996, and it was agreed to remove the dam. Deconstruction was undertaken between December 1997 and August 1998. Bruce Babbitt, Secretary of the Interior, swung a sledgehammer to symbolically start removal of the Menominee, Quaker Neck & Cherry Hospital Dams. The Quaker Neck Dam was removed in May 1998. The work cost $222,000. The result was to restore access for anadromous fish to about 78 miles (126 km) of the Neuse River and 925 miles (1,489 km) of tributary streams. Anadromous fish mainly live in saltwater, but return to freshwater to spawn, and include alewife (Alosapseudoharengus), blueback herring (Alosa aestivalis), striped bass (Morone saxatilis) and American shad (Alosa sapidissima). The Cherry Hospital Dam was also removed, which restored another 76 miles (122 km) of streams for use by anadromous fish in Little River, a Neuse tributary. In a 1999 study American shad were equipped with transmitters so their movement could be observed. Of 11 American shad whose transmitters provided useful data, 9 migrated upstream past the former dam site, but all halted within 16 river kilometers of the former dam, long before reaching the next obstacle. However, a comparison of data collected in the 1970s and in 2003–04 show that American shad, hickory shad and striped bass spawning distribution expanded considerably after the dam was removed.

Worked examples

Example 1 — a first encounter with H.F. Lee Energy Complex

Start with the simplest possible case. Write down what H.F. Lee Energy Complex claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to H.F. Lee Energy Complex before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about H.F. Lee Energy Complex ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of H.F. Lee Energy Complex

In research
H.F. Lee Energy Complex appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses H.F. Lee Energy Complex in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
H.F. Lee Energy Complex is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bodies of water of Wayne County, North Carolina, Buildings and structures in Wayne County, North Carolina, Coal-fired power stations in North Carolina, so understanding it makes those chapters shorter.
In everyday life
Look for H.F. Lee Energy Complex outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
