1979: Challenge and accomplishment

Dear members,

negative decision of the Department of Energy. On June 1,1979, the DOE 4 - o .jdihy l announced its decision to classify Stony ~ Brook as an " existing" power plant. The l favorable decision was the welcome culmina-l ~ tion of seven long months of intensive staff efforts to demonstrate to the federal govern-ment the crucial role Stany Brook plays in N1N1WEC power supply development. After the five month construction delay, construction activity resumed at a dramatic pace. The current status of the Stony Brook 4 Project is a source of pride to N1N1WEC and a credit to the coristruction workforce. The overall construction progress of the Intermediate and Peaking project was esti-mated at 14% at year end. Despite the construction delay, Stony Brook wdl meet its projected commercial on-line dates. Out of 89 contracts necessary to complete the project, thirteen remain to be awarded in 1980. i 2 k \\ {.

l 1 1 l t l l 1 Fuel supply under negotiation Iong-term sources of No. 2 fuel oil were i investigated extensively in 1979. Invitations to bid were mailed to potential oil suppliers in September. Responses from several firms have been positive and contract negotiations are proceeding. MMWEC's primary objective is to have more than one oil supplier with a secure source of crude oil and refinery capability. A principal concern is that any i source of fuel be independent from existing supply in New England. l Supplying MMWEC's oil requirements will a depend upon market conditions and govern-ment regulations; because of the uncertainty j of on orpply, MMWEC is strengthening its commitmen.: to study alternate fuel sources, i i D E. including surplus natural gas and synthetic 1 i fuels. A preliminary study of alternate fuels was completed in 1979. MMWEC is negotiating for the transport of fuel oil through two common carrier pipelines. The location of the Stony Brook Project allows inexpensive delivery since I both pipelines are in the plant vicinity. One pipeline originates in the port of New Haven, Co n ut and another pipeline extends from the port of East Providence, Rhode Island. Dedicated storage capacity and terminalling services are anticipated in New Haven, with alternate capacity in East Providence.

l l The Treasurer's statement l MMWEC continued the financing of the projects in its Power Supply Program during 1979 through issuance of bonds and notes. On January 1,1979 MMWEC had notes outstanding, primarily issued to finance the Stony Brook Projects, amounting to approxi-3 mately $70 million. On August 16,1979, MMWEC sold $150.000,0001979 Series A Bonds for the Stony Brook Intermediate l Project. Primarily ' ugh the application of a portion of the b : proceeds, notes outstanding were rutuced to $5,000,000 issued for the Stony Brook Peaking Project. Notes outstanding at December 31,1979 amounted to $35,000,000, all of which were issued for the Peaking Project. warv The 1979 Series A Bonds were MMWEC's fifth bond issue. Total revenne bonds issued and outstanding at December 31,1979 amounted to $560,870,000. MMWEC's bonds are rated "A" by Moody's and "A+" by Standard & Poors. As a result of MMWEC's conservative m financing practices with respect to permanent financing for projects under construction, in W most cases estimated construction cash flow requirements and the interest requirements on long-term debt issued for such projects t have been funded through 1981 or longer.
