By siphoning capital out of the area, and often out of the country where they are installed and, by hogging
existing grid capacity they preclude the development of other more labour intensive renewable energy generation technologies such as bio-mass and anaerobic digestion fuelled systems.
Some analysts expect that
existing grid capacity may be enough to power U.S. electric cars in the near future, yet they do not rule out the possibility of new coal or nuclear plants coming on line if renewable energy sources are not developed
Not exact matches
If individual European countries would disregard national concerns about security of supply, and backup balancing
capacity would be optimally distributed throughout the continent, the necessary
grid capacity extensions can be limited to about triple the
existing European high - voltage
grid.
Each spreadsheet lists the model estimates of
capacity additions (what electric generating
capacity the model and what the states tell the model to include because of regulations); generation (how much the
existing and projected units will produce); prices (including firm power prices, energy prices,
capacity prices, allowance prices, natural gas prices, and renewable energy credit prices); total CO2 emissions; fuel consumption for different fuel types; and transmission flows into and out of the RGGI power
grids.
Technical constraints, load balancing and frequency control issues (on weaker
grids) imposed by limitations in
existing grid structures and
capacities
The
existing commercial biomass power generating industry in the United States, which consists of approximately 1,700 MW (megawatts) of operating
capacity actively supplying power to the
grid, produces about 0.5 % of the U.S. electricity supply.
Like distributed, behind - the - meter solar it is low risk, can be sited near
existing load, increases the resilience of the distribution
grid, and satisfies the powerful consumer craving for solar power; at the same time, it is cheaper, simpler (fewer contracts per kW of
capacity), and more inclusive than behind - the - meter solar.
MNRE said: «Superimposition of wind and solar resource maps shows that there are large areas where both wind and solar have high to moderate potential,» adding that a twin - track approach could smooth output to the
grid and make maximum use of
existing network
capacity.
In fact, thanks to the
existing grid's excess
capacity at night, it should be possible to support up to 30 percent of the nation's vehicles equipped with plug - in batteries of 20 - mile range and not have to expand electricity - generation.
By providing backup and firming
capacity, the expansion of gas - fired power plants can accelerate the integration of intermittent power into
existing electricity
grids.
As plug - in hybrids and electric vehicles become more commonplace, the possibility
exists to utilize the spent EV batteries for power
grid storage after their automotive life, at which point they will still have significant storage
capacity.
The
grid operator replied in a statement, saying the decision means the May BRA for
capacity «will move forward under the
existing rules for the participation of demand response.»
The Ontario Government's energy investment priority should be in new gas, nuclear and / or hydroelectric
capacity, upgrading
existing generating facilities, and in refurbishing transmission
grids.
The group's proposal would allow
existing power plants to maintain and even replace their equipment, and would allow providers to purchase extra power from any source on the national
grid for emergencies and unexpected surges, but it would require that any permanent increase in
capacity come from clean sources like wind and solar.
Making the
grid compatible with an increasing proportion of wind, and the replacement of
existing generating
capacity with wind energy is going to cost hundreds of billions.
