Tomislav BARICEVIC HR Session 5 – Block 2 – Question 28 Barcelona May CONCLUSION Investments in gas network can have significant impact on investments in electricity network Supply of gas to entire Baranja region lowers the necessary electricity network investments by 47% Almost all savings are achieved with the most profitable investment in the gas network Such synergies can be expected when large electricity network investments (like major substation or line) can be avoided by partial substitution of electrical energy consumption with gas
