Hingham Municipal Lighting Plant breaks peak demand record
Hingham- Two weeks after the Hingham Municipal Lighting Plant (HMLP) set its all time peak for electrical use on July 18th, the high temperatures of early August brought another peak. With the temperatures in the mid to high 90’s, the HMLP set a new all time high of 48.7 MW on Wednesday, August 2nd. This is a four (4) percent increase from just two weeks ago and an eight (8) percent increase from the 2005 peak. “Energy usage continues to increase and we have not seen the full impact of the new Blue Cross/Blue Shield building or the Shipyard project at this time”, said John G. Tzimorangas, General Manager of HMLP. “The Erickson Retirement Community is only one-third built and will add more load to the system as the project moves to full buildout”, commented Tzimorangas. The New England regional system operator, ISO-New England, who manages the six state energy grid, also set a record for electrical demand on Wednesday, August 2nd at 28,040 MW, breaking the previous record of 27,401 MW set the previous day.
The record heat and electrical use only caused minor problems for the HMLP Operations area. Two transformers needed to replaced, one on Otis Hill Road and the other on Leavitt Street as the load on each unit surpassed its capacity to provide electricity. These were the only two cases of heat related outages for HMLP during the record setting day.
In response to this increased need for electricity, HMLP began a project last October to upgrade its Hobart Street substation and completed the project in June of this year. This project included adding a third transformer and a new switch house, which will give HMLP the ability to add eight (8) new circuits in the Town to accommodate the increased energy requirements. “This was an important project for the Light Plant and was completed in a short time frame thanks to the hard work of the Light Plant employees and the contractors working on the project”, said Tzimorangas. “The substation expansion will allow us to continue providing our customers with reliable service and be able to provide the necessary infrastructure to meet the demands of the new customers in Town,” he added.
“The next large project for HMLP is to locate a second substation in Town to diversify our assets. We have begun the process of evaluating potential sites for a new substation and need to continue pursuing a suitable site to give us maximum flexible in providing reliable service to our customers. As the load continues to grow in Town, an additional substation is an important asset to the future supply of the Town”, commented Tzimorangas when asked about the future load growth. The HMLP Light Board reviewed a presentation last September on potential options for locations of a new substation and proximity of transmission lines and chose 2 options to study further and acquire a list of potential available sites for this new station.
HMLP serves 10,000 residential and commercial electric customers in the Town of Hingham. HMLP continues to provide low cost, safe, reliable electricity to the residents of Hingham with a high level of service and customer satisfaction.
