Renewables, including hydro, now account for over 30% of the total global installed power generation capacity and 23% of total global electricity production.<\/p>\n

<\/p>\n

In the past 10 years, wind and solar PV have witnessed an explosive average annual growth of 23% and 50% respectively, although their combined contribution to the global electricity supply is currently only 4%, according to a new report by the World Energy Council launched on 20 September.<\/p>\n

The Report entitled ‘Variable Renewables Integration in Electricity Systems 2016 – How to get it right’<\/a> is published by the World Energy Council in partnership with CESI S.p.A. <\/a>and draws upon 32 country case studies, representing about 90% of installed wind and solar capacity worldwide. <\/p>\n

Renewables have become big business: in 2015 a record US$286 billion was invested in 154GW of new renewables capacity (76% in wind and PV), by far overtaking the investment in conventional generation to which 97GW were added.<\/p>\n

The report is launched as part of the build up to the 23rd World Energy Congress<\/a> which will be held between 10 – 13 October in Istanbul. The topic of renewables in the global energy mix and how they will help accelerate the transition to a low carbon economy is one of the key issues on the first day of the Congress.<\/p>\n

Christoph Frei, Secretary General, World Energy Council,<\/strong> said: “The success of both the development of intermittent renewables and their efficient integration in electricity systems fundamentally depends on the right market design and regulatory framework and solid regional planning to avoid bottlenecks.”<\/p>\n

“We are beyond the tipping point of grand energy transition. Implementing technically and economically sound, stable policies supported by clear carbon price signals will enable this transition and take us a step closer to meeting the climate aspirations agreed at COP21.”<\/p>\n

Improving technologies are driving down capital expenditure of variable renewable energy power plants such as wind and photovoltaic
<\/strong>
Improving technologies and cost reductions are driving down capital expenditure (CAPEX) and operation and maintenance (O&M) costs of variable renewables. Recent data available suggests the lowest auction value for wind is a tariff of US$28\/MWh in Morocco and US$30\/MWh for a solar PV 800 MW plant in Dubai. These exceptionally low values cannot generally be projected to other countries with completely different wind and sun load factors and local costs but show a downward trend. In continental Europe wind and solar load factors are up to 50% lower and local costs considerably higher.<\/p>\n

Alessandro Clerici, Chair of the Renewable Energy Sources Integration in Electricity Systems knowledge network,<\/strong> said: “Appropriate technologies and policies, including regulation and market design play a fundamental role in both development of variable renewables and their efficient integration in electricity systems. Policy solutions are complementary to effective and affordable technology solutions.<\/p>\n

“What works in any particular country depends both on its individual circumstances and the quality of execution of policies. A holistic and long-term approach to system design is key when planning Variable Renewable Energy Sources integration, including honest and transparent cost assessment to incentivise investment and ensure supply security and a robust energy sector regardless of a country’s resources or geographic location.”<\/p>\n

New technologies, operating practices and policy frameworks can increase the penetration of variable renewable energy sources
